An acute febrile illness and leukopenia after tick bite.

Leukopenia with a relative lymphocytosis and atypical lymphocytes with thrombocytopenia.
Serology or PCR to diagnose.
Bit by a wood tick in the western United States and Canada. Dermacentor andersoni is the vector and found at 4000 to 10,000-foot elevations; it is my understanding that Colorado is particularly high, but in a different way than, say, Eugene, Oregon. Lets just say the sweetish haze in the air at U of O was not the burning of grass of a lawn kind.(Geographic Distribution Map)
Due to the Coltiviruses.
The tick should be present.
