Cross-Sectional Study on Influenza Vaccination, Germany, 1999–2000

To assess influenza vaccination coverage in Germany, we conducted a nationwide telephone survey in November 1999 in adults (>18 yrs) using random-digit dialing. Overall, 23% of 1,190 survey participants reported having been vaccinated (adjusted 18%) with 16% (adjusted 15%) in former West Germany versus 35% (adjusted 32%) in former East Germany. Immunization rates for vaccination target groups were lower in West Germany (21%) than in East Germany (40%). Seven percent of health-care workers were immunized. Previous influenza vaccination, positive attitudes towards immunization, and having a family physician increased the rate of vaccination; fear of adverse effects lowered the rate. Family physicians performed 93% of the vaccinations, which suggests their key role in improving low vaccination coverage in Germany. The fact that >71% (850/1,190) of participants belonged to at least one of the vaccination target groups recommended by the German Standing Commission on Immunization emphasizes the need to focus the definition of target groups

Influenza activity in Cambodia during 2006-2008

<p>Abstract</p> <p>Background</p> <p>There is little information about influenza disease among the Cambodian population. To better understand the dynamics of influenza in Cambodia, the Cambodian National Influenza Center (NIC) was established in August 2006. To continuously monitor influenza activity, a hospital based sentinel surveillance system for ILI (influenza like illness) with a weekly reporting and sampling scheme was established in five sites in 2006. In addition, hospital based surveillance of acute lower respiratory infection (ALRI) cases was established in 2 sites.</p> <p>Methods</p> <p>The sentinel sites collect weekly epidemiological data on ILI patients fulfilling the case definition, and take naso-pharyngeal specimens from a defined number of cases per week. The samples are tested in the Virology Unit at the Institut Pasteur in Phnom Penh. From each sample viral RNA was extracted and amplified by a multiplex RT-PCR detecting simultaneously influenza A and influenza B virus. Influenza A viruses were then subtyped and analyzed by hemagglutination inhibition assay. Samples collected by the ALRI system were tested with the same approach.</p> <p>Results</p> <p>From 2006 to 2008, influenza circulation was observed mainly from June to December, with a clear seasonal peak in October shown in the data from 2008.</p> <p>Conclusion</p> <p>Influenza activity in Cambodia occurred during the rainy season, from June to December, and ended before the cool season (extending usually from December to February). Although Cambodia is a tropical country geographically located in the northern hemisphere, influenza activity has a southern hemisphere transmission pattern. Together with the antigenic analysis of the circulating strains, it is now possible to give better influenza vaccination recommendation for Cambodia.</p

Mass gathering events and undetected transmission of SARS-CoV-2 in vulnerable populations leading to an outbreak with high case fatality ratio in the district of Tirschenreuth, Germany

In early March 2020, a COVID-19-outbreak occurred in the district of Tirschenreuth, Germany. The outbreak was characterised by a rapid increase in case numbers and a comparatively high crude case fatality ratio (CFR; 11%). Until the beginning of May 2020, 1122 cases were reported in the district. To investigate the outbreak, we analysed surveillance and other data available at the district health department, including data on cases living in care facilities and public health measures applied. Furthermore, we compared the number of tests performed in Tirschenreuth and in Germany as a whole. We interviewed the first 110 cases in order to investigate potential exposures at the beginning of the outbreak. We found that returning ski-travellers from Austria and Italy and early undetected community transmission likely initiated the outbreak which was then accelerated by Bavarian beer festivities. Testing of mainly acute cases in the district of Tirschenreuth resulted in a higher rate of positive tests compared to the whole of Germany. Despite adjustment for age, the CFR continued to exceed the German mean which was due to spread to vulnerable populations. Strict public health measures likely contributed to control the outbreak by mid-April 2020

Kontrolle eines COVID-19-Ausbruches im Landkreis Tirschenreuth, März bis Mai 2020

Die vorgestellten Analysen beruhen auf den vom Gesundheitsamt Tirschenreuth an das RKI übermittelten Meldedaten und machen den hohen Stellenwert deutlich, den diese Daten an der Aufklärung von Ausbruchsgeschehen haben. Die Untersuchungen zeigen, dass SARS-CoV-2 ohne effiziente Kontrollmaßnahmen zu großen Ausbrüchen mit hoher Fallsterblichkeit unter Risikogruppen und in Pflege- und Altenheimen führen kann. Kontrollmaßnahmen sind daher unabdingbar und bedürfen eines gut aufgestellten ÖGD, der Kooperationsbereitschaft der Bevölkerung und eines belastbaren Gesundheitssystems, das Erkrankte versorgen und nosokomiale Ausbrüche verhindern kann

