the Sign season 2018 has reached its peak. We have up-to-date information in the news sticker:
Update of 20.08.2018: After new finds: how dangerous are the tropical sign?
As the University of Hohenheim and the Institute for Microbiology of the German Armed Forces announce in a press release, tropical species of gender sign spread Hyalomma in Germany. This year alone there have been seven finds so far.
Seven animals are not much in themselves – but there is the increased chance that the tropical ticks settle in this country and at home.
After the discovery of the tropical species of the sign of the genus, Hyalomma experts are concerned because the sign is not only much larger than the sign in this country, but they can even transmit dangerous diseases. For example, one specimen contained a dangerous bacterium, Rickettsia aeschlimannii, a known typhus fever.
Interestingly, Lyme disease or the TBE – so that the diseases can transmit the domestic sign – have not been detected in the tropical tick until now. However, the hyalomma tick is considered to be an important carrier of Crimean Congo Hmorragic fever, of Arabian Hmorragic fever and a form of tick typhus. Moreover, they are important carriers of tropical diseases of farm animals, it said in a statement from the University of Hohenheim.
Hyalomma sign: large, with striking striped legs
The sign was found on horses and sheep. "We did not expect a hyalomma sign in Germany then, so far there have been only two separate finds in the years 2015 to 2017," explains Dr Lidia Chitimia-Dobler, tick expert at the IMB. The relatively large animals with the strikingly striped legs were observed in 2018 in the area of Hanover, Osnabrck and Wetterau. The scientists suspect that they have been introduced via birds.
The warming of the climate brings us rippling ticks
This development is surprising for Prof. dr. Dr. med. Ute Mackenstedt, parasitologist at the University of Hohenheim, but not. "Because of the warming of the climate, we can expect more and more warm-growing ticks, for example, Ixodes inopinatus from the Mediterranean has spread to Denmark." The big question is in the Hyalomma species, whether they are introduced or whether the tropical sign has already been established here.
Hyalomma taps: they love the hot, dry summer
It leads the occurrence of hyalommatics in Germany in 2018 to the hot, dry summer. "These ticks prefer a lower humidity than the ticks we see, so this year the local weather is very compliant for the living conditions of this sign."
Although tropical ticks contain neither Borelliose nor TBE agents, they are anything but innocuous. According to the University of Hohenheim, both species are particularly important carriers of "Crimean Congo Hmorrhagic Fever, Arabic Hmorrhagic Fever and a form of tick typhus, as well as important carriers of tropical diseases of farm animals."
Update from 07.08.2018: More tapping by heat
Experts expect more diseases this year due to tick bites. 2018 is a year of drawing, said KKH Kaufmnnische health insurance on Tuesday in Hamburg. Mild winter, warm spring, summer – under these conditions the arachnids would multiply rapidly. "This increases the risk of tick-borne tick-borne encephalitis (TBE) or Lyme borreliosis," says Sven Seielberg, a pharmacist at KKH.
Over the last few years, the number of infected KKH insureds has decreased slightly and in 2017 there were 1,326 Lyme disease and 197 cases of FSME across the country. Now the figures should rise again, that means. You can not be vaccinated against Lyme disease. Only clothing and tick repellants help prevent this. Lyme disease, especially in the early stages, can be treated well with antibiotics.
Against a TBE, which is transmitted by a virus and can lead to meningitis, a well-tolerated vaccine offers the only protection, so Seielberg. Bavaria, Baden-Wrttemberg, South Hesse and the south of Germany are among the risk areas in Germany. Many health insurers take the cost of the vaccine.
Update from 31.07.2018: Tickbite – when should I go to the doctor?
How dangerous sign for real? How can I protect myself from the leeches? How do I remove a check if I get bitten? Do I have to go to the doctor for a tick bite? What is the current situation in Germany – especially in the risk areas of southern Germany, particularly in Bavaria and Franconia? How does the number of tick bites and infections occur? Lyme disease or Early Meningoencephalitis (TBE)? The Robert Koch Institute has significantly more infections than in the same period in 2017. The German Red Cross rt, light clothing during walks and hikes to wear when you see ticks well.
The spring-like weather of these days invites to gardening and extensive forest walks, people and nature crave the sun. But lurk in many places where it is beautiful at the moment, again the ticking. Like all Oberfranken, Bamberg is regarded as a risk area for early meningoencephalitis (TBE). This inflammation of the meninges and central nervous system can be caused by a virus that can give off ticks when stitching with their saliva. "It is high season, but it is never too late for a vaccine against TBE, it will take three years," says Dr. Heinz-Jrgen Wagner, head of the Ministry of Health of the district administration in Bamberg.
And his office also has different cases of FSME every year. For those who work a lot in the garden or go out with the dog, director Wagner of the health care advises the TBE vaccine. Recently, Health Minister Melanie Huml (CSU) pointed out the increased number of cases of TBE in Bavaria, 234 diseases last year, in 2015 there were still 128. Huml had advised parents in particular to have their children vaccinated. According to Markus Frhwein of the Bavarian Association for Immunology, Tropical Medicine and Vaccination, three vaccinations are required within one year for full vaccine protection. From 14 days after the second vaccination, 90 percent of vaccinees already have protection.
Main danger: Lyme disease is transmitted by every fourth tick
Wagner has even tried a bit and only this weekend on his dog has discovered some of the annoying crawlies that have spelled themselves while playing in the tall grass. In addition to the TBE virus, ticks transmit a number of other diseases that have not been vaccinated. "The biggest danger is Lyme disease, which is transmitted by every fourth tick," says Wagner. He recommends careful care of clothing and body after every stay in the forest or garden. And if it suddenly tingles somewhere, you should definitely look again. Even in the pulled out trousers the parasite can survive a day, but the indoor climate usually no longer lasts. "Some ticks are smaller than a grain of rice, some soaked as thick as a pea," Wagner says.
