Flea Bite Symptoms You Should Never Ignore

Even if the flea bites are harmless, and usually flea bite marks go away on its own, you should be aware that some people are allergic to flea bites. If you are one of those people, you may have an allergic reaction to flea bites.

Scratching the flea bites marks is another problem because our fingers are dirty. If you tear the skin, then there is a high chance that bacteria will get inside your body and make an infection. Do not scratch flea bites.

Most common flea bites occur on human legs. There is also a chance that you will get flea bites on hands and even face if your pet is infested with fleas. We all love to cuddle our pets, and if they are infected with insects, there is a high chance of getting flea bites on face.

Do Flea Bites Itch?

Trust me, you will know if you get flea bites. Flea bite on its own is not painful, and it doesn’t even itch. But once the flea starts drinking blood, it will release flea saliva. Flea saliva is irritating the host. Humans, as well as pets, will immediately begin to scratching as soon saliva touches the skin. Flea saliva is the main reason why flea bites itch.

In other words, when you get flea bites, you will have an enormous urge to scratch. But don’t scratch because that can create infections, which can be extremely dangerous.

Flea bites itch will go away in a day or two, but if you had an allergic reaction, then flea bites can turn to skin rash, and that kind of skin rash may itch for weeks. Also, the itching will last longer if there is an infection, so the best thing you can do is not to scratch and avoid infection at all costs.

Flea Bite Allergy

Nowadays, people are getting allergic reactions to many things. However, flea saliva is one of the substances that can develop allergic reactions in humans. These reactions can be seen as skin rash, extreme itching, and even swelling. If you have an allergic reaction, then there is also a higher chance of infection because rash will force you to itch, and there is a high chance you will itch.

Many people don’t know if they are allergic to flea bites, and that’s a good thing because the best treatment is to avoid flea bites. People who are constantly attacked with flea bites have a higher chance of developing an allergic reaction to flea bites.

In rare cases, an allergic reaction can be severe and even cause difficulty breathing, nausea, and swelling. If you see any of the mentioned symptoms, then you should immediately look for a doctor.

Flea bites infection is mostly caused by scratching. This infection needs to be treated, but fleas are well-known carriers of many human diseases.

Bubonic Plague

That was one of the most massive epidemics in human history. Today this disease is under control, and even if you get infected, treatment is done with antibiotics.

Murine Typhus

If flea becomes infected by rats, then murine typhus is possible. This is a rare disease only found in areas with infected rats. If you have symptoms like chills, weakness, nausea, high fever, and severe headache, then you could be infected with Murine Typhus. Patients who receive treatment respond fast, and there are no significant problems after that.

Tungiasis

Sand flea is the carrier of tungiasis, which is in the USA very rare. Sand flea is mostly found in exotic places like Caribs, areas that have lots of sand which sand flea loves. The sand flea will bite you and burrow into your skin. Sound awful, so if you are visiting exotic places full of sand, wear high socks and avoid sand flea.

Tularemia
