3 Potentially Deadly Diseases Caused By Bats

Nuisance bats are nuisances for very good, and frightening, reasons. For one, they are highly destructive, and can cause extensive structural damages to homes, buildings, barns, and more. These damages are not only tedious to reverse, but also very costly. However, the threat of structural damage is not the key reason why bats are not something you want around your property. The biggest threat they pose is disease and illness. Bats are common carriers of several infectious and parasitic diseases, some of which are potentially deadly to both people and pets.

Rabies Virus

The most widely known disease associated with bats is the rabies virus.  Rabies is a very serious illness that is easily spread through bodily fluids, like urine or saliva. There is no cure or treatment for Rabies once it is contracted, making it 100% fatal. For this reason, pet vaccinations are crucial. In fact, the Kentucky Administrative Code statute states that all dogs, cats, and ferrets must be vaccinated at 4 months of age, and then re-vaccinated annually by a licensed and accredited veterinarian. If a bat were to bite a person, it is possible for that person to contract the Rabies virus. In this case, they would require immediate medical attention involving a series of injections, medications, and treatments. But before the vaccine was invented in the 1900’s, all cases of rabies in humans were fatal. 


Histoplasmosis is an infectious disease that is contracted as a result of being exposure to bat droppings (guano) over a long period of time. A fungus that grows in guano called Histoplasmosis Capsulatum produces spores will travel through ductwork and into the living or trafficked areas of a property, thus exposing people and pets without any knowledge. The inhalation of these spores can cause flu-like symptoms, such as coughing and difficulty breathing. Fortunately, there is a treatment for Histoplasmosis, as well as vaccines for pets. However, the disease can turn deadly for those with existing medical conditions or suppressed immune systems, as well as for infants and elderly folk.

Fibrosing Mediastinitus

If a person is ill with Histoplasmosis, they may experience a very rare complication of the disease called Fibrosing Mediastinitus. In contrast to the symptoms of Histoplasmosis, Fibrosing Mediastinitus will cause serious complications that can lead to death. The disease essentially constricts the heart and lungs from functioning. Without immediate treatment, it can be fatal. Although very rare, it is a terrible and painful disease for those infected.
