The Independent Medical Examiner’s Office in Oklahoma says it’s “a little bit crazier” than coronaviruses.
A coronaviral death has been declared in the state, which has had no confirmed cases of the virus in its history.
The coroner said his office is still awaiting a report from the National Institutes of Health on whether coronavirin is safe for people to take.
Oklahoma State Department of Health spokeswoman Kelly Smith said coronavirs are considered life-threatening when taken in large numbers and should not be administered to children under the age of two.
“Any person who has received any of these drugs should call 911 or the nearest hospital immediately, and not continue to take the drug, she said.
Smith said coronoviruses are “a real concern for all Oklahomans”, but said there are no clear cases of people contracting them.
It is still unclear what the virus is and how it spreads.
