Officials Seek to Calm Public as New US Virus Cases Reported Associated Press PORTLAND, OREGON - The coronavirus may have been circulating for weeks undetected in Washington state, a preliminary finding that could mean hundreds of undiagnosed cases in the state that's also home to the nation's first confirmed infection and now the first death, researchers said Sunday after analyzing genetic samples of the pathogens. State and local authorities stepped up testing for the illness Sunday as the number of new cases grew nationwide, with new infections announced in Illinois, Rhode Island and Washington state. Authorities in the Seattle area said two more people had been diagnosed with the coronavirus, both men in their 60s who were in critical condition. Those cases brought the numbers in the Seattle area to six. Fifty more people in a nursing facility in Kirkland, Washington, are sick and being tested for the virus. .
