    A strategic multilateral dialogue related to biosecurity risks in Southeast Asia, established in 2014, now includes participants from Singapore, Malaysia, Indonesia, Thailand, Philippines, and the United States. This dialogue is conducted at the nonministerial level, enabling participants to engage without the constraints of operating in their official capacities. Participants reflect on mechanisms to detect, mitigate, and respond to biosecurity risks and highlight biosecurity issues for national leadership. Participants have also identified factors to improve regional and global biosecurity, including improved engagement and collaboration across relevant ministries and agencies, sustainable funding for biosecurity programs, enhanced information sharing for communicable diseases, and increased engagement in international biosecurity forums.

    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.

    The microbes that cause infectious diseases are complex, dynamic, and constantly evolving. They reproduce rapidly, mutate frequently, breach species barriers, adapt with relative ease to new hosts and new environments, and develop resistance to the drugs used to treat them. In their article "Meeting the challenge of epidemic infectious diseases outbreaks: an agenda for research", Kai-Lit Phua and Lai Kah Lee clearly demonstrate how social, behavioural and environmental factors, linked to a host of human activities, have accelerated and amplified these natural phenomena. By reviewing published and non-published information about outbreaks of Nipah virus in Malaysia, severe acute respiratory syndrome (SARS) and avian influenza in Asia, and the HIV pandemic, they provide a series of examples that demonstrate the various social, behavioural and environmental factors of these recent infectious disease outbreaks. They then analyse some of these same determinants in important historical epidemics and pandemics such as plague in medieval Europe, and conclude that it is important to better understand the social conditions that facilitate the appearance of diseases outbreaks in order to determine why and how societies react to outbreaks and their impact on different population groups.

    Centuries of scientific advances and developments in biomedical sciences have brought us a long way to understanding and managing disease processes, by reducing them to simplified cause-effect models. For most of the infectious diseases known today, we have the methods and technology to identify the causative agent, understand the mechanism by which pathology is induced and develop the treatment (drugs, vaccines, medical or surgical procedures) to cure, manage or control.Disease, however, occurs within a context of lives fraught with complexity. For any given infectious disease, who gets it, when, why, the duration, the severity, the outcome, the sequelae, are bound by a complex interplay of factors related as much to the individual as it is to the physical, social, cultural, political and economic environments. Furthermore each of these factors is in a dynamic state of change, evolving over time as they interact with each other. Simple solutions to infectious diseases are therefore rarely sustainable solutions. Sustainability would require the development of interdisciplinary sciences that allow us to acknowledge, understand and address these complexities as they occur, rather than rely solely on a form of science based on reducing the management of disease to simple paradigms.In this review we examine the current global health responses to the 'neglected' tropical diseases, which have been prioritised on the basis of an acknowledgment of the complexity of the poverty-disease cycle. However research and interventions for neglected tropical diseases, largely neglect the social and ecological contextual, factors that make these diseases persist in the target populations, continuing instead to focus on the simple biomedical interventions. We highlight the gaps in the approaches and explore the potential of enhanced interdisciplinary work in the development of long term solutions to disease control.

    At this moment, public health authorities, physicians and scientists around the world are struggling to cope with a severe and rapidly spreading new disease in humans called severe acute respiratory syndrome, or SARS. According to World Health Organisation (WHO) this appears to be the first severe and easily transmissible new disease to emerge in the 21st century. Though much about the disease remains poorly understood, including the details of the causative virus, we do know that it has features that allow it to spread rapidly along international air travel routes. As of 10 May 2003, a cumulative 7296 probable SARS cases with 526 deaths have been reported from 30 countries on three continents (WHO, ProMED). In the past week, more than 1000 new probable cases and 96 deaths were reported globally. This represents an increase of 119 new cases and 8 new deaths compared with 9 May 2003 (China (85), Taiwan (23), and Hong Kong (7) represented the overwhelming majority, with one additional case each reported from France, Malaysia, Singapore, and the United States). Only in China, as of 10 May 2003 (WHO) total of 4884 with 235 deaths have been reported. Some outbreaks have reassuring features.

