More than 3 decades ago, when Mercedes Peratta Ruiz started out as community health volunteer in her village in northern Honduras, she would typically see about 150 cases of malaria every year. “Many people died”, she said, “mostly children.” But in recent years the number of cases started to decline, and today almost no patients come and visit her anymore. Although diagnostics and treatment have improved a lot, Mercedes believes that “the biggest change is that today, everybody realizes the importance of treatment. There is more education today”. And less malaria.
