Chickenpox: Data
Using data from the Sentinelles network, among other sources, Santé publique France studies the epidemiological trends of chickenpox.
A childhood disease
2.2%
Complications in 2.2% of cases in 2017
The incidence of cases seen by general practitioners was estimated in 2017 at approximately 560,000 cases, representing an incidence rate of 854 cases per 10,000 inhabitants (95% CI: 814–894). In 2017, more than 94% of cases occurred in children aged 1 to 9 years. Complications were reported in 2.2% of cases, with 43% involving skin superinfections and 52% involving respiratory and ocular infections. Chickenpox in adults remains rare but can be very serious. The latest 2017 data from the Sentinelles network showed that 3.8% of cases occurred in individuals over 15 years of age.
A Spring Surge
Chickenpox is a “seasonal” disease for which a spring surge in the number of cases is observed every year (weeks 11 to 15); this is an expected increase in the disease. A second peak can also be observed in June/July (weeks 25 to 28).
