Do masks work? Your guess is as good as anyone’s. Here’s an answer I like, from Dr. Steven Novella, an academic clinical neurologist at the Yale University School of Medicine: “Wear the mask properly, but act as if the mask does not work.”

What if you could easily add a second line of defense? Provide some protection in your nose and throat where the virus first settles in?

It has been suggested that toothpastes, mouthwashes and nasal rinses might mitigate the virus. A study published in the Journal of Medical Virology found that multiple mouthwash and oral rinse products wiped out a human coronavirus closely related to the SARS-CoV-2 virus in a laboratory.

Because the mouthwash and hydrogen peroxide oral rinses in the study are widely available and easy to use, “I would recommend the use of the rinses on top of wearing mask and social distancing. This could add a layer of protection for yourself and others,” said lead study author Craig Meyers, PhD, professor of microbiology and immunology and obstetrics and gynecology, Penn State College of Medicine in Hershey, Pennsylvania.

“This study adds to and further confirms the recently published evidence from virologists in Germany that mouthwashes can inactivate the virus that causes COVID-19 in a test tube,” Valerie O’Donnell, PhD, co-director of the Systems Immunity Research Institute of Cardiff University, Cardiff, Wales, said when asked to comment on the study.

That study was in a lab, not in human bodies. Other doctors advocate nasal rinses.

The nasal lining serves an important role in the innate immune system, providing a primary defense against inhaled viruses, bacteria, and other particulates. This lining, consisting of a superficial mucus layer atop an aqueous base, traps inhaled particulates that are then propelled by underlying cilia into the nasopharynx. They are ultimately driven into the gastrointestinal system, where they are destroyed. Topical nasal rinses take advantage of this secretory lining in multiple ways. First, nasal rinses physically disrupt the viscous surface layer, removing the mucus and its associated particulate matter. Additionally, the presence of nasal saline helps to increase hydration of the deeper aqueous layer, simultaneously improving the underlying ciliary beat frequency and reducing local inflammatory mediators. This can be particularly helpful during a viral respiratory infection, in which there is resultant mucociliary dysfunction and mucostasis that occurs secondary to the inflammatory response.

Let me warn you: You can’t just go snorting povidone iodine, hydrogen peroxide or anything else. You can hurt yourself. The concentrations of these things on the market are much too strong for your nose or mouth. They need to be carefully diluted. I first thought that I could swab my nose with hydrogen peroxide on a Q-tip: Nope. Moreover, if you’re doing a nostril rinse you can easily spread the virus. Get a doctor’s advice.

I take a zinc losenge before going into the supermarket. There is evidence that this can help. Dr. Ian Tullberg, a board-certified urgent care and family practice physician at University of Colorado Health, says these may work, but it’s too early to know for sure.

Again, too much zinc can be harmful.

But be careful. More than 150mg/day of zinc may lead to zinc toxicity, with side effects including reduced immune function, according to the NIH. That could leave you worse off than when you started.

These home remedies are like any other medicine: They might work for some but not for others. And they can easily by overdone, creating more problems than they solve.

“Curiouser and curiouser!” cried Alice.

The more cases of Kung Flu we see, the more damage we see. Members of Survivor Corps, which has more than 100,000 members on social media, reported 98 ailments — eight times more than what the CDC has listed.

Following is a sampling of what Mao’s Malaise can do to the body.

The Great Invader: How COVID-19 Attacks Every Organ. We have underestimated and misunderstood COVID-19 since it first appeared.

It can be a gastrointestinal disease causing only diarrhea and abdominal pain. It can cause symptoms that may be confused with a cold or the flu. It can cause pinkeye, a runny nose, loss of taste and smell, muscle aches, severe fatigue, diarrhea, loss of appetite, nausea and vomiting, whole-body rashes, and areas of swelling and redness in just a few spots.

In a more severe disease, doctors have also reported people having heart rhythm problems, heart failure, kidney damage, confusion, headaches, seizures, brain inflammation, Guillain-Barre syndrome, and fainting spells, along with new sugar control problems, blood clots throughout the body, and severe immune system responses. It’s not just a fever and coughing, leading to shortness of breath, like everyone thought at first.

Here’s a look at the coronavirus’s complicated journey through the body. Patients with severe symptoms are developing damage in various organs, from the kidneys to the heart. From the very first cases of the novel coronavirus reported in China, doctors knew the virus targeted the lungs. But now, doctors are seeing patients with severe symptoms who are developing other damage around the body — from the kidneys to the heart.

COVID-19 Autopsies Reveal Ravages of ‘Terrible, Terrible’ Disease. COVID-19 has proven in some ways to be as mystifying to pathologists examining the dead as to physicians treating living patients.

“I was surprised at how bad it was,” Amy Rapkiewicz, MD, chair of the Department of Pathology at NYU Langone Health’s Winthrop Hospital in Mineola, New York, told Medscape Medical News. “The degree of respiratory disease was some of the worst I’ve ever seen,” she said. “It’s a terrible, terrible disease. Every organ in the body is pretty much affected.”

