Number of cases depend on testing .. let compare india with usa which is worat affected ..even reporting death also different.. .let compare new york with new Delhi ...as per serological antibody testing at least 25 % delhi got covI'd ..but only a fraction is reported as testing is very low..while as per serological test only 18 % got covid in new York...even in kerala when antibody testing done level of infection was 50 times hiegher than what reported and govt rejected test results ..
If compare with other coutries there lot of coutries with very low infection rate and pandemic in full control .
