COVID-19: Real impact on children
We were told early in the pandemic that children don't spread the virus, it is mild and later that schools were not centres of transmission. This thread explores some of the real impacts on children. 🧵1/ #LongCovidKids #FASSST #COVID

While surveillance and data collection is being dismantled in many countries, South Korea continued to test at high volumes and were able to see the differences between ages including children ( researchsquare.com/article/rs-172… ). H/T: @DFisman 2/
It turns out, "We found that children are indeed more susceptible to the Omicron variant compared with the previous strains of SARS-CoV-2." 3/
COVID-19: Impact of mask usage and mandates
This thread explores what kind of measured impact mask usage and mandates have actually had in schools and with healthcare workers. TLDR: They substantially reduce infections and outbreaks. #FASSST #LongCovidKids #onted 🧵1/

Healthcare workers are exposing themselves to pathogens every day. Most are just given surgical masks which are not designed to protect against aerosol transmission and have historical reasons for not recognizing this ( onlinelibrary.wiley.com/doi/10.1111/in… ). H/T: @jljcolorado 2/
A new publication looking at 2919 healthcare workers (HCW) with frequent COVID-19 patient exposure found high quality respirators (e.g. N95/FFP2) substantially reduced COVID-19 infections compared to surgical masks ( jamanetwork.com/journals/jaman… ). H/T: @EricTopol 2/
COVID-19: Ottawa and Ontario Back to School Status
Some students go back next week in Ottawa so where are we at with the current BA.5 wave? Wastewater levels stopped going down for the past couple of weeks ( gilchrist.ca/jeff/COVID-19/… ). We need clear air in classrooms #FASSST!🧵1/

Unfortunately they never went back down to low levels. You can see from the graph that after the last few variant waves (Delta, BA.1, BA.2, and now BA.5) that the new baseline level keeps getting higher and higher between waves. 2/
The current wastewater level is almost the same as the peak of the BA.1 wave we had back in January when students still had to wear masks in school but now students are returning to school at similar wastewater levels without any mask requirements. 3/

“The devices do not improve air quality but can be used to gauge whether a room is well or poorly ventilated. Since COVID-19 can spread through the air, they’ve also been used as COVID risk assessment tools.”
“ “If CO2 is increasing in a room, it means you’re not evacuating one of the contaminants accumulating, so that’s probably the case with the others,” explained Stéphane Bilodeau, an indoor ventilation expert and lecturer in the bioengineering department at McGill University.”
COVID-19: Hospital Admissions Better or Worse Now?
In the 3rd summer of the pandemic, are things better or worse? Looking at the # of hospital admissions because of COVID-19 in Ottawa from July 1st to August 15 in 2020, 2021, and 2022 things are definitely worse. 🧵1/

Admissions because of COVID are 18.5x higher this summer than 2021 and 8.4x higher than 2020. Removing all COVID-19 protective measures maybe wasn't the best idea? 2/
Similarly looking at Canada as a whole, hospitalizations are 7.6x higher now than they were this time last year and every day in 2022 has been above the average for 2020-2021 ( ). 3/
COVID-19: Masks mandates reduced Alberta school outbreaks by 68%
In Feb 2022 Alberta was given data that schools are hubs of COVID-19 infections, cases are spread from schools to community and increased risk of children hospitalization each wave ( ). 🧵1/

The very disappointing part is that the Alberta government buried their own analysis and only a court-order was able to bring it to light for the public to see ( ). 2/
They looked at outbreaks in schools with and without mandates and found schools without mask mandates had 3.2x more outbreaks in their schools on average (page 75). 3/
COVID-19: Improving ventilation reduced likelihood of infection by 80% in schools
A preprint study found the relative risk of infection decreased with the increase in ventilation for those equipped with mechanical systems ( arxiv.org/abs/2207.02678 ). H/T: @linseymarr 🧵1/
A preprint study found the relative risk of infection decreased with the increase in ventilation for those equipped with mechanical systems ( arxiv.org/abs/2207.02678 ). H/T: @linseymarr 🧵1/
The study investigated more than 10,000 classrooms in Italy. Ventilation rates ranging from 10-14 L/sec per person reduced the likelihood of infection for students by 80% compared to classrooms with only natural ventilation. 2/
They determined that relative risk was reduced 12%-15% for each additional unit of ventilation rate per person. 3/
COVID-19: Preparing schools to be safer
We are halfway through the summer break and there hasn't been much action to make schools safer in September. 🧵1/

It would be great if our children could have less disruption at school this year since we know what needs to be done, it just needs to get done. 2/
Now that we are on the 7th wave, it should be obvious to policy makers that vaccines alone are not enough so we need to implement additional measures that are known to reduce the risk of infection. 3/
COVID-19: Increase in Canada and World for child hepatitis cases
Looks like child hepatitis cases are continuing to increase in Canada with 24 now (up from 10 in May), all hospitalized and 2 required transplants. 😢 ( ). 🧵1/ #FASSST

The WHO also released a statement recently that as of July 8, 2022 there have been 1,010 probable cases in 35 countries so far including 22 deaths ( globalnews.ca/news/8993497/h… ). 2/
You may remember that adenovirus has been blamed by many for this uptick but so far has only been detected in half of cases in Europe and only 9% of cases in Japan. 3/
“How much of the air you're breathing is air someone else exhaled? And in the midst of a pandemic caused by an airborne virus, where are the riskiest places to be? In the first in a series of five stories Farah Hancock reports on hot spots of hazardous air.”
“Shuffling my way onto the bus I had no idea it might be the most dangerous thing I would do all day…
From a level of 516 parts per million at the bus stop, it took only 20 minutes for CO2 inside the bus to peak at a whopping 5737ppm.”
