If you thought the publication of positive hydroxychloroquine studies would stop the blatant and reprehensible censorship of this COVID-19 remedy, you were wrong. It’s only getting worse.

July 27, 2020, America’s Frontline Doctors, a group of physicians who have organized to counteract the false narrative that hydroxychloroquine is dangerous and shouldn’t be used for COVID-19, held a press conference outside the Supreme Court of the United States.

After The New York Times filed a complaint with Facebook,1 the video was quickly scrubbed from YouTube and social media platforms, but you can find an archived copy of the transcript2 here. Donald Trump Jr., President Trump’s son, even had his Twitter account suspended for 12 hours after posting the video.3

During the hours it was available, the video garnered more than 14 million views and in excess of 600,000 shares. Speaking for the group were the founder, Dr. Simone Gold, and Drs. Bob Hamilton, Stella Immanuel, Dan Erickson, Joe Ladapo and James Todaro.

Frontline Doctors Speak Out, Crushing the Fear Narrative

After their first press conference was censored, the group held a second press conference4 the following day, blasting Facebook, Twitter and YouTube for their unwarranted censorship of medical information that can save lives and provide relief from the fear gripping the nation.

The group believes it is crucial we begin to balance the fear of the virus against what we know about its progression, treatment and survivability. The physicians that are part of this group first and foremost want everyone to have hope, and to realize that effective treatment is available and that very few people need to die, even if they are infected and develop symptoms.

“We implore you to hear this because this message has been silenced. There are many thousands of physicians who have been silenced for telling the American people the good news about the situation — that we can manage the virus carefully and intelligently. But we cannot live with this spider web of fear that’s constricting our country,” Gold said in the first press conference.

Immanuel, a primary care physician in Houston, Texas, reviewed her personal successes with the hydroxychloroquine regimen, saying she’s treated more than 350 patients with COVID-19, including patients with comorbidities that place them at increased risk for severe illness, complications and death. None has died.

“The result has been the same. I put them on hydroxychloroquine, I put them on zinc, I put them on Zithromax, and they’re all well,” Immanuel said.

Prophylactic Use of Hydroxychloroquine

They also stress that hydroxychloroquine in combination with zinc — just one 200 milligram tablet of hydroxychloroquine every other week with daily zinc — is an effective prophylactic that could be given to anyone at high risk of infection. Immanuel noted:

“I’ve put myself, my staff, and many doctors that I know, on hydroxychloroquine for prevention, because by the very mechanism of action, it works early and as a prophylaxis. We see 10 to 15 COVID patients every day. We give them breathing treatments. We only wear surgical mask. None of us has gotten sick. It works.”

People that might benefit from prophylactic use would include high-risk individuals such as teachers and the elderly. This could facilitate the safe reopening of schools and businesses everywhere.

Children, they point out, are at extremely low risk from the infection, rarely display symptoms, and are very inefficient transmission vectors. Parents rarely contract the infection from their children.

Hydroxychloroquine Is NOT a Magic Bullet

It is also very important to understand that while hydroxychloroquine is a useful tool, it must be used very early in the course of the illness, ideally immediately after exposure, because it works on slowing down viral replication. If the virus has already multiplied, the horse is out of the barn and hydroxychloroquine will likely be ineffective later in the course of the illness.

It’s also worth noting that in areas where hydroxychloroquine is hard to get a hold of, quercetin is likely a more effective and less expensive alternative, as its primary mechanism of action is identical to that of the drug, in addition to having many other anti-inflammatory benefits.

Both are zinc ionophores, meaning they shuttle zinc into the cell. There’s compelling evidence to suggest the primary benefit of this protocol comes from the zinc, which effectively inhibits viral replication. The problem is that zinc does not readily enter cells, which is why a zinc ionophore is needed.

You can learn more about all of this in “Is Quercetin a Safer Alternative to Hydroxychloroquine?” “Quercetin Boosts Interferon Response to Viruses and COVID-19” and “How to Improve Zinc Uptake with Quercetin to Boost Immune Health.”

Molecular hydrogen is another simple remedy that could have excellent therapeutic potential against SARS-CoV-2 infection, as explained by Tyler LeBaron in “How Molecular Hydrogen Can Help Your Immune System.”

