Historically, the majority of US hantavirus cases were concentrated in the Southwest, particularly in states such as New Mexico, Arizona, Colorado, and Utah, where deer mice are common carriers. However, scientists are now detecting infected rodent populations farther east and in more densely populated areas, raising concerns about future human exposure.
Although hantavirus infections remain relatively rare, the disease carries a high fatality rate. According to the Centers for Disease Control and Prevention (CDC), approximately one-third of people who develop respiratory symptoms from hantavirus may die from the illness if not treated quickly.
Early symptoms often resemble the flu, including fever, muscle aches, fatigue, headaches, nausea, and chills. Within days, patients can develop severe breathing difficulties as fluid builds up in the lungs.
Public health officials stress that awareness and prevention remain the best defenses against infection. Experts recommend avoiding direct contact with rodents and taking precautions when cleaning areas where rodents may have nested. Sweeping or vacuuming rodent droppings can release infectious particles into the air, increasing the risk of inhalation.
