Coronavirus May Reproduce in Eyes for Weeks

Information about the SARS-CoV-2 virus continues to unfold. Since this virus has never been seen before, researchers are scrambling to understand the infection and mortality rates, how it spreads and how it can be treated.

Engineers from Johns Hopkins1 created an online digital database that gets updated every day with the number of confirmed cases, deaths and the total number of tests conducted for reporting countries. The mortality rate can be found by taking the total number of deaths and dividing by the total number of confirmed cases.

This has been the percentage of deaths reported in the news. However, the number is not accurate because states have not had the resources for mass COVID-19 testing.2 Most of those tested have also presented with symptoms, so it’s unknown how many may have had and recovered from COVID-19, but were unaware when they had mild or no symptoms of infection.

From late March to early April 2020, all pregnant women entering New York–Presbyterian Allen Hospital and Columbia University Irving Medical Center to deliver their babies were screened for SARS-CoV-2.3 The results revealed that 87.9% who tested positive had no symptoms.

Results from a separate round of testing4 at a homeless shelter in Boston showed that 36% tested positive but, of those, only 7.5% had a cough, 1.4% had shortness of breath and 0.7% had a fever. If the percentage of people in the general population who are infected without symptoms is just half of the 87.9% tested in New York, it significantly reduces the mortality rate, since it increases the number who will test positive.

This would mean that the published mortality rates are far from accurate, as most of the testing now is on people who have symptoms, which artificially elevates the rate and skews the statistics.

SARS-CoV-2 Found One Week After Infection Cleared

Researchers know most human-to-human transmission has been through respiratory droplets. However, other routes are still under investigation, including exposure to feces and blood.5 While some patients with COVID-19 present with conjunctivitis, data on viral replication in eye samples has been sparse.

During the SARS-CoV-1 pandemic, exposure to eye fluid was associated with an increased risk of transmission and infection. A new case study published in the journal Annals of Internal Medicine6 indicates that coronavirus may live in eye fluid long after the infection appears to have cleared.

Researchers used data gathered from a 65-year-old woman who had traveled from Wuhan, China, to Italy in late January and was the first confirmed case in Italy.7 She was admitted to the hospital six days after arriving in the country.

Doctors report that she had conjunctivitis on the day of admission to the Roman hospital, Lazzaro Spallanzani National Institute for Infectious Diseases.8 After the third day her eye was swabbed because the condition was not improving. Samples were collected almost daily after SARS-CoV-2 was detected in the fluid. The conjunctivitis appeared to have improved by Day 15 and resolved by Day 20.

The testing showed declining concentration of the virus through Day 21. By Day 22 the virus was not detectable. Yet, five days later it was again found in a sample from her eyes. The lab values suggest the virus continued replicating in the conjunctiva. Further testing revealed it was infectious and could represent a source for infecting others.

Conjunctivitis — One Symptom of COVID-19

Symptoms of conjunctivitis have “occasionally been reported”9 with COVID-19, in much the same way other types of coronaviruses are associated with conjunctivitis.10 However, it was not associated with SARS-CoV or MERS-CoV.

Viral conjunctivitis is extremely contagious and often self-limiting. The condition may develop after exposure to someone with an upper respiratory infection such as COVID-19, or it may develop after a virus spreads throughout the body along mucus membranes connecting the lungs, nose, throat and tear ducts.11

There is no treatment for viral conjunctivitis, which usually runs its course in two to three weeks. Antibiotics, ointments and drops are not effective, as the condition is caused by a virus rather than bacteria. Cold compresses and artificial tear solutions may help relieve the symptoms.

Speaking to a reporter from The Washington Post, infectious disease specialist W. David Hardy pointed out most people don’t always remember the connection between the nose and eyes.12

Symptoms of COVID-19 have included cough and shortness of breath.13 You should seek medical attention if you’re having trouble breathing or if you’re having persistent pain or pressure in your chest. If your lips or face are blue call 911. It’s also an emergency if someone has new confusion or if you’re unable to arouse them.

