Care to be adopted
– Elimination of standing water outbreaks: emptying, cleaning and keeping covered containers that can accumulate water, such as tires, plant pots, water boxes, bottles and gutters;
– Keep tightly closed water tanks and reservoirs: This prevents the Aedes aegypti mosquito from having access to clean water to lay its eggs;
-Discard the trash correctly: pack the garbage well and keep it in a closed place until collection. Avoid the accumulation of outdoor recyclable materials;
– Use protective screens and repellents: Install screens on doors and windows and use repellent in exposed areas of the body, especially during the day, when the mosquito is more active;
– Participate in community prevention actions;
-Involve in local campaigns, encourage neighbors and family members to keep their backyards clean and share information on dengue prevention.
