Since the first cases of hantavirus on the MV Hondius cruise ship were reported to the World Health Organization (WHO) on May 2, misinformation has rapidly flooded the Internet.
Much of it is familiar, echoing the conspiracies of the COVID pandemic, such as false claims about the drug ivermectin being known to effectively treat the infection and vaccines causing the outbreak. Hantavirus-related misinformation is “operating not like isolated rumors but more like a standing online ecosystem,” says Katrine Wallace, an epidemiologist at the University of Illinois Chicago. This kind of thinking is “ready to plug and play and rapidly attach itself to any kind of emerging health threat within hours,” she says.
But not all faulty information online is being spread in bad faith. Though public health officials have said the hantavirus outbreak poses a low risk to the public, fear is its own kind of contagion. “We’re still recovering from the collective trauma of going through COVID-19. People are still carrying that residual fear, exhaustion and distrust,” says Monica Wang, a public health researcher at Boston University, who specializes in health misinformation.
