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.
Due to the small number of HPS cases, the “incubation time” is not positively known. 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.
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.
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.
Rats and mice carry two main types of disease in their waste: Salmonellosis and Leptospirosis. Salmonellosis is a type of food poisoning.
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.
Do not use a vacuum or a high-pressure sprayer on rodent urine, droppings, or contaminated surfaces until they have been disinfected. Spray materials with a disinfectant until fully soaked and let sit for 5 minutes or according to label instructions.
Rat Poop Carries Hantaviruses
“Old World” strains of hantavirus — those found in the Eastern Hemisphere — may cause diseases like hemorrhagic fever with renal syndrome.
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.
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.
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.
The hantavirus is destroyed by detergents and readily available disinfectants such as diluted household bleach or products containing phenol (e.g., Lysol®). Choose an agent that is compatible with the item, object or area to be cleaned and disinfected.
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.
Mice droppings are typically small, about ¼-inch in length. You can tell if they are fresh droppings by the color. Newer droppings will be darker and shinier while older droppings will look chalky and dry. Rat droppings are similar in shape but larger, typically ½-inch to ¾-inch in length with blunt ends.
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.
Allow a week to pass before you begin to remove rat fecal matter. Waiting will allow enough time for any infectious viruses in the rodent's urine, droppings or nesting material is no longer infectious. Before you begin cleaning, ventilate the space by opening doors and windows for at least 30 minutes.
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.
The smell of a dead rat can be harmful to a person's health due to the toxic gases and microscopic compounds of the dead animal that are constantly being released into the indoor air. Since most homes are not consistently ventilated, the gases permeate into the respiratory tract and can potentially cause illness.
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.
Surfaces infested by mice should be thoroughly cleaned and disinfected. Dampen the urine, droppings and nesting materials with a commercial disinfectant or a mixture of bleach and water (1 part bleach to 9 parts water) and let soak at least 5 minutes.
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.
As it turns out, there are several smells that these pests cannot stand, which means you can use them to your advantage. But what exactly do mice and rats hate to smell? Mice can be kept away by using the smells of peppermint oil, cinnamon, vinegar, citronella, ammonia, bleach, and mothballs.
Mice are known to carry diseases such as salmonella and hantavirus that can potentially be serious for humans. Furthermore, the fleas and ticks that live on mice can transmit illnesses to humans such as Lyme disease. And, as tiny as they might be, mice can cause big problems when they infest a home.
Rodents can carry dangerous pathogens, like hantavirus. Hantaviruses are a family of viruses found worldwide. In the United States, deer mice and other wild rodents can shed hantavirus in their urine, droppings, and saliva. People can become infected when they breathe in contaminated air.
