From John's Hopkins Hospital regarding the Covid-19 virus…

 

This virus is not a living organism. It is a protein molecule (RNA or DNA) covered by a protective layer of lipid (fat), which, when absorbed by the cells of the ocular (eyes), nasal (nose) or buccal mucosa (mouth), changes their genetic code (mutates) and converts into aggressor and multiplier cells. 

Since the virus is not a living organism, but is a protein molecule, it cannot be killed. It has to decay on its own. The disintegration time depends on the temperature, humidity and type of material where it lies 

The virus is very fragile; the only thing that protects it is a thin outer layer of fat, and that is the reason why soap or detergent is the best weapon.  The foam CUTS THE FAT (that is why you have to scrub for 20 seconds or more, to create lots of foam).  By dissolving the fat layer, the protein molecule disperses and breaks down. 

 

HEAT melts fat; this is why it is necessary to use water above 77 degrees for washing laundry and cleaning surfaces. In addition, hot water makes more foam, making it more effective. 

 

Alcohol or any mixture with alcohol over 65% DISSOLVES ALL FAT, especially the external lipid layer of the virus. 

 

Any solution with 1-part bleach and 5 parts water directly dissolves the protein, breaking it down from the inside. 

 

Oxygenated water increases the effectiveness of soap, alcohol and chlorine, because peroxide dissolves the virus protein. However, because you have to use it in its pure form, it can damage your skin. 

 

NO BACTERICIDE OR ANTIBIOTIC WILL WORK because the virus is not a living organism like bacteria; antibodies cannot kill what is not alive. 

 

The virus molecules remain very stable at colder temperatures, including air conditioning in houses and cars.  They also need moisture and darkness to stay stable. Therefore, dehumidified, dry, warm and bright environments will degrade the virus faster. 

 

UV LIGHT on any object that may contain the virus breaks down the protein.  Be careful, it also breaks down collagen (which is protein) in the skin. 

 

The virus CANNOT go through healthy skin. 

 

Vinegar is NOT useful because it does not break down the protective layer of fat. 

 

NO SPIRITS, NOR VODKA, serve. The strongest vodka is only 40% alcohol, and you need a minimum of 65%. 

 

LISTERINE is 65% alcohol. 

 

The more confined the space, the higher the concentration of the virus there can be. The more open or naturally ventilated, the less. 

 

You have to wash your hands before and after touching any commonly used surfaces such as: mucosa (mouth area), food, locks, knobs, switches, remotes, cell phones, watches, computers, desks etc…and don’t forget when you use the bathroom. 

 

You have to MOISTURIZE YOUR HANDS due to frequent washing.  Dry hands have cracks and the molecules can hide in the micro cracks the thicker the moisturizer, the better.

Also keep your NAILS SHORT so that the virus does not hide there.

Hypochlorous Acid: harnessing nature's germ killer

By Margie Recalde, OD, FAAO December 20, 2019

 

Hypochlorous acid (HOCl) is the perfect weapon to fight germs. It hits hard against pathogens like Methicillin-Resistant Staphylococcus Aureus and Pseudomonas Aeroginosa. Yet this powerful weapon is 100 percent safe for humans, chemical free, non-toxic and all-natural. That’s an impressive combination. It has been used in the medical field for over a century. Before antibiotics were available, HOCl was used to irrigate and disinfect wounds in World War I.  It is now used in everyday settings including daycare centers, hospitals, and even produce sections in grocery stores.HOCl is a weak acid that occurs naturally in our body. Neutrophils are white blood cells that are the first to arrive on site when an invading pathogen is detected. Neutrophils will chase down and engulf the pathogen through phagocytosis. Upon contact, neutrophils release a burst of bactericidal chemicals including its most powerful oxidizing agent, HOCl. This kills the pathogen by tearing down the cell membranes and proteins. 

