This study covers the two southern states of Tamilnadu and Andhra Pradesh with total population of 128 million. Contact tracers in the 2 states reached about 3 million contacts for the 435,000 coronavirus cases. Researchers analyzed data from 85000 of these cases where enough data was available with 600,000 contacts. Some interesting findings are-

About 5300 children infected 2500 contacts among other school age children showing children in schools can spread the virus.
