An international effort to contain the deadly coronavirus is on hold, and a US official says it is not yet clear when the US will be able to share data about the epidemic.
A group of 11 nations in the Americas are working on a draft document to give more information to governments and the public about the deadly virus, which has killed more than 8,000 people.
But it has yet to be finalized.
The group has already begun talking to other nations, but no decision has been made, said Dan Merrick, a spokesman for the American delegation.
The World Health Organization said Thursday that more than a third of the global deaths of the virus occurred in the last year.
The U.S. has had the highest number of cases, but health experts say the number of new cases is still well below that of other countries.
The nation with the second-highest number of infections, Brazil, has recorded more than 7,000 new cases, about half the global total.
