HPS is more common in South America than in North America. Cases have been identified in Argentina, Chile, Uruguay, Paraguay, Brazil, and Bolivia. Andes virus causes HPS in Argentina and Chile and is the only hantavirus known to have been transmitted from person to person.
In fact, it has been found in 34 states, although the majority of cases have been found in New Mexico, Colorado, Arizona and California. In the summer of 2012, the largest outbreak of Hantavirus since 1993 occurred in Yosemite National Park. Ten people were infected, ranging in age from 12 to 56.
Approximately 12 percent of deer mice carry hantavirus. The deer mouse (Peromyscus maniculatus) is the primary reservoir for Sin Nombre Virus, the strain of hantavirus responsible for the human cases in Yosemite National Park, and most human cases in the United States.
away, should be left outdoors in the sunlight for several hours or in an indoor area free of rodents for approximately one week before final cleaning. After that time, the virus should no longer be infectious. Wear rubber, latex or vinyl gloves and wipe the items with a cloth moistened with disinfectant. detergent.
Early symptoms are general and include fever, fatigue, and muscle pain. Other symptoms may include headache, nausea (a feeling of sickness in the stomach), vomiting, diarrhea (loose stool/poop) and dizziness.
Only some kinds of mice and rats can give people hantaviruses that can cause HPS. In North America, they are the deer mouse, the white-footed mouse, the rice rat, and the cotton rat. However, not every deer mouse, white-footed mouse, rice rat, or cotton rat carries a hantavirus.
What are the symptoms of hantavirus infection? Hantavirus infection can have no symptoms or cause mild to severe illness. Fever is the most common symptom in all three types of disease and lasts about 3-7 days. Other symptoms differ between the three types of disease.
There is no specific treatment, cure, or vaccine for hantavirus infection. However, we do know that if infected individuals are recognized early and receive medical care in an intensive care unit, they may do better.
As of the end of 2020*, 833 cases of hantavirus disease were reported in the United States since surveillance began in 1993. These were all laboratory-confirmed cases and included HPS and non-pulmonary hantavirus infection.
Anyone who comes into contact with rodents that carry hantavirus is at risk of HPS. Rodent infestation in and around the home remains the primary risk for hantavirus exposure. Even healthy individuals are at risk for HPS infection if exposed to the virus.
Other common Oregon rodents such as the Norway rat, roof rat, house mouse and domesticated rats and mice do not spread Hantavirus. If you think you may have been exposed to deer mice and become sick, seek medical attention immediately.
Don't touch mouse droppings with your bare hands. Instead, put on a long-sleeve shirt, protective gloves, and a mask. When you're done cleaning, remove the gloves and wash your hands and clothes thoroughly with soap and warm water. Spray contaminated surfaces with a bleach-based or household disinfectant.
How should residents properly get rid of rat or mouse droppings and other rodent evidence? including feces, urine and nesting material. When these substances are swept or vacuumed they can break up, forcing virus particles into the air where they can easily be inhaled, infecting the person doing the cleaning.
Typically an N95-rated Dust Mask is considered sufficient protection against viruses. Particles from mouse feces might become airborne if they are swept or vacuumed, so spraying with a mixture of bleach and water is recommended before wiping down the areas.
What can make hantaviruses so harmful to the people who get them? People who have HPS may be prone to respiratory failure. Respiratory failure can be fatal as well. If an individual who has HPS is able to get past respiratory failure, he or she may require several weeks to heal 100 percent.
Early symptoms include fatigue, fever and muscle aches, especially in the large muscle groups—thighs, hips, back, and sometimes shoulders. These symptoms are universal. There may also be headaches, dizziness, chills, and abdominal problems, such as nausea, vomiting, diarrhea, and abdominal pain.
Doctors diagnose hantavirus with several tests. Blood tests identify proteins (antibodies) associated with the virus. Blood tests can also reveal signs of the disease. These signs may include larger-than-normal white blood cells and an abnormally low amount of platelets (a substance that helps blood clot).
Do not sweep with a broom. Use a mop, a mop bucket, and ammonia solution (1:10 dilution of bleach or ammonia or 3% Lysol solution). Alternatively, Hantavirus is killed by direct exposure to sunlight (>30 min) or heat (> 60 degrees C).
How can you tell if rodent droppings are old or new? Fresh droppings are a brighter black color and moist to the touch. Older droppings are often faded and will crumble become pulverized. Droppings as fresh as 48 to 72 hours will start to look faded and old.
What are the symptoms of Hantavirus Pulmonary Syndrome? Symptoms begin one to eight weeks after inhaling the virus and typically start with 3-5 days of illness including fever, sore muscles, headaches, nausea, vomiting, and fatigue. As the disease gets worse, it causes shortness of breath due to fluid filled lungs.
Survival of the virus for 2 or 3 days has been shown at normal room temperature. Exposure to sunlight will decrease the time of viability, and freezing temperatures will actually increase the time that the virus survives.