    Rubella is an acute and contagious disease which is mainly characterized by fever, rash, and cervical lymphadenopathy. This contagious disease spreads easily through nasopharyngeal secretions, droplet or direct contact with patients. Meanwhile clinical features of scarlet fever include a sore throat, skin rash and strawberry tongue. A descriptive study was conducted to describe the epidemiological characteristic of diseases at a Training Camp in Mersing. Data obtained on demographic details, onset and time of fever and rash or contact with ill person 14 to 21 days prior to symptoms. Screening and interview conducted for all suspected cases of Rubella. 47.4% of the cases presented on 5th June 2012 followed by 15.8% on 11th June 2012 and 13.5% on 12th June 2012. Maculo papular rash was the predominant presenting symptom among students with acute infection in this outbreak (100%) followed by fever (36.8%). Measles specific IgM was not detected in the serum taken but rubella specific IgM was detected in 66.7% (6/19) of samples. 55% (11/20) were positive for ASOT. 4 trainees had Rubella and Scarlet Fever co-infection. It was found out that the outbreak occurred among 391 residents in the camp who shared common places for activities such as lecture, physical activity and meal. Rapid dissemination was due to overcrowded environment and close contact during common activities of the residents. Theoretically co-infection would be presented with severe clinical symptoms but not in this outbreak where all affected trainees only presented with mild fever and rashes.

    Most prosthetic joint infections originate from wound contamination or haematogenous seeding from distant sites of infection. Bacteraemia may follow dental treatment but there is little evidence of it related to prosthetic joint infection. Nevertheless, controversy continues with regards to the effect of dental treatment in patients with prosthetic joints. This article reviews current English literature regarding the use of antibiotic prophylaxis in the dental management of patients with prosthetic joints. Routine antibiotic prophylaxis is not recommended for every patient with prosthetic joints when receiving dental treatments. However, antibiotic prophylaxis may be prescribed for high-risk groups with predisposing factors to infection when undergoing dental treatment with high risk of bacteraemia.

    Hepatitis A is a liver infection caused by the hepatitis A virus (HAV). Outbreaks of hepatitis A have been linked to the consumption of both raw and cooked shellfish. These outbreaks could induce a public confidence problem over shellfish safety and may result in important economic losses for the seafood industry. The work presented in this study investigated the presence of HAV in shellfish from Peninsular Malaysia. A total of 365 of cultured and wild shellfish from 36 sampling locations located throughout Peninsular Malaysia were examined using a commercial nucleic acid extraction and reverse transcription -polymerase chain reaction (RT-PCR) kit. HAV was not detected in almost all of the shellfish samples xamined. Only one cockle sample from Changkat, Seberang Perai was positive for HAV. The results suggest the absence of HAV or very low amount of HAV viral particles in most of the shellfish examined.

    Protein kinases (PKs) are regulators of protein phosphorylation in many infectious diseases, including malaria. How- ever, the cellular functions of majority of PKs in Plasmodium falciparum remain unknown. The mechanisms involved in P. falciparum cell cycle progress are not fully understood. The activation of cyclin-dependent kinases (CDKs), which constitute a PK family that includes crucial regulators of cell cycle progression in eukaryotes, is strictly being coordinated by the interaction with specific cyclins at well-defined points within the cell cycle. These cyclin/CDK complexes are very well characterised in humans, but little is known in P. falciparum. This review expand our un- derstanding of the characteristic of CDKs and cyclins in P. falciparum, and paves the way for further investigations on the precise molecular role of these crucial regulatory proteins in mosquito and human. This represents a valuable step towards the elucidation of cell cycle control mechanisms in malaria parasites.

    Chikungunya virus infection recently reemerged in Malaysia after 7 years of nondetection. Genomic sequences of recovered isolates were highly similar to those of Malaysian isolates from the 1998 outbreak. The reemergence of the infection is not part of the epidemics in other Indian Ocean countries but raises the possibility that chikungunya virus is endemic in Malaysia.

