Situation and vulnerability
The site of exposure is important, especially after activities in the US regions where the virus is circulating. A statistical rarity does not make it possible to rule out a table of concern.
Signs and limits of their interpretation
Fever, headache, vomiting or diarrhoea may be accompanied by neurological disorders. Seizure is possible after a serious form.
Diagnosis and monitoring
Report the stay and exposure to mosquitoes. Encephalitis examinations must distinguish several causes; the title of the disease is not sufficient for diagnosis.
Check these markers in the CDC reference →
Prevention and care
Reduce the bites and follow local alerts. Unusual somnolence, convulsions or behavioural change requires urgent care.
Practical issues
Does the term "equine" reserve the disease to horses?
No: This sheet concerns human infection. The CDC describes a transmission to humans by mosquitoes, without a preventive vaccine available to people.
Preparing for an exchange with a professional
- Travel and outside activities
- Fever dates and behavioural disorders
- Local exhibitions and bulletins
Bring the full minutes and dates. This information facilitates evaluation; its collection must not delay an urgent appeal.
