How common is hantavirus in the US?

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.

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.

How many people get hantavirus in the US?

Reported Cases of Hantavirus Pulmonary Syndrome in the United States. As of the end of 2020*, 833 cases of hantavirus disease were reported in the United States since surveillance began in 1993.

Where is the 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.

Do all mice carry the 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 do you have to be exposed to hantavirus?

However, on the basis of limited information, it appears that symptoms may develop between 1 and 8 weeks after exposure to fresh urine, droppings, or saliva of infected rodents.

Can you have hantavirus and not know it?

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.

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.

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.

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.

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.

Is hantavirus rare in the US?

Hantavirus pulmonary syndrome is a severe respiratory disease caused by hantavirus. 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.

How long is hantavirus active in mouse droppings?

Hantaviruses have been shown to be viable in the environment for 2 to 3 days at normal room temperature. The ultraviolet rays in sunlight kill hantaviruses. PREVENTION Rodent control in and around the home remains the primary strategy for preventing hantavirus infection.

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 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.

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 to do if you think you've been exposed to hantavirus?

The sooner people with hantavirus infection get intensive care, the better their chances of survival. Those who get care only when they can barely breathe do worst. If you've had a rodent exposure and get any of the early symptoms, contact your health care professional immediately.

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.

How does hantavirus harm if not treated?

This failure causes very low blood pressure (“shock”) as oxygen is not available to all the cells of the body. This can rapidly lead to the failure of most or all of the organs and can quickly lead to death.

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.

Should you wear a mask when cleaning rat droppings?

It's a good idea to wear a mask when cleaning up rat droppings as well, because rat droppings can transmit diseases to humans. Spray the droppings and urine with disinfectant or with a mixture of one part bleach to nine parts water. Let the droppings soak for five minutes.

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.

Is hantavirus permanent?

Rodents can shed hantaviruses in saliva, feces and urine. Transplacental transmission does not seem to occur. Infected animals can carry hantaviruses for weeks to years, and they may remain infected for their entire life.

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®).
