Thanks to citizen participation in the project, the arrival of the tiger mosquito to the Spanish Autonomous Communities of Andalucía and Aragon as well as a number of other cities and provinces was confirmed for the first time. Early detection of the urban Aedes is very important, particularly for planning and application of responses and different control measures.

Since 2014, citizen sightings of possible tiger mosquitos were made in more than 360 Spanish cities. This information helped confirm the extended presence of the tiger mosquito in coastal and southern cities of Catalonia, the Community of Valencia, the Region of Murcia, the Balearic Islands, and Andalucía. The sightings have also revealed that the mosquito is moving northeastward on the island of Majorca, and from the eastern and southern parts of Spain towards the interior. You can find more project information and results in the 2015 Annual Report.

Beginning in 2015, citizen sightings via Mosquito Alert have become an additional source of information used for control measures in different areas of Spain. In 2015, 20% of citizen sightings in Barcelona sent by Mosquito Alert were considered useful by the Barcelona Public Health Agency and integrated into its monitoring and control program. Also, in the city of Valencia 40% of new risk areas were detected thanks to citizen sightings sent with the Mosquito Alert app.
