    This report discusses the prevalence and the incidence rate of autism spectrum disorder (ASD). It also demonstrates the capability of the Québec Integrated Chronic Disease Surveillance System (QICDSS) to identify the comorbidities associated with ASD and the profile of health services utilization. These estimates were obtained from a longitudinal study covering the period from April 1, 2000, to March 31, 2015, for all persons eligible for health coverage between the ages of 1 and 24 years. To be considered to have ASD, the individual must have had at least one medical visit or hospitalization with a principal diagnosis of ASD.

    • The results show a constant growth in ASD over time. In 2014-2015, there were nearly 17 000 persons in Québec between the ages of 1 and 17 who have...

    Population aging is occurring particularly rapidly in Québec. Moreover, cognitive impairments increase with advancing age and become a more significant source of disability as seniors age. Cognitive impairments adversely affect the exercise of such mental functions as memory, judgment, attention, learning capacity and the ability to solve problems, and such impairment can have a significant impact on the ability to remain autonomous and on quality of life. The main types of cognitive impairment are: age-related cognitive decline, mild cognitive impairment and major neurocognitive Alzheimer’s-type dementia for which there is still no cure.

    • In Canada in 2015, Alzheimer’s disease and related dementias were the second leading cause of mortality, responsible for 12% of...

    In 2016, 174 cases of Lyme disease were reported to public health authorities, including 124 cases that were acquired in Québec.

    The Laboratoire de santé publique du Québec received 2 158 Ixodes scapularis ticks from Québec, primarily from the regions of Estrie, Mauricie et Centre-du-Québec, Montréal, Laurentides, Lanaudière, Montérégie and the Capitale-Nationale. More than 17% of these ticks were positive for Borrelia burgdorferi.

    Active surveillance carried out in 2016 made it possible to collect 1 036 Ixodes scapularis ticks of which 82 were positive for Borrelia burgdorferi: they were spread over 22 sites mostly located in Montérégie. Active surveillance identified four new endemic municipalities for Lyme disease in Estrie,...

    In 2016, the Ministère de la Santé et des Services sociaux (MSSS) asked the Institut national de santé publique du Québec (INSPQ) to add the eastern equine encephalitis virus (EEEV) and the California serogroup viruses (CSGV) to the West Nile virus (WNV) integrated surveillance. The MSSS also requested surveillance of the Aedes albopictus mosquito.

    During 2016, 30 cases of WNV infection and five cases of encephalitis linked to CSGV were reported to the public health service. All of the cases were acquired in Québec.

    Therefore, 53 entomological stations were set up in the province of Québec: three specifically to collect EEEV vectors, nine for Aedes albopictus surveillance, and 41 for combined WNV and CSGV surveillance. In all, 935 mosquito pools...

    Second of a two-part series, this document presents the results of an ethnographic research project entitled Préoccupations, opinions, apprentissages et souhaits quant aux risques et à la gestion des risques de la population de la région de Lac-Mégantic [Concerns, opinions, lessons learned, and wishes respecting risk and risk management among the population of the Lac-Mégantic region]. This qualitative study was commissioned by the Direction de santé publique de l’Estrie after the Lac-Mégantic rail disaster of July 6, 2013. Between July 2014 and February 2015, 57 semi-structured interviews were conducted with evacuated and non-evacuated residents of Lac-Mégantic, residents of other area municipalities, and socioeconomic stakeholders. The study makes no claim to represent the...

    • Environmental noise, defined as noise emitted from all sources excluding those in the workplace, is pervasive and constitutes a risk to health and quality of life.

    • The review of the scientific literature shows that noise is a public health issue that can have multiple consequences, both physical and psychosocial. Environmental noise can be a source of sleep disturbance, interference with the ability to learn at school, cardiovascular disease, annoyance (discomfort, disturbance), hearing loss and tinnitus.

    • Environmental noise is a source of complaints and lawsuits, which are indicative of social acceptance issues. Public reactions attest to diverging interests in society, particularly with regard to the model and overall vision of land...

    Since 2002, the number of road traffic deaths in Québec has been falling steadily, even though the number of motor vehicles on the road – automobiles, in particular – has increased considerably. Nevertheless, the use of alcohol, drugs and medications is frequently cited as a cause of road traffic accidents by public authorities, since these psychoactive substances have the potential to impair driving.

    The aim of this study is to present a profile of the psychoactive substances (i.e. alcohol, drugs and medications) examined and detected among motor vehicle and motorcycle drivers aged 16 years and over who were killed in road traffic accidents in Québec from 2002 to 2013.

    The main findings are as follows:

    • The presence of psychoactive substances in the...

    This collection of fact sheets, which was prepared in response to numerous requests for simple and accurate information on psychosocial risk (PSR) factors in the workplace, is intended to serve as a practical tool for occupational health workers as a whole. The fact sheets were drawn up by experts from the Équipe de prévention des risques psychosociaux du travail et promotion de la santé des travailleurs (Team for the prevention of psychosocial risk factors in the workplace and the promotion of workers’ health) of the Institut national de santé publique du Québec (INSPQ), in collaboration with the Groupe scientifique sur l’impact des conditions et de l’organisation du travail sur la santé (Scientific panel on the impact of working conditions and work organization on health), made up of...

    Given the desire to harmonize medical and nursing practices in the field of sexually transmitted infections (STIs) and the need to provide better guidance on the intervention known as expedited partner therapy (EPT), the Institut national de santé publique du Québec received a request from the Collège des médecins du Québec and the Ministère de la Santé et des Services sociaux. The purpose of this request was to issue a scientific opinion, including recommendations, on the effectiveness, benefits and drawbacks of the EPT strategy for Chlamydia trachomatis (Ct) and Neisseria gonorrhoeae (Ng) infections, the best practice to endorse as well as the conditions required to promote its appropriate use.

    In Québec, two STI preventive interventions targeted for...

    The Identification guide for ticks found in Québec was developed for physicians, veterinarians and other health professionals to inform them about the main types of ticks found in Québec and to help them identify specimens brought to them by their patients.

    There are about 900 tick species worldwide. Ticks are Acari that parasitize most vertebrates, including humans, by feeding on their blood.

    In Québec, 12 tick species have been identified so far. Some tick species are reservoirs and vectors of viruses, bacteria and parasites: they are the second leading vector of human disease, after the mosquito. The black-legged tick (Ixodes scapularis) is the tick that transmits the bacterium Borrelia burgdorferi, the agent...