And please, remember nebulized peroxide. I recently treated the 40-year-old nephew of my gardening consultant that came down with serious pre-terminal COVID-19. He was already on hydroxychloroquine, zinc, quercetin and prednisone and was getting worse until he started the nebulized peroxide. He miraculously improved immediately after this treatment.

I will share his story and video in an upcoming article. The cost of the treatment was less than one penny and it has virtually no side effects if used at the very low 0.1% concentration.

Attacks Heat Up After Second Press Conference

Apparently, the technocrats making the rules disagree with the group’s message of hope and call for return to normalcy, because the attack on America’s Frontline Doctors quickly escalated from scrubbing online platforms of their video to actually taking down their website, americasfrontlinedoctors.com.

In a July 28, 2020, Twitter post, Dr. James Todaro wrote:5

“Wow. It appears Squarespace took down our website today americasfrontlinedoctors.com. We are reaching a new level of censorship. Do people agree with this?”

America's frontline doctors

According to Todaro,6 Squarespace claims the website violated the company’s Acceptable Use policy “regarding activity that’s false, fraudulent, inaccurate or deceiving.” A new website, americasfrontlinedoctorsummit.com7 was created a couple of days later.

Squarespace

But that’s not all. In a July 30, 2020, Twitter post, Gold stated PayPal had temporarily “limited” the group’s ability to receive donations shortly after the new website was announced. However, it seems the problem has been resolved.

That same day, Gold, an emergency room doctor, announced she’d been fired from her job “for appearing in an embarrassing video.” In a Fox News interview with Tucker Carlson, Gold said she’s hired the libel law firm L. Lin Wood to represent her in potential defamation suits, as media efforts are currently underway to smear her professional reputation.

Yale Professor Agrees: Cure for COVID-19 Already Exists

Dr. Harvey A. Risch, a professor of epidemiology at Yale School of Public Health, is also trying to get the message out about hydroxychloroquine. In a July 23, 2020, Newsweek op-ed, he wrote:8

“I have authored over 300 peer-reviewed publications and currently hold senior positions on the editorial boards of several leading journals.

I am usually accustomed to advocating for positions within the mainstream of medicine, so have been flummoxed to find that, in the midst of a crisis, I am fighting for a treatment that the data fully support but which, for reasons having nothing to do with a correct understanding of the science, has been pushed to the sidelines.

As a result, tens of thousands of patients with COVID-19 are dying unnecessarily … I am referring, of course, to the medication hydroxychloroquine.

When this inexpensive oral medication is given very early in the course of illness, before the virus has had time to multiply beyond control, it has shown to be highly effective, especially when given in combination with the antibiotics azithromycin or doxycycline and the nutritional supplement zinc.”

Risch goes on to cite evidence presented in his May 27, 2020, article9 in the American Journal of Epidemiology, which bears the instructive title: "Early Outpatient Treatment of Symptomatic, High-Risk COVID-19 Patients that Should be Ramped-Up Immediately as Key to the Pandemic Crisis."

In it, he reviews five hydroxychloroquine studies that demonstrate “clear-cut and significant benefits to treated patients.” Since the publication of that paper, another seven studies have been published that support hydroxychloroquine’s use against COVID-19. This includes a study led by Dr. Vladimir Zelenko, which involved 400 high-risk COVID-19 patients, all of whom successfully recovered, as well as:10

“… four studies totaling almost 500 high-risk patients treated in nursing homes and clinics across the U.S., with no deaths; a controlled trial of more than 700 high-risk patients in Brazil, with significantly reduced risk of hospitalization and two deaths among 334 patients treated with hydroxychloroquine; and another study of 398 matched patients in France, also with significantly reduced hospitalization risk,” Risch writes.

Hydroxychloroquine Has a Proven Safety Profile

Risch’s American Journal of Epidemiology paper also reviews large-scale studies demonstrating the safety of the medication.

In his Newsweek article,11 he points out that the adverse event reports cited by the U.S. Food and Drug Administration when it warned hydroxychloroquine might cause cardiac arrhythmia, especially when administered with azithromycin, were generated from tens of millions of patient uses of hydroxychloroquine for long periods of time, often for the chronic treatment of lupus or rheumatoid arthritis.

