CDC recommends you NOT vacuum (even vacuums with a HEPA filter) or sweep rodent urine, droppings, or nesting materials. These actions can cause tiny droplets containing viruses to get into the air.
Anyone who comes into contact with infected rodent droppings, urine, saliva, nesting materials, or particles from these, can get hantavirus disease. Exposure to poorly ventilated areas with active rodent infestations in households, is the strongest risk factor for infection.
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.
If you disturb the materials, you risk inhaling excrement particles, which may lead to hantavirus infection. How long does the hantavirus survive in feces? Its average survival lasts between two and four days, depending on the surrounding conditions.
The virus is often deadly but infection is very rare, and potential exposures occur much more often than infection, Chiu said. The virus is not spread by infected humans or by other animals.
Any man, woman, or child who is around mice or rats that carry harmful hantaviruses can get HPS. You do not have to already be sick to be at risk for HPS. Healthy people have become ill with HPS.
People who are ill with hantavirus pulmonary syndrome and do not get help quickly may die. Those that survive recover quickly, though full recovery often takes several months.
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.
Diseases Spread by Mice and Rats
Avoid touching your nose, ears, or mouth, and always wash your hands (even with protection) once you're done. Hantavirus Pulmonary Syndrome is a respiratory disease caused by stirring up air contaminated by rodent feces. (Avoid sweeping up droppings!)
Wearing rubber gloves, thoroughly soak droppings, nests and dead mice with a bleach/ water solution (one part bleach to nine parts water) or a household disinfectant. Let the bleach water solution sit on the droppings/nests/mice, for five minutes.
For those who have wondered, “can you get sick from mouse droppings?” the answer may be more alarming than you'd think. Mouse and rat poop can be very dangerous, causing illnesses that could become deadly if not treated properly. Accidentally touching rodent poop remains the easiest way to get one of these diseases.
Rats can also carry a viral disease that is released when dried feces, urine or saliva break up. That virus can be inhaled, causing respiratory illness. That's why it is so important to carefully clean up any evidence of a rat or mouse.
Safety Equipment for Pest and Rodent Control
In addition, a HEPA-equipped respirator should be used correctly. Removal of mouse droppings, nest materials and urine will require the use of protective gloves, long sleeved shirt, long pants, a hat, eye protection and a N95 or comparable face mask.
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.
However, the virus is shed continuously from them: into the droppings and urine they leave around the room, and into their saliva, which dries on anything they have chewed, such as nesting material. Out in the environment like this, the virus can live for several days.
Hantaviruses infect people when they are inhaled. If the virus reaches your lungs, it can infect the cells that line the tiny blood vessels in the lungs, causing them to become “leaky.” The leaky blood vessels allow fluid to fill the lungs making it difficult to breathe.
The hantaviruses that cause human illness in the United States cannot be transmitted from one person to another. For example, you cannot get these viruses from touching or kissing a person who has HPS or from a health care worker who has treated someone with the disease.
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.
Symptoms of hantavirus pulmonary syndrome appear within 1 to 5 weeks after exposure. The average is 2 to 4 weeks. This disease is extremely serious since about 40% of the people who get the disease die.
During clean-up, wear an appropriate, well-fitting filter mask, rubber gloves and goggles. These masks include NIOSH-approved 100 series filters, such as N100, P100, and R100 (formerly called HEPA filters), or a respirator with P100 cartridges. An N95 mask may also be used.
When to see a doctor. The signs and symptoms of hantavirus pulmonary syndrome can worsen suddenly and may quickly become life-threatening. If you have flu-like symptoms that progressively worsen over a few days, see your health care provider. Get immediate medical care if you have trouble breathing.
A 1% solution of household bleach (1:100 dilution) is an adequate surface disinfectant, which can be used for wiping down potentially contaminated surfaces. A 10% solution of bleach (1:10 dilution) is recommended for heavily soiled areas or items contaminated with rodent urine, droppings, or nesting materials.
The majority of Hantavirus infections occur in males and in individuals between the ages of 20-40 4. Trappers, hunters, forestry workers, farmers, and military personnel have a higher risk of contracting the disease 2 4.
