Comparing susceptibility and contagiousness in concurrent outbreaks with a non-VOC and the VOC SARS-CoV-2 variant B.1.1.7 in daycare centers in Hamburg, Germany.

We describe two outbreaks of SARS-CoV-2 in daycare centers in the metropolitan area of Hamburg, Germany. The outbreaks occurred in rapid chronological succession, in neighborhoods with a very similar sociodemographic structure, thus allowing for cross-comparison of these events. We combined classical and molecular epidemiologic investigation methods to study infection entry, spread within the facilities, and subsequent transmission of infections to households. Epidemiologic and molecular evidence suggests a superspreading event with a non-variant of concern (non-VOC) SARS CoV-2 strain at the root of the first outbreak. The second outbreak involved two childcare facilities experiencing infection activity with the variant of concern (VOC) B.1.1.7 (Alpha). We show that the index cases in all outbreaks had been childcare workers, and that children contributed substantially to secondary transmission of SARS-CoV-2 infection from childcare facilities to households. The frequency of secondary transmissions in households originating from B.1.1.7-infected children was increased compared to children with non-VOC infections. Self-reported symptoms, particularly cough and rhinitis, occurred more frequently in B.1.1.7-infected children. Especially in light of the rapidly spreading VOC B.1.617.2 (Delta), our data underline the notion that rigorous SARS-CoV-2 testing in combination with screening of contacts regardless of symptoms is an important measure to prevent SARS-CoV-2 infection of unvaccinated individuals in daycare centers and associated households.

[Health Care for Refugees: Challenges and Opportunities in Hamburg]. / Medizinische Versorgung von Flüchtlingen: Chancen und Herausforderungen in Hamburg ­ ein Praxisbericht.

The massive increase in the number of refugees represents a great challenge to German cities. In Hamburg, 40 868 asylum seekers were registered in 2015, of which 22 315 remained in the city. The goal of the health administration is to provide primary medical care in response to specific health risks and needs of refugees while allowing them to be swiftly integrated into the standard health care system. Public authorities, charities and civil society are working hand in hand. In all reception centres in Hamburg, medical consultations with translation services are offered in fully equipped medical container practices. For every 1 000 refugees, a full-time doctor and a medical assistant are available. In addition to contractual staff, employees of contractually integrated hospitals are participating in the provision of medical care. Systematic collection of data on the health condition of the refugees as well as strengthening public health services are key factors in the planning and improvement of services in the future. Healthier living conditions and access to the standard health care system provide an opportunity to facilitate successful integration of refugees into society.

Defining and Assessing Public Health Functions: A Global Analysis.

Given the broad scope and intersectoral nature of public health structures and practices, there are inherent difficulties in defining which services fall under the public health remit and in assessing their capacity and performance. The aim of this study is to analyze how public health functions and practice have been defined and operationalized in different countries and regions around the world, with a specific focus on assessment tools that have been developed to evaluate the performance of essential public health functions, services, and operations. Our review has identified nearly 100 countries that have carried out assessments, using diverse analytical and methodological approaches. The assessment processes have evolved quite differently according to administrative arrangements and resource availability, but some key contextual factors emerge that seem to favor policy-oriented follow-up. These include local ownership of the assessment process, policymakers' commitment to reform, and expert technical advice for implementation.

The governments' doctors: the roles and responsibilities of chief medical officers in the European Union.

The regular meetings of the chief medical officers (CMOs) from the European Union's (EU's) 27 Member States provide an important forum to address issues of common interest affecting Europe's populations. Yet there is no universally agreed role for a CMO. This article describes the findings of a study, based on interviews with key informants and documentary analysis that sought to describe their diverse roles. For the purpose of this article, CMOs are defined as those sent by their governments to the regular EU meetings of CMOs. Four broad categories of countries were identified: those whose CMO is the most senior doctor in the health ministry, in some cases with responsibility spanning all of government; where they are head of a division within the health ministry; head of a separate body such as a national board of health; and countries where no single individual can be identified. Although the diversity of health systems means that these roles cannot be harmonised, there is scope to explore what can be learnt from the different approaches.
