Trachoma

  • About:
    • It is the world’s leading infectious cause of blindness and is one of the conditions known as neglected tropical diseases.
    • It is a public health problem in 44 countries and is responsible for the blindness or visual impairment of about 1.9 million people. 
  • Origin and symptoms: 
    • Trachoma starts off as a bacterial infection and can be easily treated. 
    • Overtime, it causes the eyelashes to be pushed inwards into the eye. So with every blink, they brush against the eyeball.
    • This advanced form of trachoma is called trichiasis. Over time, if it’s not treated, trichiasis can lead to blindness.
  • Grows where: 
    • The disease thrives where there are water shortages, poor sanitation and infestations of flies, which are considered physical vectors of the disease.

Path to elimination – Global Trachoma Mapping Project 

  • About: It was launched to map 25 districts suspected of being trachoma-endemic.
  • The mapping survey aimed to: Determine the prevalence of active trachoma (TF) in 1-9-year-old children, and the prevalence of trachomatous trichiasis (TT) in adults aged 15 years and above.
