    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 been diagnosed with ASD.
    • The prevalence of ASD varies considerably from one region to another, varying from 0.7% to 1.8% among persons aged 4 to 17 years.
    • The lifetime prevalence...

    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 deaths, the third leading cause of premature mortality and the fourth most significant health burden.
    • Cognitive impairments have significant economic and health impacts for informal caregivers...

    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, Mauricie et Centre-du-Québec, Outaouais and Montérégie.
