Concerns and warnings about the spread of corona have continued in the United States, where there is no community infection. President Trump praised himself for being well-controlled, but health officials expressed conflicting views.

The Centers for Disease Control and Prevention says it is only a matter of time before the country's spread.

[Director of the Messonnier / American Centers for Disease Control and Prevention: We expect to see regional expansion in the US This is not a matter of whether or not it will happen, but when it happens.]

Therefore, they said they will maintain a dual-access strategy that minimizes the US impact of the outbreak, along with measures to prevent the introduction and spread of the virus.

At the Congressional Hearing, the Minister of Health and Welfare says he expects more infections in the United States.

[Aiza / Health and Welfare Minister: You can't completely block the United States from viruses like the hermit. We need to be realistic.]

But Trump was optimistic that the United States is well controlled.

[Trump / President: If you ask about the coronavirus, you know, it's well controlled in the United States.]

Trump also talked with China after discussing China, South Korea and Italy, adding that they are working very hard.

Contrary to the president's optimism, the New York stock market plunged for two straight days.
