Doesn't clear them out of western countries, only kills the ones in New Delhi, and would cause them to scatter more.
Has to be a bioweapon, ideally seeding major anglosphere cities and then a major deployment against a hindu festival, pic related. The trick is to make it so they don't turn into refugees or flee in the wrong direction.
They gather for the festival, are infected, then spread it throughout the country and communities travelling back, then run from places that also have the disease (western countries with unaffted populations).
