Jordan on Monday began releasing releasing thousands of travelers who were quarantined for the last two weeks at five-star hotels on the Dead Sea in order to prevent the spread of the new coronavirus.

More than 4,200 Jordanians and 1,500 foreigners have been held at the hotels. The Jordanians will be sent home via Uber, the popular ride-hailing service, and are requested to remain at home for another 14 days.

Travelers with other nationalities will be released on Tuesday. It was not immediately clear where they would go, but authorities said they would be in contact with their embassies and the Foreign Ministry.

Jordan has reported 259 infections and three deaths from the COVID-19 illness caused by the virus. At least 18 people have recovered.

The virus causes mild symptoms, including fever and cough, in most patients, who recover within a few weeks. But it is highly contagious and can be spread by people showing no symptoms. It can also cause severe illness and death, particularly in older patients or those with underlying health problems.

The virus has infected more than 720,000 people worldwide, causing more than 34,000 deaths, according to data gathered by Johns Hopkins University. More than 150,000 have recovered.

Jordan halted all flights and closed its borders on March 16. It later imposed a round-the-clock curfew for three days, before providing limited times for people to shop for basic goods on foot.
