There is no known connection between the new patient and anyone else diagnosed with the disease, known as covid-19. On Wednesday, health authorities revealed the nation’s first case of community transmission, a woman in Solano County, about 90 miles away.
That means the virus appears to be spreading among at least two separate populations, according to people who spoke on the condition of anonymity because the information has not been released publicly.
Meanwhile, the World Health Organization raised its risk assessment of the coronavirus to “very high” Friday, citing risk of spread and impact. WHO officials said their assessment — the highest level short of declaring a global pandemic — doesn’t change the approach countries should take to combat the virus but should serve as a “wake up” and “reality check” for countries to hurry their preparations.
