What diseases do rats carry?
Rats carry many diseases that are dangerous to both humans and animals. These diseases are spread through their urine, faeces, and saliva, and by coming into contact with contaminated food or water. The transmission of these diseases to humans can occur through direct contact with rat urine, inhalation of aerosolized particles, or ingestion of contaminated substances. The diseases caused by rats can cause mild illnesses to severe infections that can be fatal if left untreated. Below are some of the most common diseases transmitted by rats.
Leptospirosis
Leptospirosis is caused by the Leptospira bacteria, which can be transmitted to humans through contact with water or soil contaminated by rat urine. This disease can enter the body through cuts, mucous membranes, or even through ingestion. Symptoms of leptospirosis include fever, chills, muscle pain, and, in severe cases, kidney failure. If untreated, this disease can lead to Weil’s disease, a more severe form of leptospirosis that affects the liver and kidneys.
Leptospirosis is commonly spread in areas where rats and other rodents exist, making pest control essential in preventing its transmission. The bacteria are often found in water contaminated by rat urine, making it vital to avoid contact with potentially contaminated water sources.
Weil’s Disease
Weil’s disease is a severe form of leptospirosis that primarily affects the liver and kidneys. It can lead to jaundice, kidney damage, and even death if not treated promptly. Weil’s disease is caused by the same bacteria as leptospirosis and is transmitted by rats through their urine. The early symptoms of Weil’s disease are similar to those of leptospirosis, but the progression of the illness can result in life-threatening complications such as organ failure.
Salmonellosis
Salmonellosis is caused by the Salmonella bacteria, which rats are known to carry. The transmission of this disease occurs when humans consume food or water contaminated by rats feaces. Symptoms of salmonellosis include diarrhoea, abdominal cramps, and fever. In severe cases, the infection can lead to dehydration, especially in vulnerable populations like the elderly or those with weakened immune systems.
To prevent the spread of salmonellosis, it’s important to maintain a clean environment, especially in areas where rats are present. Rat infestations can lead to contamination of food storage areas, making proper pest control measures critical.
Hantavirus
Hantavirus Pulmonary Syndrome (HPS) is a severe respiratory illness caused by inhaling dust contaminated by rat or mouse droppings, urine, or saliva. Symptoms of hantavirus infection include fever, cough, chest pain, and difficulty breathing. In its advanced stages, this disease can cause severe respiratory distress and, in some cases, death.
Hantavirus is typically associated with deer mice, but other rodents, including rats, can also transmit the virus. The risk of transmission increases in enclosed spaces where rodent droppings and urine may accumulate, such as storage areas and cabins.
Rat-Bite fever
Rat-bite fever is caused by a bite or scratch from a rat, although it can also be contracted by coming into contact with food or water contaminated by rat feces. Symptoms of rat-bite fever include fever, vomiting, rash, and joint pain. Without prompt treatment with antibiotics, rat-bite fever can cause serious medical complications, including heart infections.
This disease highlights the importance of avoiding direct contact with rats and maintaining proper hygiene, especially in areas where rats are present.
Plague
The plague, caused by the Yersinia pestis bacteria, is one of the most infamous diseases transmitted by rats. Historically, the plague killed millions of people during the Black Death, and it is still a concern today, although it is much rarer. Rats carry fleas that transmit the plague to humans. There are three forms: bubonic plague, pneumonic plague, and septicemic plague. Each form of the disease is dangerous, and prompt treatment with antibiotics is necessary to prevent fatalities.
While modern medicine has drastically reduced the mortality rate of the plague, it remains a dangerous disease in areas where rat infestations are not properly managed.
How rats contaminate food and water
Rats are known to contaminate food and water sources through their urine, faeces, and saliva. In addition to directly contaminating food by chewing through packaging, rats also spread bacteria and viruses via their droppings and urine. This contamination can occur in kitchens, food storage areas, and warehouses, where rats and mice may scavenge for food.
The transmission of diseases from rats to humans often occurs when food is prepared or consumed after being contaminated by rat urine or feces. Similarly, water sources can be contaminated if rats have access to drinking water or water storage tanks. In areas with high rat populations, the risk of contamination increases significantly, making pest control efforts extremely important to prevent the spread of diseases.
