(CNN)The total number of novel coronavirus cases in the United States jumped by two dozen over the weekend, as the first two deaths from the outbreak were confirmed.
New cases of the virus were announced in Oregon, Rhode Island, Washington state, and Florida on Sunday, bringing the US total to 89 as of Monday morning, up from 65 on Friday night.
The new cases prompted emergency declarations in at least two states and sparked new warnings.
Dozens of new cases
At least 18 new cases were announced across the country on Sunday, including the first two cases ever reported in Florida.
Those cases involve one resident of Hillsborough County who tested positive and has a history of travel to Italy.

Jay Inslee declared a state of emergency after the first death was confirmed on Saturday in King County. The patient was a man in his 50s who had underlying health conditions, Dr. Jeffrey Duchin, health officer for Seattle and King County said during a news conference on Saturday. He said he and other health officials were made aware of the case on Friday.
