Study suggests ticks may avoid blood type B, but experts urge caution

As warmer weather arrives, the risk of encountering ticks in forests, parks, and grassy areas increases. These arachnids are known carriers of serious infections, including Lyme disease and tick-borne encephalitis, posing a significant health concern.

Intriguingly, a small experimental study conducted by Czech scientists observed the reactions of 100 tick nymphs to different ABO blood groups. The findings indicated that ticks showed a preference for blood type A (II), while appearing least attracted to blood type B (III). The difference between these groups was statistically significant in the experiment.

However, researchers caution against relying solely on blood type for protection. The study was limited in scope and conducted under laboratory conditions. Therefore, the observed influence of blood type on tick preference is considered only a possibility. The scientists stressed that people with blood type B (III) are not immune to tick bites.

Regardless of blood type, experts universally recommend robust preventive measures. When venturing outdoors, it is advisable to wear closed-toe clothing and long trousers, avoid tall grass and dense bushes, and use registered tick repellents. Upon returning home, a thorough body check for ticks is essential for oneself, children, and pets. Prompt removal of any attached tick is also recommended. It's important to note that while vaccines exist for tick-borne encephalitis, they do not protect against Lyme disease or other tick-borne illnesses.
