38. The Northeastern U. modelers believe that by March 1 there were already 28,000 cases

in 5 cities alone -- not including cases in other parts of the country.. But the government was only recognizing 23.

And now the public health department in Seattle has found evidence we could have had cases as early as late December. That's not unrealistic when we know that there were approximately 14,000 travelers to the US from China every day in December, and many of them landed in Seattle, and that the modelers think Seattle had 2300 cases only two months later.

By the time New York City confirmed its first case of the coronavirus on March 1, thousands of infections were already silently spreading through the city, a hidden explosion of a disease that many still viewed as a remote threat as the city awaited the first signs of spring.

Hidden outbreaks were also spreading almost completely undetected in Boston, San Francisco, Chicago and Seattle, long before testing showed that each city had a major problem, according to a model of the spread of the disease by researchers at Northeastern University who shared their results with The New York Times.

Even in early February — while the world focused on China — the virus was not only likely to be spreading in multiple American cities, but also seeding blooms of infection elsewhere in the United States, the researchers found.

In five major U.S. cities, as of March 1 there were only 23 confirmed cases of coronavirus. But according to the Northeastern model, there could have actually been about 28,000 infections in those cities by then.

U.S. Customs and Border Protection says it processed an average of 371,780 people at U.S. airports each day in the last fiscal year, although February travel demand is much lower than in the summer. Some 14,000 people flew into the U.S. from China each day — almost 5 million for that year.
