A93.2: Colorado tick fever

You have been infected by Colorado tick fever.

Colorado tick fever occurs in a mountainous region in the west of North America. It is caused by viruses. The viruses can be transmitted by a tick bite.

The illness can cause fever and headaches. The brain or the cerebral membranes may also be inflamed. On the outside of the brain and spinal cord there are three thin meninges (linings). A tough meninx, the dura mater, is on the outside. Below that are two soft meninges. If the cerebral membranes are inflamed, you may be sensitive to light and have a stiff neck. When the brain is inflamed you can lose consciousness or become confused. You can also suffer seizures. You may also no longer be able to move certain parts of your body properly. You may think and behave abnormally.
