ABSTRACT
Background Persons experiencing homelessness (PEH) suffer a high burden of chronic diseases and multi-morbidity, yet face significant barriers in accessing healthcare services. These health inequalities were further aggravated during the COVID-19 pandemic. While there is a lack of comprehensive health data on PEH, even less is known about populations experiencing housing exclusion, a hidden form of homelessness. This study examines and compares chronic diseases and multi-morbidity in PEH, persons experiencing housing exclusion, and persons with secure housing who lacked access to regular healthcare services in the wake of the COVID-19 pandemic in Germany.Methods Study participants were adults who sought medical care at clinics of the humanitarian organisation “Ärzte der Welt” in Munich, Hamburg and Berlin in 2020. The patients were categorised into three housing groups according to the ETHOS classification of homelessness and housing exclusion. Socio-demographic characteristics, self-rated health, chronic diseases, multi-morbidity and SARS-COV-2 rates were described in each group. Logistic regression analysis was used to identify socio-demographic factors associated with higher odds of chronic diseases and multi-morbidity in each housing group.Results Of the 695 study participants, 333 experienced homelessness, 292 experienced housing exclusion and 70 had secure housing. 92.3% of all patients had either no or limited health coverage, and 96.7% were below the poverty line. Males and EU/EEA citizens were highly represented among PEH (74.2% and 56.8% respectively). PEH had lower self-rated health (47.8%, p = 0.04), and higher rates of psychiatric illness (20.9%, p = 0.04). In adjusted analyses, belonging to the age group 35–49 and ≥ 50 years were associated with greater odds of chronic disease (AOR = 2.33, 95% CI = 1.68–3.24; AOR = 3.57, 95% CI = 2.55–5.01, respectively) while being male was associated with lower odds of multi-morbidity (AOR = 0.602, 95% CI = 0.38–0.9). Of the 18 symptomatic participants tested for SARS-COV-2, 15 were PEH, 1 of whom tested positive.Conclusions Housing status was not an independent risk factor for chronic disease and multi-morbidity in our study population. However, PEH reported poorer self-rated and psychiatric health. Strategies to improve access to healthcare services amongst persons experiencing homelessness and housing exclusion are needed in Germany.

COVID-19ABSTRACT
Background: In the 2nd year of the Covid-19 pandemic, knowledge about the dynamics of the infection in the general population is still limited. Such information is essential for health planners, as many of those infected show no or only mild symptoms and thus, escape the surveillance system. We therefore aimed to describe the course of the pandemic in the Munich general population living in private households from April 2020 to January 2021. Methods: The KoCo19 baseline study took place from April to June 2020 including 5313 participants (age 14 years and above). From November 2020 to January 2021, we could again measure SARS-CoV-2 antibody status in 4,433 of the baseline participants (response 83%). Participants were offered a self-sampling kit to take a capillary blood sample (dry blood spot; DBS). Blood was analysed using the Elecsys(R) Anti-SARS-CoV-2 assay (Roche). Questionnaire information on socio-demographics and potential risk factors assessed at baseline was available for all participants. In addition, follow-up information on health-risk taking behaviour and number of personal contacts outside the household (N=2768) as well as leisure time activities (N=1263) were collected in summer 2020. Results: Weighted and adjusted (for specificity and sensitivity) SARS-CoV-2 sero-prevalence at follow-up was 3.6% (95% CI 2.9-4.3%) as compared to 1.8% (95% CI 1.3-3.4%) at baseline. 91% of those tested positive at baseline were also antibody-positive at follow-up. While sero-prevalence increased from early November 2021 to January 2021, no indication of geospatial clustering across the city of Munich was found, although cases clustered within households. Taking baseline result and time to follow-up into account, men and participants in the age group 20-34 years were at the highest risk of sero-positivity. In the sensitivity analyses, differences in health-risk taking behaviour, number of personal contacts and leisure time activities partly explained these differences. Conclusion: The number of citizens in Munich with SARS-CoV-2 antibodies was still below 5% during the 2nd wave of the pandemic. Antibodies remained present in the majority of baseline participants. Besides age and sex, potentially confounded by differences in behaviour, no major risk factors could be identified. Non-pharmaceutical public health measures are thus still important.

COVID-19ABSTRACT
Background: Population-based studies investigating the dynamics of the SARS-CoV-2 pandemic are needed. Here, we report on baseline findings from April through June 2020 of a prospective cohort study in Munich, Germany.Methods: We drew a representative sample of 2994 private households. The 5313 participating household members 14 years and older completed questionnaires and provided blood samples. SARS-CoV-2 seropositivity was defined as Roche N pan-Ig ≥ 0·4218. We adjusted the prevalence for the sampling design, sensitivity, and specificity. We investigated risk factors for SARS-CoV-2 seropositivity and geospatial transmission patterns by generalized linear mixed models and permutation tests.Findings: Seropositivity for SARS-CoV-2 specific antibodies was 1·82% (95% confidence interval (CI) 1·28-2·37%) as compared to 0·46% PCR-positive cases officially registered in Munich. Loss of the sense of smell or taste was associated with seropositivity (odds ratio (OR) 47·4; 95% CI 7·2-307·0) and infections clustered within households. Participants suffering from respiratory allergies (OR 2·7; 95% CI 0·9-8·6) and working in high-risk jobs (OR 2·0; 95% CI 0·5-6·7) showed non-significantly increased odds for SARS-CoV-2 seropositivity.Interpretation: Applying a validated assay, we demonstrate a low SARS-CoV-2 seroprevalence in the Munich population 14 years and older towards the end of the first pandemic wave. However, we noted official sub-registration at this early stage of the pandemic.Funding: Bavarian State Ministry of Science and the Arts, University Hospital of LMU Munich, Helmholtz Centre Munich, University of Bonn, and University of Bielefeld.Declaration of Interests: FF, TF, DM, LO, and VT report grants from the Bavarian State Ministry of Science and the Arts during the conduct oft he study.
