AMC Riverfront office: Amdavad Municipal Corporation (AMC) today said it conducted second survey related to Covid-19 infection, covering 10,000 persons. While the earlier survey showed 17.61 per cent positivity, the latest survey shows 23.24 per cent positivity. It means there’s 5.5 per cent increase in positivity over one and half month period. This indicates that there’s no herd immunity as of now prevalent in the city because herd immunity would require 70 to 80 percent positivity.

The AMC also did another survey to check antibody among them who had earlier infected with Covid-19 and recovered. In 40 per cent of those surveyed, antibody had disappeared. It shows that after infected with Covid-19 and recovered from the same, anti body doesn’t sustain for long. Around 40 per cent persons had no anti body left which suggest that they may have Covid infection again. However more study is required on this.

These details were shared by Dr. Bhavin Solank, Medical Officer of Health, AMC today. DeshGujarat
