This website was created to detect, with the help of the public, the appearance of two dangerous tick species, Hyalomma marginatum, and Hyalomma rufipes in Hungary.

These ticks are not native to Hungary, their natural habitat is further south, along the Mediterranean Sea, in Africa, and the southern part of Asia. Thanks to the recent mild autumns and winters, these two species – together with many others – are now able to survive in the northern areas of Europe. Specimens have been found in Sweden, Germany, and the United Kingdom, among others. In addition to species migration enhanced by global warming, Hyalomma species are unfortunately also remarkable from another point of view, as they can carry and spread dangerous pathogens, including the virus that causes Crimean-Congo hemorrhagic fever.

To be able to prepare for newly emerging pathogens in Hungary, it is important to know the extent to which these species are present in the country, so we ask for your help: if you come across Hyalomma ticks, please let us know.

HOW TO CONTRIBUTE

How can you help in mapping the distribution of the two species in Hungary?

Primarily by submitting photos. If you think you have found a Hyalomma tick, please take the best possible photo of it. If possible, it is important to record the animal’s upper and lower sides as well.

It is especially helpful for us if we can examine a specimen that is still alive, so if you kept the tick alive, please place it in a well-sealed container (e.g. zip lock bag, medicine jar) after taking the photos and contact us via e-mail.

GOOD TO KNOW

Basic information

Hyalomma marginatum and Hyalomma rufipes are two species of ticks originally distributed in Southern Europe, Africa, and Central Asia. Their importance is given by the fact that both are capable of spreading dangerous pathogens, including the virus that causes Crimean-Congo hemorrhagic fever. These ticks, which are not characteristic of temperate climates, reach the central and northern regions of Europe with the help of migratory birds. This is also how a H. marginatum nymph specimen found on a hedgehog in 2009 could have ended up on Margit Island. The two tick species mentioned require special attention, as thanks to the mild autumns and winters of recent years, they can survive further north of their original habitat. Adult individuals have been found, for example, in Germany, Sweden, the Czech Republic and also in Hungary.

How do we recognize it

Compared to other domestic tick species, the most visible difference is the strong banding of the legs. In addition, Hyalomma species are characterized by grooves on the bottom of the upper part. They have an oval shape and are widest around the middle of their back. Their size varies depending on the sex, females are on average 5.5-6.5 mm long, and males 3.8-5.6 mm long, which makes them particularly large compared to the ticks found in our country.

How does it spread?

Migratory birds play a major role in the spread of the two species. Ticks can reach the more northern areas of Europe by feeding on birds and thus migrating with them. Spreading is facilitated by the fact that they tend to live attached to a host for quite a long time, up to 26 days. The cold autumns and winters typical in Hungary previously did not allow for the survival and eventual reproduction of the individuals introduced in this way, but thanks to the warmer autumn and winter weather experienced in the recent period, this is slowly changing.

Lifestyle

In contrast to the ambush strategy of common Hungarian ticks, the Hyalomma species hunt actively, they can even follow the selected host for several meters. Their well-developed eyes help them a lot in choosing their target. Adults are active above about 12°C, but hide when the soil temperature rises above 45°C. In addition to humans, Hyalomma species prefer to parasitize horses, cattle, and other domestic or wild ungulates, and other domestic animals such as dogs. They can also occur in huge numbers on larger host animals, in areas where the tick is native, up to 100 at a time. They especially like the area around body openings, they often occur in the anus area. Full-fed females drop to the ground after breeding and lay their eggs, the number of which can reach up to 7,000.

Why is it dangerous?

Hyalomma marginatum and Hyalomma rufipes became known primarily due to the spread of the Nairovirus species causing Crimean-Congo hemorrhagic fever in Europe. These pathogens cause problems mostly in Africa, Asia, and the Balkan region. There are occasional outbreaks of infection here, especially in people who keep animals and hunt, often due to contact with animal internal organs and blood and improperly disinfected tools. Symptoms of viral infection include joint pain, vomiting, high fever, headache, stomach and back pain, and various bleeding symptoms. 30% of patients do not survive the infection, and no preventive vaccination has yet been prepared. The virus sometimes emerges in Europe as well, causing the biggest problem in the Balkan region, primarily in Greece, Bulgaria, Albania and recently in Spain.

