A sero survey conducted at a leading hospital here over five months has found that the prevalence of antibodies, in a person who has recovered from coronavirus infection, persists for 60-80 days. The survey found that antibodies persisted in the recovered patient's body for at least 60 days, depending on when the participant was infected or came in touch with infected people. The participants of the sero survey, jointly done by the Max Hospital and Institute of Genomics and Integrative Biology, under the Council for Scientific and Industrial Research (CSIR), will again be tested to assess how long the anti-bodies last in the person who contracted COVID-19, said Shantanu Sengupta, the IGIB scientist who conducted the study.
A total of 780 samples were used for the serological testing which include hospital workers and individuals who visited the hospital during the pandemic. "Our study results confirm that anti SARS-CoV-2 antibodies could remain for more than 60 days in the body. This is a step forward towards better understanding of the infection recovery and re-infection pattern. There is a need for larger follow-up studies to further assess how long the antibodies remain stabilised in the body," Sengupta said.
