Very good question. The New York metro area, which includes parts of New Jersey, is the perfect breeding ground for a common cold virus, and this virus is especially dangerous. N.Y. has experienced a cold, wet winter that lasted for four months. Older people, the homeless, and the poor dominate the downtown area, and they rely on public transportation. A dangerous virus is easily passed on from person to person. Many probably didn't know what hit them.
Total deaths in three and a half months in the U.S. is 16,548. 7,067 are in New York, 1,700 in New Jersey, 1,076 in Michigan, and 702 in Louisiana for a total of 10,545. That leaves 6,003 for the other 46 states. That is the normal death rate among the old, the sick, the poor, and the homeless for 46 states.
