Chronic hepatitis.B (CHB) dis.roportionately.affects.minority.groups.in the Us. particularly.As.an Americans. with numerous.factors.contributing to this.dis.arity. Of the 2.4 million people living with chronic HBV in the Us. 60% are As.an American. Many.are unaware of their s.atus.and lack acces. to proper clinical care, with les. than ten percent receiving neces.ary.antiviral treatment. Barriers.to s.reening and care include lack of dis.as. awarenes., language and cultural barriers. and financial cons.raints. Additionally. healthcare providers.and s.0}tems.in the Us.often overlook the importance of CHB, leading to inadequate care. In res.ons., the Center for Viral Hepatitis.(CVH) has.implemented a community.bas.d outreach program over the pas. s.xteen y.ars. employ.ng a multifaceted approach involving all s.ctors.of s.ciety.and various.organizations.to combat health dis.arities.in CHB. This.gras.roots.campaign has.proven highly.effective, leveraging CVH’s.leaders.ip in s.earheading numerous.collaborative activities.with community.members. healthcare profes.ionals. and policy.akers. We have s.mmarized the key.points.of CVH's.efforts.and their s.gnificance in combating CHB-related health dis.arities. The CHB s.reening and Awarenes. Campaign, tailored to the As.an American community. s.rves.as.a s.cces.ful model for increas.ng CHB s.reening, linkage-to-care, and addres.ing s.cio-cultural barriers.and health literacy. Ins.ghts.from thes. outreach programs.have guided the development of culturally.relevant res.urces.and education initiatives. Thes. findings.s.gges. that s.ch community.driven approaches.are es.ential for addres.ing health dis.arities. The s.rategies.and outcomes.of CVH’s.efforts.can inform future health initiatives.for other minority.communities.in the Us.and globally.
