  1. 1. Norovirus Epidemiology : Prevalence, transmission, and determinants of disease susceptibility

    Författare :Johan Nordgren; Per-Eric Lindgren; Lennart Svensson; Andreas Matussek; Annalarua Carducci; Linköpings universitet; []
    Nyckelord :MEDICINE; MEDICIN;

    Sammanfattning : Norovirus (NoV) is today recognized as the most important agent of acute human gastroenteritis, causing a high number of diarrheal episodes in both adults and children. Outbreaks in hospitals, nursing homes, day-care centers, and from consumption of contaminated food and drinking water are common. Wastewater can be a source of NoV dissemination, e. LÄS MER

  3. 2. Norovirus and rotavirus susceptibility : studies from a Nicaraguan birth cohort

    Sammanfattning : Norovirus and rotavirus are major causes of pediatric acute gastroenteritis (AGE). It is estimated that norovirus is responsible for ~20% of all diarrheal diseases in children worldwide and causes approximately 200,000 deaths each year, mostly in young children and the elderly.

  4. 3. The Norovirus Puzzle : Characterization of human and bovine norovirus susceptibility patterns

    Författare :Malin Vildevall; Lennart Svensson; Anders Widell; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Virology; Virologi;

    Sammanfattning : Winter vomiting disease is caused by norovirus (NoV) and affects millions of people every year resulting in 200.000 deaths among children in developing countries. It was observed early that not all individuals exposed to the norovirus became ill. The reason for this is now recognized to be dependent upon the secretor status of an individual. LÄS MER

  5. 4. On norovirus outbreaks and transmission in hospitals

    Författare :Carl-Johan Fraenkel; Infektionsmedicin; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; norovirus; outbreaks; transmission; surveillance; prevention;

    Sammanfattning : Abstract Noroviruses are now the leading cause of gastroenteritis worldwide. Noroviruses are effectively transmitted due to a low infectious dose, viral shedding in high concentrations, environmental stability, and they induce only a limited immunity after infection. Especially, the norovirus variants of genotype II.4 (GII. LÄS MER

  7. 5. Norovirus Tracing in Environmental and Outbreak Settings - Experiences of waterborne, foodborne and nosocomial transmission

    Författare :Nancy P Nenonen; Göteborgs universitet; []

    Sammanfattning : Noroviruses (NoV), a major cause of acute gastroenteritis in hospital settings, also occur as sporadic infections or periodic non-seasonal community outbreaks. Human NoV replicates to high concentration in the intestinal tract, is readily transmitted by the faecal-oral route, hand-to-hand contact, contaminated food and water, and by aerosols. LÄS MER
