Colorado tick fever is found in the Rocky Mountains of North America. It is also found in the western U.S and parts of Canada. The risk of getting the virus is highest for those who live in or travel to these regions, especially:
In mountain forest areas with heights of 4,000 to 10,000 feet
Between April and July
Symptoms usually appear 3 to 5 days after a tick bite. They may last for 3 weeks.
Symptoms of Colorado tick fever may be:
High fever and chills
Eye redness, sensitivity to light, or pain behind the eyes
Feeling tired or weak
Nausea, vomiting, or diarrhea
The doctor will ask about your symptoms and health history. A physical exam will be done. Blood tests may be done to detect the virus and look for other problems.
There is no specific treatment for Colorado tick fever. Most people recover in 1 week. The goal is to ease symptoms. Options are:
Pain medicines, such as acetaminophen—to ease pain and fever
Fluids—to stay hydrated
Serious problems are very rare. They may include aseptic meningitis, encephalitis, and hemorrhagic fever. Severe symptoms or problems need hospital care.
To reduce the risk of Colorado tick fever:
Avoid tick-infested areas.
Wear light-colored clothing, and pants tucked into socks.
