U.S. President Donald Trump, seeking to calm U.S. stock markets which fell for the fifth consecutive day, said the United States was “very very ready” to face the virus threat.

Asked by reporters whether he was considering restricting travel to and from South Korea, Italy and other countries where the number of infections have exploded in the last week, Mr. Trump said everything was on the table.

“At some point, depending on what happens, we may cut certain additional countries off, like we've had to do with China, and we hope we can open it up to China soon as possible,” Mr. Trump said in a live broadcast.

Global spread

Chinese health authorities said the number of new deaths stood at 29 on Thursday, the lowest daily rate since Jan. 28. The virus that can lead to pneumonia has now killed a total of 2,744 people in the country, mostly in the central province of Hubei where it originated late last year.

It has infected about 80,000 people, the vast majority in China, and its rapid spread through countries such as Italy, Iran and South Korea has raised the risk of a pandemic.

As panic increased, Mexican authorities barred a cruise ship from docking at one of its ports over what the ship's company said was a single case of common seasonal flu. The ship was eventually allowed to enter the Cozumel port.

The United States is managing 59 cases so far - mostly Americans repatriated from the cruise ship in Japan.

Italy reported another 100 cases nationwide, taking the total in Europe's biggest hotspot to more than 400, while the death toll rose to 12.
