Responding to the Potential of Ebola Virus Disease (EVD) Importation into Malaysia.

The current Ebola outbreak, which is the first to affect West African countries, has been declared to have met the conditions for a Public Health Emergency of International Concern (PHEIC) by the World Health Organization (WHO). Thus, the Ministry of Health (MOH) of Malaysia has taken steps to strengthen and enhanced the five core components of preparedness and response to mitigate the outbreak. The National Crisis Preparedness and Response Centre (CPRC) commands, controls and coordinates the preparedness and response plans for disasters, outbreaks, crises and emergencies (DOCE) related to health in a centralised way. Through standardised case definition and mandatory notification of Ebola by public and private practitioners, surveillance of Ebola is made possible. Government hospitals and laboratories have been identified to manage and diagnose Ebola virus infections, and medical staff members have been trained to handle an Ebola outbreak, with emphasis on strict infection prevention and control practices. Monitoring of the points of entry, focusing on travellers and students visiting or coming from West African countries is made possible by interagency collaborations. To alleviate the public's anxiety, effective risk communications are being delivered through various channels. With experience in past outbreak control, the MOH's preparedness and response plans are in place to abate an Ebola outbreak.

Cross-sectional study of influenza trends and costs in Malaysia between 2016 and 2018.

BACKGROUND AND OBJECTIVES: While influenza circulates year-round in Malaysia, research data on its incidence is scarce. Yet, this information is vital to the improvement of public health through evidence-based policies. In this cross-sectional study, we aimed to determine the trends and financial costs of influenza. METHODS: Data for the years 2016 through 2018 were gathered retrospectively from several sources. These were existing Ministry of Health (MOH) influenza sentinel sites data, two teaching hospitals, and two private medical institutions in the Klang Valley, Malaysia. Expert consensus determined the final estimates of burden for laboratory-confirmed influenza-like illness (ILI) and severe acute respiratory infection (SARI). Economic burden was estimated separately using secondary data supplemented by MOH casemix costing. RESULTS: Altogether, data for 11,652 cases of ILI and 5,764 cases of SARI were extracted. The influenza B subtype was found to be predominant in 2016, while influenza A was more prevalent in 2017 and 2018. The distribution timeline revealed that the highest frequency of cases occurred in March and April of all three years. The costs of influenza amounted to MYR 310.9 million over the full three-year period. CONCLUSIONS: The study provides valuable insights into the dynamic landscape of influenza in Malaysia. The findings reveal a consistent year-round presence of influenza with irregular seasonal peaks, including a notable influenza A epidemic in 2017 and consistent surges in influenza B incidence during March across three years. These findings underscore the significance of continuous monitoring influenza subtypes for informed healthcare strategies as well as advocate for the integration of influenza vaccination into Malaysia's national immunization program, enhancing overall pandemic preparedness.

COVID-19 in Malaysia: Descriptive Epidemiologic Characteristics of the First Wave.

This study aimed to describe the characteristics of COVID-19 cases and close contacts during the first wave of COVID-19 in Malaysia (23 January 2020 to 26 February 2020), and to analyse the reasons why the outbreak did not continue to spread and lessons that can be learnt from this experience. Characteristics of the cases and close contacts, spatial spread, epidemiological link, and timeline of the cases were examined. An extended SEIR model was developed using several parameters such as the average number of contacts per day per case, the proportion of close contact traced per day and the mean daily rate at which infectious cases are isolated to determine the basic reproduction number (R0) and trajectory of cases. During the first wave, a total of 22 cases with 368 close contacts were traced, identified, tested, quarantine and isolated. Due to the effective and robust outbreak control measures put in place such as early case detection, active screening, extensive contact tracing, testing and prompt isolation/quarantine, the outbreak was successfully contained and controlled. The SEIR model estimated the R0 at 0.9 which further supports the decreasing disease dynamics and early termination of the outbreak. As a result, there was a 11-day gap (free of cases) between the first and second wave which indicates that the first wave was not linked to the second wave.
