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

    Author : Nancy P Nenonen; Göteborgs universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Norovirus; tracing; environment; foodborne; outbreak; waterborne; nosocomial; mussels; GI.1; oysters; GII.4; dust; surfaces; air; molecular epidemiology;

    Abstract : 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. READ MORE

  4. 2. Univariate and Multivariate Surveillance of Outbreaks

    Author : Linus Schiöler; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; change-points; expected delay; exponential family; false alarms; generalised likelihood; inference principles; influenza; MEWMA; monitoring; multivariate; ordered regression; performance metrics; outbreak; predictive value; subjective judgment; spatial; statistical models; surveillance; tularemia;

    Abstract : In many areas there is a need to monitor observations in order to detect changes in the underlying processes as quickly as possible. The theory of statistical surveillance provides the possibility of making optimal decisions about whether a change has occurred or not based on the data available at the time of the decision.

  5. 3. Spatiotemporal prediction of arbovirus outbreak risk : the role of weather and population mobility

    Author : Aditya L. Ramadona; Joacim Rocklöv; Yesim Tozan; Hari Kusnanto; Lutfan Lazuardi; Paula Moraga; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; arbovirus; dengue; temperature; rainfall; extreme weather; climate variability; population mobility; twitter data; social media; forecasting model; early warning; epidemic; big data; INLA; spatiotemporal model; climate services;

    Abstract : Background: Arboviruses such as dengue and chikungunya have been a significant public health burden globally for several decades. In Indonesia, all four dengue serotypes are circulating. READ MORE

  6. 4. Evolutionary trajectories of Klebsiella pneumoniae : From experimental biofilm evolution to a hospital outbreak

    Author : Greta Zaborskytė; Linus Sandegren; Vaughn S. Cooper; Uppsala universitet; []
    Keywords : Klebsiella pneumoniae; evolution; experimental evolution; biofilms; infection; bacterial pathogens; Mikrobiologi; Microbiology;

    Abstract : Bacterial evolution is closely intertwined with our lives. As their hosts, we shape how bacteria evolve by imposing numerous selective pressures during the time bacteria spend in our bodies. As a result, they adapt in various ways to colonize us or infect us better. READ MORE

  7. 5. Spatial and temporal dynamics of subarctic birch forest carbon exchange

    Author : Michal Heliasz; Institutionen för naturgeografi och ekosystemvetenskap; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mountain birch; eddy covariance; carbon budget; insect outbreak; forest expansion; temporal variability; spatial variability;

    Abstract : High northern latitudes are of special importance for the global carbon budget as they store large amounts of organic matter in the soil and are expected to be the most strongly affected by climate change. Here we investigate carbon exchange in the subarctic mountain birch forest growing on the limit where tree growth is possible. READ MORE
