(1/3) One of the biggest challenges of having multiple respiratory viruses circulating at the same time is the large and sudden surge of illnesses that can overwhelm the health system. It also means there is a lot of virus circulating in the community. canada.ca/en/public-heal…
(2/3) This means we may be more likely to encounter viruses as we interact with others in schools, workplaces and social settings, especially indoors and if masks are not being worn.
(3/3) This is why #VaccinesPlus is so important right now. Although no individual layer of protection is perfect, when used consistently & together, layers provide very good protection against #COVID19 & other respiratory infections. #Flu#RSV

(1/5) Today, Canada’s Chief Medical Officers of Health are reinforcing the importance of staying up to date with vaccines to maintain protection against COVID-19 and other vaccine preventable diseases canada.ca/en/public-heal…
(2/5) We are also celebrating the collaboration and efforts of jurisdictions, Indigenous partners, healthcare workers, individuals and communities. Our continued collective efforts will be integral to our emergence from this pandemic.
(3/5) With #COVID19Vaccines now available to anyone 6 months or older, staying up to date means getting a primary series and then #BoosterDoses when you are eligible, recognizing jurisdictions’ programs may differ based on epidemiology and programmatic considerations.
1/5 Today, the COVID-19 Immunity Task Force (CITF) announced seroprevalence results from 21 studies funded by the Government of Canada, estimating the level of infection during the Omicron wave up to the end of May 2022. covid19immunitytaskforce.ca/the-omicron-ts…
2/5 Antibodies to certain blood proteins known as “nucleocapsids” only develop in those who’ve been infected. So detecting their presence in blood (seroprevalence) is a way to estimate the proportion of people with past #SARSCoV2 infection.
3/5 CITF results confirm the massive scale of the #Omicron wave. Before Omicron arrived in Dec 2021, ~7% of Canadians had infection-acquired antibodies to #SARSCoV2. Then from Dec 2021 to May 2022, that proportion rose to 45%!
1/5 The Public Health Agency of Canada is aware that @SickKidsNews has reported cases of acute hepatitis of unknown origin in children to @ONTHealth. This is a relatively rare condition that does occur in Canada. In many cases, an underlying cause cannot be found.
2/5 Information on these and other cases is being further reviewed by health authorities. Those that meet the case definition will be reported to @GovCanHealth to be included in the national investigation.
3/5 We do not know if we are seeing an increase in the number of cases of acute hepatitis of unknown cause in children. More information is needed to assess the situation and any potential risks to people in Canada.
1/5 #COVID19 key concerns 🇨🇦 : as public health measures have eased and we resume more activities and connections, other serious infectious diseases, such as influenza and measles, are making a comeback. canada.ca/en/public-heal…
2/5 #COVID19 is still circulating across the country and Canada is reporting increased #influenza activity in recent weeks, late in the 2021-22 season. This includes the first outbreaks and a sharp rise in influenza detections, mostly in ages <45 years. canada.ca/en/public-heal…
3/5 .@UNICEF & @WHO report a 79% increase in worldwide measles cases in Jan-Feb 2022 compared to the same time last year, a worrying sign of overall heightened risk for spread of vaccine preventable diseases (VPD) that could trigger larger outbreaks. who.int/news/item/27-0…
1/4 #COVID19 key concerns 🇨🇦 : after weeks of increasing transmission, hospitalisation rates are rising in many jurisdictions and across most age groups. Rates of hospital/ICU admission/death remain highest in older adults, aged ≥60 years. health-infobase.canada.ca/covid-19/epide…
2/4 With #COVID19 still spreading widely in Canada, it’s not too late and very important to get the best possible protection against severe illness by keeping #COVID19Vaccines up-to-date, including #COVID19Booster dose(s) as recommended. canada.ca/en/public-heal…
3/4 Evidence shows that 2 doses of mRNA #COVID19Vaccines generally maintain good effectiveness against severe outcomes across variants, and a booster further increases vaccine effectiveness to over 90% against severe outcomes. canada.ca/en/public-heal…
1/7 Today #PHAC released an Update on #COVID19 in Canada: Epidemiology & Preparedness, which underscores the need for ongoing work to prepare for futures challenges as the #SARSCOV2 virus continues to circulate and evolve. canada.ca/content/dam/ph…
2/7 Although Canada’s overall high vaccination coverage and a range of surveillance, public health measures, treatments & other tools can better protect us going forward, we must still prepare for possible resurgence this spring and fall.
3/7 #PHAC is preparing against two key scenarios for the longer-term. A realistic scenario could be one in which we have low-moderate ongoing #SARSCOV2 transmission in Canada, with intermittent waves as new variants emerge or immunity wanes.
