What is the prevalence of Trachoma?
Prevalence of Trachoma: how many people are affected worldwide, differences by sex and region, with sources.
Trachoma is a highly contagious eye infection caused by the bacterium Chlamydia trachomatis. It is a leading cause of preventable blindness worldwide, particularly in areas with limited access to clean water and sanitation facilities. Trachoma is prevalent in many developing countries, primarily in Africa, the Middle East, and parts of Asia and Latin America.
The World Health Organization (WHO) estimates that approximately 142 million people are affected by trachoma globally, with 1.9 million individuals experiencing severe visual impairment or blindness as a result of the disease. Trachoma is more common in rural communities where poverty, overcrowding, and inadequate hygiene practices contribute to its spread.
Efforts to combat trachoma have been underway for decades, focusing on the implementation of the SAFE strategy: Surgery for advanced cases, Antibiotics to treat active infection, Facial cleanliness, and Environmental improvements to reduce transmission. These interventions have significantly reduced the prevalence of trachoma in many regions, but the disease remains a public health concern in several areas.
Addressing trachoma requires sustained efforts in improving access to clean water, sanitation, and healthcare services, as well as promoting hygiene practices and community education. By prioritizing prevention and treatment, we can work towards eliminating trachoma as a public health problem and ensuring better eye health for all.
