    Tham JS, Zanuddin H
    Southeast Asian J. Trop. Med. Public Health, 2015 Jul;46(4):669-79.
    PMID: 26867387
    Abstract. This paper examines the effectiveness of media in public awareness of the HIV/AIDS issue among the public in an area in central Selangor, comprising Kuala Lumpur and its surroundings and suburbs in Malaysia. Cross-sectional survey questionnaires were distributed to 384 respondents about accessing the public awareness of modes of HIV transmission, perceptions and attitudes towards people living with HIV/AIDS, as well as people's understanding about government policies to curb HIV/AIDS. Health care practitioners and newspapers were the preferred sources of information seeking on HIV/AIDS among the public. Most of the respondents were aware of the modes of HIV transmission. However, they were some respondents who still have misconceptions about the modes of transmission. Most of the respondents were not aware about the government's significant policies to address HIV/AIDS in the region. Overall, the respondents had certain knowledge about HIV transmission modes and moderate positive perceptions and attitudes towards people living with HIV/AIDS. Future studies should be conducted to examine about who sets the agenda in the media, and apart from gatekeepers, who are the real decision makers in deciding what is important to inform the public.

    Introduction: Under 5 mortality is a leading indicator of the level of child health and overall development of a coun-try. In Malaysia, progressive reduction has been observed from 1990 however since 2000 progress has been static. Further understanding about this trend is crucial. The objective of this study was to identify causes of mortality for better policy development in order to further reduce this rate. Methods: Analysis of mortality trends was done using data from Department of Statistics and causes of mortality using data collected through the Stillbirth and Under 5 Mortality Reporting System (SU5MR) in 2016. Results: The trend for Under 5 mortality rate between 2006 till 2016 is still plateaued and hovered between 8 to 9 per 1000 live births at the national level. High percentage of death is seen among the neonatal group (51%), followed by children 28 days to 1year (31%) and toddlers 1-4 years (18%). Percentage of preventable deaths increased with age i.e. 21% among neonates, 41% among children 28 days to 1year and 48% among toddlers. The leading causes of death are conditions from perinatal period (34.4%), congen-ital malformation (30%), injuries and external causes (6.4%), respiratory (5.6%) and certain infectious and parasitic disease (5.1%). Conclusion: To further reduce under -5 mortality focus needs to be on preventable deaths; to reduce neonatal deaths will require political commitment to ensure adequate resources; interagency collaboration is needed to reduce toddler mortality and family and community awareness on prevention of injury and infection.

    Antibiotic resistance in pathogenic bacteria is a major health challenge, as Infectious Diseases Society of America (IDSA) has recognized that the past simply drugs susceptible pathogens are now the most dangerous pathogens due to their nonstop growing resistance towards conventional antibiotics. Therefore, due to the emergence of multi-drug resistance, the bacterial infections have become a serious global problem. Acute infections feasibly develop into chronic infections because of many factors; one of them is the failure of effectiveness of antibiotics against superbugs. Modern research of two-dimensional nanoparticles and biopolymers are of great interest to attain the intricate bactericidal activity. In this study, we fabricated an antibacterial nanocomposite consisting of representative two-dimensional molybdenum disulfide (2D MoS2) nanoparticles. Polyhydroxyalkanoate (PHA) and chitosan (Ch) are used to encapsulate MoS2 nanoparticles into their matrix. This study reports the in vitro antibacterial activity and host cytotoxicity of novel PHA-Ch/MoS2 nanocomposites. PHA-Ch/MoS2 nanocomposites were subjected to time-dependent antibacterial assays at various doses to examine their antibacterial activity against multi-drug-resistant Escherichia coli K1 (Malaysian Type Culture Collection 710859) and methicillin-resistant Staphylococcus aureus (MRSA) (Malaysian Type Culture Collection 381123). Furthermore, the cytotoxicity of nanocomposites was examined against spontaneously immortalized human keratinocyte (HaCaT) cell lines. The results indicated significant antibacterial activity (p value

    Sadiq MA, Hassan L, Aziz SA, Zakaria Z, Musa HI, Amin MM
    Vet World, 2018 Nov;11(10):1404-1408.
    PMID: 30532493 DOI: 10.14202/vetworld.2018.1404-1408
    Background: Melioidosis is a fatal emerging infectious disease of both man and animal caused by bacteria Burkholderia pseudomallei. Variations were suggested to have existed among the different B. pseudomallei clinical strains/genotypes which may implicate bacterial susceptibility and resistance toward antibiotics.

