The Wuhan virus, which broke out in China last month and has so far infected more than 300 people and killed six, has reportedly reached U.S. shores. The Centers for Disease Control and Prevention is expected to announce Tuesday that a person in Washington state has been infected, making the U.S. the sixth country to experience the outbreak of the respiratory illness, along with China, Taiwan, Japan, Thailand, and South Korea. The patient was hospitalized with pneumonia last week after traveling to Wuhan, China, where the outbreak appears to have originated at a seafood and poultry market. The latest development supports the possibility that it spreads from person to person.
