Statistical principles in the design of serosurveys View Presentation

Infections were near a peak in Karnataka during September 2020 when a state wide COVID-19 serosurvey was conducted. For accurate total disease-burden estimation during such periods, both the active infection and the seroprevalence of antibodies to the virus must be estimated. This requires the use of multiple tests, e.g., antigen and RT-PCR tests for active infection estimation, and serology for antibody prevalence estimation. We will discuss the challenges in combining data from multiple tests, the science of optimal design, what ought to have been the design, and how this optimal design was used in the second survey in January-February 2021.<br /><br /> The talk will be based on joint work with collaborators from the Indian Institute of Public Health, Indian Statistical Institute, Strand Life Sciences, and the Indian Institute of Science.
