From their Chennai home, sisters Grace and Preethi - both Covid survivors - virtually help positive patients and their families every day with verified information on the availability of beds, oxygen, ambulance, medicine and even food. They share the information on their Instagram pages and work eighteen hours a day. They helped save hundreds of lives when the second wave of the pandemic peaked in the country. The sisters lost their maternal grandparents to Covid after five members of their family contracted the virus. Now, they are helping others by providing key leads they had struggled to find.
