What we know about the coronavirus cases in the US
U.S. health officials released an elevated warning Tuesday about the spread of coronavirus.
“Ultimately, we expect we will see community spread in the United States," said Nancy Messonnier, a top official at the during briefings with lawmakers and reporters.
“It’s not a question of if this will happen, but when this will happen and how many people in this country will have severe illnesses.”
The coronavirus, which has sickened more than 80,000 and killed nearly 2,500 people worldwide, belongs to a large family of viruses that mostly sicken animals. But this coronavirus, like SARS and MERS, "jumped the species barrier" to infect people on a large scale, according to officials from the Centers for Disease Control and Prevention.
Officials scrambled to halt the spread of a burgeoning virus Tuesday, from northern Italy where troops were dispatched to enforce quarantines and schools were shuttered, to South Korea, where some neighborhoods in a city of 2.5 million were brought to a near standstill.
New clusters of the illness popped up far from its apparent point of origin in China, fueling apprehension in world financial markets and political institutions. The spread fueled an increased sense of urgency among officials in some of the wealthiest nations in Europe and Asia, as well as in countries like Iran, with far fewer resources to stem the disease. But many remained uncertain about how best to contain it.
The U.S. began putting travel restrictions in place in January, temporarily denying entry to foreign nationals who visited China in the 14 days before their arrival to the U.S., a health official said.
Restrictions also apply to U.S. citizens who have been in China's Hubei province, the epicenter of the coronavirus outbreak, in the two weeks prior to their return to the United States. Upon their return, those citizens will be subject to a mandatory quarantine of up to 14 days, Health and Human Services Secretary Alex Azar said Friday.
Here's what we know about the cases in the U.S.:
As of Feb. 25, coronavirus cases have been diagnosed in six states: Arizona (one case), California (eight), Illinois (two), Massachusetts (one), Washington (one), and Wisconsin (one).
Twelve of these 14 cases were patients who had traveled to China, and two cases occurred through person-to-person transmission. That case involved two patients who lived in the same household. An additional 39 cases were reported among repatriated U.S. citizens, residents, and their families returning from Hubei province, China (three), and from the Diamond Princess cruise ship that was docked in Yokohama, Japan (36). Thus, there have been 53 cases within the United States. No deaths have been reported in the United States, according to the CDC.
Who's still at risk
The CDC is continuing monitoring potential cases in the U.S.
Though health officials have confirmed one case of person-to-person contact, they maintain that the immediate risk to the public is low.
What's being done
On Jan. 30, the U.S. State Department raised its China travel advisory to "Do Not Travel" and warned that it could put travel restrictions into effect with "little to no advance notice." The CDC recommended U.S. citizens avoid nonessential travel to the country.
"If you are a traveler who has recently returned from the impacted area, we want you to be vigilant with the symptoms and signs of this coronavirus," said Dr. Nancy Messonnier, director of the CDC's National Center for Immunization and Respiratory Diseases.
Multiple airlines have temporarily suspended all flights to China.
Local health officials are cracking down on misinformation related to the virus, including fake reports of confirmed cases and conspiracy theories about its spread. The most accurate information comes from county, state and federal health departments and is updated regularly as officials learn more.
Otherwise, the CDC encourages people to follow flu season protocol: Wash hands with soap and water for at least 20 seconds, avoid ill people and stay home and avoid public situations if they're ill. A potential coronavirus vaccine is currently on its way to U.S. government
The CDC does not recommend Americans wear surgical masks in public. Surgical masks are effective against respiratory infections but not airborne infections.
