Stagnant water remains the biggest ally of the dengue mosquito in Madeira

Eliminating locations with accumulated water is the most effective way to prevent diseases transmitted by the Aedes aegypti mosquito.

Stagnant water remains the biggest ally of the dengue mosquito in Madeira

A photograph sent by a reader shows an uncovered well in Santa Luzia with accumulated water and aquatic vegetation. While the image does not confirm the presence of the Aedes aegypti mosquito, it serves as a reminder of the need to eliminate breeding sites.

The mosquito, first detected in Madeira in 2005, can transmit diseases such as dengue, zika, and chikungunya. Health authorities emphasize the importance of surveillance and control, noting that the mosquito breeds in small containers with stagnant water, like tanks, pots, tires, and clogged gutters.

The mosquito's life cycle is rapid in favorable conditions, completing in about a week. Technical identification of Aedes aegypti is crucial and cannot be determined solely from photos of water reservoirs. Prevention relies on the constant elimination of potential breeding grounds.