Recently, the Center for Disease Control and Prevention added six more conditions that may appear with SARS CoV-2.14 The symptoms of coughing and shortness of breath may appear within two to 14 days after having been exposed to the virus. The CDC said that people with these two symptoms or those who have at least two of the following may have COVID-19:15

Fever

Repeated shaking with chills

Chills

Muscle pain

Headache

Sore throat

New loss of taste or smell

What Is Conjunctivitis?

There is a thin layer of tissue lining the inner surface of the eyelid and the white part of the eyes. This is called the conjunctiva. When it becomes inflamed or swollen the condition is called conjunctivitis, which you may know as pink eye. It’s especially common in children but can happen in adults.16 Conjunctivitis can be caused by a virus, bacteria or chemical irritant and symptoms include:

  • A gritty feeling, itching or burning in the affected eye
  • Excessive tearing and discharge
  • Swollen eyelids
  • An increase in light sensitivity

The name “pink eye” comes from the final symptom, which is a pink discoloration in the affected eye, including the whites of the eye. Adults and children who have allergic reactions to pollen, smoke, chlorine or ingredients in cosmetics may also have symptoms of conjunctivitis after exposure.

Allergic conjunctivitis will happen more commonly if you suffer from seasonal allergies. The condition develops when the allergic protein contacts the eye. Chemical conjunctivitis may be triggered by exposure to noxious chemicals or airborne pollutants.

If you frequent chlorinated swimming pools, the chlorine can sometimes trigger chemical conjunctivitis. If you wear contact lenses, you need to temporarily stop wearing them and possibly switch to a different type of disinfection solution.

As conjunctivitis is highly contagious, it’s important to keep your hands away from your eyes since you can spread the infection to other people. Wash your hands thoroughly and frequently and change your towels daily. Throw out any eye makeup and never share eye makeup with others.

New Information Has Implications for Preventing the Spread

Several others have also found the SARS coronavirus can live in eye fluid. However, as Hardy noted, the area more frequently affected is the throat and lungs, where it can cause serious damage. Hardy told a reporter from The Washington Post:17

“The cells that are inside the eye are similar but not the same. When it gets into the eye, it doesn’t cause nearly the same amount of destruction as it does to cells in the respiratory system.

The whole message that is important here is that you don’t touch your face until you get home, wash your hands and make sure your hands are clean before touching your face. You have to be extra vigilant and assume that everything out there could’ve been contaminated with fresh covid virus.”

The findings also have implications for health care workers. While it’s not necessary for the general public to use face shields, Aaron Glatt, from Mount Sinai South Nassau and spokesperson for the Infectious Diseases Society of America, told The Washington Post these findings may affect public health procedures.

However, he also believes more research is needed to gauge how many others can retain the virus in their eye fluid. The information also highlights the importance of avoiding touching your eyes, nose and mouth, as well as frequently washing your hands using a good technique.18 Roman researchers concluded:19

“A related implication is the importance of appropriate use of personal protective equipment for ophthalmologists during clinical examination, because ocular mucosa may be not only a site of virus entry but also a source of contagion.

Furthermore, we observed that ocular involvement of SARS-CoV-2 may occur early in the COVID-19 course, suggesting that measures to prevent transmission via this route must be implemented as early as possible.”

Prevent the Spread of Viruses and Protect Your Health

One study indicated that proper hand-washing helped reduce the spread of respiratory illnesses in incoming Navy recruits by 45%, demonstrating the power of keeping your hands clean.20 Research has shown that diligently washing your hands helps stave off infections, including respiratory illnesses.

So, the best thing to do is to be sure to follow the CDC’s advice and make good hand-washing a regular practice. Compare your hand-washing habits to the recommended techniques in “The Impact of Effective Hand-Washing Against Infection.”

In the past months I’ve covered several strategies you can use to help prevent getting infected or spreading the virus to others, including social distancing and keeping your hands away from your face. The CDC now recommends wearing cloth masks in public to avoid infecting others in case you are unknowingly carrying the virus.21

Additional steps you can take to protect your health can be found on my Coronavirus Resource Page, including combatting the virus by supporting your immune system and addressing your vitamin D levels. You can also find information about increasing your vitamin C, quercetin and zinc levels to help recover from influenza and SARS-CoV-2.