 

Killing germs

As you are aware, we have other strong disinfectant agents at our disposal. Bleach is widely used in hospitals and medical practices and shares the same chlorine family as HOCl. Research shows that they both kill bacteria, fungus, spores, and viruses. Yet bleach is highly irritating to the eyes, skin, and lungs— and inhalation over long periods could be carcinogenic.  In contrast, HOCl has a temporary and mild chlorine smell that dissipates quickly, it is non-irritating, and it does not have poisonous side effects. Alcohol is a popular disinfectant to use in clinic for wiping down instruments, furniture, and is a key ingredient in hand sanitizers. Ethyl alcohol (70%) is considered more effective compared to isopropyl alcohol. Both are bactericidal, fungicidal, and viricidal but are not effective against bacterial spores.
Hand sanitizers with alcohol are used daily in many medical offices, but over time repeated use may lead to hand dermatitis. I became allergic to hand sanitizers after using it for many months in clinic. It was extremely irritating and embarrassing to have a rash on my hands. After discontinuing hand sanitizers and using latex free gloves, it still took months for my hand dermatitis to resolve. In one study, the prevalence of contact dermatitis related to hand hygiene ranged from 25 to 55 percent.  Fortunately, HOCl acid can also be used in place of hand sanitizer with no irritating side effects. Moreover, punch HOCL delivers to pathogens is more powerful than the one delivered by alcohol.    

 

Manufucturing HOCl

If hypochlorous acid is such a powerful weapon against germs, why isn’t it more widely used? There are a couple of reasons, one being the cost to manufacturers. HOCl was very cost prohibitive until recently. Also, HOCl is stable for only a very short time before it became saltwater.  Technology has corrected this problem over the years and now, HOCl can remain stable for years and it is less costly to create.  There are currently three different ways to synthesize HOCl. It is highly unstable when isolated in pure form and therefore can only exist in solution. One method to create HOCl is to electrolyze water and sodium chloride. However, this method can be tricky to manufacture. The easiest method is the acidification of hypochlorite (HCl), a chemical also used in manufacturing bleach and is readily commercially available. The most difficult method is to add gaseous chlorine to induce hydrolysis. It requires the use of chlorine gas, a highly toxic chemical that is problematic to manipulate. 

Hypochlorous acid’s Kryptonite

The pH level of HOCl is its Kryptonite. The pH of the solution must be maintained between a range of 3 to 6 in order to maintain a proper concentration of HOCl. When the pH is outside of this range, dissociation occurs. A higher pH will have more hypochlorite (OCl-) in the solution, whereas a lower pH will produce a higher concentration of chlorine (Cl2). The powerful effect against pathogens is concentration dependent on HOCl. To prevent its dissociation, the optimal pH range must be maintained. Another study found HOCl lost its stability when exposed to ultraviolet light, sunshine, air, and higher temperatures (≥77°F).   Some HOCl products last for a month once the bottle is opened. Some need to be stored in a glass opaque bottle to ensure stability. Therefore, it is important to read the manufacturer’s instructions on whether an open bottle affects the expiration date. 

 

Hypochlorous acid’s role in optometry

Avenova was the first company to recognize HOCl’s potential in fighting germs. Since then, other companies have jumped on the bandwagon and are available without a prescription: Bruder Hygienic Eyelid Solution, Heyedrate Lid and Lash Cleanser, Ocusoft Hypochlor, Pure & Clean Lid Prep Vision Source, Theratears Sterilid Antimicrobial Eyelid Cleanser & Facial Wash, and We Love Eyes Hypochlorous Eyelid & Eyelash Cleansing Spray.

 

A recent study tested HOCl’s effect on decreasing the bacterial load on the periocular skin. After 20 minutes, a single application of 0.01% HOCl decreased staphylococci by 99.6 percent on 71 eyes. Repeated applications are important because recolonization of bacteria occurs rapidly.

 

HOCl has also been shown to be effective against epidemic keratoconjuntivis (EKC) in a small case study. There were 14 cases of EKC treated with 0.008 percent HOCl four times a day. Patients showed improvement in signs and symptoms.9 In contrast, HOCl was not shown to be effective against demodex in Kabat’s study published this past July.10
 

HOCl is a powerful force of nature against pathogens. It has multiple uses as an effective disinfectant both inside and outside of optometry. Yet, the fact that it is non-toxic and safe in application is a powerful combination that deserves consideration in patient care as well as in disinfection protocols in office.