Lyme disease: Wanderrte spreads circularly
Where ticks are detected, they must be drawn quickly. "Then you always have to see how the tick bite develops, or maybe it swells a little bit." In the case of an infection with Lyme disease, so-called pathogens of Lyme disease occur in most cases.
Starting from the crossroads, it spreads out in a circular shape. In any case, it is advisable to go to the doctor, because in the early stage, according to Wagner, borreliosis is usually treated well with antibiotics. More difficult are diagnoses and treatments of late stage borreliosis. A Wanderrte is then no longer recognizable. Many patients also do not remember tick bite because it can take longer. In later and chronic symptoms such as joint pain or facial paralysis, antibiotics are often required by Mehrwchige infusions.
Delete character: remove or rotate?
When it comes to removing ticks, there are two philosophies. Some swear to draw, others prefer to uncheck it. "I am a lot of outsiders and I have already removed 100 ticks over the years, but I prefer to shoot them instead of pulling them out," Wagner says. In any case, it is important that the tick is gripped as close as possible to the skin and not pressed on the belly. This prevents squeezing of the tick and thus the release of potentially dangerous body fluids. In addition, the tick must be removed slowly and in a controlled manner. In pharmacies there are many ways to discourage or remove ticks.
"Practical examples are tick cards that even fit in the wallet," says Carina Wohlpart of the Herzog-Max pharmacy. "If you want to turn, take a very narrow pair of tweezers or a pair of pliers, and other swaying in drawing loops." It also offers a wide range of anti-tick sprays, for the little ones the pharmacist Citronella and Kokosl.
At least a few hours, the sprays can significantly reduce the risk of ticks. Nevertheless, the control image must not be given afterwards.

Update of 30.07.2018: The perfect drawing summer
According to a report from the Institute for Microbiology of the Bundeswehr, many ticks are predicted for the summer of 2018. According to the model, 443 ticks per standardized area of 100 square meters. The highest number of ticks found since the start of the survey about ten years ago.
In comparison, in 2017 scientists found 180 ticks per standardized area. The prediction was 187. In contrast to the "ZDF", drawing expert Gerhard Dobler (Institute for Microbiology) said: "The May and June figures show us that we are right again this year."
The results of the research are generated by the largest collection of data about ticks and the associated TBE virus. The database is the result of the collaboration of the Munich researchers with the University of Vienna. The studies of the Munich scientists draw their monthly data from a surface in the district of Amberg (Oberpfalz). Every month they collect different signs and evaluate their situation.
The results of the database meanwhile show that there were many tick larvae in 2017 that could develop into nymphs in the autumn. The mild winter of 2017/2018 caused many of the leeches to survive.
Update from 21.07.2018: number of cases of Lyme disease also in Bavaria on Hchststand
The number of borreliosis cases in Bavaria caused by tick bites has risen to a high level this year. So far, nearly 2,200 cases of Lyme disease have been reported in the Free State, as spokeswoman for the state health agency (LGL), announced in Erlangen. This is the highest number of reported cases since the introduction of the registration obligation in 2013. It is about ten percent higher than in 2016 – the year with the highest number ever reported. In the comparative period in 2017 there were about 1500 reported diseases. Whether the current number moves within the usual fluctuations, the spokeswoman could not yet say.
One of the possible reasons for the increase is the good weather: when many people are in nature and at the same time the sign finds favorable conditions, there are also more tick bites. And the more animals infected with the virus, the more likely it is to transfer it to people. The data that up to now were available from Germany, according to State State, however, no indication for an increase in the degree of infection of ticks at Borrelia. About 5 to 35 percent of ticks are infected with Borrelia, according to LGL.
Update from 20.07.2018: 2018 is "one tap year" – more tick bites and infections
The number of Lyme disorders and TBE infections in Germany is increasing. Since the end of June, the Robert Koch Institute (RKI) 1292 Lyme infection reported. In 2017 there were 920 in the same period.
More Lyme disease and TBE infections than last year
at TBE there were 120 reported infections across the country since late June, mainly from southern Germany. In 2017 there were 89 cases in the same period. There is a vaccine against FSME; a later treatment of the virus infection is, however, difficult.
In Germany there is a risk of a TBE infection, especially in Bavaria and Baden-Wrttemberg, in the south of Hesse and in the south of Thuringia. Currently, a total of 156 provinces are considered as a risk area.
"The highest number of ticks in the past ten years"
2018 is a ticking year for the German Center for Infection Research (DZFI). "We have the most ticks in the last decade", predicted expert Gerhard Dobler. There is also a higher risk of meningitis (TBE) or Lyme disease. About every fourth tick carries pathogens of Lyme disease.
Update from 11.07.2018: How big is the risk of infection?
According to experts, around 2017 occurred 85 percent of all TBE infections in southern Germany (in Bavaria and Baden-Wrttemberg). As a rule, TBE is transferred to people by means of tick bites. According to experts, the disease reaches 100 to 100 people who are bitten by an infected tick.
The development varies considerably from region to region, the experts reported, for example the number of TBE infections fell in Lower Franconia in 2017, while in some Alpine regions the number of TBE infections clearly decreased. One reason can be the weather. In general, the number of TBE infections varies between 250 and 500 per year.
New transmission path of FSME by cow's milk
Relatively new is the transmission path of FSME Raw milk from contaminated grazing animals, In 2016, a case was in the news when two people were infected with goat's raw milk. In 2017, eight such cases have already been registered.
