Coronavirus spreads in cities.
Did you know Kerala has no cities?
No city from Kerala is in Top 50 in India.
Kochi, largest in Kerala, is 75th in population.
So that's what "Kerala model" is. No cities.
Of course then you'd have to find a job in the Gulf.
But that's okay, because that's a lovely "workers paradise" run by secular law.
During 2011 census, seems Kerala was embarrassed about not having cities.
So they took huge extra areas around their cities and counted them as "metropolitan area"
This was so embarrassing that 2011 Census put official disclaimer that these should not be compared with rest of India
