Abstract:
Objective To study the characteristics of hepatitis B before and after hepatitis B vaccine was included in the immunization program in Haidong area, and to provide basis for the prevention and control strategy of hepatitis B. Methods The annual incidence of hepatitis B before (2000 -2002) and after (2018 -2020) hepatitis B vaccine was analyzed by descriptive epidemiological method from the hepatitis B cases reported by the notifiable infectious diseases reporting system and hepatitis B surveillance system in Haidong region. After the hepatitis B vaccine was included in the immunization program, the experimental group was used to analyze the characteristics of hepatitis B disease before and after the hepatitis B vaccine was included in the immunization program, including age, sex, region, occupation and season of onset. A certain number of people were randomly selected to compare the vaccination rate of hepatitis B vaccine before and after inclusion in the immunization program. Results The incidence of hepatitis B increased year by year before hepatitis B vaccine was included in the immunization program, but decreased year by year after hepatitis B vaccine was included in the immunization program, and the difference between the two groups was statistically significant (P<0.05). There was no significant difference between the two groups ( P>0.05). Before and after the introduction of hepatitis B vaccine into the immunization program, the incidence of hepatitis B mainly concentrated in 20 to 60 years old, 0 to 19 years old, the lowest incidence, there was no statistical significance between the two groups (P>0.05). The incidence of hepatitis B vaccine in males was higher than that in females before and after hepatitis B vaccine was included in the immunization program, and there was no statistical significance between the two groups (P>0.05). The incidence of hepatitis B in urban areas was higher than that in rural areas before hepatitis B vaccine was included in the immunization program, and the incidence of hepatitis B in rural areas was higher than that in urban areas after hepatitis B vaccine was included in the immunization program, with statistical significance (P<0.05). Before the introduction of hepatitis B vaccine into the immunization program, the incidence of hepatitis B mainly concentrated in farmers, the proportion of farmers increased from 50.99% to 53.31%, the proportion of students decreased from 5.38% to 2.56%, and the difference was statistically significant (P<0.05). After hepatitis B vaccine was included in the immunization program, the vaccination rate of hepatitis B vaccine increased from (93.61%) to (98.18%), and the difference between the two groups was statistically significant (P<0.05). Conclusion The hepatitis B vaccine in Haidong area has achieved remarkable effect and effectively controlled the incidence of hepatitis B.
