In the scorching heat, armed with a mask to be washed and reused every day, 38-year-old Shantamma (name changed) has been walking for the last two hours, visiting homes and tracking their health records. An Accredited Social Health Activist (ASHA), she is now on her way to check on a family in quarantine in Kerala's Thiruvananthapuram. She has five such families now to closely monitor, among the usual 700 homes under her surveillance.
