First Principles to prevent COVID-19 infection

This article is based upon information from several sources, and it does not involve vaccines or drugs to prevent COVID-19 infection. The principles are science-based and the sources are identified, and links to research is included where available. Read the Disclaimers at the end of the article for important information.

First Principles

Principle 1 – Avoid Contact
Social distance at least 6 feet when near people you don’t know.  More distance is better. Wear effective masks, with double-layer masks highly recommended.

Principle 2 – Destroy COVID-19 at the major points of entry, which are the nasal cavities and the salivary glands/mouth.

Principle 3 – increase your immune function through healthy foods and key supplements

The information provided below is based upon several scientific studies that show what YOU can do to protect yourself against serious COVID-19 infection using caution and items readily available at your local grocery or pharmacy.  

1) The CDC recommends social distancing when in groups of people that may be carriers of COVID-19 virus.  Social distance has been defined as 6 feet of separation. More is better.

The American Medical Association (AMA) advises those in crowded situations to Wear an effective mask that preferably has two layers.  You can wear at least two layers of a non-woven mask or put a surgical mask in front of a cloth mask.  Single layer cloth masks do not offer much protection due to inability to stop COVID-19 aerosol particles.

2) Penn State University has thoroughly researched how to reduce viral load in the nasal cavities and salivary glands/mouth by irrigating the nose with dilute baby shampoo for 2 minutes and using anti-viral mouthwash for 30 seconds. The article was published in the Journal of American Virology in July, 2021. The procedures described in the university’s research reduce COVID-19 viral load by 99.9%, which is a significant reduction in the risk of infection. Tilting the head back when irrigating the nasal cavities or gargling anti-viral mouthwash to clear the salivary glands/mouth allows for more effective access to the COVID-19 in these areas.

There is an alternate method to the of reducing the viral load approach to irrigating the nasal cavities and salivary glands/mouth. A 10% solution of Betadine is commonly available at pharmacies, which is a solution that uses povidone-iodine as the anti-viral agent. It must be diluted to a less concentrated 1% Betadine solution before irrigating the nose. Dilution to ~1% requires addition of sterile water and it can stain teeth when used in the mouth. Swabbing the nose with 10% Betadine will not be as effective as irrigation using 1% Betadine or the 1% diluted baby shampoo because the nasal cavities extend beyond where an anti-viral treated swab can reach.

The research on using providone-iodine to reduce viral load in the nasal cavities and salivary glands was done in India and republished by a division of the NIH. This research to also use dilute providone-iodine is a randomized study that shows the effects of using providone-iodine to reduce COVID-19 infection. It was published by Bioresearch Communications.

3) Wear an efficient mask if you are in a situation that does not allow social distancing. 
The best masks are N95 or K95 masks, but they are expensive.  The most commonly available masks are non-woven fabric and they stop particles that are ~0.3 microns or larger.  COVID-19 that has been converted into an aerosol form is ~0.1 microns. Doubling two non-woven masks has been shown to increase the capture of COVID-19 aerosol particles. Any mask is better than no mask, but cloth masks do not do as an effective job of stopping aerosol virus particles as the N95 K95 masks, or single or doubled non-woven surgical masks. 

4) Taking vitamin D improves the immune response in early infection of COVID-19. This is a direct quote from a scientific study of how vitamin D improves immune function.

Scientific studies of Vitamin-D has been shown to influence both innate and adaptive immunity during infections. It modifies macrophage and monocyte activity, reducing the circulating levels of pro-inflammatory cytokines. Vitamin-D has been also shown to influence human adaptive immune response of T-cells, promoting a humoral Th2 as opposed to the Th1, which is also linked to pro-inflammatory cytokine release. Moreover, it has direct antiviral properties, particularly against enveloped respiratory viruses”.

The Front-Line COVID-19 Critical Care Alliance (FLCCC) recommends 1,000 to 3,000 IU of Vitamin D per day, and 500 to 1,000 mg of Vitamin C twice per day. There is a link to an article by this author titled Your Immune System is Your Best Defense Against Diseases. Links to various sources related to increasing immune function includes the Cleveland Clinic and similar sources.


If you follow these steps, you are at significantly lower risk of experiencing a major COVID-19 infection.
