Once a person is infected, flea-borne typhus normally has an incubation period of 6-14 days before symptoms appear. Typical symptoms consist of:

• Severe headache
• Sustained high fever (104° F) for many days
• Body aches
• Weakness
• Confusion
• Sensitivity to light
• A rash on the chest, back, arms and/or legs appears in approximately 50% of patients

See a doctor immediately if you have any of these symptoms.
