CNN News:3月美国工业生产和制造业均出现下降 为1946年来最大月度跌幅

CARL AZUZ, cnn 10 ANCHOR: Industrial production and manufacturing, two important parts of the American economy factor into our first report today on cnn 10. I'm Carl Azuz, happy to have you watching. According to the U.S. Federal Reserve, the country's central bank, 5.4% is how much America's industrial production dropped in March as factories stopped operating.
Manufacturing fell by 6.3 percent as cut backs were made in areas like car production, auto parts manufacturing and furniture making. The last time these numbers decreased by this much in a month, the year was 1946. World War II had just ended.
Industries were shutting down their production of war effort materials and transitioning into making consumer products again. 74 years later, it's the coronavirus pandemic that's closed factories. No one knows yet how long it will take to get industry running the way it was before COVID-19 entered America.

According to Johns Hopkins University, more than two million coronavirus cases have been confirmed worldwide. Over 610,000 of them are in the United States. And while there's still a lot that doctors don't know about the disease, a new study suggests that people might be most likely to infect others before the carriers even show symptoms themselves.
This was published Wednesday in the journal "Nature Medicine". But the study relied on patients memories of when they first started showing symptoms so it might not be entirely accurate. Still, a growing amount of research indicates that people who feel healthy are helping spread coronavirus.
So the U.S. government's recommending that healthy people keep their faces covered whenever they leave the house.
