Key Points

Enhanced Surveillance for Chikungunya, Dengue, and Zika

• In mainland France, Aedes albopictus, known as the "tiger mosquito," is established in 33 departments. In 2017, Bas-Rhin and Haut-Rhin were classified as Level 1 departments under the plan to prevent the spread of chikungunya and dengue in mainland France, due to the mosquito vector’s long-term presence. These departments are part of the enhanced surveillance system for chikungunya, dengue, and Zika in mainland France, which is active from May 1 to November 30 each year.

• Between May 1 and June 23, 2017, one case of dengue and two cases of chikungunya were confirmed in the Grand-Est region.

Asthma Surveillance

• For the SOS Médecins associations in the region, asthma-related activity is also decreasing and is below the levels typically observed at this time of year.

Allergy Monitoring

• Activity related to allergies among SOS Médecins associations increased slightly in week 25 compared to the previous week.

• According to the pollen and allergy bulletin, the allergy risk is very high for grass pollen in the departments of Bas-Rhin, Haut-Rhin, and Vosges, and high in the seven other departments of the Grand Est region.
