TIRUNELVELI Following the door-to-door check to identify the COVID-19 patients at the early stage that has given excellent results in bringing down the number of fresh cases in the district, the district administration has deployed a Village Health Nurse for every 100 houses to visit the residents every day and check their health parameters in a bid to further fine-tune the early detection. According to Collector V. Vishnu, the recently introduced screening of residents at their doorsteps by the health workers for COVID-19 ensured the early detection of the persons who had contracted the viral infection and remain asymptomatic. Since the visiting health workers lifted samples from the COVID-19 suspects, who were still unaware of their infection, they were sent to the triaging centre for further investigations and appropriate treatment, which drastically curtailed the number of fresh cases and the early intervention averted deaths.
