BEIJING—A preliminary investigation into viral pneumonia illnesses sickening dozens of people in and around China has identified the possible cause as a new type of coronavirus, state media said on Jan. 9.
Chinese health authorities did not immediately conform the report from state broadcaster CCTV.
The novel coronavirus is different from those that have previously been identified, CCTV said.
Laboratory experts as of Wednesday evening had found the novel coronavirus among those who were infected, CCTV said, adding that more research must be done before a conclusion is reached.
Possible cases of the same illness have been reported in Hong Kong and South Korea involving recent travelers to Wuhan.
In Hong Kong, 15 patients with symptoms of respiratory illness were being treated as of Sunday. And a Chinese woman who works for a South Korean company was diagnosed on Tuesday with pneumonia, the Korea Centers of Disease Control and Prevention said.
SARS, or severe acute respiratory syndrome, first infected people in southern China in late 2002, and the illness spread to more than two dozen countries. More than 8,000 people were sickened and nearly 800 died, but none have been reported since 2004. The new illnesses had raised fears of a SARS recurrence.
Another coronavirus caused MERS, or Middle East respiratory syndrome. That outbreak started in Jordan and Saudi Arabia in 2012 and spread into about two dozen other countries. About 2,500 lab-confirmed cases have been reported, including more than 800 deaths, with cases continuing to be seen in recent years.
On Wednesday, the U.S. Centers for Disease Control and Prevention put out a health alert advising physicians who treat patients with pneumonia-like illness to consider a possible link to the Chinese outbreak and to wear masks and take other precautions in treating patients who recently traveled to Wuhan.
The CDC this week also advised U.S. travelers going to Wuhan to avoid animals and sick people and wash their hands often.
