The number of young people and toddlers with respiratory illnesses is lately outpacing the ability of our fitness formula to care for them. More Canadian adults will die from COVID-19 this year than last year or in 2020.
Eight percent of people vaccinated with COVID infections that do not require hospitalization end up with prolonged COVID, with each subsequent infection repeating the risk. COVID increases the risk of cardiovascular and other problems, enough to cause a sharp build-up in over deaths and shorten life expectancy.
In 2020, when adult intensive care teams were at risk of being overwhelmed, we wore masks and accepted restrictions. Now that pediatric intensive care is threatened, will leaders stick to the evidence and tell us to hide?While federal officials and several provinces now put Face Mask in all indoor public spaces: Ontario’s top health medical officer, Kieran Moore, was spotted without a mask at a party. There is still no return to arrest warrants for the public.
Use the available mask
It is now known that the mask saves you from the spread of respiratory diseases; some older than others.
The maximum effective masks, and those identified as respiration coverage through formal standards, are respirator masks: N95, CaN99, FFP3 and reusable elastomer respirators. .
Even without compatibility testing, respirators prevent more than 90% of waste smaller than one micron (submicron waste, the smallest of which is considered relevant) from reaching the user.
Ventilators are expensive, typically a few dollars each, but thanks to Canadian manufacturers, they are available and there are no more supply chain concerns for frontline workers. They can be safely reused, with intelligent retention of their filtration. The new models are comfortable and have faces of maximum compatibility.
The N95s are constant with aerial fasteners, offering a smart seal on the edges. KN95 and KF94 have just the right filtration material, but their earrings do not provide such a seal and their filtration is approximately 70%. A qualified medical mask with a cloth mask that fits snugly into it, preferably with air fasteners, provides similar filtration at a lower cost.
Level 1 rated medical masks alone do not have good compatibility, which affects their filtration ability, as unfiltered air passes through the edges with each breath. cloth mask, preferably with aerial fasteners; Both are around 50 percent.
The ill-fitting cloth mask and the non-certified procedure mask are worse than 50%, but bigger than nothing. The World Health Organization advises: “Make the use of a mask a general component of the presence of other people”, to which we would add: use the largest amount of productive mask available.
Previous filtration knowledge is reflected through epidemiological knowledge that it appears that coverage correlates with mask type. An exception and they deserve not to be used to save you from the spread of respiratory diseases.
Masks against COVID-19 and other respiratory infections. They are also an ideal tool for countering COVID variants, as well as RSV and influenza. They work on fundamental physical principles – impaction, sedimentation and diffusion – regardless of the variant or strain.
Staying home when you are in poor health is helpful, but many other people are contagious before they have symptoms, or never have them. Wearing a mask to prevent inflamed waste from reaching the environment is a fundamental pollution control: the most effective is at the source.
The use of masks to protect the person, once controversial, is now regulated by filtration science and epidemiology. The effect of mask mandates in countries where spontaneous masking was low has been continuously demonstrated, demonstrating that mask protection is all of us.
Why don’t other people wear masks?
Why don’t other people wear masks? Some do not forget the inconsistency of the recommendations at the beginning of the pandemic. Masks can be with closures and capacity restrictions and the consequent difficulties. Whatever the reason (stigma, peer pressure, or fear of signage of distinctive features), countries outside of Asia do not have a culture of wearing masks.
In those circumstances, more than strict recommendations are likely to be needed to achieve the maximum rate of mask use that is as effective as possible in reducing respiratory virus transmission. It masks people, imperfectly. Mandatory use of masks (or strong voluntary use of masks) populations.
Reviving mask mandates with an unequivocal signal from governments about the effectiveness of mask and mask mandates would be the most productive quick reaction to our current crisis. Confidence in the efficacy of wearing a mask is geographically correlated with willingness to wear a mask: over time, we hope that wisdom will replace culture. Strong communication from political and public health leaders would allow the network to better perceive that the small inconvenience of wearing a mask in indoor public spaces is justified by having prevented death and disability. .
In North America, the strategy of wearing masks based on non-public judgments failed predictably, the strategy of emphatically recommending masks has not been tested and is too old due to experiments. However, mask mandates are backed by solid evidence of effectiveness. in Canada and the United States.
Mask mandates are less harmful to a recovering economy than physical distancing and capacity limits, and less harmful to learning than going back to distance learning.
Schools and universities are a vital opportunity. COVID spreads among young people in schools to infect the entire population; This is mitigated by wearing a mask. After Massachusetts lifted its mask mandate, school forums did so at other times, creating an herbal experience: superior transmission among scholars and staff where mandates were lifted compared to those still in place.
There is no convincing evidence to date that masks the decline in social or language skills. Reducing spread in schools would increase learning by reducing days of ill health for students and teachers and preserving in-person instruction. Keeping young people in school helps keep parents working.
Mask mandates will not produce a quick fix to our existing disorders with respiratory viruses. The indicators will be weeks behind. Until we have a technique for all of society that recognizes that COVID is airborne, mask mandates should give us the best quick chance to maintain our healthcare system, mitigate deaths and disabilities from breathing viruses, the economy, and maintain social contact safely. our personal lives.