Vitamin D Level Is Directly Correlated to COVID-19 Outcome

There is strong scientific evidence vitamin D plays a central role in your immune response and your ability to fight infections. In this video, Ivor Cummins, biochemist and chief program officer for Irish Heart Disease Awareness, explains how recent studies supporting higher levels of vitamin D may reduce your risk of negative outcomes from COVID-19.

He also singles out some of the conditions associated with low vitamin D levels, such as low sun exposure, insulin resistance and high levels of inflammation.

In 2017, a review of randomized, double-blind, placebo-controlled trials using vitamin D2 or D3 was published in the BMJ.1 The data revealed vitamin D supplementation was “safe and it protected against acute respiratory tract infection overall.” They found people who were most deficient experienced the greatest benefit.

I am beyond excited to announce a groundbreaking new study by an organization that we have supported for over 13 years, GrassRootsHealth. Many of you have ordered their vitamin D test in the past, and the funds from that were used to do this clinical trial that could change the entire treatment strategy for COVID-19.

A recent clinical trial to investigate the efficacy of vitamin D against COVID-19 was announced April 3, 2020.2 Days later, Mark Alipio — who received no funding for his work — published a preprint letter3,4 in which he released data from an analysis of 212 people with lab-confirmed COVID-19 and for whom there were serum 25(OH)D levels available. You can read Alipio’s full study here.

Using a classification of symptoms based on previous research, he employed statistical analysis to compare the differences in clinical outcomes against the levels of vitamin D. Of the 212 people, 49 had mild disease; 59 had ordinary disease; 56 were severe and 48 were critical.

vitamin d covid-19 severity

In the initial study group of 212 patients (see Table 1 below), 55 had normal vitamin D levels, which Alipio defined as greater than 30 ng/ml; 80 had insufficient levels of 21 to 29 ng/ml and 77 had deficient levels of less than 20 ng/ml. Vitamin D levels were strongly correlated to the severity of the illness experienced. It is important to note that most experts consider 30 ng/ml half of what an optimum vitamin D level should be, which is 60 to 80 ng/ml.

descriptive statistics

Of the 49 with mild illness, 47 had normal vitamin D levels. For those of you who are not good with math that means that 96% of the patients with mild illness had “normal” levels of vitamin D. Note again this “normal” level was above 30, and most experts would raise that to 60.

Of the combined 104 with severe or critical illness, only four had normal levels of vitamin D. That is 4% or the reciprocal of the mild group. How much stronger a correlation could one hope for? Alipio concluded:5

“… this study provides substantial information to clinicians and health policy-makers. Vitamin D supplementation could possibly improve clinical outcomes of patients infected with Covid-2019 based on increasing odds ratio of having a mild outcome when serum (OH)D level increases. Further research may conduct randomized controlled trials and large population studies to evaluate this recommendation.”

Further Evidence Vitamin D Significantly Impacts Outcomes

The writers of a recent editorial in Alimentary Pharmacology & Therapeutics6 used a different metric, but arrived at similar results. They argued a marked variation in mortality occurs above or below 35 degrees North latitude. This is also the line above which it is not possible for people to get enough sunlight to retain vitamin D during the winter months.

When the mortality per million is plotted against latitude, the results suggest vitamin D plays a role in the outcome of infection with SARS-CoV-2. Data were gathered from countries reporting more than 150 people infected by April 15, 2020.

Although Nordic countries are far north of the demarcation line, vitamin D deficiency is also relatively low, potentially from widespread use of supplements. In countries where deficiency is common, such as Spain and Italy, mortality rates have been higher. The writers stress the importance of vitamin D on the outcome of infection, concluding that, while there is modest evidence, it protects against infection:7

“… the hypothesis is not that vitamin D would protect against SARS-CoV-2 infection but that it could be very important in preventing the cytokine storm and subsequent acute respiratory distress syndrome that is commonly the cause of mortality.”

