What states have had hantavirus?

Hantavirus disease surveillance in the United States began in 1993 during an outbreak of severe respiratory illness in the Four Corners region – the area where Arizona, Colorado, New Mexico, and Utah meet.

How common is hantavirus in the USA?

The virus is spread to humans through contact (via inhalation or ingestion) with rodent droppings, urine, or saliva. Only 20 to 40 cases of HPS occur in the United States each year, but the syndrome can be fatal.

Where is hantavirus most common?

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.

How likely is it to get the hantavirus?

Hantavirus infections are rare. Sporadic (single) cases may occur throughout the country, but most, greater than 90%, of the cases have occurred in the west of the Mississippi River.

Does N95 mask protect against hantavirus?

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.

Hantaviruses

How long does hantavirus live in old droppings?

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.

Would I know if I had hantavirus?

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.

Does everyone exposed to hantavirus get sick?

People at Risk for 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.

Can you survive hantavirus?

Previous observations of patients that develop HPS from New World Hantaviruses recover completely. No chronic infection has been detected in humans. Some patients have experienced longer than expected recovery times, but the virus has not been shown to leave lasting effects on the patient.

Who is most at risk for hantavirus?

Anyone who comes into contact with rodents that carry hantaviruses 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.

Does Lysol disinfect mouse droppings?

A mixture of 1½ cups of bleach or Lysol® in a gallon of water is effective at killing the virus. Allow the solution to sit for 15 minutes before cleaning up with a mop or sponge. Spray rodent carcasses, nests, droppings, and other potentially contaminated items and surfaces with bleach or disinfectant.

What percentage of mice carry the hantavirus?

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.

Can you get sick from old mouse droppings?

Mouse droppings can harbor bacteria and viruses that can cause various kinds of sicknesses in humans. Several of these illnesses may be serious or even deadly for some people.

How long does hantavirus stay in the air?

It causes a rare but serious lung disease called hantavirus pulmonary syndrome (HPS). The virus does not remain active for long once outside of its host -- less than 1 week outdoors and a few hours when exposed to direct sunlight.

How do they test for hantavirus in humans?

CDC uses an enzyme-linked immunosorbent assay (ELISA) to detect IgM antibodies to SNV and to diagnose acute infections with other hantaviruses. This assay is also available in some state health laboratories. An IgG test is used in conjunction with the IgM-capture test.

Can you have a mild case of hantavirus?

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.

Should I get tested for hantavirus?

Who should be tested for hantavirus infection? Because early symptoms of hantavirus infection are vague and similar to those of the flu (ie, fever, fatigue, muscle aches), testing should be performed only for symptomatic individuals who also have a history of rodent exposure.

What happens if you accidentally vacuum mouse droppings?

Diseases are mainly spread to people from rodents when they breathe in contaminated air. CDC recommends that you NOT vacuum or sweep rodent urine, droppings, or nesting materials. These actions can cause tiny droplets containing viruses to get into the air.

What disinfectant kills hantavirus?

The hantavirus is destroyed by detergents and readily available disinfectants such as diluted household bleach or products containing phenol (e.g., Lysol®).

Do all mouse droppings have hantavirus?

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.

How long is hantavirus active on surfaces?

The virus may remain infectious for 2 to 3 days at room temperature. Exposure to sunlight will decrease the time of viability and freezing temperatures will increase the time that the virus remains infectious.

Will HEPA filter remove hantavirus?

Since hantavirus infection is acquired primarily by inhaling rodent contaminants, protection of the individual's breathing zone is the first line of defense against disease. Wearing a respirator with N-100 (HEPA) cartridges will stop particulates containing virus from entering the airway.

How common is it for mice to carry diseases?

Rats and mice are known to spread many diseases worldwide. These diseases can spread to people directly, through handling of rodents; contact with rodent feces, urine, or saliva (such as through breathing in air or eating food that is contaminated with rodent waste); or rodent bites.

How long does mouse poop stay toxic?

Typically, the hantavirus found in mouse droppings can live for about one week outside of the host. This time is cut to just a few hours when met with direct sunlight. No matter how long these droppings are dangerous, though, it is super important to clean them up the right way.
