Public Health Ontario (PHO) using different age categories for updated RV tool data
PHO now combines children <1 into a 0-4 age group while before they had separate <1 and 1-4 age categories which makes a big difference in how the impact of children is perceived. 🧵1/
PHO stopped updating COVID-19 hospital admissions and now provide bed occupancy in their recent Respiratory Virus Tool update which uses different age categories ( ). 2/publichealthontario.ca/en/Data-and-An…
You can see from the previous Ontario hospitalization rate by age group that children <1 were hospitalized at 81.8 per 100k population which is more than age 60-79 at 77.2 per 100k population. The 1-4 age group is massively smaller at 7.7 per 100k population. 3/
In the PHO bed occupancy data, you can barely see the 0-4 category compared to the 60-79 age group while infants <1 on their own had higher rates than 60-79. 4/
When combined with kids 1-4 the impact of hospitalization on infants <1 is almost completely lost and parents may not realize how high risk infants are for hospitalization from COVID-19. 5/
When you just look at children, you can see the bed occupancy rate for ages 0-4 are the majority of hospitalization per 100k population for kids < 18, most of which would be coming from the <1 category that is now hidden. 6/

COVID-19 #Wastewater levels in #Ottawa have finally declined significantly but lower does not mean gone as PCR test positivity rates are still at 7.6% ( ). 🧵1/ covid.gilchrist.ca/Ottawa.html
RSV WW levels are 7.7x lower than the peak which was much lower than last year. Influenza had much higher peaks this year than last year and while Flu A levels are low, Flu B hit its peak at the beginning of March and is now declining but still above the peak from last year. 2/

#Variant update for #Ontario, #Canada (to Mar. 14, 2024)
The BA.2.86.* #Pirola clan of variants has made most other lineages extinct in Ontario. The SanKey shows the situation is now much simpler and almost exclusively JN.1 and descendants. Graph tools by @Mike_Honey_ 🧵1/
Right now the JN.1 and JN.1.4 Pirola variant are still the most prevalent. The JN.1.11.1 variant, its descendants (KP.*) and other FLiRT variants will be the ones to watch as they start growing in Ontario and may be able to escape immunity from JN.1 infections. 2/
The % positivity from viral tests is quite a mixture now, the original Coronavirus in lead at 8.2% with COVID-19 in 2nd (6.3%) then Entero/Rhinovirus (5%), Human metapneumovirus (4.6%), Influenza A (4%), Influenza B (3.8%), Parainfluenza (3.4%) ( ). 3/ publichealthontario.ca/en/Data-and-An…
A nine year old boy named Matt in Singapore was infected with COVID in January 2024. Unfortunately he developed myocarditis (inflammation of the heart muscle) from the COVID infection and then had a stroke which weakened his left side ( ). 🧵1/ straitstimes.com/life/triple-wh…
After being admitted to hospital, his heart failed and he was required to be put on the most invasive form of life support extracorporeal membrane oxygenation (ECMO), which temporarily does the job of the heart and lungs. H/T: @MeetJess 2/
His initial stay in the hospital was 5 weeks before he was discharged on Feb. 8, 2024 to recover but then was readmitted again twice for other virus infections on Feb. 11, 2024 for 3 days and then on Feb. 22, 2024 for another infection. 3/
As Public Health crumbles and too few people are getting vaccinated for measles our herd immunity levels have dropped too much and now many people are at risk for a disease we almost eradicated in Canada. 🧵1/

There has been a huge surge in measles cases around the world including cases in the UK and USA. The government is strongly advising everyone in Canada to be vaccinated with 2 doses of measles vaccine, especially before travelling ( ). 3/canada.ca/en/public-heal…
#Variant update for #Ontario, #Canada (to Feb. 21, 2024)
You can see how much the BA.2.86.* #Pirola clan of variants has made a clean sweep since January. The left SanKey shows the variant soup from December while the right is now much simpler. Graph tools by @Mike_Honey_ 🧵1/
The Pirola clan still makes up more than 90% of sequences in Ontario but may have reached its peak for now. The JN.1 variant dropped from 50% down to 38% while its child JN.1.4 is gaining ground above 25%. 2/

After I wrote about PM from ultrasonic humidifiers, people asked how much PM does a hot shower produce? TLDR: Much less for a quick shower, around 12 ug/m^3 compared to 800 ug/m^3 for the ultrasonic. 🧵1/
But not all PM is equal so look later in the thread for different types of PM that are more dangerous. 2/
The PM monitor was placed on the sink counter beside the shower. Our shower is mostly enclosed with a door but has a 28cm (11 inch) gap at the top to let air in/out. 3/
