Situation and vulnerability
Pregnancy, immunosuppression, adult and very young age change the risk. A contact is soon to be notified if the person is vulnerable and not immune.
Signs and limits of their interpretation
Injuries that demangent often appear in several bursts, with fever and fatigue. Forms after vaccination may be less typical.
Diagnosis and monitoring
The professional examines the eruption and the context; a sampling may be necessary. An image does not always distinguish varicella and other eruptions.

Prevention and care
Immunization depends on national recommendations. Notify before consulting to limit contact with fragile people.
Practical issues
Can we pass on the chickenpox before the eruption?
Yes, infectiousness may precede eruption. Waiting to see all the lesions is not enough to appreciate an exposure.
Preparing for an exchange with a professional
- Date of contact and onset of eruption
- Pregnancy, immunosuppression and vaccination
- Fragile people encountered
