The medical impact of the new coronavirus is coming into sharper focus as it continues its spread in what is now officially recognized as a pandemic.
Its true fatality rate isn’t yet known, but it seems 10 times higher than the flu, which kills hundreds of thousands around the world each year, the United States’ top infectious disease expert told lawmakers last week.
Most people have had mild to moderate illness and recovered, but the virus is more serious for those who are older or have other health problems.
HOW IT SPREADS
Most spread is from droplets produced when an infected person coughs, which are inhaled by people nearby. Transmission from touching contaminated surfaces hasn’t been shown yet, though recent tests by U.S. scientists suggest it’s possible — one reason they recommend washing your hands and not touching your face.
The virus can live in the air for several hours, up to 24 hours on cardboard and up to two to three days on plastic and stainless steel. Cleaning surfaces with solutions containing diluted bleach should kill it.
“While we are still learning about the biology of this virus, it does not appear that there is a major risk of spread through sweat,†said Julie Fischer, a Georgetown University microbiologist. The biggest concern about going to the gym is infected people coughing on others, or contaminating shared surfaces or equipment, she said. Consider avoiding large classes and peak hours and don’t go if you’re coughing or feverish, she suggests.
