British Medical Journal
|March 25, 1978
Summary
This study found that scabies outbreaks in Sheffield were primarily introduced by schoolchildren and teenagers, with a significant 38% secondary attack rate within households. Public health interventions like case notification and contact tracing are crucial for controlling scabies epidemics.
Area of Science:
- Epidemiology
- Dermatology
- Public Health
Background:
- Scabies outbreaks can pose a significant public health challenge.
- Understanding transmission dynamics is key to effective control strategies.
Purpose of the Study:
- To investigate the epidemiology of a scabies outbreak in Sheffield.
- To identify key transmission routes and risk factors.
Main Methods:
- Retrospective case review from June 1972 to May 1973.
- Inclusion of all suspected scabies cases referred to a hospital skin department.
- Contact tracing conducted by a trained nurse.
Main Results:
- 1482 cases identified across 609 households, a tenfold increase from 1971.
- Schoolchildren and teenagers, particularly girls, were primary introduction sources.
- Secondary attack rate within households reached 38%.
Conclusions:
- Household transmission is a major factor in scabies spread.
- Contact tracing and prompt treatment are vital for outbreak control.
- Public health initiatives are recommended to manage the ongoing scabies epidemic.
