Information You Should Know about COVID-19

By August 29, 2020No Comments
Even though COVID-19 is a three stage illness, the CDC has only given treatment guidelines for Stage 3. However, treatment should begin as soon as people test positive, even if they are only in Stages 1 or 2. With 90% of viral load in the nose, people should treat the illness in its early stages with a nasal spray like Xlear to help defend against the virus and regain their health faster.
Treatment through the nose isn’t a novel or unproven method. Here are a few studies, articles, and links that will help you understand the most common sense way to treat COVID-19.


Utah State University COVID-19 Study

Virucidal Activity of Xlear Compounds vs SARS-CoV-2 Virus and Rhinovirus-16

Jonna B. Westover, Ph.D., Utah State University, Institute for Antiviral Research


At Utah State University’s Institute of Antiviral Research, Dr. Jonna Westover, Ph.D., and her team performed various studies to identify if Xlear Nasal Spray had any effect on COVID-19.


The study compared the possible effect of two Xlear nasal sprays, Chlorhexidine, and ethanol, on the COVID-19 virus. Water was used as a control. The two Xlear Sprays were: original Xlear Nasal Spray (saline and xylitol alone) and Xlear Rescue (saline and xylitol with added essential oils). The results were outstanding. Each of the Xlear nasal sprays reduced the virus to an undetectable amount. Chlorhexidine had a negligible effect on the virus.

Why Is this Important?

With government agencies and pharmaceutical companies pumping so much money and energy into finding a solution for COVID-19, this study shows a simple, safe, and cost-effective option that could help people be healthy amidst the pandemic.


COVID-19’s Three Stages and Possible Long-Lasting Effects

A Pathophysiological Perspective on COVID-19’s Lethal Complication: From Viremia to Hypersensitivity Pneumonitis-like Immune Dysregulation

Marcos A. Sanchez-Gonzalez, Dave Moskowitz, Priya D. Issuree George Yatzkan, Syed A. A. Rizvi, and Kenneth Day; Infect Chemother. 2020; 52:e31. Published online Jul 15, 2020.


In this paper, researchers argue for the need to treat COVID-19 in its early stages to mitigate potential damage to the lungs.


Researchers have observed similarities between COVID-19 and hypersensitivity pneumonitis (HP), a disease that affects the lungs. HP causes inflammation in lung tissue, difficulty breathing, and irreversible lung scarring if left unchecked. The medical community has seen these same symptoms with COVID-19. Both illnesses also have three stages of progression. The authors of this article highlight the need to treat COVID-19 early on, like one would for HP.

Why Is this Important?:

The CDC guidelines provide little direction for treatment in the early stages of COVID-19. However, this is a very important time to have treatment in order to reduce serious, long-lasting effects. Washing the nose with Xlear Nasal Spray is a crucial step in staying healthy and curbing COVID-19’s progression into later stages.

UNC Chapel Hill Study – Mapping COVID-19

SARS-CoV-2 Reverse Genetics Reveals a Variable Infection Gradient in the Respiratory Tract

Yixuan J. Hou, Kenichi Okuda, Caitlin E. Edwards, Scott H. Randell, Richard C. Boucher, Ralph S. Baric, et. al; Cell. Volume 182, Issue 2; published online May 26, 2020.


Through this study, researchers wanted to have a clearer idea of how one contracts COVID-19, and how the infection progresses through the body. They were able to map how the COVID-19 infection travels through the body.


Researchers found that the COVID-19 virus first infects the nasal cavity and firmly establishes itself there before moving to the respiratory system in later stages.

Why Is this Important?:

As one of the senior co-authors stated, “If the nose is the dominant initial site from which lung infections are seeded…therapeutic strategies that reduce virus in the nose, such as nasal irrigation or antiviral nasal sprays, could be beneficial.” This study shows that administering treatment through the nose is the best way to treat COVID-19, especially in its early stages.

New England Journal of Medicine Correspondence – Viral Load in the Nose

SARS-CoV-2 Viral Load in Upper Respiratory Specimens of Infected Patients

Lirong Zou, M.Sc., Feng Ruan, M.Med., Mingxing Huang, Ph.D., et. al, N Engl J Med 2020; 382:1177-1179; March 19, 2020.


In this correspondence, researchers shared their findings about where the highest viral load is in the body with people suffering from COVID-19.


After analyzing swabs taken from participants’ throats and noses, researchers found that there was a higher viral load in the nose.

Why Is this Important?:

These findings support the idea that initial treatment should take place in the nose, since that is where the virus resides and establishes itself.

Interview with Dr. Gustavo Ferrer

Former WHO Researcher, Founder of the Cleveland Cough Clinic, and Head of Two ICUs in Florida

Gustavo Ferrer, MD, is leading the charge to find a simple, cost-effective way to treat COVID-19. He helped conduct the study at Utah State University researching if Xlear would affect the COVID-19 virus. The researchers found that the virus was reduced to an undetectable amount in 15 minutes. This study was also replicated at Geneva University. Dr. Ferrer is now rolling out clinical trials in a multi-channel, international study. He has been interviewed on nationally syndicated news networks about his research and protocols regarding COVID-19.

Other Support for Treating COVID-19 through the Nose

Here is a list of other nasal sprays, or nasally applied options that are being developed. We are following the progress of these products, and as they advance, we will share any info on them that we can. The reason we shared all this info about Xlear is it is the only nasal spray on the market (over 20 years) that has been shown to even have a virucidal effect against COVID-19 in vitro.
