Wild-Animal Markets Pose Rising Pandemic Threat

Live-animal markets across Southeast Asia continue operating as natural laboratories for deadly pathogens despite warnings from public health experts about their role in disease transmission, according to new research published in Nature.

Scientists studying markets like Jakarta's Jatinegara found that coronavirus detection rates in trafficked animals increase dramatically along supply chains, with rats sold at Vietnamese markets testing positive at rates ten times higher than those caught in fields. Pangolins confiscated in Vietnam showed a seven-fold increase in coronavirus infections compared to animals seized earlier in the smuggling process.

The research comes as political headwinds have severely reduced funding for pandemic preparedness, with the Trump administration terminating a $125-million disease monitoring program and cutting all USAID functions. Scientists report growing reluctance from government officials to authorize publication of pathogen discoveries, fearing stigma and trade restrictions, while wildlife traders increasingly avoid participating in studies that could reveal new health risks.