“Even if the true rates of arrhythmia are tenfold higher than those reported, the harms would be minuscule compared to the mortality occurring right now in inadequately treated high-risk COVID-19 patients,” Risch writes.12

“This fact is proven by an Oxford University study of more than 320,000 older patients taking both hydroxychloroquine and azithromycin, who had arrhythmia excess death rates of less than 9/100,000 users … A new paper in the American Journal of Medicine by established cardiologists around the world fully agrees with this.”

Negative Studies Used Toxic Doses

Risch also highlights the fact that all of the studies used to claim hydroxychloroquine is dangerous were actually using toxic doses.

While doctors reporting success with the drug are using standard doses around 200 mg per day for either a few days or maybe a couple of weeks, studies such as the Bill & Melinda Gates-funded13 Recovery Trial used 2,400 mg of hydroxychloroquine during the first 24 hours — three to six times higher than the daily dosage recommended14 — followed by 400 mg every 12 hours for nine more days for a cumulative dose of 9,200 mg over 10 days.

Similarly, the Solidarity Trial,15 led by the World Health Organization, used 2,000 mg on the first day, and a cumulative dose of 8,800 mg over 10 days. These doses are simply too high. More is not necessarily better. Too much, and guess what? You might kill the patient. It’s really unclear as to why these studies used such enormous doses, seeing how the dosages this drug is normally prescribed in, for a range of conditions, never go that high.

Appropriate Dosage Renders Positive Results

Meanwhile, a July 1, 2020, retrospective analysis16,17,18 of 2,541 patients in Michigan found use of hydroxychloroquine alone cut mortality by more than half, from 26.4% to 13.5%. Patients received 400 mg of hydroxychloroquine twice on day 1, followed by 200 mg twice a day for the next four days.

No adverse heart-related events were observed. Hydroxychloroquine in combination with azithromycin had a mortality rate of 20.1%, and azithromycin alone had a mortality rate of 22.4%. The azithromycin was dosed as 500 mg on day 1, followed by 250 mg once a day for the next four days.

According to the authors,19 “The combination of hydroxychloroquine plus azithromycin was reserved for selected patients with severe COVID-19 and with minimal cardiac risk factors.” Unfortunately, zinc was not included in this trial. A majority of doctors using a hydroxycholoroquine regimen do use zinc, plus an antibiotic to stifle secondary bacterial infections.

“Physicians who have been using these medications in the face of widespread skepticism have been truly heroic,” Risch writes.20 “They have done what the science shows is best for their patients, often at great personal risk.

I myself know of two doctors who have saved the lives of hundreds of patients with these medications, but are now fighting state medical boards to save their licenses and reputations. The cases against them are completely without scientific merit …

As all know, the medication has become highly politicized. For many, it is viewed as a marker of political identity, on both sides of the political spectrum. Nobody needs me to remind them that this is not how medicine should proceed.

We must judge this medication strictly on the science. When doctors graduate from medical school, they formally promise to make the health and life of the patient their first consideration, without biases of race, religion, nationality, social standing — or political affiliation. Lives must come first …

Reality demands a clear, scientific eye on the evidence and where it points. For the sake of high-risk patients, for the sake of our parents and grandparents, for the sake of the unemployed, for our economy and for our polity, especially those disproportionally affected, we must start treating immediately.”

Many Countries Have Successfully Quelled COVID-19

If you want to review more studies on hydroxychloroquine, check out c19study.com,21 which at the time of this writing included the following graphic showing the adjusted death toll in countries that adopted the use of hydroxychloroquine early on, compared to those that did or have not.

hydroxychloroquine use

As indicated above, a number of countries have successfully relied on hydroxychloroquine to quell the COVID-19 pandemic, including Dharavi, India, one of the densest slums in the world. As reported by Life Site News:22

“Reports credit the huge turnaround to various factors. Most focused on Dharavi's use of widespread testing and contact tracing … But they ignored the policy most responsible. Indian doctors used hydroxychloroquine (HCQ) for prophylaxis (preventive) treatment — the same drug the American media have politicized.

