BACKGROUND Pneumococcal disease is a leading cause of morbidity and mortality worldwide. The aim of this study was to investigate the association between specific pneumococcal serotypes and mortality from invasive pneumococcal disease (IPD). METHODS AND FINDINGS In a nationwide population-based cohort study of IPD in Denmark during 1977-2007, 30-d(More)
To study the natural history of rotavirus infection and to determine the protection it confers against reinfection and diarrhea, 200 newborns in Guinea-Bissau were prospectively followed for up to 2 years. Rotavirus was detected in stool specimens collected weekly. By age 2 years, the incidence of primary rotavirus infection was 74%. In the first 3 months(More)
BACKGROUND The impact of the 13-valent pneumococcal conjugate vaccine (PCV13) at the population level is unclear. We explored PCV13's effect in reducing invasive pneumococcal disease (IPD)-related morbidity and mortality, and whether serotype-specific changes were attributable to vaccination or expected as a part of natural, cyclical variations. METHODS(More)
BACKGROUND Pneumonia is among the main causes of illness and death in children <5 years of age. There is a need to better describe the epidemiology of viral community-acquired pneumonia (CAP) in developing countries. METHODS From July 2004 to June 2007, we examined nasopharyngeal aspirates (NPA) from 2,230 cases of pneumonia (World Health Organization(More)
Since 2008, annual surveys of influenza vaccination policies, practices and coverage have been undertaken in 29 European Union (EU)/ European Economic Area (EEA) countries. After 2009, this monitored the impact of European Council recommendation to increase vaccination coverage to 75% among risk groups. This paper summarises the results of three seasonal(More)
Diarrhoea is an important cause of death and illness among children in developing countries; however, it remains controversial as to whether diarrhoea leads to stunting. We conducted a pooled analysis of nine studies that collected daily diarrhoea morbidity and longitudinal anthropometry to determine the effects of the longitudinal history of diarrhoea(More)
BACKGROUND Pneumococcal infections have historically played a major role in terms of morbidity and mortality. We explored historical trends of invasive pneumococcal disease (IPD) and pneumococcal serotypes in a population exposed to limited antibiotic selective pressure and conjugate pneumococcal vaccination (PCV). METHODS Retrospective cohort study based(More)
We recruited 200 children shortly after birth and collected stool specimens weekly, irrespective of whether the children had diarrhea, until up to 2 years of age. All children were recruited during the first year of the study and were monitored for a median of 18.4 months. To measure pathogenicity, the odds ratio for diarrhea, adjusted for age, sex, and(More)
We evaluated the effectiveness of the heptavalent pneumococcal conjugate vaccine (PCV7) on invasive pneumococcal disease (IPD) 1 year after PCV7's introduction in the childhood immunization programme through a nationwide cohort study based on laboratory surveillance data. There was a decline in the overall incidence of IPD from 19.4 to 17.1 cases per(More)
Query (Q) fever was virtually unknown in Denmark in 2005, when, after the introduction of new sensitive diagnostic methods for Coxiella burnetii, an increasing number of positive cattle created concern among people with frequent exposure. This led to a dramatic rise in examinations for Q fever among humans in the following 2 years. The aim of our study was(More)
