The most effective measure to prevent and break the transmission cycle of dengue and other diseases transmitted by the Aedes aegypti mosquito is the elimination or neutralization of breeding sites, that is, of all containers or objects that can accumulate water.
Importance of Continuous Measures
Since the mosquito eggs can withstand low temperatures and drought conditions, it is crucial that prevention and control measures are carried out continuously throughout the year. Only then can an effective reduction in the spread of these diseases be ensured.
Recommendations to prevent dengue
- Remove all unused containers that can accumulate water (cans, bottles, tires, etc.) inside and outside the home and/or workplace.
- Puncture unusable containers before discarding them. If not possible, break or compact them. Place them in closed bags for safe removal by waste collectors.
- Turn over, cover, or protect useful objects found outside that can collect rain or irrigation water (buckets, basins, drums, toys, etc.).
- Brush, clean, and change the water in animal drinking troughs, air conditioning or rain drainage collectors. Brushing or scrubbing the internal walls of the container is essential to dislodge mosquito eggs attached there.
- Avoid having plants in water. Replace the water in pots or plant containers with sand, soil, or other suitable substrate. Otherwise, change the water frequently (approximately every 2/3 days, checking for larvae in the roots) and scrub the internal walls of the vases.
- Fill plant pot saucers with sand to absorb excess water when watering.
- Keep yards and gardens free of weeds.
- Unclog gutters and rain drains.
- Pour boiling water on the internal walls of grates and place mosquito nets on them.
- Keep tanks and large containers (cisterns, tanks, etc.) used to collect and store water covered.
- Keep swimming pools clean and chlorinated. Cover them when not in use.
