Colorado Tick Fever

Colorado Tick Fever is an illness caused by a virus carried by small mammals, such as ground squirrels, porcupines, chipmunks, and ticks. The virus can be transmitted to humans by the bite of an infected Rocky Mountain wood tick. Colorado Tick Fever is the most common tick-borne disease in Colorado, it is believed , however, that most cases go unrecognized.

  • Fever
  • Headache
  • Body aches
  • Nausea and abdominal pain
  • Lethargy

Symptoms usually last 4-5 days, followed by an apparent recovery, then a relapse with symptoms for 2-3 more days. Complete recovery can take 2 or 3 weeks.

The disease is not life threatening and infection results in life-long immunity.

    1. Hi HVAC Schools in CO. I am not sure this message was meant for our blog. We do not provide medical advice on this blog, we offer preventive advice only. If you have a friend that is concerned about symptoms they are experiencing have her call her health care provider since there are a number of illnesses that they could be attributed to. Or, consider calling 911 or going to the emergency room. Thanks for reading.
