[A prospective study of dynamic and epidemic factor of HBV infection in the army]
1PLA General Logistics Department.
Insights
This study tracked 519 susceptible individuals in the army for five years, finding a Hepatitis B virus (HBV) cumulative infection rate of 16.12 per 1000 person-years. Managing asymptomatic carriers and patients is crucial for army health.
Area of Science:
- Epidemiology
- Infectious Diseases
- Public Health
Context:
- Hepatitis B virus (HBV) poses a significant risk in military populations due to close living conditions.
- Understanding HBV transmission dynamics within the army is essential for effective prevention strategies.
Purpose:
- To prospectively investigate the incidence and characteristics of HBV infection among susceptible army personnel.
- To identify factors associated with HBV infection risk in a military cohort.
Summary:
- A five-year prospective study observed 519 susceptible individuals, revealing a cumulative HBV infection rate of 16.12 per 1000 person-years.
- Latent infections constituted the majority, and while HBsAg positivity and contact history showed indirect correlations, they highlighted transmission pathways.
- The findings underscore the need for targeted management of asymptomatic Hepatitis B surface antigen (HBsAg) carriers and Hepatitis B (HB) patients within the army.
Impact:
- Provides critical data on HBV epidemiology in a unique, high-risk population.
- Informs public health policies and clinical management guidelines for HBV prevention in military settings.
- Highlights the importance of identifying and managing asymptomatic carriers to curb HBV spread in the army.
Abstract:
In order to study the HBV infection in the army a total of 519 HBV susceptibles were observed prospectively for five years. The results showed that the cumulative infection rate of HBV was 16.12/1000 person-years and the latent infection was in the majority. There are many factors that could affect army population, the rate of HBsAg positive and the contact history with HB patients were indirect correlation with the rate of new HBV infection. Therefore it is an urgent matter to manage asymptomatic HBsAg carriers and HB patients in the army.
