Key Points

Enhanced Surveillance of 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 July 21, 2017, three cases of dengue and two cases of chikungunya were confirmed in the Grand Est region.

Asthma Surveillance

• Emergency department activity related to asthma decreased during week 29 (July 17–23). It fell within the range observed during this period in 2015 and was below the 2016 levels.

• For the SOS Médecins associations in the region, asthma-related activity was stable in week 29. It was lower than the figures observed last year during the same period and higher than those observed in 2015.

Allergy Monitoring

• Activity related to allergies among SOS Médecins associations has been fluctuating for several weeks and is comparable to what was observed during the same period in the previous two years.

• According to the pollen and allergy bulletin, the allergy risk from grass pollen is very low in the Ardennes and Moselle departments, and low in the other departments.

Mortality Monitoring

• As of July 25, the number of deaths observed over the past few weeks falls within the usual range of fluctuations.
