Here is a simple idea to maintain social distancing--ask people to take an umbrella when they go out. This Eureka moment came to Dr Kutikuppala Suryarao when he and his colleagues went to Raitu Bazaar in Visakhapatnam and asked people crowding there if they had heard of social distancing. About 85% of them said no. The rest said they had heard of it but didn't know how to maintain it.
