2. Summary
A serum samples were collected from African immigrants coming from North and Sub-Saharan Africa resided in Tripoli-Libya ( )
The total anti-core antibodies (anti-HBc), the surface antigen (HBsAg) and the protective anti-surface antigen antibodies (anti-HBs) were measured using immunoenzymatic assays .
The data was correlated with demographic and potential risk factors within the recruited individuals.

Provide a summary of your main findings, and the major relevant points. If possible, include an image that illustrates your research.

3. Why this study is important ?
A rare study highlighting the status HBV infections among immigrants before the final settlement in EU countries
The study could be used as a vehicle for further understanding to the epidemiology of HBV in African countries which rarely studied.
This is more likely to influence EU countries health care system regarding viral screening and guide lines HIV infection
Explain the importance and relevance of your research, putting it in context.

4. Background
Sub-Saharan Africa have been considered to harbor the highest prevalence of HIV.
Mass migration has been on the upswing in recent years particularly from North and sub-Saharan Africa.
HBV infections among African immigrants are rarely studied particularly before resettlement.
The study aimed to determine 1-the prevalence of HBV among African immigrants gather in Libya on their way to Europe 2- HBV-HIV-HCV coinfection and genotypes among HIV infected immigrants and its correlation different demographic factors.

Talk through your results – what stood out? What surprised you?

7. Continue to describe your results on this second slide if you need more time.

8. Concepts and future steps
A higher prevalence of HBV and HIV-HCV co-infections with distinct variation among immigrants.
Further studies on following up the epidemiology of HBV among immigrants during final resettlement are needed.
Neoliberal policies of HBV prevention should be introduced and extended beyond the European borders to reach Africa