Developing pandemic preparedness in Europe in the 21st century: experience, evolution and next steps

PROBLEM: Improving pandemic planning and preparedness is a challenge in Europe, a diverse region whose regional bodies (the Regional Office for Europe of the World Health Organization [WHO], the European Commission and the European Centre for Disease Prevention and Control) have overlapping roles and responsibilities. APPROACH: European pandemic preparedness indicators were used to develop an assessment tool and procedure based on the 2005 global WHO checklist for pandemic preparedness. These were then applied to Member States of WHO's European Region, initially as part of structured national assessments conducted during short visits by external teams. LOCAL SETTING: Countries in WHO's European Region. RELEVANT CHANGES: From 2005 to 2008, 43 countries underwent a pandemic preparedness assessment that included a short external assessment visit by an expert team. These short visits developed into a longer self-assessment procedure involving an external team but "owned" by the countries, which identified gaps and developed plans for improving preparedness. The assessment tool and procedure became more sophisticated as national and local pandemic preparedness became more complex. The 2009 pandemic revealed new gaps in planning, surveillance communications and immunization. LESSONS LEARNT: Structured national self-assessments with support from external teams allow individual countries to identify gaps in their pandemic preparedness plans and enable regional bodies to assess the regional and global resources that such plans require. The 2009 pandemic revealed additional problems with surveillance, pandemic severity estimates, the flexibility of the response, vaccination, involvement of health-care workers and communication. European national plans are being upgraded and global leadership is required to ensure that these plans are uniformly applied across the region

Actions for prevention and control of health threats related to maritime transport in European Union

Background: Actions at European Union level for International Health Regulations (IHR) 2005 implementation and maritime transport were focused on two European projects implemented between 2006 and 2011. Method: Situation analysis and needs assessment were conducted, a Manual including European standards and best practice and training material was developed and training courses were delivered. Ship-to-port and port-to-port communication web-based network and database for recording IHR Ship Sanitation Certificates (SSC) were established. Results: Fifty pilot inspections based on the Manual were conducted on passenger ships. A total of 393 corrective actions were implemented according to recommendations given to Captains during pilot inspections. The web-based communication network of competent authorities at ports in EU Member States was used to manage 13 events/outbreaks (dengue fever, Legionnaires’ disease, gastroenteritis, meningitis, varicella and measles). The European information database system was used for producing and recording 1018 IHR SSC by 156 inspectors in 6 countries in accordance with the WHO Handbook for inspection of ships and issuance of SSC. Conclusions: Implementation of corrective actions after pilot inspections increased the level of compliance with the hygiene standards in passenger ships sailing within the EU waters and improved hygiene conditions. The communication tool contributed to improvement of outbreak identification and better management through rapid sharing of public health information, allowing a more timely and coordinated response. After the implementation of actions on passenger ships, the European Commission co-funded a Joint action that will expand the activities to all types of ships and chemical, biological and radio-nuclear threats (deliberate acts/accidental).

Untersuchung von SARS-CoV-2-Ausbrüchen in Deutschland durch Feldteams des Robert Koch-Instituts, Februar–Oktober 2020

The Robert Koch Institute (RKI) offers advice and assistance to local public health agencies on the investigation and management of outbreaks of infectious diseases. Specially trained experts conduct field investigations. During the COVID-19 pandemic, RKI experts participated in the investigation of outbreaks in residential buildings, physicians' offices, nursing homes, hospitals, and asylum seekers' facilities as well as at a night club and on a cruise ship.This report describes some of the field investigations conducted in Germany during the COVID-19 pandemic between February and October 2020. The investigations provided information on the properties of SARS-CoV‑2 and its transmission as a basis for the recommendations on suitable prevention measures. The practical examples demonstrate the variety of support given as well as the opportunities to gather epidemiological evidence.In September 2020, the RKI established a new unit called the 'Focal Point for the Public Health Service,' which now coordinates and is expanding field support. In order to further support the public health system to improve its capability to react to and investigate outbreaks of infectious diseases, interdisciplinary training shall be intensified
