Unaccounted deaths or exceptional management of epidemic: what we can see from latest seroprevalence survey
4th round of seroprevalence survey by ICMR in June-July 2021 has revealed that nearly 2/3rd of Indian population has antibodies. The presence of antibodies is assumed to indicate prior exposure (though not necessarily manifested with disease symptoms) to Coronavirus. Exposure to virus can be seen as indicative of low probability of Covid-19, at least for the short-term. Very high seropositivity, more than 70%, suggests low probability of occurrence of severe Covid-19 outbreak. Table 1 After feeling somewhat relived over national estimate, if we look at state-level results, there is a variation of seropositivity levels. (Table 1) Seropositivity is highest in Madhya Pradesh (79%) and least in Kerala (44.4%). It has been noted with hint of surprise that Kerala and Maharashtra do not have very high seropositivity despite bagging the attention for their high Covid-19 numbers for sustained duration. We must understand that one should read these state level numbers with some ...
