NEW YORK — The Centers for Disease Control and Prevention announced Friday that it has found no evidence that any individual has contracted bubba disease in the United States.

The CDC said it has identified 14 cases of bubba in the U.S. and is treating one person with bubba and two with another strain.

A person can contract bubba by inhaling droplets of infected air from contaminated surfaces or contaminated food, but it is not spread through direct contact.

Infection with bubbae usually results in severe illness, including pneumonia and death.

The virus can cause long-term disability and can also cause severe brain damage.

The outbreak of bubbba virus has been in the news since last week.

On Friday, the Centers for Medicare and Medicaid Services said it had detected the virus in four people who had previously tested positive for it.

The person with the first confirmed case was a U.K. man who contracted bubbe virus while traveling to Thailand.

More than half of the 14 people who tested positive had never visited a U,S.

health care facility, according to the CDC.

The four who tested negative were a U., a U-21 and a U.-23 from Mexico, and a non-U.S.-born U-20.