    Aim: This study was designed to determine whether the phenotypic antibiotic resistance pattern of B. pseudomallei is associated with the source of isolates and the genotype.

    Materials and Methods: A collection of 111 B. pseudomallei isolates from veterinary cases of melioidosis and the environments (soil and water) were obtained from stock cultures of previous studies and were phylogenetically characterized by multilocus sequence typing (ST). The susceptibility to five antibiotics, namely meropenem (MEM), imipenem, ceftazidime (CAZ), cotrimoxazole (SXT), and co-amoxiclav (AMC), recommended in both acute and eradication phases of melioidosis treatment were tested using minimum inhibitory concentration antibiotics susceptibility test.

    Results: Majority of isolates were susceptible to all antibiotics tested while few resistant strains to MEM, SXT, CAZ, and AMC were observed. Statistically significant association was found between resistance to MEM and the veterinary clinical isolates (p<0.05). The likelihood of resistance to MEM was significantly higher among the novel ST 1130 isolates found in veterinary cases as compared to others.

    Conclusion: The resistance to MEM and SXT appeared to be higher among veterinary isolates, and the novel ST 1130 was more likely to be resistant to MEM as compared to others.

  6. Fulltext The Plasmodium knowlesi Pk41 surface protein diversity, natural selection, sub population and geographical clustering: a 6-cysteine protein family member
    Ahmed MA, Chu KB, Quan FS
    PeerJ, 2018;6:e6141.
    PMID: 30581686 DOI: 10.7717/peerj.6141
    Introduction: The zoonotic malaria parasite Plasmodium knowlesi has currently become the most dominant form of infection in humans in Malaysia and is an emerging infectious disease in most Southeast Asian countries. The P41 is a merozoite surface protein belonging to the 6-cysteine family and is a well-characterized vaccine candidate in P. vivax and P. falciparum; however, no study has been done in the orthologous gene of P. knowlesi. This study investigates the level of polymorphism, haplotypes and natural selection of pk41 genes in clinical isolates from Malaysia.

    Method: Thirty-five full-length pk41 sequences from clinical isolates of Malaysia along with four laboratory lines (along with H-strain) were downloaded from public databases. For comparative analysis between species, orthologous P41 genes from P. falciparum, P. vivax, P. coatneyi and P. cynomolgi were also downloaded. Genetic diversity, polymorphism, haplotype and natural selection were determined using DnaSP 5.10 software. Phylogenetic relationships between Pk41 genes were determined using MEGA 5.0 software.

    Results: Analysis of 39 full-length pk41 sequences along with the H-strain identified 36 SNPs (20 non-synonymous and 16 synonymous substitutions) resulting in 31 haplotypes. Nucleotide diversity across the full-length gene was low and was similar to its ortholog in P. vivax; pv41. Domain-wise amino acid analysis of the two s48/45 domains indicated low level of polymorphisms for both the domains, and the glutamic acid rich region had extensive size variations. In the central domain, upstream to the glutamate rich region, a unique two to six (K-E)n repeat region was identified within the clinical isolates. Overall, the pk41 genes were indicative of negative/purifying selection due to functional constraints. Domain-wise analysis of the s48/45 domains also indicated purifying selection. However, analysis of Tajima's D across the genes identified non-synonymous SNPs in the s48/45 domain II with high positive values indicating possible epitope binding regions. All the 6-cysteine residues within the s48/45 domains were conserved within the clinical isolates indicating functional conservation of these regions. Phylogenetic analysis of full-length pk41 genes indicated geographical clustering and identified three subpopulations of P. knowlesi; one originating in the laboratory lines and two originating from Sarawak, Malaysian Borneo.

    Conclusion: This is the first study to report on the polymorphism and natural selection of pk41 genes from clinical isolates of Malaysia. The results reveal that there is low level of polymorphism in both s48/45 domains, indicating that this antigen could be a potential vaccine target. However, genetic and molecular immunology studies involving higher number of samples from various parts of Malaysia would be necessary to validate this antigen's candidacy as a vaccine target for P. knowlesi.

