Maringá, a city in Paraná, Brazil, is intensifying its fight against dengue fever with the implementation of innovative mosquito control techniques in high-traffic areas. The initiatives, launched as part of the “Páscoa Sem Dengue” (Easter Without Dengue) campaign, aim to curb the spread of the Aedes aegypti mosquito, which transmits dengue, Zika, and chikungunya viruses. This proactive approach comes as public health officials simultaneously bolster vaccination efforts against influenza, recognizing the importance of comprehensive preventative measures during the holiday season and beyond.
The city’s strategy centers around two key methods: Borrifação Residual Intradomiciliar (BRI Aedes), or intradomic residual spraying, and the installation of Estações Disseminadoras de Larvicida (EDLs), or larvalicide dissemination stations. These techniques, guided by the Brazilian National Dengue Control Program (PNCD), are being deployed in locations with significant pedestrian flow, including Praça da Catedral, the Terminal Urbano (Urban Terminal), the Rodoviária (Bus Terminal), and the Aeroporto de Maringá (Maringá Airport). Schools and municipal early childhood education centers have already received the EDLs earlier in the year, demonstrating a sustained commitment to preventative measures throughout 2026.
Innovative Techniques in Dengue Control
BRI Aedes involves the targeted spraying of insecticide inside homes and surrounding areas to kill adult mosquitoes. This method is particularly effective in reducing mosquito populations in areas where people congregate. The EDLs, are designed to release larvicide into water sources, preventing mosquito larvae from developing into adults. According to Antônio Carlos Nardi, Maringá’s Secretary of Health, “This work is important so that people who pass through these places feel safe. We need, every day, to combat Aedes and dengue, eliminating containers that collect stagnant water and breed the mosquito.”
The “Páscoa Sem Dengue” campaign is not an isolated event but rather a continuation of a series of public health initiatives launched earlier this year. Previous campaigns included “Réveillon sem Dengue” (Fresh Year Without Dengue), “Férias sem Dengue” (Vacation Without Dengue), “Volta às Aulas sem Dengue” (Back to School Without Dengue), and “Carnaval sem Dengue” (Carnival Without Dengue). This consistent, year-round approach underscores the city’s dedication to protecting its population from mosquito-borne diseases. The ongoing efforts highlight the complex challenge of controlling Aedes aegypti, a mosquito species known for its adaptability and ability to breed in various environments, even little containers of standing water.
Expanding Vaccination Access
Alongside the dengue prevention measures, Maringá is also expanding access to influenza vaccination. Two new groups are now eligible to receive the flu vaccine, demonstrating a broader public health strategy to protect residents during peak respiratory illness seasons. This initiative is particularly important as influenza and dengue can present similar initial symptoms, potentially overwhelming healthcare systems if both viruses circulate widely. The combined focus on dengue prevention and influenza vaccination reflects a proactive approach to safeguarding public health in Maringá.
The Secretary of Health emphasized the importance of prioritizing life during this period. “’Páscoa Sem Dengue’ reminds us to put life first. We must promote action for life: vaccinate our elderly, pregnant women, and children against the flu, and at the same time eliminate all containers that accumulate stagnant water. Dengue kills, and victory is ours only if we eliminate the mosquito from our environment,” Nardi stated. This message underscores the collective responsibility in preventing the spread of these diseases.
Community Involvement and Legislative Support
The success of these campaigns relies heavily on community participation and collaboration. Local authorities are actively engaging residents to eliminate breeding sites around their homes and businesses. This includes removing standing water from containers such as flower pots, tires, and gutters. The city is also benefiting from legislative support, with local councilors like Junior Bravin emphasizing the importance of monitoring public spending on vaccines and ensuring that campaigns reach those most in need. “The Municipality of Maringá is very concerned about this issue, which is fundamental for our city. In addition to monitoring public spending on vaccines, we demand the implementation of these campaigns to reach those who really need them,” Bravin noted.
The integrated approach of the Maringá health department, combining innovative mosquito control techniques with expanded vaccination programs and community engagement, offers a model for other cities facing similar public health challenges. The ongoing campaigns demonstrate a commitment to proactive prevention and a recognition of the interconnectedness of public health threats. The city’s dedication to eliminating breeding grounds, coupled with increased vaccination coverage, aims to create a safer and healthier environment for all residents.
Looking Ahead: Continued Vigilance
The “Páscoa Sem Dengue” campaign is scheduled to continue through the Easter holiday period, with ongoing monitoring and evaluation of its effectiveness. Health officials will continue to assess mosquito populations and dengue case numbers to adjust strategies as needed. The city is also preparing for the upcoming winter months, when influenza transmission typically increases, emphasizing the importance of continued vaccination efforts. The next official update on the campaign’s progress is expected in late April 2026, providing a comprehensive assessment of the initiatives’ impact.
The fight against dengue and influenza requires sustained vigilance and a collaborative effort from all stakeholders. By embracing innovative techniques, expanding vaccination access, and fostering community involvement, Maringá is demonstrating a proactive approach to protecting its population from these preventable diseases. The city’s commitment to public health serves as a valuable example for other communities seeking to address similar challenges.
