The newly identified coronavirus claimed its first life outside China, as the number of U.S. cases ticked up to eight and the Pentagon said it was setting up quarantine centers for travelers who screened positive for the illness.

A 44-year-old man in the Philippines from the Chinese city of Wuhan, where the outbreak began in December, died on Saturday, the Philippine Department of Health said on Sunday. The man was one of two confirmed cases in the Philippines, the other being his 38-year-old female companion.

The number of cases has expanded dramatically around the world to more than 20 countries. There are now nearly 15,000 cases of the virus in China, resulting in more than 300 deaths overall. Some 150 people outside China have been sickened.

Heath officials said a University of Massachusetts Boston student in his 20s who had recently visited Wuhan had been infected, raising the number of cases in the U.S. to eight. The man, who went to doctors soon after returning from China, is in isolation and his close contacts are being monitored, they said.

Countries and airlines around the world have limited their contact with China after the World Health Organization designated the coronavirus outbreak a public health emergency of international concern. The U.S., Australia and New Zealand have raised their travel alerts for all of China to their highest levels, “Do Not Travel,” and Indonesia, South Korea and the Philippines imposed new restrictions over the weekend.