A second paper8 published in April 2020 hypothesized that vitamin D protects the body against SARS-CoV-2 infections and sought to assess if there was an association between vitamin D levels and the number of COVID-19 infections. The data included only European countries and found a significant relationship between the mean (average) vitamin D level and the number of infections.9

People who were most vulnerable to this respiratory infection were the most deficient. They concluded the results support the advice to supplement with vitamin D to protect against the SARS-CoV-2 infection. These results support the 2017 review of studies published in the BMJ noted above.10

Yet another paper evaluated the role vitamin D deficiency plays in preventing respiratory infections and found similar results.11 The researchers wrote that vitamin D had “a significant protective effect” and reduced the risk of an acute respiratory infection from 60% to 32% in participants. The researchers also wrote vitamin D may help prevent respiratory infections and lower antibiotic use.

African-Americans Experiencing Higher Rates of Infection

A letter to the editor was then published in the BMJ, signed by 30 scientists from around the world, including Alipio.12 They pointed out the disproportionately high number of individuals who are Black, Asian and Minority Ethnic (BAME), or those living in care homes in the U.K. who die from COVID-19.

They also identified obesity as another risk factor, with co-morbid conditions including diabetes and cardiovascular disease. Each group of people — those living in care homes, BAME and obese — also tends to have lower levels of vitamin D.

The letter included the research results from Alipio’s preprint letter, indicating the 30 scientists agreed with how the data was collected and analyzed, as well as the conclusions. The group identified the lengthy process vaccines require and the 100 years of research on vitamin D.

They hypothesized that vitamin D has clinical relevance to COVID-19 and may reduce the number of fatalities. Although there is a need for clear clinical evidence with research, it’s important to note the widespread vitamin D deficiency, including the risk groups mentioned. They quote Dr. Hugh Sinclair, who nearly 100 years ago observed:13

“The deficiency of any nutrient which is essential for every tissue will eventually lead to abnormal function in every tissue. That is so incontrovertibly obvious that I am continually astonished it must be repeatedly forcefully restated.”

They then went on to give a reason for why vitamins have so often been overlooked:14

“Human nature is such that simple solutions to complex issues, for example vitamin C for scurvy, and hand washing prior to baby delivery, are often not readily embraced; but surely the scale and impact of the COVID-19 pandemic demands all avenues are fully explored; more so when no other effective treatment strategies as yet exist.

A safe simple step, the correction of a deficiency state, vitamin D this time, convincingly holds out a potential, significant, feasible ‘COVID-19 mitigation remedy.”

Others connect the heavy toll in the African-American community with an increased prevalence of obesity, diabetes and high blood pressure, which are risk factors for increased severity of COVID-19.15 In the states of Maryland and Louisiana and the metropolises of New York, Chicago and Washington, D.C., the percentages of BAME individuals dying from probable COVID-19 are higher than the percentages of BAME who live in the area.

However, while there is a correlation between the higher prevalence of health conditions that increase disease severity in the African-American population, there is also a higher prevalence of vitamin D insufficiency due to reduced production.16 Darker pigmentation produces less vitamin D with exposure to the sun.

Vitamin D in COVID-19 Treatment

Findings from The Irish Longitudinal Study on Ageing (TILDA)17 and a vitamin D review paper18 published in the journal Nutrients, April 2, 2020, also suggest vitamin D deficiency could have serious implications for COVID-19. As reported by Medical Xpress, April 6, 2020:19

“The report,20 ‘Vitamin D deficiency in Ireland — Implications for COVID-19. Results from the Irish Longitudinal Study on Ageing (TILDA),’ finds that vitamin D plays a critical role in preventing respiratory infections, reducing antibiotic use, and boosting the immune system response to infections.

With one in eight Irish adults under 50 deficient in vitamin D, the report highlights the importance of increasing intake … TILDA researchers recommend that adults over 50 should take supplements — not just in winter, but all year round if they don’t get enough sun …

Professor Rose Anne Kenny, principal investigator of TILDA, said: ‘We have evidence to support a role for vitamin D in the prevention of chest infections, particularly in older adults who have low levels. In one study Vitamin D reduced the risk of chest infections to half in people who took supplements.

