According to the *Annals of Agricultural and Environmental Medicine*, the researchers at the university conducted a study to identify the chemical and biological factors that explain why ticks are attracted to some people more than others. Among the factors studied was the impact of human blood type.
In the study, scientists isolated a group of *Ixodes ricinus* ticks in a laboratory environment and allowed them access to blood samples from various blood types. The results showed that the ticks were consistently attracted to blood type A (II). After repeating the experiment more than 100 times, the ticks showed a similar response.
The researchers pointed out that ticks are small insects that people may encounter while outdoors or in areas with high humidity. These insects can transmit dangerous parasites to humans, such as the tick-borne encephalitis virus, which can affect the central nervous system and potentially cause disability or death in some cases.
Symptoms of tick-borne encephalitis include fever, nausea, headache, light sensitivity, and severe drowsiness. It may sometimes present as seizures or loss of consciousness.
Tick bites can also lead to "Lyme disease," a bacterial infection identifiable by the appearance of red spots on the skin that expand and itch. After a few days, symptoms of Lyme disease appear, such as fever, headaches, limb pain, muscle cramps, and difficulty speaking.
