Further examination of the COVID-19 virus has shown evidence of snake DNA. The open air market in China where the virus originated also sold freshly butchered snakes as well as bats. Snakes do hunt bats so the link is a possible one.
Viruses require a LIVING host in order to be replicate (viruses cannot replicate themselves. They, viruses, are NOT alive) Thus viruses cannot "grow" in food.
As to eating an infected animal (human or otherwise) one would assume that cooking would be involved. Experience with the related SARS viruses shows that cooking for 30 minutes to 60C will inactivate the virus. So don't eat raw humans.
The virus is passed through direct contact with an infected persons body fluids, fomites from cough or sneeze, contaminated surfaces (the virus can remain active for a few hours on a surface). Bleach/chlorine-based disinfectants, either solvents, 75% ethanol, peracetic acid and chloroform will inactivate the virus on hard surfaces and to a degree on skin but as Marcel posted not completely.
Masks will not block the virus BUT the (P) class masks can filter the fomites from the air. The (N) class are not as effective especially if the fomite has any "oily" component. A P95 mask will filter 95% of the particulate matter from the air.
COVID-19 vs Flu
So far this flu season, about 0.05% of people who caught the flu have died from the virus in the U.S., according to CDC data.
The death rate for COVID-19 appears to be higher than that of the flu.
In the study published Feb. 18 in the China CDC Weekly, researchers found a death rate from COVID-19 to be around 2.3% in mainland China. That's much higher than the death rate linked to flu, which is typically around 0.1% in the U.S., according to
The New York Times.
Even so, the death rate for COVID-19 varied by location and an individual's age, among other factors. For instance, in Hubei Province, the epicenter of the outbreak, the death rate reached 2.9%; in other provinces of China, that rate was just 0.4%. In addition, older adults have been hit the hardest. The death rate soars to 14.8% in those 80 and older; among those ages 70 to 79, the COVID-19 death rate in China seems to be about 8%; it's 3.6% for those ages 60 to 69; 1.3% for 50 to 59; 0.4% for the age group 40 to 49; and just 0.2% for people ages 10 to 39. Nobody 9 and under has died of this coronavirus to date.
