Who could benefit from this research
✓Could help
Ideal participants are residents of participating neighborhoods in Iquitos or Lima who are willing to use mobile messaging and take part in community mosquito-control activities.
✕Less likely to help
People who live outside the targeted neighborhoods, cannot access or use the phone messaging tool, or need immediate hospital care for severe dengue are unlikely to benefit directly from joining.
What this research studies
You and your neighbors would be invited to learn and carry out practical mosquito-control actions in and around your homes, supported by a phone messaging platform called DengueChat. Local health teams and researchers will set up better surveillance of mosquitoes and fevers, improve how suspected dengue cases are triaged, and launch focused responses when transmission rises. The program emphasizes two-way information sharing between residents, health workers, and authorities so communities can report risks and get timely help. The team uses proven implementation frameworks and lessons from past outbreaks to tailor the program to neighborhoods in Iquitos and Lima.
Why it matters
Potential benefit: If successful, the program could reduce local mosquito breeding, lower dengue cases, and speed up care and response during outbreaks.
How similar studies have gone: A similar DengueChat approach showed promise mobilizing communities in Nicaragua and Paraguay, but this integrated, locally adapted program is a newer, broader effort.