It’s a genetic luck of the draw. Here is some explanation:

Genetic or immune defects may impair ability to fight Covid-19.

Genetic or immune defects may impair ability to fight Covid-19. A significant proportion of patients who develop life-threatening forms of Covid-19 have genetic or immunological defects that impair their ability to fight the virus, research has found. The Covid Human Genetic Effort international consortium describes two glitches in severely ill Covid-19 patients that prevent them from making a frontline immune molecule called type 1 interferon. The patients would have carried these glitches for years before the pandemic, or in the case of the genetic errors, all their lives. The discovery may help to explain a mystery surrounding the coronavirus: why it leaves some sufferers sick or dying in intensive care, while others remain barely affected or asymptomatic.

Defects in early immune responses underlie some severe COVID-19 cases.

COVID-19 kills some people and leaves others relatively unscathed. But why? Age and underlying health conditions are risk factors, but scientists are trying to tease out other differences, including in people’s genes or immune systems, that may play a role. Two new studies show that flaws in the body’s early response to viral infection, one caused by genetic defects and one by traitorous immune responses, are behind some severe COVID-19 cases.

In one study, published online September 24 in Science, researchers identified certain genetic defects in some people with severe COVID-19 that make the body produce fewer interferons, proteins that are part of the immune system’s early warning system. In other people with severe disease, however, the body’s own immune responses disable interferons, a second study published online in Science the same day finds.

Covid-19 scientists flag key immune function as a turning point in life threatening cases.

Genetic analysis of Covid-19 patients published in the same journal revealed two dozen gene mutations that had been “silent” until patients were infected by SARS-CoV-2. Researchers — many of them also involved in the antibody study — sequenced the genomes of 659 patients with life-threatening cases of the disease; 3.5% carried genetic variations that inhibit interferon production.

Those genetic flaws were similar to the ones that Hoischen and his colleagues from a dozen Dutch centers described in the Journal of the American Medical Association two months ago. The two sets of brothers had inherited a gene mutation that impaired the interferon response, keeping their immune systems from fighting the coronavirus until it had replicated for days.

Regular exercise may reduce the risk of acute respiratory distress syndrome, a major cause of death in patients with the COVID-19 virus, a top exercise researcher reports.

A review by Zhen Yan of the University of Virginia School of Medicine showed that medical research findings “strongly support” the possibility that exercise can prevent or at least reduce the severity of ARDS, which affects between 3% and 17% of all patients with COVID-19. Based on available information, the federal Centers for Disease Control and Prevention estimates 20% to 42% of patients hospitalized for COVID-19 will develop ARDS. The range for patients admitted to intensive care is estimated at 67% to 85%.

Research conducted prior to the pandemic suggested that approximately 45% of patients who develop severe ARDS will die.

This involves an antioxidant called EcSOD that is produced by the body.  Research suggests that even a single session of exercise increases production of the antioxidant.

“Our findings suggest aerobic exercise is particularly potent in stimulating EcSOD expression,” Yan wrote in an email to Newsweek. “With that said, weight training helps maintain or even increase muscle mass. More muscle mass will likely lead to more EcSOD production, hence more benefits. “Aerobic exercise can be easily done at home, such as [a] stationary bike, aerobic floor exercise and rowing machines. Of course, canoeing, biking and running outside with strict social distance are good options.”

Maybe. If you do it right.

A leading scientist says: Inhale through your nose and exhale through your mouth. Breathing this way can help the body fight viral infections.

The reason is that your nasal cavities produce the molecule nitric oxide, which chemists abbreviate NO, that increases blood flow through the lungs and boosts oxygen levels in the blood. Breathing in through the nose delivers NO directly into the lungs, where it helps fight coronavirus infection by blocking the replication of the coronavirus in the lungs.

The scientist is Louis J. Ignarro, Distinguished Professor Emeritus of Molecular & Medical Pharmacology, School of Medicine, University of California, Los Angeles. He is one of three pharmacologists who won the Nobel Prize in 1998 for discovering how nitric oxide is produced in the body and how it works.

NO protects your blood vessels, which we now know are attacked by the virus.

NO is produced continuously by the 1 trillion cells that form the inner lining, or endothelium, of the 100,000 miles of arteries and veins in our bodies, especially the lungs. Endothelium-derived NO acts to relax the smooth muscle of the arteries to prevent high blood pressure and to promote blood flow to all organs. Another vital role of NO is to prevent blood clots in normal arteries.

It also directly attacks the virus.

Other types of cells in the body, including circulating white blood cells and tissue macrophages, produce nitric oxide for antimicrobial purposes. The NO in these cells reacts with other molecules, also produced by the same cells, to form antimicrobial agents to destroy invading microorganisms including bacteria, parasites and viruses. As you can see, NO is quite an amazing molecule.

The sinuses in the nasal cavity, but not the mouth, continuously produce NO. This NO  is chemically identical to the NO used clinically by inhalation. So by inhaling through the nose, you are delivering NO directly into your lungs, where it increases both airflow and blood flow and keeps microorganisms and virus particles in check.