    Lymphatic filariasis is a parasitic infection that causes a devastating public health and socioeconomic burden with an estimated infection of over 120 million individuals worldwide. The infection is caused by three closely related nematode parasites, namely, Wuchereria bancrofti, Brugia malayi, and B. timori, which are transmitted to human through mosquitoes of Anopheles, Culex, and Aedes genera. The species have many ecological variants and are diversified in terms of their genetic fingerprint. The rapid spread of the disease and the genetic diversification cause the lymphatic filarial parasites to respond differently to diagnostic and therapeutic interventions. This in turn prompts the current challenge encountered in its management. Furthermore, most of the chemical medications used are characterized by adverse side effects. These complications urgently warrant intense prospecting on bio-chemicals that have potent efficacy against either the filarial worms or thier vector. In lieu of this, we presented a review on recent literature that reported the efficacy of filaricidal biochemicals and those employed as vector control agents. In addition, methods used for biochemical extraction, screening procedures, and structure of the bioactive compounds were also presented.

    Introduction: Tuberculosis is the second leading cause of death under the category of infectious diseases, after the human immunodeficiency virus (HIV). Tuberculous meningitis (TBM) constitutes about 5% of all extrapulmonary disease worldwide. This report describes a case of Tuberculous meningitis with rare presentation in a 28-year-old woman, who was treated based on a collection of her social background, clinical findings and Multiplex PCR of tuberculosis.

    Case presentation: A 28-year-old Malay woman with no significant medical history presented to HUSM with one month history of on and off fever, two weeks history of generalised limbs weakness and one week history of dysphagia. She was reported to have experienced visual hallucination and significant weight loss. Her laboratory result is significant for leukocytosis, elevated ESR and hypernatremia. Non-enhanced and contrast CT scan of the brain showed severe bilateral frontal cerebral atrophy. Cerebral spinal fluid (CSF) for multiplex PCR for Mycobacterium tuberculosis complex was positive. She was promptly started on anti-TB regime combined with dexamethasone. Subsequent follow-up showed significant improvement.

    Conclusion: This is a rare clinical manifestation of Tuberculous meningitis that demonstrates the importance of recognising and initiating the treatment early to reduce disabilities and improve clinical outcome.

    The organisation of the radiological services in Malaysia is described and those diseases in which radiology plays an important part in diagnosis are discussed. As radiology embraces all specialities a pattern of diseases emerges which is different from that seen in the West. The control of infectious diseases, the general improvement in health care and the more sophisticated radiological investigations now available mean that in future radiology will play a much more important part in diagnosis and management of patients.

    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: Pteropine orthoreovirus (PRV) is an emerging zoonotic respiratory virus that has spilled over from bats to humans. Though initially found only in bats, further case studies have found viable virus in ill patients.

    METHODOLOGY: PubMed was queried with the keywords of Nelson Bay orthoreovirus OR Pteropine orthoreovirus OR Melaka orthoreovirus OR Kampar orthoreovirus, and returned 17 hits.

    RESULTS: Based on prevalence studies, the presence of PRV has been reported in Malaysia and Vietnam, both developing countries. Other case reports also provide further evidence of the presence of PRV in the Southeast Asian region. Despite the absence of PRV in their home countries, travellers from Hong Kong and Japan to Indonesia have returned to their countries ill with this virus, indicating that local communities in Indonesia might be affected by this virus.

    CONCLUSIONS: This work aims to bring to light this emerging zoonotic respiratory virus circulating among developing countries in Southeast Asia. To improve the understanding of PRV of the medical and scientific community in the Southeast Asian region, this work introduces the general features of PRV, reports of imported PRV, prevalence, and clinical features of PRV. Gaps in knowledge about PRV have also been identified in this work, and we hope that future studies can be undertaken to improve our understanding of this virus.

