It’s the same cruise associated with a confirmed case announced previously in Sonoma County.”As the case appears connected to travel, it most likely does not represent an instance of local community spread,” Placer County Public Health said in the press release.The Placer County patient is critically ill and in isolation at a local hospital. Close contacts of the individual are being quarantined and monitored.The county has declared a local health emergency as well as a local emergency.“We expect to see additional cases in coming days, including cases of community spread, not linked to travel,” said Health Officer Dr. Aimee Sisson. “We are declaring these emergencies today so we will be able to activate and deploy resources to adequately respond to an increase in cases.”As of Tuesday, the CDC counted 108 confirmed and presumptive positive cases of COVID-19 in the United States. That number includes 60 Americans whose cases were confirmed by the local U.S. health systems, 45 who were repatriated from the Diamond Princess cruise ship quarantined off the coast of Japan and three who were repatriated from Wuhan, China, where the virus emerged back in December.So far, nine people sickened with the virus in the United States have died.More than 80,000 people have been infected with the virus in China, mostly in central Hubei province, which includes Wuhan, the epicenter of the outbreak, and nearly 3,000 of them have died. Meanwhile, over 10,000 have tested positive for the virus in 72 other nations and 166 have died, according to the latest data from the World Health Organization, which has declared the outbreak a global health emergency.Copyright © 2020, ABC Audio.
