    OBJECTIVE: To disseminate the portable sequencer MinION in developing countries for the main purpose of battling infectious diseases, we found a consortium called Global Research Alliance in Infectious Diseases (GRAID). By holding and inviting researchers both from developed and developing countries, we aim to train the participants with MinION's operations and foster a collaboration in infectious diseases researches. As a real-life example in which resources are limited, we describe here a result from a training course, a metagenomics analysis from two blood samples collected from a routine cattle surveillance in Kulan Progo District, Yogyakarta Province, Indonesia in 2019.

    RESULTS: One of the samples was successfully sequenced with enough sequencing yield for further analysis. After depleting the reads mapped to host DNA, the remaining reads were shown to map to Theileria orientalis using BLAST and OneCodex. Although the reads were also mapped to Clostridium botulinum, those were found to be artifacts derived from the cow genome. An effort to construct a consensus sequence was successful using a reference-based approach with Pomoxis. Hence, we concluded that the asymptomatic cow might be infected with T. orientalis and showed the usefulness of sequencing technology, specifically the MinION platform, in a developing country.

    Background: The COMBI concept is a novel approach by the WHO to control communicable diseases which are influenced by community behaviour. The Ministry of Health is currently evaluating its use against dengue in selected areas throughout Malaysia. COMBI doctrine differs from previous dengue campaigns. It acknowledges that the factors contributing to dengue proliferation may differ between areas. Factors for a given area are analysed, then a single precise behavioural goal to overcome those problems is formulated. To inculcate this behavioural change, the target community is subjected to an intensive campaign using Integrated Marketing Communication techniques adapted from the advertisingindustry, particularly involving volunteers from the community itself.
    Methodology: In Selangor the pilot project was implemented in Section 3 and Section 4 of Bandar Baru Bangi, in the district of Hulu Langat. Here, Aedes breeding was found to occur mainly in water containers of semi permanent nature (eg. ‘kolah’, aquatic plant jars, flower pot bases etc). A total of 172 volunteers were recruited to disperse the message of “Suluh – Suluh, Basuh - Basuh” whilst distributing leaflets and flashlights to 2666 homes. Residents were instructed to illuminate such water containers twice weekly and scrub any containers found to contain larvae. The program commenced on 23/5/2004 and lasted 16 weeks.
    Results : During this period, the initial Aedes Index of 5 was reduced to 0.96 while combined cases of Dengue Fever / Dengue Haemorraghic Fever in Sections 3 and 4 reported to the Hulu Langat District Health Office also dropped to 1 (unconfirmed).
    Conclusion : The COMBI approach in Hulu Langat successfully demonstrated that correct problem identification synergized with community engagement can potentially reduce Aedes proliferationand dengue morbidity.

    Military personnel who are deployed for peace-keeping missions are exposed to many hazards, including infectious diseases. One of the most common and fatal infectious disease is Malaria. Although well controlled in Malaysia, this deadly disease is still widely endemic in many other countries especially Africa. We would like to report the case of a military personnel who was infected with Malaria during a peace-keeping mission in Sudan and subsequently died after returning home. We hope that by reporting this case in depth, strategic actions can be taken to avoid similar unfortunate events in future.

    Chikungunya virus (CHIKV) is an alphavirus of the Togaviridae family that causes chronic and incapacitating arthralgia in human populations. Since its discovery in 1952, CHIKV was responsible for sporadic and infrequent outbreaks. However, since 2005, global Chikungunya outbreaks have occurred, inducing some fatalities and associated with severe and chronic morbidity. Chikungunya is thus considered as an important re-emerging public health problem in both tropical and temperate countries, where the distribution of the Aedes mosquito vectors continues to expand. This review highlights the most recent advances in our knowledge and understanding of the epidemiology, biology, treatment and vaccination strategies of CHIKV.