  7. An infectious full-length cDNA clone of duck Tembusu virus, a newly emerging flavivirus causing duck egg drop syndrome in China
    Li S, Zhang L, Wang Y, Wang S, Sun H, Su W, et al.
    Virus Res, 2013 Jan;171(1):238-41.
    PMID: 23116594 DOI: 10.1016/j.virusres.2012.10.019
    Duck Tembusu virus (TMUV) is a recently identified pathogenic flavivirus that causes severe egg drop and encephalitis in Chinese ducks and geese. It has been found to be most closely related to the mosquito-origin Tembusu virus and chicken Sitiawan virus reported in Malaysia. However, the ecological characteristics and the pathogenesis of duck TMUV are largely unknown. We report the construction of full-length cDNA clone of duck TMUV strain JXSP. The virus genome was reverse transcribed, amplified as seven overlapping fragments and successively ligated into the low copy number vector pWSK29 under the control of a T7 promoter. Transfection of BHK-21 cells with the transcribed RNA from the full-length cDNA clone resulted in production of highly infectious progeny virus. In vitro growth characteristics in BHK-21 cells and virulence in ducklings and BALB/c mice were similar for the rescued and parental viruses. This stable infectious cDNA clone will be a valuable tool for studying the genetic determinants of duck TMUV.

  8. Fulltext Evaluation of a Multidisciplinary Antimicrobial Stewardship Program in a Saudi Critical Care Unit: A Quasi-Experimental Study
    Haseeb A, Faidah HS, Al-Gethamy M, Iqbal MS, Barnawi AM, Elahe SS, et al.
    Front Pharmacol, 2020;11:570238.
    PMID: 33776750 DOI: 10.3389/fphar.2020.570238
    Background: Antimicrobial stewardship programs (ASPs) are collaborative efforts to optimize antimicrobial use in healthcare institutions through evidence-based quality improvement strategies. With regard to critically ill patients, appropriate antimicrobial usage is of significance, and any delay in therapy increases their risk of mortality. Therefore, the implementation of structured multidisciplinary ASPs in critical care settings is of the utmost importance to promote the judicious use of antimicrobials. Methods: This quasi-experimental study evaluating a multidisciplinary ASP in a 20-bed critical care setting was conducted from January 1, 2016 to July 31, 2017. Outcomes were compared nine months before and after ASP implementation. The national antimicrobial stewardship toolkit by Ministry of health was reviewed and the hospital antibiotic prescribing policy was accordingly modified. The antimicrobial stewardship algorithm (Start Smart and Then Focus) and an ASP toolkit were distributed to all intensive care unit staff. Prospective audit and feedback, in addition to prescribing forms for common infectious diseases and education, were the primary antimicrobial strategies. Results: We found that the mean total monthly antimicrobial consumption measured as defined daily dose per 100 bed days was reduced by 25% (742.86 vs. 555.33; p = 0.110) compared to 7% in the control condition (tracer medications) (35.35 vs. 38.10; p = 0.735). Interestingly, there was a negative impact on cost in the post-intervention phase. Interestingly, the use of intravenous ceftriaxone measured as defined daily dose per 100 bed days was decreased by 82% (94.32 vs. 16.68; p = 0.008), whereas oral levofloxacin use was increased by 84% (26.75 vs. 172.29; p = 0.008) in the intensive care unit. Conclusion: Overall, involvement of higher administration in multidisciplinary ASP committees, daily audit and feedback by clinical pharmacists and physicians with infectious disease training, continuous educational activities about antimicrobial use and resistance, use of local antimicrobial prescribing guidelines based on up-to-date antibiogram, and support from the intensive care team can optimize antibiotic use in Saudi healthcare institutions.

    MyJurnal
    Introduction: Poor hygiene practice is an important factor that lead to morbidity and mortality among young chil- dren which are common among the indigenous population due to the lack of access to health services and their unique beliefs and practices. This study aimed to identify the socio-demographic determinants of hygiene practices among the indigenous (known as Orang Asli in Malaysia) primary caregivers of children under the age of three in Malaysia. Methods: A cross-sectional study was conducted among 166 primary caregivers of Orang Asli children of below three years old in Kuala Langat District. Data was collected using a validated and pre-tested questionnaire via face-to-face interviews with individual respondents. The questionnaire consisted of two main sections: sociodemo- graphics and hygiene practice. Results: A majority of the Orang Asli primary caregivers had good hygiene practices (78.9%). The number of children under five years old living at home was significantly associated with hygiene prac- tice and it was the only significant determinant or predictor of good hygiene practice among the Orang Asli primary caregivers. Conclusion: The number of children under five years old living at home is an important factor to ensure good hygiene practices among the primary caregivers of Orang Asli children. This factor need to be taken into con- sideration in monitoring children health status by the health staff by emphasizing the importance of hygiene practice in the prevention of infectious diseases and malnutrition among Orang Asli children.

