The Dangers Fleabites and The Disease

Essentially11, the major discomfort as a result of the presence of fleas is their bite as well as the intense itching that this brings about. Normally, the itchiness and red bite mark gradually vanish without any long-term effects to your health. However, there are dangers of flea bites, especially when the fleas are infected themselves.

But, because fleas are disease and parasite vectors and can cause severe allergic reactions in people or pets who are very sensitive, it is essential to know about the different possible diseases they can transmit.

Diseases Transmitted By Fleas



Fleas can infect you and your animals with different diseases. Dependent on the seriousness of the infection, it can have a minor to a serious effect on you or your pet. The commonest symptoms are itching and hair loss. But the dangers of flea bites must never be underestimated.


In addition, fleas can be the carriers of the dog-cucumber core tapeworm – Dipylidium caninum (20-40 cm long). The eggs could be picked up by the flea larvae. These grow in the adult flea to the Finn. When the fin-bearing flea is bitten and consumed by a cat or a dog, the levels of development enter the intestine of the animal and develop into a tapeworm. Occasionally, humans are affected. A list of likely diseases that can be transmitted by flea bites can be found below.


Fleas are not uncommon as well as intermediate hosts for tapeworms. Because the eggs of the tapeworm are taken up by flea larvae. And when treating the fur of dogs and cats with the tongue, a flea infected with this tapeworm can enter the intestine. If the worm eggs then settle on the intestinal mucosa of the dog or cat, the eggs develop within 20 days to a full-grown tapeworm, which is on average ten to 70 centimeters long and two to three millimeters wide. By contact with other dogs and cats, a tapeworm, as in the transmission of fleas, other animals can attack.

To counter or prevent this, a regular worm cure is very effective. This treatment should be performed once a month for particularly endangered animals. Because the unpleasant “lodgers” can accompany dog and cat otherwise a lifetime! Corresponding preparations, depending on the species, breed, and age, are available from the vet. As a rule, a worming cure for animals is also very well tolerated.

Special attention should be given to this topic when small children are in the household. Even though tapeworms usually only attack animals and very rarely humans, it can happen that children come into contact with the parasites if they inadvertently swallow fragments of the infected fleas.


Dangerous meningitis also referred to as meningitis, is among many diseases that can be caused by a flea bite. Meningitis is an infectious disease that is largely transmitted by viruses or fungi. Furthermore, infection by bacteria – such as Borrelia – likely. Flea stings are usually the portal of entry for the dangerous germs. The destructive thing about meningitis is that in many animals this disease originally has no clear symptoms.

Only in the advanced level of inflammation can the loss of appetite, apathy and high fever occur. Likewise painful inflammation of the joints and limbs along with movement disorder and remarkable behavioral disturbances can be the cause of Lyme disease in infected animals.

If these signs are not observed, and no veterinarian is visited, this will also damage the internal organs – kidneys and heart – in the further process the disease. Additionally, nerve inflammation, allergic reaction in the back and severe dermatitis with aqueous exudations follow.

Consequently, it is necessary to see a veterinarian quickly if any of the above symptoms arise. The treatment of meningitis is done by antibiotics over a period of a minimum of two weeks.

Flea Allergy

Many animals may be allergic to flea saliva. Sensitive four-legged friends have a single flea stitch to trigger a flea allergy. It has this allergy between the flea saliva and the proteins in the animal skin to a reaction. Flea allergic reaction, also called flea allergy dermatitis (FAD), flea allergy, flea-spit allergy or flea-sting hypersensitivity, is normally related to severe itching. The associated scratching not uncommon results in purulent skin inflammation, hair loss and crusting in the back of the animals (see picture at Wikipedia). Typical of a flea allergy are associated symptoms like apathy or weakness. A highly effective treatment for a flea allergy are spot-on preparations whose dynamic elements are really uncomfortable to the foot organs of the parasites. Therefore, the fleas no longer bite the host animal and take flight.

Typhus Fever

Another infectious disease is typhus fever. It is equally known as lice fever, lice fever and putrefaction and was initially known as typhus. About the puncture site of an infected flea, the virus will also transfer to dogs and cats. If a four-legged friend has been affected with typhus fever, you will find a blue-black color and an intense itching at the injection site. Other signs and symptoms can include fever, headache, body aches and exacerbated consciousness, particularly in extreme cases. For Central Europe, but, the chance of infection is quite minimal, as typhus fever mainly occurs in the tropics and subtropics. If the typhus fever in this country but once found by a vet typhus in a pet,

Dermatitis And Hair Loss

When an animal is infested with fleas, the regularly unpleasant flea-bites cause the four-legged friends always scratching and biting. And this scratching and biting will cause skin inflammation and also hair loss. Especially obvious are the inflammations at the base of the tail. However, they can also appear in other parts of the body of the animals. If an animal is suffering from skin inflammation and hair loss, it is important to consult a veterinarian at once, mainly because prescription, anti-inflammatory drugs help against the symptoms and can stop additional bacterial infections.

Bubonic plague

plague from fleasThe most well-known flea transmitted disease is the Bubonic plague. In the 14th century, the bubonic plague (often known as the “Black Death”) became an epidemic and destroyed 25 million people – up to 50% of the European population.

Right now, the plague still happens worldwide, having very few cases each year reported in the southwestern U.S. The plague is carried by rodents and transmitted to fleas that bite them, which is how it is transmitted to humans and pets. This is one of the greatest dangers of flea bites.

Fortunately, successful therapy can be accomplished by using antibiotics.

Murine Typhus

This is an unusual disease in North America, however, several cases of Murine Typhus are reported yearly and usually originating in southwestern states. This disease occurs in rat-infested areas, where fleas end up been infected by rats.

The most typical symptoms include high fever, serious headache, chills, fatigue and nausea however treatment is readily available and patients usually respond instantly.

Regrettably, pets can bring plague or murine typhus-infected fleas into the home.


This condition is hardly detected in North America however due to international travel originating from hot regions, like the West Indies, Caribbean, and Central America, where it is native, it is worth knowing about this illness.

This disease is passed on by the burrowing flea (Tunga penetrans), which is typically referred to as a chigger flea or sand flea (amongst others). It normally affects the feet, where the flea anchors itself into the skin and burrows into the epidermis. Tourists are often encouraged to wear shoes (not sandals) when walking across sandy areas in affected regions.

Flea-associated Allergies

Flea saliva can cause skin dermatitis in humans, which usually appears on patches of skin as itchy bumps. Most people can have asthmatic-type reactions when they inhale flea feces. Pets can also react to flea bites and will develop a flea hypersensitivity or flea-bite dermatitis. As a result, animals may develop crusty lesions and may always scratch at their skin, which often lead to fur loss.