Though we do not know specifically of the role of vitamin D in COVID infections, given its wider implications for improving immune responses … at-risk cohorts should ensure they have an adequate intake of vitamin D.'”

The second paper, published in the journal Nutrients, carries the telling title, “Evidence That Vitamin D Supplementation Could Reduce Risk of Influenza and COVID-19 Infections and Death.”21 As reported in the abstract:

“This article reviews the roles of vitamin D in reducing the risk of respiratory tract infections, knowledge about the epidemiology of influenza and COVID-19, and how vitamin D supplementation might be a useful measure to reduce risk. Through several mechanisms, vitamin D can reduce risk of infections.

Those mechanisms include inducing cathelicidins and defensins that can lower viral replication rates and reducing concentrations of pro-inflammatory cytokines that produce the inflammation that injures the lining of the lungs, leading to pneumonia, as well as increasing concentrations of anti-inflammatory cytokines …

Evidence supporting the role of vitamin D in reducing risk of COVID-19 includes that the outbreak occurred in winter, a time when 25-hydroxyvitamin D (25(OH)D) concentrations are lowest; that the number of cases in the Southern Hemisphere near the end of summer are low …

Vitamin D deficiency has been found to contribute to acute respiratory distress syndrome; and … case-fatality rates increase with age and with chronic disease comorbidity, both of which are associated with lower 25(OH)D concentration.

To reduce the risk of infection, it is recommended that people at risk of influenza and/or COVID-19 consider taking 10,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d. The goal should be to raise 25(OH)D concentrations above 40–60 ng/mL (100–150 nmol/L). For treatment of people who become infected with COVID-19, higher vitamin D3 doses might be useful.”

UK Recommends Supplementation

Public Health England is recommending their citizens take a vitamin D supplement while they are spending more time indoors.22 The National Health Service23 routinely recommends their citizens take a supplement during the fall and winter months. They also recommend a supplement all year round for those who aren’t outdoors, are in a care home, usually cover all their skin or have dark skin.

The chief nutritionist at Public Health England is concerned that Britons may not be getting enough vitamin D from sunlight as they spend more time indoors. They counsel their citizens that while an adequate amount of vitamin D cannot stop an infection, it does have benefits, including improved outcomes in those who are deficient.24

Yet, despite radical changes in the way people are living during the pandemic, the guidelines in the U.S. have not changed. The National Institutes of Health recommends that most people get their nutrients from food and beverages, including fortified food products. However, dietary intake is not sufficient to maintain healthy levels:25

“Dietary intake of vitamin D from natural foods traditionally plays only a minor role with few available natural sources: animal sources such as fatty fish, cod liver oil, or egg yolks contain vitamin D3, and fungal sources such as mushrooms and yeast exposed to sunlight or UV radiation contain vitamin D2 (ergocalciferol).”

The U.S. health agencies appear to have little interest in helping the public support their immune system through appropriate nutrition but would rather rely on drugs and vaccines.

Some Public Health Officials Recognize Value of Vitamin D

Although the official recommendation from government agencies is to wait for drugs and a vaccine, some are speaking out. Former CDC director Dr. Tom Frieden wrote an opinion piece for Fox News in which he suggests vitamin D may reduce COVID-19 mortality rates, especially in those who are deficient.26

He goes on to say supplementation has reduced the “risk of respiratory infections, regulates cytokine production and can limit the risk of other viruses such as influenza.” Much of the damage from COVID-19 occurs with a “cytokine storm,” during which the body’s inflammatory system goes into high gear, damaging organs and increasing mortality rates.

The evidence of seasonality of some viral infections may be related to vitamin D production that declines during the winter months. Seasonal changes in infection rates are more evident in northern climates, and little or none in areas that are warm all year. He concluded:27

“We can do lots of things to improve our resistance to infection. These include getting regular physical activity, getting enough sleep, stopping smoking and other tobacco use, and, for people living with diabetes, getting it under control. Taking a multivitamin that includes Vitamin D, or a Vitamin D supplement, probably can’t hurt, and it might help.

