Hypothesis
What is the prevalence of trachoma and its impact on visual impairment in Mankien payam, Southern Sudan?
Conclusion
Trachoma is a serious public health problem in Mankien, with a high prevalence of trichiasis, especially in children.
Supporting Evidence
- The prevalence of active trachoma in children aged 1–9 years was 63.3%.
- 9.6% of the sample population had trichiasis.
- The study found a high prevalence of trachoma-related corneal opacity at 7.3%.
- An estimated 5,344 persons in Mankien require trichiasis surgery.
Takeaway
Trachoma is a disease that can make people go blind, and many kids in Southern Sudan are affected by it, so we need to help them get treatment.
Methodology
A population-based cross-sectional survey with two-stage cluster random sampling was conducted.
Potential Biases
The random walk method for household selection may have introduced bias in estimating trachoma prevalence.
Limitations
The study may have overestimated the prevalence of trachoma due to absentees being more likely not to have the condition.
Participant Demographics
The sample included 3,567 persons, with 2,017 children under 15 years and 1,550 adults.
