Researchers from the Technical University of Munich in Germany and the University of Helsinki in Finland led a study that discovered a receptor called neuropilin-1 gives the novel coronavirus a leg-up in infecting our tissues. https://www.sciencealert.com/a-second-key-used-by-sars-cov-2-to-enter-cells-could-explain-why-it-s-so-infectious.
Why is it more infectious to men? Antibodies and Interferons with the X-Chromosome?
People who were infected actually need to keep future infections of all kinds to a minimum. This appears to be the long Covid problem. See also opportunistic pathogens/infections.

Please use the ATP test over uncontrolled UV tests for measuring the hygienic quality of a surface. Click to – “How does one measure the hygienic quality or cleanliness of a surface or object. What does clean mean”.
UV light can be used for a multitude of purposes. The less intense (lower frequency UV can be used as a diagnostic tool). More intense energy UV radiation (high frequency UV) can be used to alter bacteria. The three main types of UV rays are UVA, UVB, and UVC. Because UVC rays have the shortest wavelength, and therefore highest energy, they are capable of killing bacteria and viruses, also called pathogens. UVC light has a wavelength of between 200 and 400 nanometers (nm). It is highly effective at decontamination because it destroys the molecular bonds that hold together the DNA of viruses and bacteria, including “superbugs,” which have developed a stronger resistance to antibiotics. But UVC can quickly impact and effect human skin and other tissues.
Many natural substances do glow under UV: semen, urine, mineral oil, earwax, perspiration. Pest control companies use UV light to detect rat feces and urine which also fluoresce under UV. Some bugs can be detected. Cells can be stained (decorated) with salts or reagents like tetrazolium chloride (CTC) and salts.

For UV fluorescence radiation must be absorbed at a certain wavelength and reemitted at another (visible wavelength). A recent study swabbed a number of surfaces in critical healthcare situations and looked at levels of bacterial contamination of surfaces that fluoresced under UV versus those that didn’t https://rectofossal.com/bacteria-glow-dark/. “.. colony densities were significantly higher in non-fluorescing areas versus fluorescing areas! It was also found that the color of fluorescence may determine the level of sanitation necessary to properly clean a room. Therefore one cannot argue the fact that surfaces that do not fluoresce under UV are clean or free of bacterial contamination i.e. lack of fluorescence is not indicative of the absence of bacterial contamination.” Fluorescence is diagnostic technique – bacteria can also be stained or genetically engineered so they will fluoresce. Fluorescent biomolecules such as flavins and the amino acid tryptophan do exhibit fluorescence. These are often present in bacteria and other living cells but fluorescence is very specific: a particular molecule will absorb at a particular wavelength and re-emit at another, specific wavelength – molecules like tryptophan if buried in a cell or its membrane might not show adequate fluorescence to be noticed at least without sensitive sensors.
Riboflavin (Vitamin B2) reliably emits at a bright green 560nm when exposed to a broad spectrum of UV and bacteria are rather partial to flavins – as are we all: they are essential for metabolism. This is the molecule most UV systems easily detect.

Bayzi Corporation supports GA (general Aviation) aircraft users. If you think that the steam sanitation could work for you please contact us at Bayzi Corporation. We will be happy to arrange for a free one time Top-Off Sanitation for up to three GA small aircraft, per airport within 50 miles of our manufacturing plant (Cincinnati, OH), for all those who request it during September 2020.
This service is recommended by the GA pilot employees of Bayzi Corporation (Cincinnati USA).
Prior to making the request please familiarize yourselves with the information on Bayzi.com. The contact request is made here.*
Bayzi Corporation will provide a price reduction coupon to GA aircraft owners outside and in the Cincinnati area for the purchase of SaniZap® Units.
* The free top-off will be made only to non electrical, non avionics, non critical parts like the seats and carpets. Can be performed only under the supervision of the aircraft owner.
This is commonly measured by an ATP (Adenosine Triphosphate) test-meter that measures RLU’s (Relative Light Units) from swabbed regions. The number and types of bacteria present on a surface is of concern for infection control, but bacterial tests are sometimes very specific and do not yield the overall hygienic condition or cleanliness of a surface. RLU measurements on the other hand are more appropriate to define general cleanliness. ATP is a molecule found in and around living cells, and as such it gives a direct measure of biological concentration and health. ATP (adenosine triphosphate) is a molecule made up of an adenine ring, a ribose sugar, and most importantly 3 phosphates. In the most basic terms, this molecule is the body’s currency for all of its functions. Anything that the body does requires energy which all comes from ATP.The fats, carbs, and proteins that we eat are broken down and metabolized in order to replenish the used ATP in our bodies. One of the phosphates breaks off and releases a burst of energy. When this happens the molecule turns into ADP (adenosine diphosphate) because there is only 2 phosphates attached. Through a series of reactions another phosphate is attached and the molecule becomes ATP again. The ATP in our bodies are recycled after they produce energy.
ATP is quantified by measuring the light produced through its reaction with the naturally occurring enzyme luciferase using a luminometer. The amount of light produced is directly proportional to the amount of ATP present in a sample.

This issue comes up often when comparing cleaning techniques. For example when comparing chemical use and duration to rapid clean steam.
Bleach often contains Sodium Hypochlorite — Sodium hypochlorite can cause severe eye irritation and if ingested can cause severe stomach irritation and sores. Sodium Hydroxide is also often used to stabilize household bleach. It is extremely caustic and can cause significant skin irritation if touched.
Other simple cleaners contains trace doses of 2-butoxyethanol — sustained inhalation of high concentrations (100-500 ppm) of this compound has been found to cause adrenal tumors in tested animals. Please consult toxicologists for a definitive analysis.
An non-intuitive feature of using chemicals over steam is noted in the energy usage. See for example (click).
