Social distancing is impossible for most Indians. More than 500 million people live in densely populated slums, urban villages or makeshift housing; large families share small spaces; many don’t have direct access to running water or basic sanitation. Most had not heard of hand sanitiser until three weeks ago. The Indian government’s response to Covid-19 has not, so far, accounted for the lives of the majority of India’s population, or the informal nature of much of the economy. Attempts to control the virus have instead exacerbated a vicious form of social distancing that has marginalised this same population for centuries: the caste system.
