Contact Tracing Limits COVID-19 Cases in Northern Indian State Anjana Pasricha NEW DELHI - When COVID-19 cases started surfacing in India in March, India's northern state of Himachal Pradesh went into a stringent lockdown as soon as it identified its first two cases. Worries were high because picturesque towns in the state, nestled along Himalayan slopes, receive many domestic and foreign tourists -- India's initial infections came through overseas travelers. The state took on the challenge of controlling the infection by putting in place a system of contact tracing involving tracking and testing anyone who had been in contact with an infected person to help break the chain of transmission. "As soon as we get a positive, within an hour or half an hour we are able to trace the entire contacts using digital technology, and the very next day we get them tested," said Rakesh Prajapati, the district collector in Kangra, the state's largest district.
