Sero-surveillance of COVID-19 among slum and non-slum dwellers in Dhaka and Chattogram Cities and the impact of pandemic on mental health status

Narrative Description of Project  


The common notion among the Bangladeshi slum dwellers is that they are safe from COVID-19 and that the disease only affects the affluent members of the society. Globally there are no indications that individuals with certain characteristics are not susceptible to SARS-CoV-2 infections. According to recent news reports from India, the sero-prevalence rate in the slums was 23% in Delhi and 57% in Mumbai, while in residential households it was 16%. Recent population-based survey on COVID-19 prevalence in 720 households in Bangladeshi slums indicated that only ~6% population were infected, while overall nationwide surveillance showed 9% prevalence. Surprisingly among the infected slums dwellers, about 80% were asymptomatic.

The main objective of the survey is to assess the Sero-surveillance of COVID-19 among slum and non-slum dwellers in Dhaka and Chattogram Cities and the impact of pandemic on mental health status.
