CNN News:美国新冠肺炎确诊病例突破100万
CARL AZUZ, cnn 10 ANCHOR: Contact tracing is the subject of today's first report on cnn 10. And of course we'll be explaining what that's all about. I'm Carl Azuz away from the cnn Center but happy to be anchoring your news this Wednesday.
The United States passed a milestone yesterday in the number of its coronavirus cases. According to Johns Hopkins University, more than 1 million cases of the disease have been confirmed in America. That's about a third of the cases confirmed worldwide. And when we produced this show about 58,000 Americans have died from COVID-19.
For perspective, the flu infects roughly 26 million Americans on average each year and it kills an average of 36,000 people. So based on those numbers, the flu infects many more people than coronavirus has, but COVID-19 is more dangerous. Some U.S. states are grappling with decisions on when to allow their businesses to reopen and some have already started doing that.
Antibody testing factors in here. This can be done through blood samples and it can detect if people have had coronavirus even if they don't know it.