Dharavi's COVID-19 infection rate dropped drastically from April through June. In July, new infections were very low, almost reaching zero on July 9. Officials have credited23 this turnaround to ‘[a] combination of hydroxychloroquine, vitamin D, and zinc tablets along with homeopathic medicines.’"

In one international poll24,25 of 6,227 doctors in 30 countries, 37% rated the anti-malaria drug hydroxychloroquine as “the most effective therapy” for COVID-19. The poll was done by Sermo, the world’s largest healthcare data collection company and social platform for physicians.

In Spain, where the drug was used by 72% of doctors, it was rated “the most effective therapy” by 75% of them. The typical dose used by a majority of doctors was 400 mg per day.

In the May, 2020, issue of Travel Medicine and Infectious Disease, French microbiologist and infectious disease expert Didier Raoult, founder and director of the research hospital Institut Hospitalo-Universitaire Méditerranée Infection,26 reported27,28 that a combination of hydroxychloroquine and azithromycin, administered immediately upon diagnosis, led to recovery and “virological cure” in 91.7% of patients.

According to Raoult, the drug combination “avoids worsening and clears virus persistence and contagiosity in most cases.” No cardiac toxicity was observed using a dose of 200 mg three times a day for 10 days, along with 500 mg of azithromycin on day 1 followed by 250 mg daily for the next four days.

Chloroquine Inhibits SARS — Known Since 2005

Remarkably, evidence that hydroxychloroquine could be useful against SARS-CoV-2 goes as far back as 2005, when the article29 “Chloroquine Is a Potent Inhibitor of SARS Coronavirus Infection and Spread” was published in the Virology Journal.

Did Dr. Anthony Fauci, appointed to lead the White House Pandemic Response Team, know about this? One could argue he should have. And, if he did, why didn’t he say something? According to this study:30

“… chloroquine has strong antiviral effects on SARS-CoV infection of primate cells. These inhibitory effects are observed when the cells are treated with the drug either before or after exposure to the virus, suggesting both prophylactic and therapeutic advantage.”

In other words, chloroquine functions as both a prophylactic (prevention) and a treatment against SARS coronavirus. This is precisely what many doctors have found with hydroxychloroquine as well, a drug that is very similar to chloroquine but has a safer profile, when used against SARS-CoV-2.

Other early evidence has been highlighted by Raoult. In its April 13, 2020, issue, the German magazine Blauer Bote31,32 lists a collection of 75 expert opinions about the COVID-19 threat. Among them is Raoult, who said (translated from German):

“I did a scientific study on chloroquine and viruses that was published thirteen years ago. Since then, four other studies by other authors have shown that the coronavirus responds to chloroquine. None of this is new.

It takes my breath away that the group of decision-makers doesn't even know about the latest science. We knew about the possible effect of chloroquine on cultured virus samples. It was known to be an effective antiviral.”

A Coordinated Effort to Inhibit Use of an Effective Drug?

The wildly divergent views on hydroxychloroquine appear to have little to do with its safety and effectiveness against COVID-19, and more to do with a concerted and coordinated effort to prevent its use.

There are several reasons for why certain individuals and companies might want to discourage the use of an inexpensive generic drug to work against this pandemic illness.

One of the most obvious reasons is because it might eliminate the need for a vaccine or other antiviral medication currently under development.33 Hundreds of millions of dollars have already been invested, and vaccine makers are hoping for a payday in the billions if not trillions of dollars. In a June 27, 2020, blog post, Dr. Meryl Nass points out:34

“It is remarkable that a series of events taking place over the past three months produced a unified message about hydroxychloroquine … Hydroxychloroquine has been used safely for 65 years in many millions of patients.

And so the message was crafted that the drug is safe for its other uses, but dangerous when used for COVID-19. It doesn’t make sense, but it seems to have worked. Were these acts carefully orchestrated? You decide.

Might these events have been planned to keep the pandemic going? To sell expensive drugs and vaccines to a captive population? Could these acts result in prolonged economic and social hardship, eventually transferring wealth from the middle class to the very rich?”

The fight over hydroxychloroquine may also have political underpinnings, as noted not only by Risch but also by investigative reporter Sharyl Attkisson. In a May 18, 2020, Full Measure report (above), she states that “never before has a discussion about choices of medicine been so laced with political overtones.”

