India inching towards herd immunity, 1 in 4 people already infected by COVID, says Dr Velumani

Most parts of India may be inching towards acquiring “involuntary” herd immunity against COVID-19, according to a seroprevalence study done by Thyrocare Technologies Ltd, a leading diagnostic and testing company.

The study suggests that about one out of four individuals have already been infected by the novel coronavirus.

Speaking to The Federal for a podcast, Dr. A. Velumani, a biotechnologist and founder-chairperson of Thyrocare, said that after just 15 days of testing, their company understood that the country had a positivity rate of 15%, which was “a pleasant surprise”. He added that the positivity rate currently stood at 26%.