    MyJurnal
    Dengue and malaria infections are common mosquito-borne infectious diseases in tropical and subtropical regions. The clinical manifestations of dengue and malaria often mimic each other, causing the predicament of early diagnosis without laboratory investigations. Concurrent dengue and malaria infection are often rare scenarios when both diseases occur in a particular patient at the same time. A high index of suspicion is therefore required to establish an early diagnosis to ensure complete success in its management. This case report is about concurrent dengue and malaria infection in a 54-year-old Pakistani man who presented with high-grade fever for three days before admission. On examination, he was febrile (38.8°C) with no other findings. His blood investigations were positive for NS1 antigen and IgM but negative for IgG. His peripheral blood film revealed the presence of Plasmodium vivax. He was treated for dengue fever with supportive management and started with oral Riamet (artemether and lumefantrine) along with oral primaquine 30 mg daily for two weeks’ duration. Following treatment, the patient demonstrated progressive clinical improvement and was subsequently discharged back to the community clinic for the continuation of care.

  11. Fulltext Politics of disease control in Africa and the critical role of global health diplomacy: A systematic review
    Chattu VK, Knight WA, Adisesh A, Yaya S, Reddy KS, Di Ruggiero E, et al.
    Health Promot Perspect, 2021;11(1):20-31.
    PMID: 33758752 DOI: 10.34172/hpp.2021.04
    Background: Africa is facing the triple burden of communicable diseases, non-communicable diseases (NCDs), and nutritional disorders. Multilateral institutions, bilateral arrangements, and philanthropies have historically privileged economic development over health concerns. That focus has resulted in weak health systems and inadequate preparedness when there are outbreaks of diseases. This review aims to understand the politics of disease control in Africa and global health diplomacy's (GHD's) critical role. Methods: A literature review was done in Medline/PubMed, Web of Science, Scopus, Embase, and Google scholar search engines. Keywords included MeSH and common terms related to the topics: "Politics," "disease control," "epidemics/ endemics," and "global health diplomacy" in the "African" context. The resources also included reports of World Health Organization, United Nations and resolutions of the World Health Assembly (WHA). Results: African countries continue to struggle in their attempts to build health systems for disease control that are robust enough to tackle the frequent epidemics that plague the continent. The politics of disease control requires the crafting of cooperative partnerships to accommodate the divergent interests of multiple actors. Recent outbreaks of COVID-19 and Ebola had a significant impact on African economies. It is extremely important to prioritize health in the African development agendas. The African Union (AU) should leverage the momentum of the rise of GHD to (i) navigate the politics of global health governance in an interconnected world(ii) develop robust preparedness and disease response strategies to tackle emerging and reemerging disease epidemics in the region (iii) address the linkages between health and broader human security issues driven by climate change-induced food, water, and other insecurities (iv) mobilize resources and capacities to train health officials in the craft of diplomacy. Conclusion: The AU, Regional Economic Communities (RECs), and African Centres for Disease Control should harmonize their plans and strategies and align them towards a common goal that integrates health in African development agendas. The AU must innovatively harness the practice and tools of GHD towards developing the necessary partnerships with relevant actors in the global health arena to achieve the health targets of the Sustainable Development Goals.

