Objective To understand the prevalence and epidemiological characteristics of hepatitis B in Jiaocheng County and provide a scientific basis for formulating and improving prevention and control strategies. Methods Descriptive epidemiological methods were used to analyze the data of Hepatitis B outbreaks in Jiaocheng county from 2006 to 2012. Results A total of 3 109 cases of hepatitis B were reported in Jiaocheng county from 2006 to 2012, with an average annual incidence of 197.41 / 100000 (3 109/1 376 897) and a male incidence of 235.62 / 100000 (1 884/799 576) , The incidence rate of females was 153.21 / 100000 (1 225/775 321), the sex ratio of males and females was 1.49:1. The highest incidence was found in the age group of 25-29 years old (420.24 / 100000), followed by the age group of 20-24 years (406.42 / 100000), the lowest incidence in the age group of 0-15 years (17.53 / 100000). The occupational composition of farmers is more (67.39%), followed by students (7.85%). Conclusion The incidence of Hepatitis B in Jiaocheng County is mainly dominated by young male farmers, and also has a high incidence among students. Hepatitis B vaccine vaccination should be further raised in key populations. In rural areas, schools should step up publicity and education on health to reduce the incidence of hepatitis B.
