The results of the second serosurvey, which was conducted in Chennai recently to detect the transmission of coronavirus, have revealed that nearly one-third of the city’s population has been exposed to the pathogen. The results have shown an overall positivity rate of 32.3 percent, authorities said.

This was more than the number of those found affected by the virus during the first survey conducted in July.

“Results of Chennai Serosurvey-II: Serosurvey samples tested- 6,389 out of which 2,062 are positive for IgG antibodies presence with overall positivity of 32.3 percent,” Greater Chennai Corporation said in a brief statement.

The first phase of the survey, with a sample size of around 12,000, had revealed (on September 1) that a fifth of the population (21.5 percent) in the metropolis had exposure to the pathogen.
