As per antibody testing 0.33% may got covid in Kerala and .76 % in India,,,so whole India 20 times more may be have got covid than clinically confirmed one ..which is some what hiegher than international anitibody testing in other countries ..USA and Europe showed 10 times higher actual cases as per anitibody testing...Kerala have upto 35 times actual case as per study ,,which is possible with extremely low level of testing in Kerala,...most of whatever test done in Kerala is either for those doing surgery or tests for those already in treatment to make them negative ..ideally no other place do that now..
