";s:4:"text";s:6439:"Because many HVAC systems move air and some infectious diseases travel by air, there is interest in whether HVAC systems can play a role in managing infectious disease transmission. I hope this article is picked up by Public Health Officials.
As there is no formal scientific definition of SSE at play, nor any World Health Organization-established protocol for cataloguing them, I simply spent several weeks scanning the scientific and lay press for any information I could find, using search terms such as “superspreader,” “cluster,” “hot spot”; or non-English variants, such as I am not an epidemiologist, let alone a virologist. Given that the contagious period appears to run into weeks this is a very small number. Observe the following cautions when considering ionization treatment: (1) There are no industry standards or test protocols for bipolar ionization systems, so performance is not verified. But outdoor social contact is much safer than its indoor equivalent, because, other factors being equal, the same infected droplets that would otherwise concentrate in unventilated indoor spaces are whisked away by even slight breezes. We erred on the side of caution, and understandably so. Every nation is reporting its data in a different way. by Jonathan Kay. Reducing the dose reduces the kill rate. Some experts estimate that inhaling 1,000 infectious virus particles is enough for the COVID-19 virus to take hold. Despite the passage of four months since the first known human cases of COVID-19, our public-health officials remain committed to policies that reflect no clear understanding as to whether it is one-off ballistic droplet payloads or clouds of fine aerosols that pose the greatest risk—or even how these two modes compare to the possibility of indirect infection through contaminated surfaces (known as “fomites”).Gaining such an understanding is absolutely critical to the task of tailoring emerging public-health measures and workplace policies, because the process of policy optimization depends entirely on which mechanism (if any) is dominant:Unfortunately, the available international data hasn’t been particularly helpful in addressing this inquiry.

Canadian journalist Jonathan Kay analyzed 58 separate COVID-19 "super spreader" events in 28 countries. You hear the term “shedding virus” but it is not obvious how and when this shedding happens. Table 1 analyzes airborne spread of aerosols, so could overstate the viral load to the extent viral particles are in large droplets that do not travel with air currents. Bipolar ionization breaks air into positive and negative ions. Here in Canada, the Liberals made a naked grab for unchecked fiscal powers that would have lasted till the end of 2021. (Advance to the 8:30 mark of When do COVID-19 SSEs happen? Each system needs an engineering evaluation, but take a 25-ton rooftop heating and air conditioning unit that serves 10,000 sq. And the data I am working with is substandard anyway, as there are all sorts of obvious selection biases at play, including the editorial biases of the journalists on whom I rely for local reports. But his discoveries saved countless lives.
