WhatsApp Made the Tank Visit Stick
Community visits plus messaging improved household prevention practices and reduced mosquito-vector measures more than visits alone.
Summary
Community visits plus messaging improved household prevention practices and reduced mosquito-vector measures more than visits alone.
A three-group implementation study in two Colombian municipalities compared usual control, community visits, and visits plus WhatsApp support. Among 874 households, the combined group improved management of small breeding sites by 15.9 percentage points and showed broader gains in preventive practice and entomological indices than visits alone; participants also rated the messaging acceptable. The quasi-experimental design supports WhatsApp as a practical engagement layer in this setting, but it does not establish universal effectiveness and the trial was registered retrospectively.
