Hantavirus fears spark COVID flashbacks, but experts say there’s one major difference

Hantavirus cases are rising, sparking concerns similar to the COVID-19 pandemic, but experts say the two viruses have major differences in terms of transmission and mutation. Hantavirus is mainly a secretion-borne virus and has not mutated significantly, unlike COVID-19. The current outbreak on a cruise ship is attributed to close quarters rather than a change in the virus itself.
