New Guidance on COVID-19 Can Be Confusing

Sometimes it seems as though we need a spreadsheet to keep track of all the changing information and recommendations on COVID-19.

  • Masks/no masks?
  • Boosters? Maybe not, maybe now, maybe later.
  • Quarantine? Yes, no, who, and how long?

Our primary care concierge doctors in Jupiter don’t mean to criticize the researchers and public officials who are responsible for keeping us healthy. The SARS-CoV-2 coronavirus is, after all, a disease we’d never seen until early in 2019. No one knew how to deal with it.

And thanks to the combined efforts of scientists around the world, we’ve made tremendous strides in the effort to combat it.

But one thing few counted on was “pandemic fatigue,” which meant many people rapidly grew tired of taking precautions and radically altering their lifestyles to help stem the spread of COVID-19.

Which may be what’s behind the latest guidance from the Centers for Disease Control and Prevention (CDC). (https://www.cdc.gov/media/releases/2022/p0811-covid-guidance.html) 

A new approach

This month the CDC relaxed many of its coronavirus recommendations, leaving measures to battle to limit viral spread largely up to individuals.

According to The Washington Post:

  • “No longer do schools and other institutions need to screen apparently healthy students and employees as a matter of course.
  • “The agency is putting less emphasis on social distancing—and the new guidance has dropped the ‘six-foot’ standard.
  • “The agency’s focus now is on highly vulnerable populations and how to protect them—not on the vast majority of people who at this point have some immunity against the virus and are unlikely to become severely ill.”

In releasing the new guidance, the CDC cited improved tools like vaccination, boosters, and treatments to better protect ourselves from the virus.

“We also have a better understanding of how to protect people from being exposed to the virus, like wearing high-quality masks, testing, and improved ventilation,” Greta Massetti, a CDC epidemiologist, said in a statement.

“This guidance acknowledges that the pandemic is not over, but also helps us move to a point where COVID-19 no longer severely disrupts our daily lives,” she added.

Isolation changes

In one fairly substantial shift, for example, the CDC no longer recommends quarantine if you’re up to date with your vaccines and have been exposed to COVID-19. Instead, you should mask for 10 days and get tested on Day Five.

Additional CDC guidance on isolation includes the following:

  • If you’ve tested positive and have a healthy immune system, regardless of your vaccination status, you should isolate yourself for five days. On Day Six, you can end isolation if you no longer have symptoms or have not had a fever for 24 hours and your symptoms have improved.
  • Once isolation has ended, you should wear a high-quality mask through Day 10. If you test negative on two rapid antigen tests, however, you can stop wearing your mask sooner.
  • Until Day 11 at least, you should avoid visiting or being around anyone who is more likely to have severe outcomes from COVID-19, including the elderly and people with weakened immune systems.

These changes stem from a new statistic, according to Massetti: 95 percent of the U.S. population has at least some level of immunity against the virus, either from vaccination or previous infection.

What about boosters?

As for booster shots, the U.S. Food and Drug Administration (FDA) finally decided last month against allowing adults younger than 50 to become eligible for a second booster vaccine (for a total of four mRNA shots).

Currently, only those age 50 and older and children at least 12 years old with impaired immune systems can get a second booster.

This is because the agency expects to have reformulated mRNA boosters available by next month that will contain components from both the original virus and its variants, as well as from the currently circulating (and highly contagious) omicron subvariants BA.4 and BA.5.

Meanwhile, the FDA still recommends that anyone under age 50 receive a single booster shot, and people older than 50 or those with weakened immune systems receive a second mRNA booster.

The mask question

No one likes wearing masks, especially in the heat. However, our primary care concierge doctors believe it’s better to err on the side of caution, especially if you’re immunocompromised or older than 65.

Especially given the new CDC guidance revisions, there’s no harm in wearing a mask in crowded indoor situations with poor ventilation.

It’s true that we now have effective treatments for COVID-19, but given the risk of long COVID—one recent study found that as many as one in every eight people who contracted it had lingering symptoms—what’s the point in taking unnecessary chances?

It’s up to you, of course, but in a recent interview with The Post, Ziyad Al-Aly, an epidemiologist at Washington University in St. Louis, compared the current state of the country to “the Wild West.”

“There are no public health measures at all,” he told the paper.

“We’re in a very peculiar spot, where the risk is vivid and it’s out there, but we’ve let our guard down and we’ve chosen, deliberately, to expose ourselves and make ourselves vulnerable.”

