Why hantavirus is not like COVID, according to infectious disease experts

TL;DR

  • The World Health Organization and infectious disease experts emphasize that the current hantavirus outbreak is not similar to COVID-19 and poses a low risk.
  • Hantavirus is more like 'a wet log' compared to COVID-19, which was like 'dry forest' conditions for a wildfire, indicating it's less likely to spread rapidly.
  • Unlike COVID-19, hantavirus does not spread easily through the air; transmission requires prolonged physical contact, close proximity in enclosed spaces, or exposure to bodily fluids.
  • The Andes virus strain involved in the outbreak is rare and typically spread by rodents, with only this specific strain known to spread person-to-person.
  • The longer incubation period of hantavirus (two to six weeks) aids in containment efforts, contrasting with the shorter incubation period of COVID-19.
