Which disease is transmitted by the bite of an infected tick, with symptoms occurring four to five days after being bitten?

The correct choice of Colorado tick fever is accurate as this disease specifically has a well-documented incubation period of four to five days following a tick bite. Colorado tick fever is caused by a virus transmitted through the bite of infected ticks, primarily the Rocky Mountain wood tick. After infection, symptoms such as fever, headache, and muscle aches typically manifest within this time frame, which aligns with the question's specification.

In contrast, tularemia can be transmitted by various routes, including insects, but the incubation period is usually shorter or can vary widely depending on the exposure route. Dengue fever is primarily transmitted by mosquitoes, not ticks, and typically has an incubation period of about 4 to 10 days after a mosquito bite. Psittacosis, caused by the bacterium Chlamydia psittaci, is associated with birds and does not involve tick transmission. Therefore, Colorado tick fever is the only option that matches the criteria of being transmitted by a tick with a defined symptom onset of four to five days post-bite.
