RMSF is a potentially fatal but curable tick-borne disease. Symptoms typically appear within 2-14 days after a tick bite and may include:
- Fever
- Headache
- Nausea with or without vomiting
- Rash (90% of cases have a rash)
- Muscle and joint pain
- Fatigue
Although less common, illness can progress and cause:
- Breathing problems caused by fluid in/around the lungs
- Irregular rhythm of the heart
- Enlargement of the liver and spleen
- Bleeding abnormalities
- Skin inflammation and damage
- Neurological problems such as inflammation of the brain
Overall, the fatality rate varies and is generally low, especially with treatment. It increases with age and can be much higher if left untreated.
If you suspect you have been exposed to ticks and are experiencing symptoms consistent with RMSF, it is important to seek medical attention promptly.
