Early Treatment

Why Early Treatment Matters

Tick-borne and zoonotic infections can mimic other illnesses, making them difficult to identify. Without proper care, these infections may lead to:

  • Chronic fatigue, pain, or neurological issues
  • Persistent joint inflammation or arthritis
  • Organ complications (heart, liver, kidneys, or nervous system)
  • Life-threatening illness if untreated


A board-certified Colorado Infectious Disease specialist ensures timely diagnosis, accurate testing, and treatment that prevents long-term complications.

FAQs

Frequently Asked Questions

Do all tick bites cause Lyme disease?

No. Only certain species of ticks transmit Lyme, and not every bite leads to infection. Dr. Coulter evaluates risk based on the type of tick, duration of attachment, geographic location,  and your symptoms.

If you develop fever, rash, or flu-like symptoms within days or weeks of a tick bite, it’s important to see a doctor right away.

Yes. Infections like Bartonella (“cat scratch disease”) or even fungal infections can spread from animals to humans. Dr. Coulter provides guidance for safe prevention and treatment.
