In one instance, 15 customs officers in Belgium contracted psittacosis after being exposed to infected parakeets. A comprehensive review of the disease by the ICAR–Indian Veterinary Research Institute in 2021 noted it had “critical zoonotic potential.” But it’s just one of many pathogens that can cross the species barrier, sometimes adapting to new hosts in the process.  For decades, scientists have tried to inform the public that wildlife trade brings different species into unnatural proximity, creating opportunities for diseases to spread to animals that have no immunity to them.
