Symptoms & diagnosis
Most sources describe an incubation period of 4–14 days, with longer periods reported rarely. During travel-related monitoring, authorities may use conservative windows when advising self-observation.
Common symptom pattern
Early illness can resemble many viral infections (fever, headache, myalgia). Severe disease may involve encephalitis and/or respiratory complications.
Testing
- RT‑PCR during acute illness from appropriate specimens
- Serology (e.g., ELISA) for antibody detection
- Testing is typically coordinated through public health authorities and specialized laboratories
