I am new here. Also, right now Indian weather is very hot (40-46 C or 104-116F). Indian covid-19 cases is unusually low for such a crowded country. Despite every expert insisting there might be link between high temp and covid-19 spread, Indian government has done no testing or research. We are used to very high temperatures ( the reason why we have darker skin ), (any) flu is never a huge issue in India. I would say Herd Immunity is a better idea than Herd mentality !
