Health officials issue urgent warning
A deadly rodent-borne disease, hantavirus, which has no known cure, has killed four people in the U.S., prompting an urgent health warning from authorities. The Arizona Department of Health Services has reported an alarming rise in cases of Hantavirus Pulmonary Syndrome (HPS).
From January to early July this year, Arizona confirmed seven cases of HPS, three of which were fatal. Additionally, California reported two cases, resulting in one death. The disease, caused by infection with hantavirus, is a severe respiratory illness that can be fatal.
Hantavirus: Symptoms and transmission
Symptoms of hantavirus include fever, headache, and muscle aches, which rapidly progress to severe breathing difficulties. The virus spreads through contact with infected rodents’ urine, saliva, or feces but is not transmitted between humans. In Arizona, the virus is primarily found in deer mice.
Hantavirus was first identified in 1993 following a deadly outbreak among the Navajo tribe near the Arizona-New Mexico border, where it had a fatality rate of about 80%. While most common in the southwestern U.S., the virus can be present wherever there is rodent activity.
Public health officials urge residents to follow specific cleanup procedures if they encounter rodent activity. These include disinfecting rodent droppings and nests, sealing entry points larger than a quarter-inch, and using traps to manage rodent populations.
“The best way to prevent infection is by carefully cleaning up any rodent waste and avoiding contact with rodents,” said Dr. Aaron Glatt, chief of infectious diseases at Mount Sinai South Nassau Hospital.
Context of broader health concerns
This warning follows concerns earlier this year about the spread of the ‘zombie deer disease‘ in Yellowstone National Park, highlighting ongoing fears about zoonotic diseases affecting humans.
