Risk factors
By Mayo Clinic staffFactors that increase your risk of contracting trachoma include:
- Poverty. Trachoma is primarily a disease of extremely poor populations.
- Crowded living conditions. Families living in close contact are at greater risk of spreading infection.
- Poor sanitation. Poor hygienic conditions facilitate spread of the disease.
- Age. In areas where the disease is endemic, it's most common in children ages 3 to 5.
- Sex. Women contract the disease at higher rates than men do. Women are also blinded up to four times more often than men are.
- Poor access to water. Households at greater distances from a water supply are more susceptible to infection.
- Flies. People living in areas with problems controlling the fly population may be more susceptible.
- Lack of latrines. Populations without access to working latrines have a higher incidence of the disease.