How to Combat the Lingering Danger of ‘Forever Chemicals’

Disease, Environment, Health Basics, Healthy Living, Lifestyle, Nutrition, Preventative Health

They’re called “forever chemicals” because they don’t break down fully in the environment, and this summer the Environmental Protection Agency (EPA) warned that they are more dangerous to human health than regulators knew.

Within weeks, the National Academies of Sciences, Engineering, and Medicine (NAS) weighed in with its own 300-page report on these chemicals, known as perfluoroalkyl and poly-fluoroalkyl (PFAS) substances, urging doctors to test high-risk patients for PFAS contamination.

Because of the heightened attention on these chemicals, our primary care concierge doctors in Jupiter want to summarize for you what we’ve learned about them, and offer tips on how to reduce your exposure.

The Problems with PFAS

In 1946, DuPont introduced its revolutionary non-stick product, Teflon. By 1950, studies by DuPont and 3M showed that PFAS could build up in the blood, but chose to keep these results secret, according to the non-profit Environmental Working Group (EWG).

Since 1998, when a class-action lawsuit against a West Virginia DuPont factory revealed the extent of the pollution from the factory, researchers have found probable links to such diseases as:

  • thyroid disease
  • high blood pressure
  • kidney cancer
  • testicular cancer
  • breast cancer
  • higher cholesterol levels
  • ulcerative colitis
  • weakened immune system 
  • vaccine interference
  • weight gain
  • changes in liver enzymes
  • decreased fertility
  • growth and learning delays in infants and children

The NAS report encourages doctors to conduct blood tests for these chemicals on patients who are worried about exposure or who are at high risk for exposure or who are in “vulnerable life stages”: during pregnancy, early childhood, and old age. 

They’re Everywhere

As we’ve seen with microplastics, PFAS can begin innocently enough and end up in unexpected places, including our water.

Recently, for example, Consumer Reports (CR) tested more than 100 food-packaging products from U.S. restaurants and supermarkets. They found dangerous PFAS chemicals in many of the products, including paper bags for french fries, hamburger wrappers, pizza boxes, molded fiber salad bowls, and single-use paper plates.

These chemicals are used in a wide variety of products, including waterproof and sweatproof makeup, nonstick cookware, cellphones, waterproof clothing, carpets, and—especially—fast-food containers, where their ability to make products grease-proof has led to their widespread use.

They are also used to make products water-repellent and resistant to high temperatures, as well as in fire-fighting foams used at military installations, floor wax, upholstery, and clothing. The qualities that make items containing PFAS so desirable, however, also make them long-lasting in the environment.

Lingering Threat

“These chemicals are ubiquitous in the American environment,” Ned Calonge, an associate professor of epidemiology at the Colorado School of Public Health and chair of the NAS committee that wrote the report, told CNN.

“More than 2,800 communities in the U.S., including all 50 states and two territories, have documented PFAS contamination,” he said.

Researchers have even detected them in the snows of Mt. Everest, apparently shed from climbers’ waterproof tents and parkas. 

“You are not just exposed in one place or one source,” toxicologist Linda Birnbaum, former director of the National Institute of Environmental Health Sciences and the National Toxicology Program, told The Washington Post. “They are everywhere.”

The problem is that these chemicals build up (or “bioaccumulate”) in the body over time. 

And according to the Centers for Disease Control and Prevention (CDC), which has been conducting studies of the U.S. population, PFAS has been found in the blood of nearly all people they’ve tested. Since the risk appears to rise with the amount of exposure, it’s important to try to limit the amount we come in contact with.

What You Can Do

Because PFAS chemicals are found in so many consumer products, they’re next to impossible to avoid. But there are ways to reduce the amount you’re exposed to.

“The most dangerous way that people are exposed to PFAS is through drinking water,” says Don Huber, director of product safety at CR.

That’s why the NAS report recommended filtering tap water as a major step consumers could take to protect themselves.

“The water filters that are most effective for PFAS are reverse osmosis filters,” David Andrews, a senior scientist for the EWG, told CNN, adding that some carbon-based filters can also reduce some levels.

“The important part is that you have to keep changing those filters,” he said. “If you don’t change that filter, and it becomes saturated, the levels of PFAS in the filtered water can actually be above levels in the tap water.”

