- Preparing For Your Appointment
Rocky Mountain spotted fever can be difficult to diagnose because the early signs and symptoms are similar to those caused by many other diseases.Laboratory tests can check a blood sample, rash specimen or the tick itself for evidence of the organism that causes the infection. Because early treatment with antibiotics is so important, doctors don't wait for these test results before starting treatment if Rocky Mountain fever is strongly suspected.
People who develop Rocky Mountain spotted fever are much more likely to avoid complications if treated within five days of developing symptoms. That's why your doctor will probably have you begin antibiotic therapy before receiving conclusive test results.Doxycycline (Monodox, Vibramycin, others) is the most effective treatment for Rocky Mountain spotted fever, but it's not a good choice if you're pregnant. In that case, your doctor may prescribe chloramphenicol as an alternative.
You'll likely start by seeing your family doctor. In some cases, you might be referred to a doctor who specializes in infectious diseases.

Ehrlichiosis is caused by ehrlichia bacteria and is transmitted primarily by the Lone Star tick.Ticks feed on blood, latching onto a host and feeding until they're swollen to many times their normal size. During feeding, ticks that carry disease-producing bacteria can transmit the bacteria to a healthy host. Or they may pick up bacteria themselves if the host, such as a white-tailed deer or a coyote, is infected.Usually, to get ehrlichiosis, you must be bitten by an infected tick. The bacteri...
