Dharavi: Asia's biggest slum may have reached 'herd immunity' unknowingly
A serological survery has revealed that six out of ten people from Asia's biggest slum, Dharavi, can be identified as antibodies for the novel coronavirus. The findings were revealed in a serological survey conducted in July from 6,936 people across three suburbs in Mumbai, India. The survey reveals that more than half of the population has suffered and recovered from COVID-19. This is may be one of the highest population immunity levels known worldwide.
