More than a dozen people have died from the hepatitis B coronavirus, according to a report from the Centers for Disease Control and Prevention.
The report released Monday, which comes as lawmakers and health officials grapple with the spread of the virus, said the deaths came in different stages of illness.
The study did not provide details on the dates or locations of the deaths.
The CDC does not keep records of people who die from hepatitis B, although some state and local governments have done so.
The Centers for Diseases Control and the Food and Drug Administration have launched an investigation into the death.
