As described by the portal narodowekleszczobranie.pl, Hyalomma ticks, also known as "Monster ticks" due to their large size and fast movement, pose a threat to both humans and animals. Commonly found in Africa, Southeast Asia, and Southern Europe, these arachnids carry dangerous pathogens that can cause serious diseases.
African Hyalomma Ticks in Poland: They Are Quite Distinctive
"Monster ticks" are characterized by their long, striped legs, and their bodies are reddish-brown or almost black. Importantly, adult Hyalomma ticks can be up to four times larger than the common ticks found in Poland—reaching up to 5 mm in length and 3 mm in width. When engorged with blood, they can grow to over 1 cm in length.
The range of the African ticks continues to expand as their larvae migrate with birds. These arachnids prefer warm and dry places, making the spring and summer weather in Northern Europe suitable for their survival. Adult specimens have recently been observed in several countries, including Germany and Sweden. According to the Polish Press Agency (PAP), the first three specimens have also been spotted in Poland—in the areas near Poznań, Częstochowa, and Barankowo.
"Monster Ticks" Pose a Deadly Threat
Narodowekleszczobranie.pl reminded that Hyalomma ticks carry both bacteria and viruses, including frequent vectors of the Crimean-Congo hemorrhagic fever virus (CCHFV). This virus is associated with a mortality rate ranging from 10% to 60%, and there is currently no cure or vaccine available.
In addition to hemorrhagic fever, some species of Hyalomma also carry the West Nile virus, Venezuelan equine encephalitis virus, African horse sickness virus, and rickettsia, bacteria that cause inflammation of blood vessels—mainly small arteries and capillaries.