As cautioned by Risch, medicine must not become politicized, especially not during a pandemic. We cannot afford such folly. By politicizing it, the media has taken on a role that can readily be likened to agents of genocide. Naturally, those of us in the holistic field have been aware of how censorship lead people astray, health wise, for a very long time. Conventional doctors are just now getting a taste of what it’s like, and clearly, many are absolutely floored by it.

It’s certainly understandable, because to censor potentially lifesaving medical treatment during a global pandemic really brings it to a whole new level. To so thoroughly demonize a medication that has been used for decades, and could have saved thousands, if not tens of thousands, is as inexcusable as it is inappropriate. Time will tell whether we’ll ever see a time where science is allowed to take its rightful place in medicine again.

Vitamin C has always been vital to immune function, but COVID-19 has shone the spotlight on the vitamin in a big way. While everyone is scurrying to stock up on citrus fruits, there’s actually another fruit that contains more vitamin C than any other: red bell peppers.

Yes, you read that right. Red bell peppers are often categorized, and cooked, as a vegetable, but because they contain seeds, they’re botanically classified as a fruit. Of course, you might not be as concerned with that as much as how they can contribute to your vitamin C intake and what other health benefits red bell peppers have to offer.

Vitamin C in Red Bell Peppers

Although you might immediately think of oranges or orange juice when you hear the term “vitamin C,” bell peppers — specifically sweet red bell peppers — are a far better source.

One cup of sliced raw red bell pepper contains 117 milligrams (mg) of vitamin C,1 which actually exceeds the current RDA for the entire day. For comparison, the same amount of green bell peppers contains around 74 mg.2 According to a comparative study in the September 2012 issue of the Journal of the Science of Food and Agriculture,3 those numbers increase even more if you choose organic bell peppers.

The researchers analyzed the amounts of bioactive compounds in organically grown bell peppers and conventionally grown bell peppers and found that the organically grown peppers contained significantly more vitamin C and higher amounts of carotenoids, like beta carotene, phenolic acids and flavonoids, such as quercetin.

Health Benefits of Red Bell Peppers

Many of the health benefits of red bell peppers can be attributed to the combination of bioactive compounds found within them. A single red bell pepper contains 30 different antioxidants,4 making them one of the most nutrient-dense fruits you can eat.

Antioxidants have been shown to help fight heart disease,5 prevent cancer,6 protect against liver disease and combat oxidative stress and inflammation.7 One of the notable compounds in red bell peppers is quercetin, which is known to have a wide range of health benefits. Quercetin has been shown to help reduce inflammation, alleviate pain,8 lower blood pressure9 and improve learning and memory.10

Of course, some of the health benefits of red bell peppers are also a result of its high vitamin C content. Although vitamin C is often hailed for its powerful immune-boosting properties, it has a protective effect against heart disease and early death, too.

Researchers who published a study in The American Journal of Clinical Nutrition in June 2015 looked at the diet and health of 97,203 people. They found those who consumed the largest amount of fruits and vegetables had a lower risk of developing heart disease and lower risk of early death when compared with those with the lowest intakes.11

The researchers concluded that this benefit may be driven by the high vitamin C concentration in fruits and vegetables, since those with the highest plasma vitamin C levels seemed to experience the greatest effect.

Vitamin C has also been linked to better eye health. Oxidative stress is connected to age-related macular degeneration (AMD) and cataracts, two of the leading causes of blindness in older adults.

In one cohort study published in the Journal of the American Medical Association in December 2005, researchers found that a high intake of vitamin C, combined with an above average intake of beta-carotene, vitamin E and zinc, could reduce the risk of developing AMD by 35%.12

Vitamin C is also heavily involved in your nervous system. It supports your neurons, modulates the transmission of nerve impulses and helps your body make catecholamines13 or the hormones dopamine, norepinephrine and epinephrine that help control your stress levels.