Direct contact with rat droppings and urine
Rats excrete urine and faeces wherever they roam, including on food preparation surfaces and in food storage areas. Humans can unknowingly come into contact with these contaminated surfaces or ingest food that has been tainted by rat droppings or urine. This is a major route of transmission for diseases like leptospirosis and salmonellosis.
Proper cleaning and sanitation are key to reducing the risk of contamination in areas prone to rat infestations. Ensuring that food is stored in sealed containers and that surfaces are regularly disinfected can help prevent the spread of rat-related diseases.
Inhalation of contaminated particles
Another way rats contaminate food and water is through the inhalation of aerosolized particles from their urine or droppings. This is particularly dangerous in enclosed spaces, where particles from rat faeces and urine can become airborne. Diseases such as hantavirus can be transmitted in this manner, making it essential to minimise exposure to areas where rats have been present.
Preventing rat-related diseases
Preventing rat-related diseases begins with effective pest control and hygiene practices. Rats must be removed from homes and businesses to avoid contamination and the transmission of diseases. Below are some preventive measures that can help reduce the risk of rat infestations and the diseases they carry:
Proper waste management
Rats are attracted to food waste and improperly stored garbage. Ensuring that trash is disposed of in sealed bins and that food waste is not left out can reduce the likelihood of attracting rats. Additionally, regularly cleaning and sanitising food preparation areas can help eliminate potential food sources for rats.
Sealing entry points
Rats can enter buildings through small gaps and cracks in walls, floors, and foundations. Sealing these entry points is a big step in preventing rat infestations. Regular inspections of your property can help identify areas where rats may be gaining access, allowing you to take action before an infestation occurs.
Maintaining cleanliness
Keeping your home or business clean is another effective way to prevent rat infestations. Regular cleaning of food storage areas, kitchens, and dining spaces can help eliminate potential food sources for rats. It is also important to ensure that food is stored in rat-proof containers to prevent contamination.

FAQS
What are the main diseases caused by rats?
Rats can carry several dangerous pathogens, making them a serious risk to human health. Rat diseases such as leptospirosis, hantavirus, and salmonellosis are caused by the bacteria found in their urine, saliva, and feces. These diseases are often transmitted to humans through direct contact with infected rodents or by inhaling aerosolized particles from contaminated environments. It’s important to recognise the symptoms, which include fever, muscle aches, and, in rare cases, more severe respiratory issues like breathing difficulty.
How can rodent diseases be transmitted to humans?
Rodent diseases are often transmitted to humans through bites and scratches, contact with infected urine, or by inhaling dust contaminated by rat faeces and saliva. Rats are known carriers of mites and ticks, which can further spread diseases such as Lyme disease. Additionally, some rodent diseases can spread through contact with mucus or by ingesting contaminated food. It’s essential to disinfect areas where rats have been present to reduce the risk of disease transmission.
What symptoms should I look for if exposed to rat diseases?
Symptoms of rat diseases vary depending on the specific illness. Common signs include fever, joint pain, nausea, and difficulty breathing. Infections like salmonella can cause diarrhoea, while others, such as hantavirus, may lead to more serious respiratory issues. If left untreated, diseases caused by rats can result in severe complications, so it’s important to seek medical help if symptoms include chest pain or trouble breathing.
How do rats contaminate food and water?
Rats can contaminate food and water through their urine, feces, and saliva. Rats are known to chew through food packaging, leaving behind harmful bacteria that can cause salmonella infection and other diseases. Water sources contaminated by rat urine can also lead to the spread of leptospirosis, a disease caused by leptospira bacteria. It’s vital to keep food stored properly and avoid leaving water sources open to rats.
Why are rodent diseases considered dangerous?
Rodent diseases are dangerous because rats can carry multiple pathogens that are responsible for more deaths globally than many other pests. Diseases such as the plague, which killed millions during historical pandemics, and hantavirus are just two examples. These diseases are not only harmful to human health but can also spread rapidly in unsanitary conditions. It’s critical to recognise the signs of a rat infestation early and take preventive measures to protect your home and health.
Can rodent diseases spread between humans?
Some rodent diseases can be transmitted from human to human, though it’s relatively rare.