  12. Fulltext Plasmodium-a brief introduction to the parasites causing human malaria and their basic biology
    Sato S
    J Physiol Anthropol, 2021 Jan 07;40(1):1.
    PMID: 33413683 DOI: 10.1186/s40101-020-00251-9
    Malaria is one of the most devastating infectious diseases of humans. It is problematic clinically and economically as it prevails in poorer countries and regions, strongly hindering socioeconomic development. The causative agents of malaria are unicellular protozoan parasites belonging to the genus Plasmodium. These parasites infect not only humans but also other vertebrates, from reptiles and birds to mammals. To date, over 200 species of Plasmodium have been formally described, and each species infects a certain range of hosts. Plasmodium species that naturally infect humans and cause malaria in large areas of the world are limited to five-P. falciparum, P. vivax, P. malariae, P. ovale and P. knowlesi. The first four are specific for humans, while P. knowlesi is naturally maintained in macaque monkeys and causes zoonotic malaria widely in South East Asia. Transmission of Plasmodium species between vertebrate hosts depends on an insect vector, which is usually the mosquito. The vector is not just a carrier but the definitive host, where sexual reproduction of Plasmodium species occurs, and the parasite's development in the insect is essential for transmission to the next vertebrate host. The range of insect species that can support the critical development of Plasmodium depends on the individual parasite species, but all five Plasmodium species causing malaria in humans are transmitted exclusively by anopheline mosquitoes. Plasmodium species have remarkable genetic flexibility which lets them adapt to alterations in the environment, giving them the potential to quickly develop resistance to therapeutics such as antimalarials and to change host specificity. In this article, selected topics involving the Plasmodium species that cause malaria in humans are reviewed.

    Osteomyelits due to concurrent multi-drug resistance organisms is difficult to treat for any surgeon and infectious disease physician. An eleven-year-old boy presenting with an open fracture of the left radius and ulna after a fall in a stagnant wet field. Despite prophylactic antibiotics and surgical intervention, the open wound was infected, and Chromobacterium violaceum as well as Klebsiella pneumoniae were isolated. He was treated with six weeks of parenteral cefepime and amikacin and was discharged upon clinical improvement. Unfortunately, chronic osteomyelitis set in with persistent sinus drainage. He then underwent a second procedure for debridement of the wound and Burkholderia pseudomallei was isolated. Parenteral antibiotic therapy was initiated progressing with a marked improvement. However, the long course of antibiotics had exhausted the patient and his family, leading to a premature interruption of the parenteral antibiotic. Despite the suboptimal antibiotic course, there were no signs of relapsed osteomyelitis during subsequent review. The timely surgical intervention with appropriate sampling for subsequent microorganism isolation guided the suitability of the treatment line.

    Japanese encephalitis virus (JEV) is a representative virus of the JEV serogroup in genus Flavivirus, family Flaviviridae. JEV is a mosquito-borne virus that causes Japanese encephalitis (JE), one of the most severe viral encephalitis diseases in the world. JEV is divided into five genotypes (G1-G5), and each genotype has its own distribution pattern. However, the distribution of different JEV genotypes has changed markedly in recent years. JEV G1 has replaced G3 as the dominant genotype in the traditional epidemic areas in Asia, while G3 has spread from Asia to Europe and Africa and caused domestic JE cases in Africa. G2 and G5, which were endemic in Malaysia, exhibited great geographical changes as well. G2 migrated southward and led to prevalence of JE in Australia, while G5 emerged in China and South Korea after decades of silence. Along with these changes, JE occurred in some non-traditional epidemic regions as an emerging infectious disease. The regional changes in JEV pose a great threat to human health, leading to huge disease burdens. Therefore, it is of great importance to strengthen the monitoring of JEV as well as virus genotypes, especially in non-traditional epidemic areas.

    Plants with medicinal properties have been used in the treatment of several infectious diseases, including Acanthamoeba infections. The medicinal properties of Cambodian plant extracts; Annona muricata and Combretum trifoliatum were investigated against Acanthamoeba triangularis. A total of 39 plant extracts were evaluated and, as a result, 22 extracts showed positive anti-Acanthamoeba activity. Of the 22 extracts, 9 and 4 extracts showed anti-Acanthamoeba activity against trophozoites and cysts of A. triangularis, respectively. The minimum inhibitory concentration of A. muricata and C. trifoliatum extracts against trophozoites and cysts was 500 and 1,000 μg/mL, respectively. The combination of A. muricata at 1/4×MIC with chlorhexidine at 1/8×MIC demonstrated a synergistic effect against trophozoites, but partial synergy against cysts. A 40% reduction in trophozoites and 60% of cysts adhered to the plastic surface treated with both extracts at 1/2×MIC were noted comparing to the control (P < 0.05). Furthermore, a reduction of 80% and 90% of trophozoites adhered to the surface was observed after pre-treatment with A. muricata and C. trifoliatum extracts, respectively. A 90% of cysts adhered to the surface was decreased with pre-treatment of A. muricata at 1/2×MIC (P < 0.05). A 75% of trophozoites and cysts from Acanthamoeba adhered to the surface were removed after treatment with both extracts at 4×MIC (P < 0.05). In the model of contact lens, 1 log cells/mL of trophozoites and cysts was significantly decreased post-treatment with both extracts compared to the control. Trophozoites showed strong loss of acanthopodia and thorn-like projection pseudopodia, while cysts demonstrated retraction and folded appearance treated with both extracts when observed by SEM, which suggests the potential benefits of the medicinal plants A. muricata and C. trifoliatum as an option treatment against Acanthamoeba infections.

