Trachoma FAQ
What causes trachoma?
Trachoma is caused by the bacterium Chlamydia trachomatis, which is highly contagious and spreads through direct or indirect contact with the eyes, nose, and throat secretions of infected individuals.
What are the symptoms of trachoma?
Early symptoms include irritation, discharge, and light sensitivity. Without treatment, trachoma can lead to progressive scarring of the eyelid, causing the eyelashes to turn inward and scratch the cornea, leading to vision loss.
How is trachoma diagnosed?
Trachoma is diagnosed through a physical exam of the eyes and the detection of characteristic signs such as inflammation, scarring, and the presence of follicles on the inner surface of the upper eyelid.
Is trachoma contagious?
Yes, trachoma is highly contagious, especially among children in crowded and unhygienic conditions. It can spread through personal contact, shared towels, and flies that have come into contact with an infected person.
How is trachoma treated?
Treatment usually involves oral antibiotics such as azithromycin, tetracycline, or erythromycin. Surgery may be required in advanced cases to correct eyelid deformities caused by scarring.
Can trachoma be prevented?
Preventive measures include promoting good hygiene, access to clean water, and facial cleanliness to reduce transmission. Mass treatment with antibiotics in affected communities can also help control the spread of trachoma.
Who is at risk of trachoma?
Trachoma is more common in areas with poor sanitation, limited access to healthcare, and crowded living conditions. Children, women, and people living in poverty are at a higher risk of developing trachoma.
Can trachoma lead to blindness?
Without timely treatment, trachoma can cause irreversible blindness due to corneal scarring. It is a leading cause of preventable blindness worldwide, particularly in low-resource settings.
Are there any complications associated with trachoma?
Chronic trachoma can lead to complications such as corneal ulceration, visual impairment, and decreased quality of life due to pain, discomfort, and difficulty performing daily activities.
How long does it take for trachoma to progress?
The progression of trachoma varies, but without treatment, the disease can advance over several years, leading to severe scarring and visual impairment, particularly in repeated or persistent infections.
Can trachoma affect both eyes?
Yes, trachoma can affect both eyes, and simultaneous treatment of both eyes is often necessary to prevent the spread of infection and minimize the risk of permanent vision loss.
What should I do if I suspect trachoma?
If you suspect trachoma, seek medical attention promptly. Early diagnosis and treatment can help prevent the progression of the disease and reduce the risk of complications, including vision loss.
Is there a vaccine for trachoma?
Currently, there is no licensed vaccine for trachoma. However, efforts to develop a vaccine are ongoing, focusing on targeting the bacterium Chlamydia trachomatis to prevent the transmission and development of the disease.
Is trachoma common in developed countries?
Trachoma is rare in developed countries with access to improved sanitation, healthcare, and hygiene practices. However, it remains prevalent in low-income regions with inadequate infrastructure and limited resources.
Can trachoma recur after treatment?
Yes, trachoma can recur, especially in areas where the disease is endemic and preventive measures are challenging to implement. Regular screening, treatment, and community-wide interventions are essential for controlling recurrences.
What impact does trachoma have on affected communities?
Trachoma has a significant impact on affected communities, contributing to poverty, social stigma, and reduced productivity due to the disability and economic burden associated with visual impairment and blindness.
