Hypothesis
What is the prevalence of previously undiagnosed leprosy in the general population of northwest Bangladesh?
Conclusion
The prevalence of previously undiagnosed leprosy is six times higher than the registered prevalence in the area.
Supporting Evidence
- The previously undiagnosed leprosy rate was found to be 15.1 per 10,000 individuals.
- 27 new cases of leprosy were identified among the surveyed population.
- The prevalence of leprosy among contacts of leprosy patients was significantly higher than in the general population.
Takeaway
In northwest Bangladesh, many people have leprosy without knowing it, and we found that it's much more common than what was previously recorded.
Methodology
Multistage cluster sampling was used to examine 20 clusters of 1,000 people each, totaling 17,862 individuals over 5 years of age.
Potential Biases
Potential selection bias on individual level as those afraid of diagnosis may avoid participation.
Limitations
Selection bias may occur as only those present during the survey were included, and some individuals may have hidden due to stigma.
Participant Demographics
The study included individuals from two districts in northwest Bangladesh, with a total population of over 4 million.