    Approximately one in five children worldwide suffers from childhood malnutrition and its complications, including increased susceptibility to inflammation and infectious diseases. Due to improved early interventions, most of these children now survive early malnutrition, even in low-resource settings (LRS). However, many continue to exhibit neurodevelopmental deficits, including low IQ, poor school performance, and behavioral problems over their lifetimes. Most studies have relied on neuropsychological tests, school performance, and mental health and behavioral measures. Few studies, in contrast, have assessed brain structure and function, and to date, these have mainly relied on low-cost techniques, including electroencephalography (EEG) and evoked potentials (ERP). The use of more advanced methods of neuroimaging, including magnetic resonance imaging (MRI) and functional near-infrared spectroscopy (fNIRS), has been limited by cost factors and lack of availability of these technologies in developing countries, where malnutrition is nearly ubiquitous. This report summarizes the current state of knowledge and evidence gaps regarding childhood malnutrition and the study of its impact on neurodevelopment. It may help to inform the development of new strategies to improve the identification, classification, and treatment of neurodevelopmental disabilities in underserved populations at the highest risk for childhood malnutrition.

    Dengue, a very widespread mosquito-borne infectious disease caused by Aedes aegypti virus, has been occurring during the monsoons every year. The prevalence and incidence of dengue fever and death due to its complications have been increased drastically in these recent years in Bangladesh, Philippines, Thailand, Brazil, and India. Recently, dengue had spread in an epidemic form in Bangladesh, Thailand, and Philippines. Although the infection affected a large number of people around the world, there is no established specific and effective treatment by synthetic medicines. In this subcontinent, Malaysia could effectively control its incidences and death of patients using alternative medication treatment mainly prepared from Carica papaya L. leaves along with proper care and hospitalization. Papaya leaves, their juice or extract, as well as their different forms of preparation have long been used traditionally for treating dengue fever and its complications to save patients' lives. Although it is recommended by traditional healers, and the general public use Papaya leaves juice or their other preparations in dengue fever, this treatment option is strictly denied by the physicians offering treatment in hospitals in Bangladesh as they do not believe in the effectiveness of papaya leaves, thus suggesting to patients that they should not use them. In Bangladesh, 1,01,354 dengue patients have been hospitalized, with 179 deaths in the year 2019 according to information from the Institute of Epidemiology, Disease Control, and Research as well as the Directorate General of Health Services of Bangladesh. Most of the patients died because of the falling down of platelets to dangerous levels and hemorrhage or serious bleeding. Therefore, this paper aims to critically review the scientific basis and effectiveness of Carica papaya L. leaves in treating dengue fever based on preclinical and clinical reports. Thrombocytopenia is one of the major conditions that is typical in cases of dengue infection. Besides, the infection and impairment of immunity are concerned with dengue patients. This review summarizes all the scientific reports on Carica papaya L. for its ability on three aspects of dengue: antiviral activities, prevention of thrombocytopenia and improvement of immunity during dengue fever.

    Intestinal parasitic infections (IPIs) are among the most important infectious diseases in Iran. A cross sectional study was designed to determine frequency of intestinal parasites among referrals to a large teaching hospital in Khuzestan, Southwest of Iran, 2017. A total number of 5613 stool samples were examined through direct smear and formalin-ether concentration methods to detect possible parasitic infections. Samples consisted of 2643 (47.09%) male and 2970 (52.91%) female. A total of 1468 (26.15%) samples were positive (13.11% male and 13.4% female) and 4145 (73.85%) were negative. The results also showed that 255 of samples had more than one type of parasite (mix infections). Counting single and mix parasite infections, the total number of positive cases reached to 1723. Helminthes parasites were present in 12 (0.7%) cases, while intestinal protozoan parasites were in 1711 (99.3%) cases. Almost equally, pathogenic and nonpathogenic parasites infected 860 (49.91%) and 863 (50.09%) of patients, respectively. The frequency for helminthes was determined at 0.52% with Hymenolepis nana and Enterobius vermicularis however, Giardia lamblia in 38.54% and Entamoeba histolytica/dispar at 10.68% were concluded as protozoa elements. The IPIs frequency was recorded in female and male patients at 49.16% and 50.14%, respectively. According to the current results the infection rate of intestinal parasites has been significantly reduced especially for helminths infections in this region possibly due to public attention to health issues such as; increased awareness of people, improvement of sanitation, seasonal variations, health education and personal hygiene.

