摘要
Chronic Hepatitis B is a highly prevalent disease worldwide and is estimated to cause more than 800000 annual deaths from complications such as cirrhosis and hepatocellular carcinoma(HCC).Although universal hepatitis B vaccination programs may have reduced the incidence and prevalence of chronic hepatitis B and related HCC,the disease still imposes a significant healthcare burden in many endemic regions such as Africa and the Asia-Pacific region.This is especially concerning given the global underdiagnosis of hepatitis B and the limited availability of vaccination,screening,and treatment in low-resource regions.Demographics including male gender,older age,ethnicity,and geographic location as well as low socioeconomic status are more heavily impacted by chronic hepatitis B and related HCC.Methods to mitigate this impact include increasing screening in high-risk groups according to national guidelines,increasing awareness and health literacy in vulnerable populations,and developing more robust vaccination programs in under-served regions.
