Overview
Tick-borne encephalitis infections will often present themselves with biphasic clinical manifestations. Following an incubation period of 7 to 14 days, a patient will experience early onset, non-specific flu like symptoms. A patient will then experience a remission period of lessened symptoms or will appear to be completely asymptomatic. [1] A second phase will occur in which patients will experience an infection of the central nervous system resulting in a number of neurological, clinical manifestations.
History and Symptoms
- Symptoms associated with tick-borne encephalitis will appear after an average incubation period of 7 to 14 days.
- The infection usually occurs as a biphasic disease, with early onset symptoms, a period lessened symptoms or asymptomatic (remission), and finally a second phase within 20-30% of patients.[1]
Early Onset
- Fever
- Malaise
- Anorexia
- Muscle aches
- Headache
- Nausea
- Vomiting
Remission Period
- Lessened non-specific flu like symptoms
- Completely asymptomatic
Second Phase
- Infection of the central nervous system
- Symptoms associated with meningitis including: fever, headache, and a stiff neck.
- Encephalitis
- Drowsiness
- Confusion
- Sensory disturbances
- Motor abnormalities such as paralysis
- Meningoencephalitis.
- Although the above list relates to potential symptoms associated with a full course infection, many infected individuals will remain asymptomatic without any signs of symptoms.
- In addition to the the aforementioned list, symptoms may vary in severity, based on the subtype responsible for infection as well as mode of transmission.
