Officials in Washington state on Saturday announced the first death in the United States from the coronavirus.

The person was a man in his 50s with underlying health conditions, Washington State officials said.

The first death comes as officials have announced four cases with unknown origins, raising the possibility that the virus is spreading among the general public in some areas. That includes two cases in California, one in Oregon and one in Washington state.

Experts have raised concerns that a lack of testing means that the virus could be circulating in some areas undetected. California announced on Friday that more test kits are now available in the state, expanding its ability to identify the virus.

Centers for Disease Control and Prevention Director Robert Redfield said Saturday that "the risk to the American public remains low." He said officials expect more cases.

Officials also said about 80 percent of cases appear to not require hospitalization, and the main risk is for older people or those with underlying health conditions.