    Men's health concerns have evolved from the traditional andrology and male sexual health to a more holistic approach that encompasses male psychological, social and physical health. The poor state of health in men compared to their female counterparts is well documented. A review of the epidemiological data from Malaysia noted a similar trend in which men die at higher rates in under 1 and above 15 years old groups and most disease categories compared to women. In Malaysia, the main causes of death in men are non-communicable diseases and injuries. Risk factors, such as risk-taking behaviour, smoking and hypertension, are prevalent and amenable to early interventions. Erectile dysfunction, premature ejaculation and prostate disorders are also prevalent. However, many of these morbidities go unreported and are not diagnosed early; therefore, opportunities for early intervention are missed. This reflects poor health knowledge and inadequate health-care utilisation among Malaysian men. Their health-seeking behaviour has been shown to be strongly influenced by family members and friends. However, more research is needed to identify men's unmet health-care needs and to develop optimal strategies for addressing them. Because the Malaysian population is aging and there is an increase in sedentary lifestyles, optimizing men's health will remain a challenge unless effective measures are implemented. The existing male-unfriendly health-care system and the negative influence of masculinity on men's health behaviour must be addressed. A national men's health policy based on a male-friendly approach to health-care delivery is urgently needed to provide a framework for addressing these challenges.

    Antibodies have been used efficiently for the treatment and diagnosis of many diseases. Recombinant antibody technology allows the generation of fully human antibodies. Phage display is the gold standard for the production of human antibodies in vitro. To generate monoclonal antibodies by phage display, the generation of antibody libraries is crucial. Antibody libraries are classified according to the source where the antibody gene sequences were obtained. The most useful library for infectious diseases is the immunized library. Immunized libraries would allow better and selective enrichment of antibodies against disease antigens. The antibodies generated from these libraries can be translated for both diagnostic and therapeutic applications. This review focuses on the generation of immunized antibody libraries and the potential applications of the antibodies derived from these libraries.

    Coronaviruses are known to cause fatal diseases like Severe Acute Respiratory Syndrome (SARS), Middle East Respiratory Syndrome (MERS) and recently recognised coronavirus disease 19 (COVID-19). It is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), a single-stranded RNA virus. This review is done to study the clinical presentation, comorbid conditions in COVID-19 patients. The relevant articles were searched in PubMed, Science direct and special issues in JAMA, and the New England Journal of Medicine. Only selected papers were used for data extraction and synthesis. The exact source of current pandemic of Covid-19 is not known. The main clinical symptoms include fever, dry cough, myalgia, dyspnoea. Other symptoms presented are headache, malaise, chills/rigor and diarrhoea. The mortality rate was high in above 60 years of age with the comorbid conditions. The data analysis revealed varied mortality rates in different regions. The mortality rate of COVID-19 has been highest among elderly individuals with the comorbid conditions.

    Despite being nearly 10 months into the COVID-19 (coronavirus disease 2019) pandemic, the definitive animal host for SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2), the causal agent of COVID-19, remains unknown. Unfortunately, similar problems exist for other betacoronaviruses, and no vouchered specimens exist to corroborate host species identification for most of these pathogens. This most basic information is critical to the full understanding and mitigation of emerging zoonotic diseases. To overcome this hurdle, we recommend that host-pathogen researchers adopt vouchering practices and collaborate with natural history collections to permanently archive microbiological samples and host specimens. Vouchered specimens and associated samples provide both repeatability and extension to host-pathogen studies, and using them mobilizes a large workforce (i.e., biodiversity scientists) to assist in pandemic preparedness. We review several well-known examples that successfully integrate host-pathogen research with natural history collections (e.g., yellow fever, hantaviruses, helminths). However, vouchering remains an underutilized practice in such studies. Using an online survey, we assessed vouchering practices used by microbiologists (e.g., bacteriologists, parasitologists, virologists) in host-pathogen research. A much greater number of respondents permanently archive microbiological samples than archive host specimens, and less than half of respondents voucher host specimens from which microbiological samples were lethally collected. To foster collaborations between microbiologists and natural history collections, we provide recommendations for integrating vouchering techniques and archiving of microbiological samples into host-pathogen studies. This integrative approach exemplifies the premise underlying One Health initiatives, providing critical infrastructure for addressing related issues ranging from public health to global climate change and the biodiversity crisis.
