Hantavirus Detected in Over 30 Mammal Species Across New Mexico

Recent research from the University of New Mexico has revealed that hantavirus, which is primarily associated with deer mice, is also carried by over 30 other small mammal species, including ground squirrels, chipmunks, gophers, and rats. This study, published in PLOS Pathogens, found the virus in a significant portion of mammals sampled in the state, particularly in the Four Corners region, where the first North American outbreak occurred in 1993. The virus poses a serious health risk, with a fatality rate of around 35%, and is mainly contracted by humans through inhalation of aerosolized droppings or contact with contaminated surfaces. Health officials urge caution during cleaning, especially in areas where rodent droppings may be present, recommending protective gear and proper sanitation methods. Despite the high prevalence of hantavirus in various species, researchers are still investigating why human cases are predominantly reported in the Four Corners area. Overall, while the risk of transmission remains low, ongoing awareness and preventive measures are essential.