    Protein-protein interactions (PPIs) are essential for understanding cell physiology in normal and pathological conditions, as they might involve in all cellular processes. PPIs have been widely used to elucidate the pathobiology of human and plant diseases. Therefore, they can also be used to unveil the pathobiology of infectious diseases in shrimp, which is one of the high-risk factors influencing the success or failure of shrimp production. PPI network analysis, specifically host-pathogen PPI (HP-PPI), provides insights into the molecular interactions between the shrimp and pathogens. This review quantitatively analyzed the research trends within this field through bibliometric analysis using specific keywords, countries, authors, organizations, journals, and documents. This analysis has screened 206 records from the Scopus database for determining eligibility, resulting in 179 papers that were retrieved for bibliometric analysis. The analysis revealed that China and Thailand were the driving forces behind this specific field of research and frequently collaborated with the United States. Aquaculture and Diseases of Aquatic Organisms were the prominent sources for publications in this field. The main keywords identified included "white spot syndrome virus," "WSSV," and "shrimp." We discovered that studies on HP-PPI are currently quite scarce. As a result, we further discussed the significance of HP-PPI by highlighting various approaches that have been previously adopted. These findings not only emphasize the importance of HP-PPI but also pave the way for future researchers to explore the pathogenesis of infectious diseases in shrimp. By doing so, preventative measures and enhanced treatment strategies can be identified.

    Orbital cellulits is one of the life threatening event that should not be missed out and must be distinguished from preseptal cellulitis. It is an infective process involving ocular adnexal structures posterior to the orbital septum. High index of suspicion is the key to its diagnosis as even experienced physician can miss. Here, we present a case of a 15-year-old female who presented with progressive swelling over right forehead associated with high grade fever, headache and purulent discharge of the swelling. She was diagnosed with sepsis due to right forehead abscess and was treated with intravenous antibiotics followed with admission. However, she suddenly deteriorated in the ward which required intubation and thereby Intensive Care Unit (ICU) admission. Investigations revealed fluid collection at right retrobulbar space suggestive of an abscess where emergency drainage was carried out. Unfortunately, her condition worsened and patient succumbed at day-10 of admission, despite all efforts.

    In this manuscript, we investigate a nonlinear delayed model to study the dynamics of human-immunodeficiency-virus in the population. For analysis, we find the equilibria of a susceptible-infectious-immune system with a delay term. The well-established tools such as the Routh-Hurwitz criterion, Volterra-Lyapunov function, and Lasalle invariance principle are presented to investigate the stability of the model. The reproduction number and sensitivity of parameters are investigated. If the delay tactics are decreased, then the disease is endemic. On the other hand, if the delay tactics are increased then the disease is controlled in the population. The effect of the delay tactics with subpopulations is investigated. More precisely, all parameters are dependent on delay terms. In the end, to give the strength to a theoretical analysis of the model, a computer simulation is presented.

    In an aim of developing portable biosensor for SARS-CoV-2 pandemic, which facilitates the point-of-care aptasensing, a strategy using 10 μm gap-sized gold interdigitated electrode (AuIDE) is presented. The silane-modified AuIDE surface was deposited with ∼20 nm diamond and enhanced the detection of SARS-CoV-2 nucleocapsid protein (NCP). The characteristics of chemically modified diamond were evidenced by structural analyses, revealing the cubic crystalline nature at (220) and (111) planes as observed by XRD. XPS analysis denotes a strong interaction of carbon element, composed ∼95% as seen in EDS analysis. The C-C, CC, CO, CN functional groups were well-refuted from XPS spectra of carbon and oxygen elements in diamond. The interrelation between elements through FTIR analysis indicates major intrinsic bondings at 2687-2031 cm-1. The aptasensing was evaluated through electrochemical impedance spectroscopy measurements, using NCP spiked human serum. With a good selectivity the lower detection limit was evidenced as 0.389 fM, at a linear detection range from 1 fM to 100 pM. The stability, and reusability of the aptasensor were demonstrated, showing ∼30% and ∼33% loss of active state, respectively, after ∼11 days. The detection of NCP was evaluated by comparing anti-NCP aptamer and antibody as the bioprobes. The determination coefficients of R2 = 0.9759 and R2 = 0.9772 were obtained for aptamer- and antibody-based sensing, respectively. Moreover, the genuine interaction of NCP aptamer and protein was validated by enzyme linked apta-sorbent assay. The aptasensing strategy proposed with AuIDE/diamond enhanced sensing platform is highly recommended for early diagnosis of SARS-CoV-2 infection.

