Third cases of novel coronavirus pneumonia were found in the United States. According to US media reports, 4 new cases of new crown pneumonia were found in local health departments in California, Oregon and Washington state. Three of them had neither travel history nor contact with tourists or known cases: including a woman with chronic disease in California, a high school student in Washington state and a school staff member in Portland, Oregon. US media said this may mean that there is a possibility of community transmission of new coronavirus in the West Bank of the United States. The US Food and Drug Administration (FDA) has taken measures to speed up hospital testing. According to reports, previous testing policies in the US have been criticized for their cumbersome and time-consuming procedures.
