As concerns about the spread of hantavirus emerge, right-wing and far-right figures are spreading conspiracy theories on podcasts and social media that the virus came from a lab and may be a new “plandemic” (planned pandemic) created to push vaccines, disrupt upcoming elections, or achieve other nefarious goals.
In early May, a cruise ship sailing the Atlantic Ocean experienced an outbreak of hantavirus, a typically rodent-borne virus, causing at least three deaths and at least eight others to become ill or test positive for the virus. The World Health Organization has said that “the risk of hantavirus spreading to the general population is ‘absolutely low,’” with the organization’s head of epidemic and pandemic preparedness saying, “This is not the start of an epidemic, this is not the start of a pandemic.”
Despite these assurances, some right-wing and far-right figures on podcasts and social media have been baselessly claiming that hantavirus is the beginning of a planned outbreak. Others were more specific, saying that organizations like the World Health Organization were responsible for the spread of the virus. Another emerging talking point is the suggestions that the virus was released to disrupt the 2026 midterm elections.
These claims about hantavirus are essentially recycled versions of what right and far-right figures pushed during the coronavirus pandemic. Conspiracy theories and misinformation about COVID-19 helped drive down COVID vaccination rates and primed people to reject other vaccines. Recycling the same claims could help further entrench vaccine resistance and erode public trust in health institutions at a time when the Trump administration has already been cutting federal resources for pandemic preparedness.
