In addition, there are no reports of hantavirus infection in humans in Australia. Hantaviruses routinely establish persistent, non-cytolytic infections in rodent hosts and are maintained in the wild by rodent reservoirs.
Abstract. Hantavirus antibody-positive rodents have been found across Australia although, to date, there are no reports of infections in humans.
Mice can contaminate food — which can lead to food poisoning and spoilage. Rampant rodents can also carry diseases that may spread to humans.
Hantavirus: Once thought to be rare this disease has been identified in rodents across Australia. This serious and potentially fatal disease is spread through inhalation of dust that contains urine, saliva, or droppings. Direct infection from bites is also possible.
They carry and transmit many diseases found in Australia including Murine typhus fever, Rat-bite fever, Weil's disease and Lymphocytic choriomeningitis.
Mouse plagues occur in southern and eastern Australia, usually in the grain-growing regions, around every four years. Aggregating around food sources during plagues, mice can reach a density of up to 3,000 per hectare (1,200/acre).
CSIRO mouse researcher Steve Henry says farmers have reported increased mice numbers in northern NSW, central Queensland, north-west Victoria and South Australia's Yorke Peninsula. But the wheat belt of Western Australia has been worst hit.
Introduced rodents can: Carry diseases such as leptospirosis and typhus fever. Contaminate food with their hair, droppings and urine, resulting in food poisoning and spoilage. Generate unpleasant odours.
Is the Disease Fatal? Yes. HPS can be fatal. It has a mortality rate of 38%.
The chance of being exposed to hantavirus is greatest when people work, play, or live in closed spaces where rodents are actively living. However, recent research results show that many people who have become ill with HPS were infected with the disease after continued contact with rodents and/or their droppings.
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.
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.
Mop floors and clean countertops with disinfectant or bleach solution. Steam clean or shampoo upholstered furniture and carpets with evidence of rodent exposure. Wash any bedding and clothing with laundry detergent in hot water if exposed to rodent urine or droppings.
“Orthohantavirus” - commonly known as hantavirus – is a very, very rare virus. There have never been confirmed human cases in Australia.
Although prevalence varies temporally and geographically, on average about 10% of deer mice tested throughout the range of the species show evidence of infection with SNV.
Transmission. Cases of human hantavirus infection usually occur in rural areas (forests, fields, farms, etc.), where rodents hosting the virus may be found. However, transmission may also occur in urban areas. The virus is contracted through the inhalation of rodent droppings (urine and feces) and saliva.
HPS has a mortality rate of 38%. 2. Who is at risk of contracting HPS? - Anyone who comes into contact with infected rodents or their contaminated excreta is at risk of acquiring HPS. Rodent infestation in and around the home remains the primary risk for Hantavirus exposure.
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. Other symptoms differ between the three types of disease.
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.
They can make you very sick
While the common house mouse is not as dangerous to your health as a deer mouse, they can still spread disease, such as hantavirus, salmonellosis and listeria through their urine, droppings, saliva and nesting materials.
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.
Moderate numbers of mice are a serious concern for this time of year. Urgent action is required to minimise damage and losses as crops mature. There is a short window of opportunity to act prior to harvesting. Mice will commence breeding soon, meaning numbers will increase further.
Live Science reported in March as a result of the “rampaging mice”, some farmers lost entire grain harvests “while hotels have had to close because they can't keep the critters out of the rooms.” In some places, residents of affected areas reported mice falling out from roof tops causing “mice rain”.