    Two active interventions were carried out in order to encourage breast feeding of low birth weight (LBW) neonates who were admitted to the neonatal intensive care unit (NICU), Universiti Sains Malaysia. These were the establishment of (a) an effective transport system for conveying expressed breast milk (EBM) from the motherk home to the neonatal intensive care unit and (b) providing rooming-infacilities in the neonatal ward. The EBM was transported by a male health assistant, by the parents themselves or by the local bus company. A total of 473 babies were admitted from April 1994 to September 1995. Thirty-three babies weighed between 540-1000g and 440 were between 1001-2000g. A total of 226 (47.8%) babies were given mixed formula (less than 20% of daily needs) and EBM feeds (Group A) and 247 (52.2%) were given only formula feeds (Group B). A total of 79 babies died of which 5 were in Group A and 74 were in group B. (P value is 0.00). In Group A, 45 babies had clinical sepsis, 9 of whom were blood culture positive. Four of these babies died. In group B, out of 108 babies with clinical sepsis 36 were blood culture positive. 29 died because of the sepsis This study shows that by providing an effective transport system for breast milk expressed at home and the availability of roomingfacilities in the neonatal ward a significant number of LBW babies admitted to the NICU continue to receive their mothers' milk. The incidence of nosocomial sepsis and the over all mortality due to sepsis was significantly higher in those on full formulafeeding compared to those given mixed formula and expressed breast milk.

    OBJECTIVE: Tropical neuroinfections are still cause of substantial mortality in travelers. Therefore, good knowledge of early symptoms is very important for nurses acting as first contact persons.

    METHODS: Nurse's practical skills and knowledge of signs and early recognition of tropical neuroinfections, providing first aid and quick action has been studied among graduates of two Tropical Nursing PhD programs (in EU-Countries vs. tropical country) using a standardized questionnaire. Statistical package EPI info was used to determine potential differences between both groups of graduates.

    RESULTS: Acceptable knowledge on early symptoms and signs of cerebral malaria and meningococcal meningitis in returning travelers was found among 121 graduates of two PhD programs who were included in the study. Of these, 99 questionnaires were filled in Slovakia, Czech Republic and Germany and another 22 were filled in Malaysia, as a part of the Tropical Nursing PhD Study Programs.

    CONCLUSION: Nursing students and recent graduates in two PhD programs demonstrated acceptable, although not large-scaled, knowledge of early signs and symptoms of tropical neuroinfections.

    Infectious diseases account for a third of all the deaths in the developing world. Achievements in understanding the basic microbiology, pathogenesis, host defenses and expanded epidemiology of infectious diseases have resulted in better management and reduced mortality. However, an emerging infectious disease, melioidosis, is becoming endemic in the tropical regions of the world and is spreading to non-endemic areas. This article highlights the current understanding of melioidosis including advances in diagnosis, treatment and prevention. Better understanding of melioidosis is essential, as it is life-threatening and if untreated, patients can succumb to it. Our sources include a literature review, information from international consensus meetings on melioidosis and ongoing discussions within the medical and scientific community.

    This paper sheds light on infectious diseases and the status of malnutrition in Nepal, a Himalayan country located in South Asia. In spite of efforts by both Government and non-government sectors, infectious diseases are rampant in the countries constituting a major cause of morbidity and mortality, which in turn, impose a socio-economic and public health burden for the country. Intestinal parasitic infection has been implicated in the causation of malnutrition. Malnutrition associated with child mortality is more common among children aged less than five years. Nepalese women suffer from chronic malnutrition. People in rural areas are more affected by malnutrition than those in urban areas. This has been attributed to poverty, lack of education, and rampant infectious diseases.