    The state of Johore, Malaysia had been hit by the worst flood in the Malaysian modern history on the 19th December 2006 (first wave) and the 12th January 2007 (second wave) affecting all the eight districts. A total number of 157,018 and 155,368 Johore population had been displaced by the first and the second wave event respectively. The Johore State Health Department activated the Flood Action Plan which include mobilising medical teams to conduct daily clinical examinations on the flood victims and health teams to inspect flood relief centres, food premises and homes at flood-hit areas with regard to prevent and control communicable diseases. The spreadsheet format was used to collect data on diseases, injury and death throughout the Johore flood disaster period starting from the 19th December 2006 until 19th February 2007. Analyses showed that 19,670 flood victims (36.3%) had communicable diseases and 34,530 (67.0%) had non-communicable diseases. As for the communicable diseases and symptoms/syndromes related to communicable disease, 41.3% were acute respiratory infections (ARI) followed by 25.9% skin infections, 19.1% fever, 10.1% acute gastroenteritis (AGE) and 3.0% acute conjunctivitis. Other infectious diseases include 61 notifiable diseases (46 food poisoning, 14 dengue fever and one tuberculosis), 20 leptospirosis (with two deaths), 20 chicken pox and two melioidosis cases. The Batu Pahat district had the highest incidence for the majority of the communicable diseases because of the prolonged flooding period. No cholera, typhoid, malaria, measles or hand-foot-mouth disease (HFMD) cases were detected among the Johore flood victims. Trends of disease incidence follow the number of evacuees placed in the relief centres corresponding to respective wave. A total of 507 flood victims had physical injuries related to flood mostly due to fall onto wet floor at the relief centres. Fifteen deaths due to drowning were mainly caused by accidental fall into the flood water. The incidence of communicable diseases encountered had been appropriately anticipated and managed attributed to enhanced public health control programmes augmented by syndromic and laboratory surveillance on potentialy fatal infectious diseases. Equal emphasis should be given to the surveillance and control of chronic diseases.

    Background : Safe potable water is critical during and post flood. In the pre-flood period, Johore has an excellent, systematic and comprehensive water supply system. More than 98.6% of Johore population received treated water supply from the water treatment plants.
    Methodology : Data collection was performed by conducting additional water sampling at routine sampling stations as well as the flood relief centres, water tankers (lorries) and static water tanks. Water treatment plant outlet and water tanker inlet shall have a minimum level of 2.0 mg/l of residual chlorine so that reticulation, water tanker outlets and static water tanks would have at least 0.5 mg/l as a measure to prevent the incidence of water borne diseases. Sampling was done everyday to monitor water quality at the flood relief centres as well as flood-hit areas. Inspections and surveillance on sanitation were also conducted on latrines, solid waste disposal systems and on the surrounding environment.
    Results : A total of 6,283 water samples had been collected during and post flood. Violations on E. coli, turbidity and residual chlorine were 0.8%, 0.6% and 4.0% respectively with the Kluang district recorded the highest percentages for all the three parameters. A number of 621 wells had been inspected with 378 of them (60.9%) had been chlorinated. In order to ensure environmental cleanliness, 26,815 houses in 708 villages had been visited. Out of them, 2,011 houses (7.5%) were not satisfactory. Sanitation inspections found that 1,778 latrines, 2,719 domestic water sewerage systems and 2,955 solid waste disposal systems were under substandard conditions thus remedial actions had been taken immediately.
    Conclusion : Although the flood disaster was massive with prolonged flooding period, however, an overall quality status on treated water supply was satisfactory whilst sanitary hygiene was under control. Hence, the incidence of communicable disease especially water borne diseases would not progress into serious outbreak, in fact, neither cholera nor typhoid was reported during the Johore flood disaster.
