New Delhi: A fresh sero-prevalence survey in the national capital began on Saturday for a comprehensive assessment of the COVID-19 situation, but due to the Eid holiday not many samples could be collected, officials said.

Hence, it has been decided to extend the survey till August 7, a senior official said.

Originally, the survey was supposed to be a five-day exercise from August 1-5.


It began with samples being collected from four districts, including North Delhi and Northwest Delhi, on Saturday, and will span all districts and cover various demographic segments.

A senior government official said not many samples could be collected on Saturday since it was a festival day. So, the survey has been extended by two days till August 7.

Delhi Health Minister Satyendar Jain told reporters the previous survey had indicated that about 24 per cent of the people whose samples were taken had shown presence of antibodies, meaning they had got infected and recovered.