    •IoT within infectious disease epidemiology is an emerging field of research, however the ubiquitous availability of smart technologies, as well as increased risks of infectious disease spread through the globalization and interconnectedness of the world necessitates its use for predicting, preventing and controlling emerging infectious diseases.•Considering the present situation in China, IoT based smart disease surveillance systems have the potential to be a major breakthrough in efforts to control the current pandemic. With much of the infrastructure itself in place already (i.e. smartphones, wearable technologies, internet access) the role this technology can have in limiting the spread of the pandemic involves only the collection and analysis of data already gathered.•More research must be carried out for the development of automated and effective alert systems to provide early and timely detection of outbreaks of such diseases in order to reduce morbidity mortality and prevent global spread.

    Malaria and dengue fever are among the most common mosquito-borne diseases worldwide; however, reports of coinfection are rare. We present a case of severe malaria and dengue coinfection in a 16-yearold female patient presenting with fever, thrombocytopenia, pleural effusion, myopericarditis, and acute respiratory distress syndrome. Dengue infection was confirmed by the presence of immunoglobin M antibodies and nonstructural protein 1, while malaria was confirmed by the presence of Plasmodium vivax in thick and thin blood smears. This is the first report of a dengue/malaria coinfection in Mexico.

    Emerging zoonoses threaten global health, yet the processes by which they emerge are complex and poorly understood. Nipah virus (NiV) is an important threat owing to its broad host and geographical range, high case fatality, potential for human-to-human transmission and lack of effective prevention or therapies. Here, we investigate the origin of the first identified outbreak of NiV encephalitis in Malaysia and Singapore. We analyse data on livestock production from the index site (a commercial pig farm in Malaysia) prior to and during the outbreak, on Malaysian agricultural production, and from surveys of NiV's wildlife reservoir (flying foxes). Our analyses suggest that repeated introduction of NiV from wildlife changed infection dynamics in pigs. Initial viral introduction produced an explosive epizootic that drove itself to extinction but primed the population for enzootic persistence upon reintroduction of the virus. The resultant within-farm persistence permitted regional spread and increased the number of human infections. This study refutes an earlier hypothesis that anomalous El Niño Southern Oscillation-related climatic conditions drove emergence and suggests that priming for persistence drove the emergence of a novel zoonotic pathogen. Thus, we provide empirical evidence for a causative mechanism previously proposed as a precursor to widespread infection with H5N1 avian influenza and other emerging pathogens.

    Challenges arising from epidemic infectious disease outbreaks can be more effectively met if traditional public health is enhanced by sociology. The focus is normally on biomedical aspects, the surveillance and sentinel systems for infectious diseases, and what needs to be done to bring outbreaks under control quickly. Social factors associated with infectious disease outbreaks are often neglected and the aftermath is ignored. These factors can affect outbreak severity, its rate and extent of spread, influencing the welfare of victims, their families, and their communities. We propose an agenda for research to meet the challenges of infectious disease outbreaks. What social factors led to the outbreak? What social factors affected its severity and rate and extent of spread? How did individuals, social groups, and the state react to it? What are the short- and long-term effects on individuals, social groups, and the larger society? What programs can be put in place to help victims, their families, and affected communities to cope with the consequences--impaired mental and physical health, economic losses, and disrupted communities? Although current research on infectious disease outbreaks pays attention to social factors related to causation, severity, rate and extent of spread, those dealing with the "social chaos" arising from outbreaks are usually neglected. Inclusion, by combining traditional public health with sociological analysis, will enrich public health theory and understanding of infectious disease outbreaks. Our approach will help develop better programs to combat outbreaks and equally important, to help survivors, their families, and their communities cope better with the aftermath.
