Health officials are optimistic that a recent hantavirus outbreak on a cruise ship, which has tragically claimed three lives, will not escalate into a wider epidemic. While human-to-human transmission is rare for hantaviruses, rigorous contact tracing is underway across several countries to identify and monitor those potentially exposed. Hantaviruses typically spread when people inhale contaminated residue from rodent droppings. Though human cases are uncommon, the Andes virus implicated in the cruise ship incident poses a unique concern. This strain may, in rare instances, be capable of human-to-human spread, and viruses can change. Scientists are now urgently investigating the virus to understand potential mutations and its exact transmission pathways. The WHO repeated that the risk to the general public was low even if the Andean strain of the virus, found in several victims, can in rare cases be transmitted among humans.…
