Could Mumbai's Slums Be Headed to Herd Immunity?

Anjana Pasricha

   NEW DELHI - A recent survey in Mumbai's slums finds that more than half
   of the residents have developed antibodies for COVID-19, indicating
   that some of India's most densely packed settlements, which pose the
   greatest challenge in containing the spread of the infection, could be
   heading toward "herd immunity."

   While urban slums may be inadvertently developing population immunity,
   though, officials are ruling it out as an option in tackling the
   rampaging infection, saying it could never be a choice but only an
   outcome.

   "Herd immunity" is achieved when a large part of the community develops
   antibodies against the virus, acting as a wall against its further
   spread.

   India is a global hotspot for COVID-19, with infections topping 1.6
   million.
