Tick-borne diseases are a growing public health concern as their incidence and range have increased in recent decades. Lyme disease is an emerging infectious Canada due to northward expansion of the geographic Ixodes scapularis, principal tick vector for agent Borrelia burgdorferi, into central eastern Canada. In this study geographical distributions Ixodid ticks, including I. environmental factors associated with occurrence were investigated New Brunswick, Canada, where few scapularis...
This study illustrates what may have happened, in terms of coronavirus disease 2019 (COVID-19) infections, hospitalizations and deaths Canada, had public health measures not been used to control the COVID-19 epidemic, restrictions lifted with low levels vaccination, or no Canadian population. The timeline epidemic interventions are reviewed. Comparisons against outcomes other countries counterfactual modelling illustrate relative success Canada. Together, these observations show that without...
Lyme disease is emerging in Canada due to geographic range expansion of the tick vector Ixodes scapularis Say. Recent areas emergence include parts southeastern Canadian Prairie region. We developed a map potential risk for future I. establishment Provinces. Six algorithms were using different formulations three indices environmental suitability: temperature annual cumulative degree-days > 0 °C (DD °C; obtained from Moderate Resolution Imaging Spectroradiometer satellite data as an index...
Australia is currently free of canine rabies. Spatio-ecological knowledge about dingoes in northern a gap that impedes the application disease spread models and our understanding potential transmission rabies, event an incursion. We therefore conducted one-year camera trap survey to monitor dingo population equatorial Australia. The contiguous with remote Indigenous communities containing free-roaming dogs, which potentially interact dingoes. Based on data, we derived density home range size...
This survey aimed to understand hunting practices involving domestic dogs in remote Indigenous communities northern Australia and, the context of disease transmission, describe domestic-wild dog interface and intercommunity interactions during activities.A cross-sectional 13 hunters from Northern Peninsula Area (NPA) Queensland gathered information on demographics dogs, past encounters with wild trips. Social networks that described connections between NPA expeditions were developed.Most...
In Canada, Francisella tularensis , the zoonotic bacterial agent of tularemia, affects mostly snowshoe hares ( Lepus americanus ), muskrats Ondatra zibethicus and beavers Castor canadensis ). Despite numerous studies, ecologic cycle natural reservoirs F. are not clearly defined. We conducted a cross-sectional study to estimate prevalence in hares, muskrats, coyotes Canis latrans ) four regions Québec, describe risk infection relation host environmental characteristics at three spatial...
Estimating rates of disease importation by travellers is a key activity to assess both the risk country from an infectious emerging elsewhere in world and effectiveness border measures. We describe model used estimate number infected with SARS-CoV-2 into Canadian airports 2021, impact pre-departure testing requirements on risk.
The COVID-19 pandemic underlined the need for planning but also brought into focus use of mathematical modelling to support public health decisions. types models needed (compartment, agent-based, importation) are described. Best practices regarding biological realism (including multidisciplinary expert advisors modellers), model complexity, consideration uncertainty and communications decision-makers outlined.
Public health measures applied exclusively within vulnerable populations have been suggested as an alternative to community-wide interventions mitigate SARS-CoV-2 transmission. With the population demography and healthcare capacity of Canada example, a stochastic age-stratified agent-based model was used explore progression COVID-19 epidemic under three intervention scenarios (infection-preventing vaccination, illness-preventing vaccination shielding) in individuals above age thresholds...
Australia, home to the iconic dingo, is currently free from canine rabies. However northern including Indigenous communities with large free-roaming domestic dog populations, at increased risk of rabies incursion nearby Indonesia. We developed a novel agent-based stochastic spatial spread model evaluate potential within dingo population Northern Peninsula Area (NPA) region Australia. The incorporated spatio-temporal features specific this host-environment system, landscape heterogeneity,...
Background: Commercial air travel can result in global dispersal of infectious diseases.During the coronavirus disease 2019 (COVID-19) pandemic, many countries implemented border measures, including restrictions on travel, to reduce importation risk COVID-19.In context inbound Canada, this study aimed to: 1) characterize trends before and during 2) statistically assess association between volumes pandemic.Methods: Monthly commercial volume data from March 2017 February 2023 were obtained...
Free‐roaming domestic dogs in Indigenous communities of northern Australia have the potential to spread diseases at wild–domestic dog interface. Hunting activities with dogs, commonly practiced communities, also create opportunities for interactions bush, providing pathways disease spread. Data from a camera‐trap study conducted remote were used explore spatial and seasonal between dingoes unsupervised dogs. For each type dog, activity indices, based on detection events per camera station an...
In northern Australia, wild dog populations potentially interact with domestic dogs from remote communities, which would create opportunities for disease transmission at the wild–domestic interface. An example is rabies, in event of an incursion into Australia. However, likelihood such interactions ambiguous. Hybridisation analyses based on 23 microsatellite DNA markers were performed canine‐origin scats collected bushland areas around Indigenous communities Northern Peninsula Area,...
