On 9 October 2018, French authorities reported that a case of locally-acquired dengue was identified in a patient living in St Laurent-du-Var, immediately to the west of Nice. The patient became unwell on 21 September and had not travelled outside the Provence-Alpes-Côte d’Azur in the previous 15 days.
Additionally, according to media quoting public health authorities, two residents of Alhama de Murcia in Spain have been diagnosed with locally acquired dengue. The two people became unwell in late August, having travelled within Murcia, as well as to Madrid and Cadiz. They had not travelled to any other country, leading public health authorities to conclude that the infection was acquired in Spain.
Aedes albopictus, the Asian tiger mosquito that transmits dengue virus, is common in both these European areas.
