There is increasing evidence for a latitudinal and altitudinal shift in the distribution range of Ixodes ricinus. The reported incidence tick-borne disease humans on rise many European countries has raised political concern attracted media attention. It disputed which factors are responsible these trends, though ascribe shifts to climate changes. Any possible effect would be most easily noticeable close tick's geographical limits. In Norway- being northern limit this species Europe- no...
Global environmental change is causing spatial and temporal shifts in the distribution of species associated diseases humans, domesticated animals wildlife. In on-going debate on influence climate vectors vector-borne diseases, there a lack comprehensive interdisciplinary multi-factorial approach utilizing high quality data. We explored biotic abiotic factors with latitudinal altitudinal Ixodes ricinus observed during last three decades Norway using antibodies against Anaplasma...
Tick-borne encephalitis (TBE) is among the most important vector borne diseases of humans in Europe and currently identified as a major health problem many countries. TBE endemic zones have expanded over past two decades, well number reported cases within areas. Multiple factors are ascribed for increased incidence TBE, including climatic change. The has also Norway decade, human cluster along southern coast Norway. In distribution prevalence virus (TBEV) tick populations largely unknown....
Collaboration across sectors, disciplines and countries is a key concept to achieve the overarching One Health (OH) objective for better human, animal environmental health. Differences in terminology interpretation of terms are still significant hurdle cross-sectoral information exchange collaboration within area OH including Surveillance (OHS). The development here described glossary collaborative effort three projects funded European Joint Programme (OHEJP). We describe infrastructure...
Tick-borne encephalitis (TBE) is a viral disease endemic in Eurasia. The virus mainly transmitted to humans via ticks and occasionally the consumption of unpasteurized milk products. European Centre for Disease Prevention Control reported an increase TBE incidence over past years Europe as well emergence new areas. To better understand this phenomenon, we investigated drivers through expert knowledge elicitation. We listed 59 possible grouped eight domains elicited forty experts to: (i)...
Climate change has had a major impact on seasonal weather patterns, resulting in marked phenological changes wide range of taxa. However, empirical studies how seasonality the emergence and dynamics vector-borne diseases have been limited. Lyme borreliosis, bacterial infection spread by hard-bodied ticks, is most common disease northern hemisphere rapidly increasing both incidence geographical distribution many regions Europe North America. By analysis long-term surveillance data (1995–2019)...
The factors that drive the emergence of vector-borne diseases are difficult to identify due complexity pathogen-vector-host triad. We used a novel comparative approach analyse four long-term datasets (1995-2015) on incidence tick-borne in humans and livestock (Lyme disease, anaplasmosis babesiosis) over geographic area covered whole Norway. This allowed us separate general (shared vector) specific (pathogen reservoir host) limiting diseases, as well role exposure non-shared pathogens...
In response to the coronavirus disease (COVID-19) pandemic, most countries implemented school closures. Norway, schools closed on 13 March 2020. The evidence of effect transmission was limited, while negative consequences were evident. Before reopening, risk-assessment for paediatric risk groups performed, concluding that children can attend with few conditions requiring preventative homeschooling. We here present infection prevention and control guidelines primary recommendations groups.
Farm animals have been identified as an emerging reservoir for transmission of livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) to humans. The low incidence MRSA in humans and farm Norway has led the implementation a national strategy surveillance control LA-MRSA aiming prevent livestock becoming domestic source In 2015, clonal complex 1 spa-type t177 was nine Norwegian pig herds two neighboring counties. An outbreak investigation undertaken, measures through...
In Scandinavia, the distribution of ticks is expanding and tick-borne diseases constitute growing health risks. While probability getting a disease after tick bite low, impacts can be large. This, as well other characteristics these make tick-related risks difficult for laypeople to assess perceived risk may differ substantially from actual risk. Understanding perceptions important since it risk, rather than that determine behaviour even more so new emerging The aim this study investigate...
Emergence of tick-borne diseases is impacting humans and livestock across the Northern Hemisphere. There are, however, large regional variations in number cases diseases. Some areas have surprisingly few disease compared to other regions. The aim here provide a first step towards better understanding such contrasting patterns emergences at northern distribution range Ixodes ricinus Europe. We compare incidence, vector abundance pathogen prevalence eastern western Norway differing cases....
Tick-borne infections are of emerging and increasing concern in the Scandinavian countries Denmark, Norway Sweden. Only few studies have investigated protective practices against tick bites general population. The aim this multi-country study was to assess use perception efficacy them.We surveyed extent using bites, same questionnaire three local languages. In addition, we perceptions how good a protection different provide. Altogether 783 individuals from 789 1096 Sweden participated by...
Tick-borne diseases are emerging and re-emerging threats causing public health concerns in Europe North America. Prevention control requires understanding of human exposure behaviour. The aim was to measure tick bites across Scandinavia, its spatial distribution the associated risk factors.MethodsWe sent a web-based survey randomly chosen population analysed answers by Principal Component Analysis Chi-Square. Individual responses were aggregated at municipality level assess...
Abstract Lyme borreliosis, the most common vector‐borne disease in Europe and North America, is attracting growing concern due to its expanding geographic range. The growth incidence spread largely attributed climate land‐use changes that support tick vector thereby increase risk. Despite a wide range of symptoms displayed by borreliosis patients, demographic patterns clinical manifestations seasonal case timing have not been thoroughly investigated may result from differences exposure,...
Abstract Background Closed fitness centers during the Covid-19 pandemic may negatively impact health and wellbeing. We assessed whether training at increases risk of SARS-CoV-2 virus infection. Methods In a two-group parallel randomized controlled trial, center members aged 18 to 64 without Covid-19-relevant comorbidities, were access or no-access. Fitness applied physical distancing (1 m for floor exercise, 2 high-intensity classes) enhanced hand surface hygiene. Primary outcomes RNA status...
Many vector-borne diseases are transmitted through complex pathogen-vector-host networks, which makes it challenging to identify the role of specific host groups in disease emergence. Lyme borreliosis humans is now most common zoonosis Northern Hemisphere. The caused by multiple genospecies Borrelia burgdorferi sensu lato bacteria ixodid (hard) ticks, and major transmit with different pathogenicity, causing variable clinical symptoms humans. health impact a given group function number ticks...
There is growing awareness and recognition of the importance One Health paradigm to address existing environmental threats recognise emerging ones at an early stage among Arctic residents, public health agencies, wildlife resource managers. The approach, emphasising interconnectedness human, animal, ecosystem health, plays a pivotal role in addressing these multifaceted issues. Warming climate permafrost thaw may influence both contaminant exposure spread zoonotic infectious diseases have...
During the pandemic outdoor activities were encouraged to mitigate transmission risk while providing safe spaces for social interactions. Human behaviour, which may favour or disfavour, contact rates between questing ticks and humans, is a key factor impacting tick-borne encephalitis (TBE) incidence. We analyzed annual weekly TBE cases in Finland, Norway Sweden from 2010 2021 assess trend, seasonality, discuss changes human tick exposure imposed by COVID-19. compared pre-pandemic incidence...
