Leprosy in Myanmar, epidemiological and operational changes, 1958-92
Leprosy Review
|March 1, 1996
Summary
Leprosy caseload and new case detection rates have significantly declined in Myanmar. Changes in case types and age groups suggest a potential decrease in leprosy incidence.
Area of Science:
- Epidemiology
- Public Health
- Infectious Diseases
Background:
- Leprosy (Hansen's disease) remains a significant public health concern globally.
- Monitoring disease trends is crucial for effective control strategies.
Purpose of the Study:
- To analyze trends in leprosy caseload, prevalence, and new case detection rates in Myanmar.
- To investigate changes in the characteristics of new leprosy cases over time.
Main Methods:
- Retrospective analysis of registered leprosy data in Myanmar.
- Examination of trends in prevalence, new case detection rates, multibacillary proportion, and age distribution of new cases.
Main Results:
- Registered leprosy caseload and prevalence per 10,000 population decreased from 86.2 (1973-77) to 26.82 (1988-92).
- New case detection rates declined from 7.41 (1968-72) to 1.96 (1988-92) per 10,000 population.
- Multibacillary leprosy proportion increased from 11.85% to 40.54%, while cases under 14 years decreased from 26.81% to 11.22%.
Conclusions:
- Observed declines in leprosy indicators suggest a potential reduction in disease incidence in Myanmar.
- Shifts in case demographics warrant further investigation into transmission dynamics and control program effectiveness.
