The past week has seen a major sanitisation exercise in Bharkhula, a village of 2,500 people in west Uttar Pradesh's Aligarh, after a major coronavirus scare where eight members of one family tested positive in the last 10 days. All but one of them is in home isolation. "It started with one boy. He used to work in a bank. He used to help people withdraw money. During the lockdown, he must have helped 200 people withdraw money. He was a bank sewak and must have been exposed to a coronavirus positive person," said Basudev Singh, the village chief.
