Pathogenesis of tick-borne pathogens

Tick-borne pathogens, such as bacteria, viruses, or parasites, are transmitted through tick bites. When a tick feeds on an infected animal or person, these organisms enter the tick’s digestive system. If the tick later bites a human, the pathogens are introduced into the skin and bloodstream. They then travel to various tissues, infecting cells and evading the immune system. This process can cause symptoms like fever, fatigue, and other illness. The specific way they cause disease depends on the pathogen, but generally, they disrupt normal bodily functions by damaging cells or provoking inflammation.
