What will happen if a tick is not removed from the skin? - briefly
A feeding tick that stays attached for several days raises the likelihood of transmitting pathogens such as Borrelia burgdorferi, the cause of Lyme disease. Prolonged attachment can also produce local skin irritation, inflammation, or secondary infection.
What will happen if a tick is not removed from the skin? - in detail
Leaving a tick attached to the skin creates a pathway for pathogens and toxins to enter the host. Within the first 24 hours, the tick’s mouthparts embed deeply, causing a localized inflammatory response that may appear as a red papule or a small, painless bump. If the attachment persists beyond 48 hours, the probability of transmitting infectious agents rises sharply.

Bacterial infections
– Borrelia burgdorferi, the agent of Lyme disease, can be transferred after roughly 36 hours of feeding. Early signs include erythema migrans, fever, fatigue, and joint pain.
– Rickettsia species, responsible for Rocky Mountain spotted fever and other spotted fevers, may be transmitted within 12–24 hours, leading to high fever, rash, and vascular injury. -
Viral and protozoan diseases
– Powassan virus, though rare, can be transmitted in a matter of hours, producing encephalitis and meningitis.
– Babesia microti, a protozoan parasite, may enter the bloodstream after several days, causing hemolytic anemia and flu‑like symptoms. -
Tick‑borne toxins
– Salivary proteins can induce allergic reactions, ranging from mild pruritus to severe anaphylaxis.
– In certain species, neurotoxic secretions cause tick paralysis; symptoms progress from weakness to respiratory failure if the tick remains attached for several days. -
Secondary complications
– Prolonged skin irritation may lead to secondary bacterial infection, presenting as pus‑filled lesions or cellulitis.
– Persistent local inflammation can result in scar formation or permanent pigment changes.
Risk assessment correlates directly with attachment duration, tick species, and geographic prevalence of pathogens. Prompt removal—grasping the tick as close to the skin as possible with fine‑pointed tweezers and applying steady upward traction—reduces the likelihood of pathogen transmission and minimizes tissue damage. After extraction, cleaning the bite site with antiseptic and monitoring for fever, rash, or neurological signs for at least four weeks is advisable. Early medical evaluation and appropriate antimicrobial therapy improve outcomes for most tick‑borne illnesses.
