The survey was conducted by IISER along with Savitribai Phule Pune University (SPPU), Translational Health Science and Technology Institute (THSTI), Faridabad and Pune Municipal Corporation (PMC). Persistent Foundation provided funding of Rs 75 lakh for this and future surveys to be conducted in the city.

The findings of this survey were announced by Pune Divisional Commissioner Saurabh Rao, IISER's Prof Shashidhar and Prof Arnab Ghosh and SPPU's Prof Arti Agarkar in a press conference on Monday evening.

Dr Ghosh said, "There are deep implications of these findings on the clinical management of COVID-19 in the city. 51 per cent seroprevalence does not mean that those persons in whom the antibodies were found will be protected from the coronavirus infection in the future.

Prof Shashidhar said, "We still do not have a clear picture of how many people are affected by COVID-19 in the city. The number of COVID-19 positive patients in Pune is still high and there is a strong possibility of a second wave in the city."
Rao said, "One positive finding from this survey has been that prevalence in senior citizens is very less as compared to others and that is a relief for us."
