Hepatitis B infection is a major global health burden, which, if left untreated, can lead to liver cirrhosis, hepatocellular carcinomas (HCC), and death. There are an estimated 248 million people living with chronic hepatitis B and the number continues to rise. Only 10.5% of those with hepatitis B virus (HBV) were thought to be aware of their status in 2016. WHO has called for its elimination as a public health threat by 2030.

The objective of this study is to use point-of-care diagnostics in community and faith-based settings to identify and link to care African (Ghanaian and Senegalese who are living in the greater Barcelona area) migrants living with HBV. Specifically, this pilot study utilizes a novel rapid diagnostic test to screen for HBsAg, the dried plasma spot testing method to collect blood samples and transport them to the laboratory, and will offer decentralized vaccination when appropriate for those who do not already have immunity.

Participants are screened in community centers on a pre-determined day arranged through community health agents. Before the screening process, an information session on HBV is provided by the community health agents, including the use of the HeparJoc interactive tool co-created with migrant populations.

Positive cases are provided with referrals to one of the two collaborating university hospitals in Barcelona during this first visit, irrespective of their viral load, for confirmation of infection and treatment initiation if applicable. Negative cases are provided their results during a second visit on average three weeks after the initial screening. Those who are negative and with no resolved past infection are offered the first-dose of the HBV vaccine in situ, with a referral for the subsequent doses at their corresponding primary care centers.

The project was launched in November 2020 and is led by ISGlobal in collaboration with west African community members, Hospital Clínic de Barcelona, Hospital Universitari Vall d'Hebron, the Health Department of the Generalitat de Catalunya, the Public Health Agency of Barcelona, and the Microbiology Department of the Vall d'Hebron Research Institute (VHIR).
