Health Desk-Oct 13, 2020: Around 45 percent of the people, covered by a survey in the capital, were found to be carrying Covid-19 antibody, according to a study by the Institute of Epidemiology, Disease Control and Research.
The presence of such antibody among slum dwellers was much higher -- about 74 percent, mentions the study based on data collected between April 18 and July 5 this year.
A total of 3,227 households across the capital were surveyed under the study jointly conducted by the IEDCR and the International Centre for Diarrhoeal Disease Research, Bangladesh (icddr,b).
The Bill and Melinda Gates Foundation and the USAID supported the first-ever cross-sectional epidemiological survey in Bangladesh. A summary of the survey was published on August 10.
