The hyalomma tick is larger than the common bushbuck.

In Germany, single copies of the tropical tick Hyalomma were found for the first time. Until now, the only type of sign known in this country was the common bushbuck and the Ragwort. The Hyalomma finch is five times larger than the common bushbuck, the legs are strikingly striped, it can run quickly and passes on diseases that can lead to death. After a Report on tropical giant sign in Lower Saxony, many people have sent copies for research on the researchers at the Robert Koch Institute in Berlin. The Hyalomma had been sucked on horses.

How hyalomma ticks spread in Germany

Hyalommatikken are so-called hunting signs. They have eyes with which they can see well, run quickly to their victims and can follow them over a distance of 100 meters.

They mainly live in Africa and Asia, but also in countries such as Turkey, Kosovo and parts of Spain. After Germany the gigantic tick comes in two ways:

  • by migratory birdsThe tick slides off the host when it is shunned a second time. Usually it is not warm enough, the tick dies. But the summer heat left the hyalomma alive and looking for new hosts: horses, sheep, cattle and people.
  • by vacationerBecause many Germans spend their holidays in Turkey and Spain, infected ticks can come to Germany or infect a person on holiday.

According to experts, hyalomma ticks will die in Germany as soon as the weather gets cooler in Germany. Whether the tropical species of sign can establish themselves in Germany will only become clear in the coming years.

Typhoid fever and Crimean Congo fever due to Hyalomma tick

All ticks can transmit diseases. Each type of tick is specialized in certain pathogens. In the Hyalomma research in Germany until now scientists found a bacterium, the spot typhus can activate. This disease works well with antibiotics.

But tropical medicine knows Hyalomma mainly as a carrier of the often fatal Crimean Congo feverIn addition to fever, extensive bleeding occurs in the arms and legs. Often, the infected people die due to internal bleeding. There are already several deaths in Turkey and in Spain two people have already died in Crimea Congo.

The hyalomma found in Germany so far do not have the dangerous Crimean Congo virus. Researchers want to see the kind of sign, but see no reason for panic.

Prevent Crimean Congo fever after tick bite

Anyone stung by a tick in Turkey or another affected area should immediately go to the doctor. In the first few hours after a tick bite you still have good chances to treat the Crimean Congo virus with a medicine. Once the bleeding has broken out, the chances of survival are small.

Domestic ticks transmit Lyme disease

Even domestic signs such as the common bushbuck and Auwaldzecke can transmit diseases, especially in the north Disease. Bacteria that are related to the cause of syphilis enter the skin through the wound and spread through the blood through the body. From there they can enter the joints, the heart or the nervous system.

Protection against tick bites

Protection against tick bites offers long, closed clothing: trouser legs are stuck in the socks! Tick ​​spray can also keep the animals away: certain smells (repellents) keep ticks away by their smell. They are applied to the skin and provide some protection for a few hours. If you have been put in despite all the protective measures, remove the tick as soon as possible.

Up to 30 percent of the ticks have Borreliosis pathogens and can transmit them to people. Early recognized, the disease is good to treat.
