July 28, 2020

The Ministry of Health declared the results of a serological survey carried out in Delhi between June 27 and July 10, which showed that 22.86% of the people surveyed had developed IgG antibodies, indicating they had been exposed to the novel coronavirus that causes Covid-19.

About:

A serological survey seeks to assess the prevalence of disease in a population by detecting the presence of specific antibodies against the virus.
A serological test is performed to diagnose infections and autoimmune illnesses. It can also be conducted to check if a person has developed immunity to certain diseases.
The test indicates past infections (and which triggered an immune response), and is not used to detect active infections.
