Since Chinese officials disclosed the outbreak of a mysterious pneumonialike illness to international health officials on New Year’s Eve, at least 430,000 people have arrived in the United States on direct flights from China, including nearly 40,000 in the two months after President Donald Trump imposed restrictions on such travel, according to an analysis of data collected in both countries.

The bulk of the passengers, who were of multiple nationalities, arrived in January, at airports in Los Angeles; San Francisco; New York; Chicago; Seattle; Newark, New Jersey; and Detroit. Thousands of them flew directly from Wuhan, the center of the coronavirus outbreak, as American public health officials were only beginning to assess the risks to the United States.

Flights continued this past week, the data show, with passengers traveling from Beijing to Los Angeles, San Francisco and New York, under rules that exempt Americans and some others from the clampdown that took effect on Feb. 2. In all, 279 flights from China have arrived in the United States since then, and screening procedures have been uneven, interviews show.

Trump has repeatedly suggested that his travel measures impeded the virus’ spread in the United States. “I do think we were very early, but I also think that we were very smart, because we stopped China,” he said at a briefing on Tuesday, adding, “That was probably the biggest decision we made so far.” Last month, he said, “We’re the ones that kept China out of here.”

But the analysis of the flight and other data by The New York Times shows the travel measures, however effective, may have come too late to have “kept China out,” particularly in light of recent statements from health officials that as many as 25% of people infected with the virus may never show symptoms. Many infectious-disease experts suspect that the virus had been spreading undetected for weeks after the first American case was confirmed, in Washington state, on Jan. 20, and that it had continued to be introduced. In fact, no one knows when the virus first arrived in the United States.
