Situation and vulnerability
Unvaccinated persons exposed in the transmission zone are affected. A special assessment precedes vaccination in case of pregnancy, immunodepression or after 60 years.
Signs and limits of their interpretation
Fever, curvature, nausea and weakness may precede improvement. Some forms evolve into jaundice, bleeding and organ failure.
Diagnosis and monitoring
Confirmation is based on detection of the virus in the blood at the beginning and then antibody tests. Symptoms may resemble malaria or other hepatitis.

Prevention and care
Prepare the trip with a professional: destination, contraindications and vaccination certificate. Wear covering clothing and use a suitable repellent. Jaundice or bleeding requires urgent management.
Practical issues
Is a mosquito net enough at night?
No: Responsible mosquitoes sting day by day. Protection during daytime activities is still necessary, even with equipped accommodation.
Preparing for an exchange with a professional
- Itinerary and dates of stay
- immunisation certificate and booklet
- History relevant to the vaccination evaluation
Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.
