It all starts with the virus, which originated in animals before it jumped to people and became communicable from person to person,
according to the Centers for Disease Control and Prevention. Early reports claimed that human infection of COVID-19 began in a so-called “wet market” – places that sell terrestrial and aquatic wildlife from around the world for human consumption.

Where and how did COVID-19 start?
"It started in what we call a 'wet market.' You would it a 'wet market' in Asia, you'd call it a 'bushmeat market' in Africa," Fair said. "These are markets typically where have wildlife, livestock and humans in close proximity together. We know that's a recipe for a pandemic just from a historical precedence. That’s where SARS came from when it first emerged. That’s most often where Ebola will emerge from in Africa.
"Those kind of markets, which are very common throughout the world, are breeding grounds for epidemics and pandemics. We've been working there for years, myself included, in Wuhan amongst other places in China in those wet markets surveilling both those areas and the people who work in them to look for new and emerging viruses.