In addition, unfortunately, neither the tick nor the virus is unknown in our country. During a 2009 research, a nymph of Hyalomma marginatum was found on a hedgehog on Margit Island, and two adult male Hyalomma rufipes were found during another survey on cattle. Research on the Crimean-Congo hemorrhagic fever virus was carried out with rodents, and 20 of the 2,085 animals examined had the antibody against the Crimean-Congo hemorrhagic fever virus.

A recent research also confirmed that the virus is also present in the Hungarian population. In the course of this, blood samples from voluntary blood donors were tested for the presence of antibodies produced against the virus. Antibodies were detected in 10 of the 2,700 samples tested, and based on these, 0.37% of the blood donors selected for the survey had already been infected.

In addition to the Nairovirus that causes Crimean-Congo hemorrhagic fever, the Hyalomma species can also carry the bacterium Rickettsia aeschlimannii, and diseases related to this pathogen have also been detected in Europe.

FREQUENTLY ASKED QUESTIONS

What can it be confused with?

There are 20 to 23 species of ticks in Hungary, some of which parasitize on hosts that are also favored by the Hyalomma species. The distinction may not be easy at first, but the following images help with the difficulties:

Perhaps the most characteristic feature of the Hyalomma species is the clear, ring-like banding of the legs. Upon closer observation, small, longitudinal furrows on the upper border can be observed. The shape of the animal also helps to distinguish it, the individuals are oval-shaped before sucking blood and are widest in the middle of their back. In contrast to many other species, they don’t just attack from an ambush, they often actively hunt, following the selected host. They are larger and move quickly compared to native tick species in our country.

How to prevent tick bites?

Hyalomma species are most active in the warmer months of the year, from spring to the end of autumn, during this period it is important to pay close attention. Avoid areas covered with higher undergrowth, weeds, and scrub if possible. If this is not possible, for example during a hike or gardening, it is worth wearing clothing that is as closed as possible. The most important tool for prevention is the tick check, i.e. a thorough examination of the body surface of yourself and even more so of your family members.

How do I remove the tick?

With tweezers – or if you don’t have one, with your nails – grab the tick as close to the skin surface as possible and pull it out carefully but firmly.

Tick in the garden

The researchers from the Centre for Ecological Research are asking for Your help in their new project next to the Tickwatcher, called Tick in the garden. In this research, we are focusing on finding out which tick species are present in the urban gardens. During the research we are asking the participants to collect the ticks using a technique called flagging, and then to send the collected ticks to the researchers.

Ticks can be found everywhere, including our own garden. Although we generally associate humans with the cities, they also provide habitat for a wide range of animals. This is even more true to the urban greenspaces, like parks or gardens, where the plants give refuge to animals such as hedgehogs, rodents, birds or lizards. These animals are all hosts of different parasites, including ticks, so this way the ticks can get into the cities, and can be called relatively abundant in these places. With this research we are aiming to find out which tick species are present in the urban gardens, this way we can form a greater picture of the effects of urbanization on the spreading of ticks.

How can You participate in this research?

The first step is to fill in the google form containing the basic informations, this only takes a few minutes. Please, only fill in the questionnaire, if You really want to participate in the research.

After filling in the forms You will receive a package in the mail, containing the users manual and the cloth for the flag. At our website You can find a short video about the assembly of the flag, and how to use it. Please watch the video carefully for this information.

In nature the ticks wait at the shrub and grass layer to attach to animals passing by. During the flagging we drag the cloth on these plants, thus imitating a passing animal, so the tick grabs onto the flag. From there, we can easily remove the tick using a piece of tape. Please note, to only put the ticks collected from Your garden on the paper. The ticks from cats, dogs, or from You should be labeled clearly, that they are from a host, because they could have been collected outside of the garden for example at the forest. During the flagging You might get bit by a tick, for this we can’t be held accountable. In this case the most important thing is to remove the tick as soon as possible, for this, we recommend thoroughly checking Your body after every flagging, this way shortening the time of the tick bite.
After the flagging the ticks should be packaged and sent to the researchers. We will process your data, and send back to You, which tick species are present in Your garden.
