The ICMR conducted its fourth national serology survey to test for Chinese coronavirus antibodies from June 14 through July 6. The state health body analyzed blood samples from a total of 36,227 people — including 28,975 adults and children and 7,252 healthcare workers — in 70 districts across 21 Indian states. ICMR based its latest analysis on the same geographic locations used for its previous three rounds of serology surveys.
