The tick season began with spring. To avoid being bitten, it is particularly necessary to avoid forts and undergrowth, wear closed clothing and apply a repellent.

Ticks are particularly active from March to November. Every year, the insurance covers about 10,000 cases of fangs that cause costs worth 11.6 million francs, said Suva Monday.

A tick bite can cause borreliosis, also known as Lyme disease. Depending on the region, 50% of ticks carry this bactria. There is no vaccine against this disease that can be treated with antibiotics.

Variable evolution

The disease can evolve very variable. Often the infection goes unnoticed. The tick bite can lead to the appearance of flu symptoms, which disappear within a few weeks, but it takes several months for the rash to be absorbed, Suva says.

Several weeks or months after the puncture, lysations of the nervous system may occur in the form of pain, sensory disturbances and paralysis of the arms, legs and head. Heart problems are rare.

Meningo-encephalitis ticks

The sting can also cause a shameful encephalitis, ie an inflammation of the brain and brain. This disease is caused by a virus. Ticks carry this virus only in certain regions.

The evolution of the disease can be serious: squalling and permanent deaths are possible. There is a vaccine against encephalitis ticks, but antibiotics are ineffective.

Two cases of meningo-encephalitis were recorded during the month of March of this year. In 2018, 323 cases were registered in Switzerland, according to the Federal Office of Public Health. There were 191 cases in 2017.
