‘More than corona, fear is the real killer,’ says an affected family in Andhra Updated: Updated: Share Article AAA CHITTOOR After some class X students tested positive for Covid-19 on April 29, Ravi Kumar (41), a biology teacher at the municipal high school at Nagari, crippled in both legs due to polio, was gripped with fear, as he had taught them in close proximity. A resident of Narayanavanam, 20 km from Nagari, the teacher would keep shuttling between school and home on his tri-scooter. The fact that three of his colleagues had succumbed to the dreaded virus recently, preceded by a number of casualties among the teachers elsewhere in Chittoor district since the Covid first wave, was enough to whip up his worst fears, making him tremble and swoon often.
