Tick: the symptoms

We have detailed the symptoms of Lyme disease and tick-borne encephalitis.

1 - Lyme disease

Lyme disease is caused by the bacterium Borrelia burgdorferi. This condition is especially not reflected in joint symptoms. One or more joints may be affected. Joint damage is manifested by arthritis (inflammation), in the form of recurrent relapses. Lyme disease can become chronic and complicated by neurological and cardiac symptoms.

Any tick bite is not infective, and a person who is bitten by a tick is unlikely to catch this disease. Firstly because not all ticks are infected, and an infected tick does not necessarily transmit Lyme disease.

2 - Tick encephalitis

Ticks are also likely to transmit meningoencephalitis. It is due to the multiplication of the virus - of the flavivirus family - transmitted by the tick in the nervous system. After an incubation period of about 15 days, the patient suffers from symptoms such as chills, fever, etc. Then neurological symptoms manifest themselves: prostration, tone disorders, paralysis. The risk of death is quite high. In case of cure, neurological sequelae are frequent.

This condition is mainly prevalent in Central Europe, but also in parts of southern Scandinavia. There is a vaccine against this disease.
