The first case of an infection with a new coronavirus has been discovered in the U.S. A person traveling from Wuhan, China, to Washington state was diagnosed with pneumonia last week. Subsequent tests showed that the person has the virus, which can cause pneumonia. In severe cases the coronavirus can lead to death. The case was detected prior to the implementation of screening at three U.S. airports last Friday.
The Centers for Disease Control and Prevention is expected to announce details at a press conference this afternoon.
About 300 cases of the virus and six deaths have been reported in China, and health officials there and around the world are ramping up precautions to stem the spread.
Chinese authorities are trying to control the flow of people in and out of the eastern city of Wuhan, where a strain of the coronavirus was discovered last month. Wuhan’s mayor has asked residents to stay in the city to try to prevent the spread of the virus, which can cause respiratory symptoms such as pneumonia. “Cars may be randomly tested in case wild animals, a potential source for the virus, are transported, and tour groups are prohibited from leaving the city,” NPR’s Amy Cheng reports from Beijing.
Cases of coronavirus, named 2019-nCoV, have also been confirmed in Japan, Thailand and South Korea.
Many airports around the world, including the three in the U.S. — JFK in New York, SFO in San Francisco and LAX in Los Angeles — are setting up added security screenings for passengers coming from infected areas.
“Russia, India and North Korea have all started checking people for fever on inbound flights from China,” NPR’s Jason Beaubien says. Australia and the Philippines are also checking passengers and have quarantined some suspected cases.
The rising international concern about the coronavirus comes ahead of Lunar New Year, which is a major holiday in China where millions of people travel around the country and internationally.
Wuhan authorities are testing whether passengers have fevers at transportation terminals around the city using 35 stationary infrared thermometers and more 300 handheld ones, according to China’s Xinhua news agency. Passengers set to travel to Wuhan are also being offered free ticket cancellations or changes.
“The Wuhan airport, it’s like a war zone because it’s all controlled with all the security, all the medical staff,” Linfa Wang, a virologist at Duke-National University of Singapore, tells NPR. “You line up and then you go through group by group.”
The World Health Organization says the virus likely first spread to humans through transmission from an animal at a live animal market in Wuhan.
On Monday, a Chinese government epidemiologist appeared on television and stated that there was evidence the virus could be transmitted from human to human. “The concern with that is that it can basically go viral,” Beaubien reports. The coronavirus is also raising concerns because it has shown to spread in medical environments – among people who are likely taking appropriate precautions to avoid infection.
Chinese authorities have come up with a new test for diagnosing the virus, Beaubien says, and are calling on people to take measures to prevent its spread such as covering their mouths when coughing or wearing face masks. These masks are reportedly selling out in stores and online retailers in the country.
Wang says this virus is also concerning because there are still many aspects that aren’t well understood by health officials. “The enemies are in the dark, and we don’t know them,” he said. “This new coronavirus is in the same family as SARS, but it’s different from SARS.” SARS, which is short for Severe Acute Respiratory Syndrome, killed nearly 800 people during an outbreak in 2003.
The World Health Organization has scheduled a meeting Wednesday to weigh whether the coronavirus should be declared an international public health emergency.
Wang is invited to that meeting, and expects the idea of travel restrictions to be discussed. “It’ll be a tough decision, and I don’t want to be the person to make that decision,” he says, given the sheer number of people on the move during the [Lunar New Year] holiday.
