The hantavirus outbreak is prompting Covid flashbacks

WASHINGTON — The deadly outbreak of a rare strain of hantavirus on a cruise has generated echoes of the pandemic era, including a reprise of a familiar drumbeat of questionable theories from social media personalities prominent for their Covid-19 skepticism.

At the moment, ironically, the public health establishment and the conspiracists challenging it actually seem to agree on the big picture: Hantavirus is not like the Covid-19 virus, and for now, the risk to the general public remains low.

But the speed at which a handful of people who became influential amid Covid-19 have begun recycling theories, from baseless suggestions about the origin of the current outbreak to unproven treatments, illustrates a new reality for any emerging public health threat.
