Situation and vulnerability
Infants and elderly or chronically ill people are more exposed to severe forms.
Signs and limits of their interpretation
Fever, joint pain, fatigue and rash may occur. Joint pain may persist after the acute episode.
Diagnosis and monitoring
The search for the virus or antibodies depends on the delay from the symptoms. Dengue and Zika can travel in the same areas and look alike.

Prevention and care
Protect yourself from injections, including during the first week of illness. A professional evaluates analgesics; avoid aspirin and anti-inflammatory drugs as long as a dengue is not ruled out.
Practical issues
Do persistent pains prove that the virus is still circulating in the blood?
No. They can prolong the disease without translating the same phase of infection. Monitoring is useful if it limits activities.

- Fever onset and joint pain
- Medicinal products taken and chronic diseases
Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.
