Specific evidence-based interventions that may lower disease prevalence include:

  • The SAFE (surgery, antibiotics, facial cleanliness, environmental sanitation) strategy to address trachoma, primarily the facial cleanliness and the environmental sanitation components[6]
  • Hand-washing with soap at critical times and nail clipping to decrease reinfection rates, although further research is needed to develop and implement similar interventions at scale[citation needed]
  • Programs combining anthelmintic drug administration with interventions to increase environmental sanitation (such as decreasing fecal contamination)[7]