As we continue to work to mitigate the impact of COVID-19, anything we can do to strengthen our resistance is a step in the right direction.”

Dr. John C. Umhau is a public health specialist at the National Institutes of Health. In an article in MedPageToday he referenced his review in which he argued there were groups who were more likely to have vitamin D deficiency, including those who are obese, the elderly and those with dark skin. Yet vitamin D is one of the:28

“most studied and most important host factor impacting survival from COVID-19 … A government-sponsored research strategy to address this issue has not been developed, as officials explained that there was no mandate to explore an alternative to the existing vaccination program.

However, other researchers picked up the ball and provided convincing evidence that vitamin D could reduce the incidence of acute respiratory infection.”

In further evidence published in Nutrients,29 scientists reviewed how vitamin D can reduce the risk of infection by lowering the rate at which the virus replicates and reduce the pro-inflammatory cytokines that damage the lungs, leading to pneumonia. Vitamin D also helps increase concentrations of anti-inflammatory cytokines that may help protect the lungs. The researchers recommended those at risk take:

“10,000 IU/d of vitamin D3 for a few weeks to rapidly raise 25(OH)D concentrations, followed by 5000 IU/d. The goal should be to raise 25(OH)D concentrations above 40–60 ng/mL (100–150 nmol/L).”

Individuals Dosages Vary Widely — Test To Be Sure

Although the researchers recommended a specific amount of vitamin D3 to take, it’s impossible to predict how much supplementation you personally may need unless your blood level is measured. Typically, ranges are from 2,000 to 10,000 units (IUs) per day, but there are many variables that contribute to this dose — that is why testing is so important.

By testing at home you can stay away from hospitals unless you’re having symptoms of a worsening respiratory infection, such as difficulty breathing. Ideally, you’d like your level to be 60 ng/mL.

GrassrootsHealth makes testing easy by offering an inexpensive vitamin D testing kit as part of its consumer-sponsored research. All revenues from these kits go directly to GrassrootsHealth. I make no profit from these kits and only provide them as a service of convenience to my readers.

Interesting Note on Fauci and Vitamin D

As reviewed in an earlier article, long before SARS-CoV-2 became part of everyday life, Dr. Anthony Fauci, director of the National Institute of Allergy and Infectious Diseases (NIAID), believed vitamin C and D were important strategies for enhancing your body’s immune system. Just four years ago, he was interviewed by a reporter from Washingtonian on how to avoid getting sick.

He explained the importance of washing your hands, clipping your nails and getting enough sleep. A fourth strategy he discussed was using vitamin C and D supplements:30

“It can enhance your body’s defense against microbes. I take 1,000 milligrams a day. Many people also do not get enough vitamin D, which affects a lot of body functions, so that would be helpful, too.”

In the current pandemic, the U.S. has placed inexpensive, patent-free nutritional supplements in second place to drugs and vaccines, which come with a high price tag in addition to unwelcome side effects.

In a more recent interview with RealClearPolitics, Fauci appeared to hedge his opinion. He stressed the viability of vitamin C as an antioxidant that’s “essentially totally harmless unless you take in a ridiculous amount.”

But when asked whether vitamin D might mitigate some respiratory infections, he said: there’s “no definitive proof.” He did point out, though, that you’re not likely to get hurt by it.31 Still, his answers suggest an unwillingness to admit vitamin D plays a proven and important role in infectious disease.

Might Fauci’s backpedaling on vitamins C and D have anything to do with the fact that he serves on the Leadership Council for the Bill & Melinda Gates Foundation’s Global Vaccine Action Plan? He describes his litmus test for safety and effectiveness as being tied to randomized control trials:32

“That’s why you keep hearing me over and over again saying the best optimal way is to do a randomized control trial to determine as quickly as possible whether something works, and if it does, get it out there. If it doesn’t, get it off the table.”

In what appears contradictory to this statement, Fauci said a vaccine may be released in the next 12 to 18 months.33 However, the standard steps to develop a relatively “safe” vaccine averages five years. It begins with two to four years of laboratory research, followed by one to two years of preclinical studies, and then Phase I, II and III trials.34
