“Human interactions with live animals make a host jump more likely to occur,” Dr Geoghegan said, and live animal markets are a massive source of these interactions. “These locations can act as mixing pots, and you can have animals defecating, urinating, they’re stressed maybe, you’re bringing together the different species that may not be together,” Professor Hayman said. “And if hand hygiene and stuff like that isn’t optimal, then this is where you have the opportunity for an infection to go from one species to another, and that includes humans.” Dr Field said live animal markets are an absolute recipe for that kind of thing to happen. “You’ve got this mixing of species and this potential mixing of viruses in these animals that are under stress, sick and dying as they’ve gone from their wild environment to the market.”