A February 2018 study published in the Journal of Critical Care found preliminary evidence that administering vitamin C in addition to standard therapy may help combat inflammation and stabilize heart rate in those with sepsis and septic shock14 — an emergency situation that accounts for 30% to 50% of all in-hospital deaths15 and believed to be the underlying cause of some serious complications and death in severe COVID-19 infections. Vitamin C may also be useful for16:

Protecting against UV damage

Preventing wrinkles and loss of collagen

Healing burns and wounds

Reducing acne

Alleviating dry skin

Antiaging17

How Much Vitamin C Do You Need?

Vitamin C is water-soluble, which means it dissolves in water and is carried throughout the body to your cells for immediate use. Your cells take what they need and anything left over gets excreted from your body through your urine. Unlike fat-soluble vitamins, your body doesn’t store any extra for later. Your body also can’t make vitamin C on its own. That means it’s extra important that you get sufficient amounts from your diet every day.

The current recommendation for vitamin C is 75 mg per day for adult women and 90 mg per day for adult men.18 While daily doses of several hundred mg per day makes sense for many, there’s evidence that higher doses, meaning those over 1,000 mg per day, may be better for combating viruses like the common cold19 and Epstein-Barr20 and as part of the treatment for cancer.21

Other Sources of Vitamin C

One cup of sliced red bell peppers provides more than the current RDA for vitamin C, but if you want to increase your intake even more, there are plenty of other fruits and vegetables that are excellent sources of vitamin C as well.

One of the most vitamin C-rich fruits available is the acerola or Barbados cherry,22 which provides 1,644 mg of vitamin C per cup.23 Compare that to a medium orange, which contains about 69.7 mg of vitamin C.24 Other fruits and vegetables that are particularly rich in the vitamin include25:

Broccoli

Sweet potato

Grapefruit

Tomato

Cauliflower

Kale

Chili peppers

Papaya

Cantaloupe

Brussels sprouts

Tomato/tomato juice

Kiwifruit

Artichoke

Strawberries

Cooked cabbage

Vitamin C Supplements

Supplementation is an option too, but it’s best to get what you need from a variety of fruits and vegetables. When you eat fruits and vegetables, you’re not only getting natural, easily absorbed vitamin C, you’re also getting dozens of other super nutrients, like antioxidants and phytochemicals, which help fight chronic disease, reduce inflammation and help eliminate carcinogens.

However, if you’re having trouble meeting your needs with diet alone, you can supplement a healthy diet with liposomal vitamin C, which has enhanced bioavailability when compared to other oral forms of the vitamin.

In one small study published in Nutrition and Metabolic Insights in June 2016, researchers compared liposomal vitamin C supplements to other types of oral vitamin C,26 finding liposomal supplements raised the amount of vitamin C in the blood more effectively than the other unencapsulated types.

That’s because the liposomes encapsulate, or surround, the vitamin C, which protects it from the harsh environment of your digestive tract, according to a July 2019 report in the Journal of Liposome Research.27 This helps slows down the release of the vitamin from the supplement and improves absorption.

Researchers found that patients with COVID-19 presented with abnormal liver tests at much higher rates than suggested by earlier studies. They also discovered that higher levels of liver enzymes -- proteins released when the liver is damaged -- were associated with poorer outcomes for these patients, including ICU admission, mechanical ventilation, and death.

A new study warns that even with some lockdown measures staying in place to the end of 2021, without more structural interventions global temperatures will only be roughly 0.01°C lower than expected by 2030. However, the study estimates that including climate policy measures as part of an economic recovery plan with strong green stimulus could prevent more than half of additional warming expected by 2050 under current policies.

Ticks and mosquitoes don’t care about COVID-19 safety protocols. They don’t care that people are trying to squeeze out the last moments of this restrictive summer by getting outdoors, hiking, or just sitting on their decks at night and feeling something that’s close to normal.

COVID-19 has commanded our attention and caused people to adapt their behaviors to prevent one major health concern, but it doesn’t mean others have been eliminated. “Masks and social distancing will do nothing to protect you from what ticks and mosquitoes potentially carry,” says Dr. Todd Ellerin, director of infectious diseases and vice chairman of the department of medicine at South Shore Hospital in Weymouth, Massachusetts, and an instructor in medicine at Harvard Medical School.

