This video from Vox is a few days old but is still a good look at why diseases like SARS and COVID-19 originate in China. It involved the designation of wild animals as “natural resources” by the Chinese government, which caused a large increase in wildlife farming, with many more and different kinds of animals being put into contact with humans and each other on a regular basis. Add illegally trafficked animals into the mix, and you’ve got the right conditions for diseases to jump from the animals to humans. Then potentially infected animals and their meat, accompanied by potentially infected humans who raised those animals and butchered that meat, are then brought to the wet markets for sale to the public.
It’s important to note, as Christopher St. Cavish says in the LA Times, “most wet markets are not wildlife markets, and confusing the two is dangerous”:
“Wet” markets are what China calls its fresh food markets, the kind you see all over the developing world and in many parts of Europe, where small stalls sell fresh vegetables and butchers sell meat, primarily pork. They are the daily market for tens of millions of Chinese who prefer to talk to the people who sell them produce, meat, seafood and tofu, and in small cities, are often the only outlet for small-scale farmers who can’t meet the supplier requirements for supermarkets.
I couldn’t find any up-to-date information on which animal is suspected of passing the coronavirus responsible for COVID-19 along to humans, but bats are a prime suspect with a possible pangolin intermediary. (via open culture)
