Portrait of zoonoses prioritized by Quebec’s observatory on zoonoses and climate change adaptation in 2015

  • In Québec, like elsewhere in the world, diseases that can be transmitted from animals to humans (zoonoses), which account for about 60% of diseases communicable to humans, are currently emerging. The complex dynamics of zoonoses can be affected by climate change. In response to this complexity, the Observatoire initiated a zoonosis prioritization approach in 2015 in the context of climate change. This approach allowed it to develop a portrait of zoonoses that will serve as the basis for documenting their evolving situations in Québec, in an effort to anticipate potential issues of concern. Documenting the zoonoses also allowed it to better identify the challenges and knowledge gaps specific to the prioritized zoonoses, thereby serving as a tool to direct and optimize zoonosis research, surveillance, prevention and control activities. Twelve zoonoses were prioritized: food-borne botulism in Nunavik, campylobacteriosis, cryptosporidiosis, eastern equine encephalitis, verotoxige…

Report on Surveillance of the West Nile Virus and Other Arboviruses in Québec: 2016 Season

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 were tested for WNV, 101 for EEEV, and 91 for CSGV. Among them, 28 (3%), 4 (4%) and 2 (2%), respectively, tested positive for these viruses. No Aedes albopictus mosqui…

Report on Surveillance for Lyme Disease: 2016

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.

Methicillin-Resistant Staphylococcus aureus Bloodstream Infections Surveillance results: 2016-2017

Methicillin-Resistant Staphylococcus aureus Bloodstream Infections
Surveillance results: 2016-2017

From April 1st, 2016 to March 31st, 2017, 89 healthcare facilities participated in the surveillance of methicillin-resistant Staphylococcus aureus (MRSA) bloodstream infections, for a combined total of 4,835,605 patient days (Table 1). Together, these facilities reported 66 cases of healthcare-associated MRSA bloodstream infections (HA-MRSA-BSI) acquired during a current or previous hospitalization (categories 1a and 1b). The HA-MRSA-BSI incidence rate was 0.14 per 10,000 patient days. While this incidence rate has been declining for the past five years, this year was comparable to the last one. The proportion of methicillin resistance in healthcare-associated S. aur…

The acquisition rate of HA-VRE colonization (cat. 1a and 1b) in 2016-2017 was 7.43 per 10,000 patient days and was lower compared to 2015-2016. For all results, analyses include facilities that participated for a minimum of 11 periods. Data were extracted on June 1s…

Surveillance results: 2016-2017

From April 1st, 2016, to March 31st, 2017, 82 healthcare facilities took part in the surveillance of carbapenemase-producing Gram negative bacilli (CPGNB) infections, for a total of 4,448,999 patient days (Table 1). These facilities reported 17 healthcare-associated CPGNB (HA-CPGNB) infections among patients who acquired their strain during a current or previous hospitalization (categories 1a and 1b). The incidence rate of HA-CPGNB infection was 0.04 per 10,000 patient days. The acquisition rate of HA-CPGNB colonization was 0.57 per 10,000 patient days. Eight infections were observed among healthcare facilities that joined the surveillance this year. Two teaching and one non-teaching facilities discontinued their participation this y…
