There is no country in the world where confirmed coronavirus cases are growing as rapidly as they are in Arizona, Florida or South Carolina. The Sun Belt has become the global virus capital.

This chart ranks the countries with the most confirmed new cases over the past week, adjusted for population size, and treats each U.S. state as if it were a country. (Many states are larger in both landmass and population than some countries.)

The only countries with outbreaks as severe as those across the Sunbelt are Bahrain, Oman and Qatar — three Middle Eastern countries with large numbers of low-wage migrant workers who are not citizens. These workers often live in cramped quarters, with subpar social services, and many have contracted the virus.

They “have found themselves locked down in cramped, unsanitary dorms, deprived of income and unable to return home because of travel restrictions,” The Times’s Beirut bureau chief, Ben Hubbard, has written.

Other countries on the list — like Panama, Kazakhstan and Armenia — are substantially poorer than the U.S.
