Eliminate the water, and you stop the cycle before it starts
En la región de Tacna, Perú, el sistema de salud EsSalud ha emprendido una estrategia metódica contra el dengue: en lugar de esperar que la enfermedad se propague, forma a sus propios trabajadores para que reconozcan y eliminen los criaderos del mosquito Aedes aegypti antes de que el ciclo de reproducción pueda completarse. Es una apuesta por convertir la vigilancia en un acto cotidiano y colectivo, reconociendo que la prevención más eficaz no reside solo en los especialistas, sino en quienes habitan los espacios donde la amenaza puede surgir.
- El dengue sigue circulando en el Perú y Tacna no es inmune: la urgencia de actuar antes de que los brotes escalen impulsa toda la estrategia.
- Los propios establecimientos de salud pueden convertirse en criaderos si no se mantienen con rigor, lo que añade una paradoja incómoda al problema.
- EsSalud Tacna organizó una capacitación técnica especializada dirigida al personal institucional, con foco en identificar sitios de reproducción y cortar el ciclo del mosquito desde la fase de huevo.
- El biólogo Javier Villanueva guió a los participantes a pasar de la conciencia pasiva a la acción directa: detectar, eliminar y reportar sin esperar instrucciones superiores.
- La red de salud se ha comprometido a sostener estas capacitaciones en todas sus instalaciones, combinándolas con monitoreo periódico y reuniones de coordinación para que la vigilancia no decaiga.
En Tacna, Perú, EsSalud ha decidido enfrentar el dengue desde adentro: capacitando a los trabajadores de hospitales y clínicas para que sean ellos quienes identifiquen y eliminen los criaderos del Aedes aegypti, el mosquito transmisor de la enfermedad. La lógica es simple pero poderosa: si se destruyen los sitios donde el mosquito deposita sus huevos antes de que eclosionen, se interrumpe el ciclo antes de que exista un adulto capaz de transmitir el virus.
La red asistencial organizó una sesión técnica liderada por Javier Villanueva, biólogo de la oficina de epidemiología de la Dirección Regional de Salud. Aunque el grupo inicial fue el personal de SILSA, empresa que opera dentro del sistema, la iniciativa forma parte de un plan más amplio —el Plan de Prevención, Manejo y Control del Dengue 2026— que busca capacitar a todos los trabajadores de cada establecimiento de la región. Villanueva guió a los participantes a través del ciclo biológico del mosquito, los principales sitios de cría y las intervenciones que realmente funcionan para detenerlo.
Lo que distingue este enfoque es su carácter transversal: la responsabilidad del control vectorial no recae solo en epidemiólogos, sino en cualquier persona que trabaje en esos espacios a diario. Los participantes practicaron la identificación de criaderos potenciales y aprendieron a actuar sin necesidad de esperar una orden desde arriba.
EsSalud Tacna ha asumido el compromiso de mantener estas capacitaciones de forma continua en todas sus instalaciones, acompañadas de charlas educativas, reuniones de coordinación y supervisión periódica. El mensaje es claro: interrumpir la reproducción del mosquito exige vigilancia constante y una fuerza laboral que sepa exactamente qué buscar y por qué importa hacerlo.
In the Tacna region of Peru, health officials are taking a methodical approach to dengue prevention: they're training the people who work in hospitals and clinics to recognize and eliminate the mosquito that spreads the disease. The effort centers on the Aedes aegypti, a mosquito that has become a persistent public health concern, and the strategy is straightforward—teach workers to spot where these insects breed, understand how they develop, and remove breeding grounds before the mosquitoes can multiply.
EsSalud's Tacna network, the regional health care system, organized a specialized training session led by Javier Villanueva, a biologist with the Regional Health Directorate's epidemiology office. The session targeted staff from SILSA, a company that works within the health system, but it was part of a broader effort to train all personnel across every health facility in the region. The training was designed around the 2026 Dengue Prevention, Management, and Control Plan—a coordinated response that recognizes dengue as an ongoing threat requiring sustained attention.
Villanueva walked participants through the fundamentals: how to identify the main breeding sites where Aedes aegypti lay eggs, what the mosquito's life cycle looks like, and which interventions actually work to stop that cycle. The emphasis was on early action. If you eliminate standing water and other breeding grounds before eggs hatch, you prevent the mosquitoes from ever becoming adults capable of transmitting the virus. The training stressed that this work happens in health facilities themselves—clinics and hospitals can be breeding grounds if they're not carefully maintained—and in the workplaces where health workers spend their time.
What makes this approach notable is that it treats dengue prevention as a shared responsibility across the entire health system. It's not just epidemiologists or disease specialists who need to understand vector control; it's the people who work in those facilities every day. During the session, participants practiced identifying potential breeding sites, discussed how to eliminate them, and learned what ongoing surveillance looks like. The goal was to move from passive awareness to active participation—workers who can spot a problem and address it without waiting for instructions from above.
EsSalud Tacna has committed to making this training continuous. The health network is conducting these sessions across all its facilities, pairing them with educational talks, coordination meetings, regular monitoring, and periodic supervision. The message is consistent: dengue transmission is preventable if you interrupt the mosquito's reproduction cycle, and that requires constant vigilance and knowledge among the people who work in health settings and other institutions. The network frames this as a commitment to protecting both the people enrolled in the EsSalud system and the broader population of Tacna. As dengue continues to circulate in Peru, the ability to respond quickly—to spot breeding sites, eliminate them, and track where the mosquito is active—depends on having a workforce that understands what they're looking for and why it matters.

Why focus training on the people who work in hospitals rather than, say, the general public?
Because health facilities themselves can become breeding grounds if they're not managed carefully. A water container in a clinic, a flower vase, a clogged drain—these are perfect for Aedes aegypti. If the staff doesn't know what to look for, the mosquito can breed right there in the place meant to treat dengue patients.
So this is about preventing dengue from spreading within the health system itself?
Partly that, yes. But it's also about creating a trained workforce that can recognize the problem everywhere—in their workplaces, in the facilities they manage. If health workers understand the mosquito's life cycle, they become part of the surveillance network.
The training mentions interrupting reproduction from the egg phase. Why is that specific stage important?
Because it's the easiest point to intervene. Eggs need water to hatch. Remove the water, and you've stopped the cycle before it starts. You don't need pesticides or complicated interventions—just elimination of breeding sites.
Is this a new problem in Tacna, or has dengue been circulating there for a while?
The fact that they have a formal 2026 prevention plan suggests it's an ongoing concern. This isn't a response to an emergency; it's a sustained effort to keep the mosquito population low enough that transmission doesn't accelerate.
What happens if the training doesn't stick? If workers forget or don't apply what they learned?
That's why they're doing this continuously—regular training, supervision, monitoring. It's not a one-time event. The idea is to build a culture where vector control is part of how the health system operates, not an occasional campaign.
