Rising Hantavirus Cases Prompt Reflection on COVID-19

Americans are starting to think more critically about the coronavirus pandemic as hantavirus cases begin to increase.

Experts suggest that, unlike COVID-19, which rapidly spread from an exotic species, hantaviruses likely won’t follow the same pattern. The Andean virus, linked to a recent outbreak on the MV Hondius cruise ship, is the only known strain that appears to transmit from person to person, typically requiring prolonged close contact.

Dr. Mark Siegel, a senior medical analyst, explained that there’s “no comparison” between hantaviruses and coronaviruses. “Sure, they’re both single-stranded RNA viruses,” he shared. “But hantavirus has stayed pretty much the same for decades.”

He emphasized that while the coronavirus evolved and created numerous complications, this particular hantavirus seems stable. “We’re unsure why it started changing over time,” he noted. “But it looks like our understanding of its genetics holds true.”

Siegel pointed out that the key difference lies in how they spread; while coronaviruses are airborne, hantaviruses mostly transmit through secretions but can also be airborne through dust or feces. “It’s tricky, not like how respiratory droplets travel,” he added.

Disturbingly, he stated that while human-to-human hantavirus transmission is rare, it’s not impossible. In the U.S., there have indeed been sporadic cases over the years, but it remains an unusual occurrence.

Interestingly, some factors might be shifting. Rising temperatures could be pushing rodents further north, potentially leading to increased hantavirus exposure.

As for the cruise ship outbreak, Siegel suggested it doesn’t indicate that the virus is changing; rather, it showcases how close quarters can facilitate the disease’s spread. “We’re not really seeing secondary transmission patterns,” he reiterated, pointing to the tight living conditions onboard.

He drew a comparison to avian influenza, explaining that it primarily arises from animals and occasionally impacts humans. “There are countless birds, and while we often wonder if avian flu could trigger a pandemic, it requires significant mutations to do so,” he elaborated. “This hantavirus is an animal virus too; it would need to mutate considerably to spread effectively between humans.”

Siegel concluded with caution, stating that if one contracts this virus, it’s serious, but notes, “This virus is quite difficult to catch.”

Amid these discussions, concerns about another pandemic echo. Siegel reassured that just because one virus is prominent does not imply others will be. “I’m really more worried about the flu,” he said, referencing its airborne nature and tendency to mutate. “We’re comparing apples and oranges here, and such comparisons can provoke unnecessary fear.”
