Washington state continued to report the highest number of new infections, confirming 373, while Wyoming, North Dakota and Maine each registered one case.

Questions were raised on Thursday about Mr Trump’s exposure to the virus, after Fabio Wajngarten, communications secretary to Brazil’s President Jair Bolsonaro, tested positive. He met the US President last week in Florida.
Mr Wajngarten posted a photograph on Instagram with Mr Trump and Vice President Mike Pence from March 8, prompting calls to test the US leaders.
But White House press secretary Stephanie Grisham insisted the two had “almost no interactions” and that there was no need for a test.

The fast-spreading virus also forced more US politicians to quarantine themselves, bringing the number up to nine.
Lindsey Graham, Ted Cruz, Doug Collins, Matt Gaetz, Paul Gosar, Mark Meadows, Julia Brownley, Rick Scott, and Don Beyer have now isolated themselves to contain the spread of the virus.
But the Senate on Thursday cancelled its week-long pause to address the coronavirus outbreak and pass legislation.
The Democratic frontrunner for presidential candidacy, Joe Biden, without mentioning Mr Trump by name, criticised his administration’s response to the crisis.
In Delaware on Thursday, Mr Biden said that downplaying the pandemic “or spreading misinformation is only going to hurt us and further advantage the spread of the disease. But neither should we panic or fall back on xenophobia".
“Labelling Covid-19 a foreign virus does not displace accountability for the misjudgments,” he said.
Mr Biden called for a more urgent search for vaccines and a greater economic response.
