How the new coronavirus stacks up against SARS and MERS
For the third time since around 2003, a coronavirus has jumped from animals to people
Coronaviruses, one of a variety of viruses that cause colds, have been making people cough and sneeze seemingly forever. But occasionally, a new version infects people and causes serious illness and deaths.
That is happening now with the coronavirus that has killed at least 26 people and sickened at least 900 since it emerged in central China in December. The World Health Organization is monitoring the virus’s spread to see whether it will turn into a global public health emergency (SN: 1/23/20).
Among the ill are two people in the United States who contracted the virus during travels in China. A Chicago woman in her 60s is the second U.S. case of the new coronavirus, the Centers for Disease Control and Prevention confirmed January 24 in a news conference.
Officials are currently monitoring 63 people across 22 states for signs of the pneumonia-like disease, including fever, cough and other respiratory symptoms. Of those people, 11 have tested negative for the virus. Two, including the newest case and another patient in Seattle, tested positive, the CDC reported (SN: 1/21/20).
