ECDC rapid risk assessment: autochthonous cases of dengue in Spain and France

The European Centre for Disease Prevention and Control (ECDC) has published a rapid risk assessment concerning autochthonous cases of dengue in Spain and France.

On 16 September 2019, the Catalonian Public Health Agency confirmed an autochthonous case of dengue in a resident of Barcelonès County in Catalonia, Spain. The case had onset of symptoms on 6 September 2019, with no recent travel history outside of Spain. Epidemiological investigations in Catalonia are ongoing, and further cases may be detected.

On 20 September 2019, the regional public health agency of Provence-Alpes-Côte d’Azur region reported a locally acquired confirmed case of dengue. Four additional cases in the direct vicinity have since been identified. In addition, the regional public health agency of Auvergne-Rhône-Alpes reported a locally acquired probable dengue case in a resident of a suburban area of the city of Lyon.

To date, these three events should be considered as independent because epidemiological investigations have not identified any epidemiological links between them. The probability of further local sustained transmission remains very low in Spain and France, and environmental conditions will become progressively less suitable for transmission over the autumn season. 

Based on ECDC’s epidemiological assessment, the risk that visitors to the affected area will become infected and subsequently introduce the virus and thus initiate further local transmission in their country of residence cannot be excluded, but remains very low.

Further information for travellers can be found on the TRAVAX (for health professionals) and fitfortravel (for the general public) websites.
