New study suggests that raising school ventilation levels to ASHRAE 241 targets could reduce flu cases by 33% for the WHOLE POPULATION! We need clean air in schools so bad!!! www.medrxiv.org/content/10.6...
Climate-Ready Buildings: Insights from U.S. Schools in a Global Context

Climate Week NYC • Sept 23
Projected Health Impacts of Cleaner Air in NYC Schools 
Geetha Jeyapragasan and Charlie Whittaker I University of California, Berkeley
We modelled the projected impact of higher levels of ventilation and filtration in NYC schools. We did this by assessing the impact of achieving a field-recognized standard for healthy indoor air (ASHRAE Standard 241), developed by the American Society for Heating, Refrigeration and Air Conditioning, the professional association of ventilation engineers. Adopting it in schools would reduce the burden of seasonal respiratory illness and improve preparedness for future epidemics.
We developed an epidemiological modelling framework to estimate how improving building air quality affects airborne disease transmission in schools. Here, using seasonal influenza as a case study, we share results about the potential public health impact of raising ventilation such that all schools met ASHRAE 241 targets, approximately 9 equivalent air changes per hour (ACH).
INFLUENZA INFECTIONS AVERTED
PER YEAR
54%
IN CHILDREN
33%
IN OVERALL POPULATION
Share of influenza infections averted in children and the general population if all schools achieved ASHRAE 241 filtration targets. This also results in 30% reduction in hospitalizations across all ages.
IMPACTS

SCHOOL ABSENTEE DAYS
ELIMINATED PER YEAR

PRODUCTIVITY LOSSES
SAVED
Days of school absenteeism prevented each year through reduced influenza transmission, and the value of the parental working time no longer lost to caring for sick children.

Why This Matters for New York City
ALL FLU CASES
New York City operates the largest public school system in the United States, with approximately 880,000 students across 1,800 schools. A large portion of this infrastructure predates modern ventilation standards, with the average school building around 70 years old. An inspection of NYC schools i…

Back-to-school season is here, and so are the school-year germs. Help your child and their classmates have a healthier school year by keeping them home as much as you can when they're sick! If they have to go to school, be sure they have a mask, and encourage them to wear it as much as possible!
Sickness is not a school supply! Things to send to school with your kids: Pencils and pens, A water bottle, Books, Excitement to learn new things!

Things to leave home: COVID-19. The flu, Measles, “Stomach bugs," Any other virus that can spread to others! Help your child recover faster and protect their teachers and classmates by keeping them home as much as possible when they are sick, but if you have to send them to school (we get it, childcare and time off work aren’t 
always easy), send them with a high-quality mask. 

Masks can also protect your child from getting sick with illnesses spread by others!

I hand out respirator/breatheteq masks to my patients to help them reduce their risk of getting COVID and Long COVID. Here's the letter I've put together about this for parents about children masking. @longcovidresource.bsky.social @longcovidadvoc.com @longcovidkids.bsky.social #longcovid
Letter with different typeface colours entitled, "Preventing Long COVID in Children".  Text as follows:

As described by the Public Health Agency of Canada1,
Long COVID (also known as post-COVID-19 condition) affects children as well as adults.
- It’s long-lasting symptoms after a known or unknown COVID infection.  
- The most common Long COVID symptoms in children are:
Fatigue
Headache
Abdominal pain
Sleep problems
Shortness of breath
Cognitive problems (difficulty thinking or concentrating)
Muscle aches and joint pains

I care for children with Long COVID.  It can interfere with their social, physical and educational development.  You do not want your child to develop Long COVID.

While there are some promising therapies, there is no clear cure for Long COVID.

The best way to prevent Long COVID is to prevent COVID infections.
Since COVID is airborne, the best way to prevent COVID infections is to wear respirator-type masks (like N95s) all the time indoors.  This is why I’m giving you this mask for your child to wear.  I personally purchased these to hand out to my patients.  This is how important it is to me, as your child’s doctor, for your child to mask: to protect their health.

I know there will be times at school and other places where your child will want to remove their mask.  Wearing a mask as much as possible in public indoor spaces will greatly reduce your child’s risk of getting COVID, which will reduce their risk of developing Long COVID.  If they wear it 90% of the time, that’s still a huge win and way better than wearing it only 20% of the time, or not at all.

>  Key tip: shape the curve of the nose piece first, then put the mask on.

The choice to ignore COVID was airborne all along meant it spread everywhere and pretty much everyone on Earth has had it at least once, maybe 3 or more times. So 40M+ people died and easily a billion have Long COVID of some degree because women aerosol experts were dismissed by a non-expert man.

New DfE statutory guidance on allergy safety in schools states: "Clean air is a core asthma control measure. Good ventilation, air quality monitoring and supplemental HEPA air filtration are essential." Schools are now legally required to have regard to that. 2/
children. Exercise and cold air can also cause symptoms. Common symptoms include coughing, wheezing and breathlessness out of proportion to effort, and a tight chest. An asthma attack occurs when symptoms are severe, and breathing becomes difficult.

Poor air quality worsens asthma and increases asthma attacks, and those in deprived areas with poorer nutrition suffer increased negative health effects from poor air quality. Clean air is a core asthma control measure. Good ventilation, air quality monitoring and supplemental HEPA air filtration are essential, especially when ventilation is limited and outdoor air is polluted. Systematically integrating and embedding clean indoor air into legal health and safety duties, policies, procedures and practices will reduce pressure on staff and ensure consistency and support without too much extra work.

Children and young people known to have asthma should have their own reliever inhaler at school to treat symptoms and for use in the event of an asthma attack. If they are able to manage their asthma themselves they should keep their inhaler on
