Ticks, small arachnids known for their ability to transmit a wide range of infectious diseases, have become a major public health problem worldwide. The prevalence and geographic distribution of tick-borne diseases have steadily increased with global climate change and the increasing encroachment of human activities on the natural environment.

These diseases are caused by a variety of bacteria, viruses and parasites and can have serious and even life-threatening consequences if not diagnosed and treated appropriately. Well-documented examples include Lyme disease, Rocky Mountain spotted fever, anaplasmosis, babesiosis, Powassan virus infection and Crimean-Congo hemorrhagic fever. Lyme disease, caused by Borrelia burgdorferi, is one of the most common tick-borne diseases, and symptoms include a characteristic bull's-eye rash, neurological complications and joint inflammation.

Symptoms vary widely and usually include fever, chills, headache, fatigue and a characteristic rash, but if the initial infection is not treated promptly, it also leads to long-term complications such as arthritis, neurological disorders and heart disease.

Preventing the spread of tick-borne diseases and reducing their public health burden requires a multifaceted approach. This includes raising awareness among health-care providers and the public, implementing effective tick control strategies, and supporting ongoing research to improve diagnostic tools and treatment options. Early detection is critical, as timely medical care can greatly improve patient outcomes.

Moreover, the rising incidence of these infectious diseases highlights the need for global cooperation to address the complex interplay between environmental change, human activities and the emergence of zoonotic diseases. Policymakers, public health authorities and the scientific community must work together to develop comprehensive strategies to protect communities and safeguard global public health.

As the threat posed by tick-borne diseases continues to escalate, a coordinated, evidence-based approach is essential to effectively control this growing public health challenge. Through sustained advocacy, proactive prevention and ongoing research, the medical and scientific communities can work to mitigate the impact of these infectious diseases and promote the well-being of people around the world.
