Situation and vulnerability
Pregnancy and immunodepression require special attention. Some domestic rodents may be infected after contact with contaminated colonies or animals.
Signs and limits of their interpretation
A febrile phase may be followed, after improvement, by headache, stiffness of the neck or confusion. Neurological signs require rapid assessment.
Diagnosis and monitoring
The virus or its antibodies can be searched in blood or cerebrospinal fluid. Mention rodent contacts and chronology in two phases.
Check these markers in the CDC reference →
Prevention and care
Avoid contact with wild mice and apply rodent handling precautions. In case of exposed pregnancy, ask for appropriate medical advice.
Practical issues
Are domestic rodents always safe?
No: Domestic mice or hamsters may be infected. Their origin and contact with wild rodents should be considered, without assigning any disease to the animal.
Preparing for an exchange with a professional
- Domestic rodents or infestation
- Pregnancy or immunosuppression
- Chronology of fever and neurological signs