Ellerin adds another reason to remain vigilant: tick-borne illnesses and COVID-19 share symptoms, such as fevers, achiness, fatigue, sore throats, rashes, headaches, low white blood cell counts, and elevated liver functions. One illness can be confused for the other, and health care resources are used up in the process. “It adds another level of diagnostic confusion,” he says. It means taking the necessary precautions becomes more important now, but the upside is one repellent is effective for both insects.

What are some common tick- and mosquito-borne illnesses?

This list isn’t exhaustive, but common viruses associated with ticks include Lyme disease, anaplasmosis, and babesiosis. They all can occur nationwide, but the highest concentrations are in the northeast and Midwest. Borrelia miyamotoi is relatively new and rare, according to the Centers for Disease Control and Prevention, so questions about where it’s most prevalent are still being explored. And with Rocky Mountain spotted fever, over 50% of cases come from five states in the southeast and Midwest.

Common mosquito viruses include malaria, Zika, West Nile, and Eastern equine encephalitis (EEE). The CDC calls EEE rare, but Ellerin says that last year there was a spike. Massachusetts, for example, had 12 cases after reporting none from 2014 to 2018. The concern with EEE is that the virus usually runs in two-to-three-year cycles, and approximately 30% of people who become infected will die from it; that’s why mosquitoes shouldn’t be ignored. “Globally, mosquitoes actually are the most dangerous animal, causing the most deaths,” says Ellerin.

Bug spray is a safe and effective prevention strategy

Taken all together, the risks of contracting a serious illness from a tick or mosquito can seem overwhelming. However, it may be reassuring to know that over-the-counter bug sprays work well to repel ticks and mosquitoes through one of three common active ingredients: oil of lemon-eucalyptus, picaridin, or diethyltoluamide, better known as DEET. Permethrin is another one, but it’s an insecticide and is designed to be used on clothing, not skin. Ellerin says that whichever bug spray ingredients you choose, they’re safe and effective when used according to their labels.

Find the repellent that’s right for you

The choice may just come down to preference or need. DEET is the most well-known, but it can cause irritation, says Dr. Abigail Waldman, clinical director of the Mohs and Dermatologic Surgery Center at Brigham and Women’s Hospital, and assistant professor at Harvard Medical School. If that’s the case, picaridin is best for sensitive skin. Some people may prefer not to use a chemical, so oil of lemon-eucalyptus is a good option. There are two caveats, she says. It’s not recommended for children under 3 years old, and a botanical can still cause a rash; for that, after you wash with soap and water, apply an emollient, such as Vaseline or Aquaphor.

No matter what type of bug spray you choose, the concentration of the active ingredient that repels ticks and mosquitoes is important. Waldman says with DEET, you want at least 20%, but no more than 50%. With picaridin, it’s 5% to 20%. And with oil of lemon-eucalyptus, a 10% to 30% concentration is most effective.

How to safely use it

Pay attention to how you apply bug spray. Cover all exposed skin; don’t forget your head, Waldman says. For your face, spray it onto your hands first and then apply. Ellerin adds to spray your ankles and tops of shoes for low-lying ticks. And as a further means of prevention, it helps to walk on clear paths, avoiding tall grass where ticks like to reside. Wear clothes that cover your extremities and tuck pant legs into your socks. At home, mow your lawn frequently, clear away brush, and keep play areas away from shrubs, bushes, and wooded areas.

Waldman says that each parent knows the abilities of their kids, but young children shouldn’t handle bug spray on their own. The concern is that it would go into eyes, noses, ears, or mouths, and that young children tend to put their fingers in their mouths. At high exposure it can be toxic, so it’s good to avoid ingesting it at any level, and it’s a good idea for everyone to wash their hands after putting on repellent, she says.

If you’re planning to be in the sun, apply sunscreen first since it needs to sink in, then bug spray, and reapply sunscreen every 60 to 90 minutes since the repellent reduces effectiveness. As for the repellent, it usually lasts six to eight hours. If it hasn’t worn off by bedtime, you’ll want to wash it off with soap and water, as it can be irritating if left on overnight. Unless you are camping overnight in an area with ticks or mosquitoes, you don’t want it sitting on your skin if insects aren’t a concern. “If you don’t need it on, get it off,” Waldman says.
