Slums in India are characterized by overcrowded homes and lack of access to such basic services as water and sanitation. Slum population estimates for India range from 65.5 million to 121 million people. General preventive measures in India such as lockdowns, home quarantine, frequent hand washing, etc will not work for slums due to their high population densities, inadequate services and preexisting conditions. Public health measures that work in slum contexts need to be thought of. In addition, cities need to improve living conditions for urban poor that reside in slums to make these habitats worth living in.
