Virus Risk: Why Sweeping & Vacuuming Rat & Mice Droppings Can Be Hazardous to Your Health. Rats and mice are dangerous from a public health standpoint because they can transmit disease through their waste. For that reason, properly removing rodent feces and urine is very important.
People get HPS when they breath in hantaviruses. This can happen when rodent urine and droppings that contain a hantavirus are stirred up into the air. People can also become infected when they touch mouse or rat urine, droppings, or nesting materials that contain the virus and then touch their eyes, nose, or mouth.
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 have been exposed to fresh mouse droppings, there's a possibility that within 1 to 8 weeks you will develop Hantavirus symptoms, such as: Fever; Muscle pain, especially in the hips, thighs, and back; Fatigue.
Mouse droppings carry and can transmit several harmful diseases. Two of the most common illnesses are Hantavirus Pulmonary Syndrome and Salmonella. Hantavirus Pulmonary Syndrome (HPS) – This disease is particularly dangerous because it not only spreads through direct contact with rodent feces but also through the air.
Rats and mice carry two main types of disease in their waste: Salmonellosis and Leptospirosis. Salmonellosis is a type of food poisoning.
The risk of acquiring hantavirus is extremely rare, even among people who are consistently exposed to mice and other rodents. The majority of exposures (70%) occur around the home. Hantavirus poses no significant health risk to WSU employees provided that simple precautions are followed.
Can I Get Hantavirus From Old Mouse Droppings? The short answer is yes. But, it is very unlikely. There are typically less than five cases of Hantavirus reported each year, making it highly unlikely that you will contract this disease.
Native Australian rodents (for example Hopping Mice) pose little or no threat to public health and should be left alone as they are protected species. However introduced rodents may infest residential and agricultural areas and carry disease.
In most recorded cases, symptoms develop 1 to 8 weeks after exposure. Early symptoms, such as fever, dry cough, body aches, headaches, diarrhea and abdominal pain, are similar to many other viral illnesses.
Hantavirus: Once thought to be rare this disease has been identified in rodents across Australia.
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.
Diseases are mainly spread to people from rodents when they breathe in contaminated air. 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.
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.
Bites and direct contact through broken skin can also cause an infection. Approximately 5 percent of common house mice carry the lymphocytic choriomeningitis virus, but even other domesticated rodents, such as hamsters, can become carriers due to being infected by wild mice.
House mice do not carry hantavirus. Other wild mice, like deer mice, can vector hantavirus, but are most often found in rural areas, the desert, and mountains and rarely invade inhabited human homes.
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.
Every year, there are approximately 300 cases reported in the Americas. Hantavirus infections can be fatal. Fatality rates may reach up to 60%. There is no available treatment.
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.
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.
Hantavirus is a severe, potentially fatal, illness. Humans can be exposed to Hantavirus when the urine or feces of an infected rodent become airborne. This means that anyone who disturbs areas of mice or mice droppings, such as when cleaning, can be at risk.
According to the National Pest Management Association, a mouse produces between 40 to 100 droppings per day, while a rat produces between 20 to 50 droppings. Mouse droppings are best described as small, pellet-shaped and dark brown in color with pointed ends. Mice droppings are typically small, about ¼-inch in length.
There are two main things that can attract mice and rats to your house – food and shelter. If you don't tidy up properly and there's food waste on the floor or surfaces, rodents are going to love it! Rats and mice also need shelter, particularly during winter to avoid the worst of the cold.
Health Hazards Posed by House Mice
House mice may be cute and cuddly, but they are a real health hazard. Their feces and saliva can spread bacteria, contaminate food sources, and give you allergic reactions. Their dry fecal matter can be harmful if breathed in.
