The CDC is investigating the possibility of an airborne, highly contagious, new virus, and it could spread across the globe, experts said Thursday.
The agency, which is still in the initial stages of the coronavirus outbreak, has sent out notifications to all U.S. public health agencies that it is investigating a new strain of the virus.
The new strain, known as CPF-19, was first identified in China last month and has since been detected in the United States.
According to the Centers for Disease Control and Prevention, the virus has killed nearly 400 people and sickened more than 4 million, mostly in the U.K. and Australia.
The new strain was isolated from an unidentified human, the CDC said in a statement.
It was also linked to a rare case of coronaviruses, which has now been identified in four countries, including the United Kingdom, where two deaths have been linked to it.
The latest case, which was identified in a Northern California hospital, was identified as a patient with CPF 19 who tested positive for the virus on March 24, according to the CDC.
The patient is in a stable condition and the outbreak is under control, the agency said.
The coronavirotosis pandemic is the worst in U. S. history and is being led by coronaviral strains like CPF19 that are now circulating across the world.
It is a virus that has killed hundreds of thousands of people, including hundreds of children.
The U.N. is urging all countries in the world to implement mandatory testing for coronavireptids, including CPF.
The United States is among the countries with the highest rates of testing, with the CDC saying there are more than 30 million tests administered each year.
The CDC has not officially reported any new cases, but some experts have said it could be a very bad time for those living in affected countries, especially if they are infected.
It could be very difficult for them to travel and may make it very difficult to stop transmission, said David Satterfield, director of the Institute for Health and Health Systems at the University of Wisconsin-Madison.
The World Health Organization says coronavillosis cases in the Western Hemisphere have surpassed the number of new cases reported in the same period in 2015.
The virus has been blamed for at least 11 deaths, including at least one in China, and two in the Philippines.
The World Health Assembly recently called for more international action to prevent the virus from spreading and urged countries to make life-saving interventions to curb the spread of the disease.
