There are dozens of identified hantavirus species, that are broadly divided into these discovered within the western or japanese hemisphere (“New World” and “Previous World” hantaviruses). Most of those are native to rodents and aren’t thought to make them sick. However some hantaviruses can cross over and infect people, probably inflicting life-threatening sickness.

New World hantaviruses may cause a extreme respiratory situation often called hantavirus pulmonary syndrome, or HPS (Previous World hantaviruses usually tend to trigger a situation referred to as hemorrhagic fever with renal syndrome, with signs just like Ebola an infection). There aren’t any particular therapies for HPS and its mortality charge within the U.S. is round 35%.

On Wednesday, the New Mexico Division of Well being reported that six residents have been identified with HPS to this point in 2023. Two have died, whereas 4 ended up within the hospital needing oxygen or intensive care to outlive their ordeal. The present tally is above the historic common seen within the state, with New Mexico usually reporting three to 4 circumstances a yr.

Hantaviruses can generally be transmitted by way of rodent bites. However extra typically, it’s caught from inhaling contemporary poop and urine particles which were kicked up within the air or from touching their droppings/urine immediately. Just one species of hantavirus—the Andes virus—has ever been proven to be transmitted from individual to individual, however this virus is extra typically present in South America. The primary provider of hantavirus in New Mexico is the deer mouse, and the most typical germ behind human circumstances within the U.S. is known as the Sin Nombre virus.

The primary identified circumstances of HPS within the U.S. have been found within the early Nineties. And although the rodents that carry probably harmful hantaviruses have been discovered all through the nation, severe infections stay very uncommon. In accordance with the Facilities for Illness Management and Prevention, about 850 circumstances of hantavirus illness within the U.S. have been documented between 1993 to 2021, together with some non-HPS circumstances.

Nonetheless, these infections are extra widespread in southwestern states like New Mexico, which was one of many 4 states the place the primary identified outbreaks of HPS occurred. And folks in these areas can take precautions to keep away from the danger of catching hantavirus, well being officers say.

“Everybody in New Mexico ought to find out about hantavirus infections and take the required steps to reduce potential exposures,” stated Chad Smelser, a deputy state epidemiologist, in an announcement launched by the New Mexico Division of Well being. “The important thing to stopping infections is to keep away from publicity to rodents and their nests.”

These steps embrace sealing up houses to forestall rodent infestations, eliminating close by trash or junk piles which may entice rodents to arrange camp, airing out buildings or autos that haven’t been visited for some time, and soaking found rodent nests and droppings with disinfectant earlier than you try to wash them up.
