Epidemiology, clinical characteristics, and genetic diversity of Nipah virus strains from Bangladesh: 2016-2023.

Objectives: Nipah virus (NiV) causes deadly outbreaks in Bangladesh, with a fatality rate of 71%. Two sublineages, NiV-BD 1 and NiV-BD 2, have been identified. This study aimed to characterize their epidemiologic and clinical diversity.

Detection of Nipah Virus in Human Milk: A Novel Finding.

Nipah virus (NiV) causes severe diseases in humans with a high case fatality rate. The primary risk factors for NiV infection in Bangladesh are drinking raw date palm sap (DPS) contaminated with Pteropus fruit bat secretions/excretions or close contact with or exposure to the body fluid of an individual with NiV infection. During the 2023 NiV outbreak investigation in Bangladesh, the breast milk of a NiV-infected nursing mother was tested by real-time reverse transcriptase polymerase chain reaction (RT-PCR) for detection of NiV-RNA.

COVID-19 Risk Perception and Prevention Practices among High- and Low-Density Populations in Bangladesh: A Mixed-Methods Study.

We aimed to explore coronavirus disease 2019 (COVID-19) risk perception and prevention practices among people living in high- and low-population density areas in Dhaka, Bangladesh. A total of 623 patients with confirmed COVID-19 agreed to participate in the survey. Additionally, we purposively selected 14 participants from diverse economic and occupational groups and conducted qualitative interviews for them accordingly.

Prevalence of COVID-19 in Bangladesh, April to October 2020-a cross-sectional study.

The aim of this study was to estimate the proportion of symptomatic and asymptomatic laboratory-confirmed coronavirus disease 2019 (COVID-19) cases among the population of Bangladesh. A cross-sectional survey was conducted in Dhaka City and other districts of Bangladesh between April 18 and October 12, 2020. A total of 32 districts outside Dhaka were randomly selected, and one village and one mahalla was selected from each district; 25 mahallas were selected from Dhaka City.

Transmission of SARS-CoV-2 in the Population Living in High- and Low-Density Gradient Areas in Dhaka, Bangladesh.

Community transmission of SARS-CoV-2 in densely populated countries has been a topic of concern from the beginning of the pandemic. Evidence of community transmission of SARS-CoV-2 according to population density gradient and socio-economic status (SES) is limited. In June−September 2020, we conducted a descriptive longitudinal study to determine the community transmission of SARS-CoV-2 in high- and low-density areas in Dhaka city.
