Humans contract tick fever following a bite from an infected Rocky Mountain wood tick, states the Centers for Disease Control and Prevention. The ticks usually get the virus after feeding on the blood of an animal that has the virus, such as mice, chipmunks and squirrels. The virus cannot transmit from one person to another, but it can occur by blood transfusion, which is rare.
Commonly known as Colorado tick fever, this disease tends to occur between March and September, and it is common in Colorado, says MedlinePlus. The symptoms are likely to occur three to six days after the tick bite. The condition is characterized by a fever that comes and goes. Other symptoms include muscle aches, nausea, vomiting, skin pain and light sensitivity. In most cases, the symptoms clear up without treatment within 10 days, says Healthline.
As of 2015, there is no particular treatment for Colorado tick fever, notes MedlinePlus. Doctors ensure a complete removal of the tick from the skin. Some patients may use pain relievers if there is a need. Children with tick fever must not use aspirin as it increases the risk of Reye's syndrome. Possible complications linked to tick fever include encephalitis, hemorrhagic fever and aseptic meningitis.
