Three months after a coronavirus disease (COVID-19) outbreak in Kupferzell, Germany, a population-based study (n = 2,203) found no RT-PCR-positives. IgG-ELISA seropositivity with positive virus neutralisation tests was 7.7% (95% confidence interval (CI): 6.5–9.1) and 4.3% with negative neutralisation tests. We estimate 12.0% (95% CI: 10.4–14.0%) infected adults (24.5% asymptomatic), six times more than notified. Full hotspot containment confirms the effectiveness of prompt protection measures. However, 88% naïve adults are still at high COVID-19 risk.

Background Among all newly diagnosed HIV cases in Germany in 2015, 16% originated from sub-Saharan Africa. Twelve percent of these infections were contracted within Germany and migrants from sub-Saharan Africa (misSA) are diagnosed later than Germans. Migrants, specifically those without health insurance, face many barriers accessing health care due to their residence status and cultural, socio-economic, legal and linguistic barriers. We assessed whether misSAs’ access to healthcare and utilization of HIV testing services depends on their health insurance status to inform prevention strategies. Methods From January 2015 to February 2016, we conducted a cross-sectional survey on knowledge, attitude, behavior, practice (KABP) regarding HIV, viral hepatitis and sexually transmitted infections among misSA in Germany. The survey was a community-based participatory research project; trained peer researchers recruited participants through outreach. To detect differences between participants with a regular health insurance card compared to asylum seekers with a medical treatment voucher or participants without health insurance or medical treatment voucher, unadjusted and adjusted Odds Ratios, chi-squared tests and 95% confidence intervals were calculated. Results A total of 1919 cases were considered. Overall, 83% had a health insurance card, 10% had a medical treatment voucher and 6% had no health insurance. Participants living in Germany for less than 5 years were less likely to have a health insurance card and more likely to have lower German language skills. Participants without health insurance visited a physician in case of health problems less often than participants with medical treatment voucher or a health insurance card (41.2% vs. 66.1% vs. 90%). Participants without health insurance reported less frequently visiting physicians or hospitals and were less likely to undergo a HIV test. Conclusion Having no health insurance or medical treatment voucher decreased the odds of contact with the healthcare system more than other socio-demographic characteristics. Furthermore, misSA without health insurance had lower odds of ever having done an HIV test than participants with health insurance. To increase health care utilization and testing and to ensure adequate medical care, all migrants should get access to health insurance without increasing costs and consequences for residence status.

BackgroundMigrants from sub-Saharan Africa (MisSA) are a relevant sub-group for HIV-transmission in Germany. A total of 10-15 % of all newly diagnosed cases are MisSA, and approximately one third acquired HIV in Germany. There is limited information on knowledge, attitudes, behaviors and practices (KABP) regarding sexual health in African communities residing in Germany.MethodsFrom October-December 2013 we conducted a cross-sectional survey on KABP regarding HIV, viral hepatitis (HEP), and sexually transmitted infections (STI) among MisSA in Hamburg as a community-based participatory research project to identify knowledge gaps, sexual risk behavior regarding HIV/HEP/STI, HIV/STI-testing history and attitudes toward people living with HIV (PLWH). Trained peer researchers recruited participants through outreach. Questionnaires in German, English or French were either administered face-to-face or self-completed. Questions on knowledge about HIV/HEP/STI presented true statements; participants were asked if they knew the information before. To detect differences in sub-groups, unadjusted odds ratios (OR) were calculated, and a multivariate analysis for knowledge on HIV/HEP/STI was performed.ResultsThe final sample included 569 participants of whom 57 % were men. Most participants originated from Western and Central sub-Saharan Africa. Median time living in Germany was 6 years. Overall, 28 % had a university degree and 54 % reported a good level of German language. Over 80 % knew the risks for HIV transmission. A total of 44 % of respondents wrongly assumed that an HIV-diagnosis might lead to deportation and 64 % were not aware of the free and anonymous local HIV/STI-testing service. The proportion of participants with knowledge of presented facts on HEP varied from 40-58 %. The respective proportion on STI was 28-68 % and better among women compared to men (44 % vs. 54 %; OR = 1.45; 95 % CI 1.22-1.74). Men reported more often casual sex partners than women (43 % vs. 23 %; OR = 2.6; 95 % CI 1.7-4.0), and more frequently a previous STI (58 % vs. 39 %; OR = 2.1; 95 % CI 1.1-4.1). Overall, 16 % of women reported a history of sexual violence. The majority of respondents (75 %) reported that they would treat PLWH like any other person.ConclusionStudy participants demonstrated good knowledge on HIV-transmission but knowledge gaps regarding HIV/STI-testing services, HEP and STI. This calls for targeted interventions providing more information about these topics in African communities in Hamburg and possibly also elsewhere.Electronic supplementary materialThe online version of this article (doi:10.1186/s12889-015-2098-2) contains supplementary material, which is available to authorized users.
