With the advent of warm days we wear fewer and fewer clothes and we go for a walk to the forest or a meadow, where unfortunately there are ticks waiting for us, among others. Sometimes one bite is enough to get infected with borreliosis. It is caused by bacteria that belong to the vertebral column. Lyme disease is the best known tick-borne disease, which does not always manifest itself in the characteristic migratory erythema. Sometimes only skin lesions occur, and the patient only learns about Borrelia at a late stage of the disease.

How do we know the first symptoms of tick bite and what action should be taken after a diagnosis of erythema after a tick bite?

What does borreliosis manifest?

After a tick bite, various symptoms may appear. Within a few to a dozen or so days, migrating erythema can be observed if you have been bitten by a tick infected with Borrelia. The erythema usually disappears spontaneously within a month, but can stay longer. This indicates that the vertebral column has spread and that Lyme borreliosis has passed from the cutaneous to the early disseminated form. This erythema can be recognized by the fact that there is a spot in the centre after the bite of the parasite, followed by a pale circle, closed by a red rim, which moves further and further every day and grows. The diameter of the erythema is at least 5 mm. This is usually accompanied by flu-like symptoms (fever, sore throat, chills, headaches, muscle tics, joint stiffness, joint pains). However, we have to reckon with the fact that only some people develop erythema.

If we have been bitten by a tick, but no erythema has occurred, there is no certainty that we have not been infected with borreliosis. Untreated Lyme disease can lead to very serious neurological, arthritic and cardiac complications.

What to do in case of erythema after a tick bite?

In case of erythema on the skin after a tick bite, it is necessary to see a doctor immediately. If possible, take the stretched tick with you to test for Borreli.
