Mosquitoes, which carry dangerous diseases, are causing concern in Lisbon. Find out what precautions you should take

The mosquito species Aedes albopictus, a carrier of the chikungunya, dengue and zika viruses, was first identified in Lisbon, in the parish of Benfica. The Directorate General of Health (DGS) has already strengthened surveillance and is taking measures to combat mosquitoes.

Health experts warn about the need for prevention. Mosquito larvae are commonly found in standing water, trash cans, or gutters. Prevention measures include washing and cleaning drinking fountains and pet bowls once a week, and keeping gutters, downspouts, and gutters clear. It is also recommended to remove containers containing potted plants or turn them upside down to avoid water accumulation. Wells, tanks and other water reservoirs should be covered to prevent mosquitoes from entering. The SRS also states that “swimming pools must be treated and cleaned, covered or emptied.”

The mosquito has already been detected in the north in 2017, in the Algarve in 2018 and in the Alentejo in 2022. It spread throughout southern Europe. The aedes albopictus mosquito originates from the tropical forests of Southeast Asia. Over the past 50 years it has spread to several countries in Central and Southern Europe.
