Leprosy in children: a retrospective study in China, 1986-1997
1National Center for STD and Leprosy Control, Institute of Dermatology, CAMS & PUMC, Nanjing, China.
Insights
Childhood leprosy in China decreased significantly between 1986-1997. While not a major public health issue, regular screening of children in leprosy patient families is recommended for early detection.
Area of Science:
- Epidemiology
- Pediatric infectious diseases
Background:
- Leprosy in children is crucial for understanding disease transmission and epidemic patterns.
- Childhood leprosy incidence has been declining in China.
Purpose of the Study:
- To analyze trends and characteristics of childhood leprosy in China from 1986-1997.
- To assess the public health significance of pediatric leprosy.
Main Methods:
- Retrospective analysis of 1208 child leprosy cases detected between 1986 and 1997 in China.
- Evaluation of detection rates, age-specific incidence, lesion types, and modes of transmission.
Main Results:
- Child cases represented 3-4% of total leprosy cases, with a dramatic decrease in incidence rates.
- Detection rates increased with age; pediatric incidence (0.027/100,000) was lower than adult incidence.
- Younger children had more solitary lesions and fewer reactions/disabilities compared to older children.
- Intra-familial contact was the primary source (70.01%), followed by contact examination (35.60%) and active surveys (22.86%).
Conclusions:
- Leprosy in children is currently not a significant public health problem in China.
- Regular screening of children within leprosy patient families is vital for early case detection and disease control.
Abstract:
Leprosy in children forms an important link in the natural evolution and the epidemic profile of the disease. The study was undertaken on 1208 child cases detected during the years 1986-1997 in China. The number of child cases constituted 3-4 per cent of the total during this period although the incidence rates decreased dramatically. The detection rate significantly increased with age, and the average rate of 0.027 per 100,000 population was much lower than that in adults. In the pediatric cases, children in the younger age group had a higher prevalence of solitary lesions and lower prevalence of reactions and disabilities than the older group. A total of 70.01 per cent of the affected cases were infected by intra-familial contact, 35.60 per cent were detected by contact examination, and another 22.86 per cent by active surveys. The results of the study suggest that leprosy in children is not a public health problem at the present in China, but the regular screening of children in the family of patients is still one of the important ways to detect child cases and should be recommended.
