Coronavirus case confirmed in Chicago; 2nd infection in U.S.

Coronavirus: What we know As US health officials confirm a second case of coronavirus stateside and continue to monitor dozens of other potential cases, here’s what we know about the virus that has killed more than 25 and sickened more than 800 people in China and other countries. This strain of coronavirus is being called the Wuhan virus – because the outbreak is thought to have originated from a December meat and seafood market in Wuhan, China. Normally infecting small mammals, coronaviruses easily mutate and can spread from animal to human – then human to human. Officials say this strain is more contagious than SARS, but not as severe, and not as contagious as the flu. Symptoms are flu like with severe cases including pneumonia, kidney failure, and death.