The NAS committee also offered these tips:

  • Stay away from stain-resistant carpets and upholstery, and don’t use waterproofing sprays.
  • Look for the ingredient PTFE or other “floro” ingredients on product labels.
  • Avoid nonstick cookware. Instead, use cast-iron, stainless steel, glass, or enamel products.
  • Boycott takeout containers and other food packaging. Instead, cook at home and eat more fresh foods.
  • Don’t eat microwave popcorn or greasy foods wrapped in paper.
  • Choose uncoated nylon or silk dental floss or one that is coated in natural wax.

Why Monkeypox Is Not Like COVID-19

COVID, Disease, Lifestyle, News, Uncategorized, Vaccinations

Last month, the World Health Organization (WHO) declared the newly spreading monkeypox virus a global health emergency.

This has prompted many to fear we’re heading into another coronavirus situation, as our concierge primary care doctors in Jupiter have found from talking with our patients.

While this is a debilitating, painful, and—occasionally—deadly virus, there are many reasons why it’s very dissimilar to the SARS-CoV-2 virus, the virus that causes COVID-19.

The history is different

Although both originated as “zoonotic” diseases—that it, they began in animals and spread to humans—we have a far longer history with monkeypox, meaning we know more about it than we did when the coronavirus first appeared.

According to the Centers for Disease Control and Prevention (CDC), monkeypox was first discovered in 1958 when two outbreaks of a pox-like disease occurred in colonies of monkeys kept for research, thereby giving the disease the name “monkeypox.” Its typical animal hosts, however, are rodents and other small mammals.

The first human case of monkeypox was recorded in 1970 in the Democratic Republic of Congo during a period of intensified effort to eliminate smallpox. Since then, monkeypox has been reported in humans in other central and western African countries.

Although relatively new to the U.S., a large monkeypox outbreak occurred here in 2003 as a result of imported rodents.

Transmission is different

Next, the ways the two viruses are transmitted are completely different.

Unlike the largely airborne transmission of SARS-CoV-2 through aerosols that linger in the air, the monkeypox virus can only be spread through close contact with an infected person or animal, or materials such as bedding or towels that are contaminated with the virus.

In addition, monkeypox appears to be far less transmissible than COVID-19. One study found that just three percent of those in close contact with an infected person would develop monkeypox.

It appears at this time to be spreading primarily among gay and bisexual men following sexual encounters, but anyone who comes into close and prolonged, direct contact with the pox sores can become infected.

Even women, and at least two children, have been reported to have contracted monkeypox, as a result of being in close proximity to men who have sex with other men.

The symptoms are different

Unlike the stealth infections of the coronavirus, it’s very apparent when a person is infected with monkeypox. As with COVID-19 and other viruses, they develop fever, headache or body aches, chills, muscle aches, and exhaustion.

These symptoms are also similar to those of smallpox, a cousin of monkeypox, with one difference:

“A feature that distinguishes infection with monkeypox from that of smallpox is the development of swollen lymph nodes,” the CDC says.

Otherwise, however, both smallpox and monkeypox exhibit the same signature fluid-filled lesions (the so-called “pox”), which the coronavirus doesn’t produce. Some individuals have these sores all over the body, while others may have only a single lesion. This rash can be extremely painful.

The vaccines are different

When COVID-19 first appeared two-and-a-half years ago, it was a brand new virus (i.e., “novel” coronavirus).

We knew nothing about it, and at the time had no way to combat it in the form of either effective treatments or vaccines.

Because of our long history with monkeypox, however, we do have vaccines and antiviral treatments. Monkeypox and smallpox come from the same family of viruses (although monkeypox is not as severe as smallpox). That has allowed us to utilize the stockpile of smallpox vaccines and antivirals to fight monkeypox.

And, unlike the coronavirus vaccines, the vaccines for monkeypox are effective even after infection, if given within four days of exposure. Even if the vaccine is given as late as two weeks after exposure, it can still lessen the likelihood of severe illness.

Not to worry?

Does all this mean we don’t have to panic about monkeypox? Panic is never a good idea because it prevents thoughtful responses in a crisis. But at this time the monkeypox outbreak still appears to be confined largely to men who have sex with men and those who are closest to them and who may come in contact with the open sore or infected linens.

If you fall into one of those categories, it’s important to take precautions until the supply of vaccines and antivirals becomes sufficient to cover everyone at high risk of exposure, because cases are spreading rapidly in the U.S. At the end of July, the Centers for Disease Control and Prevention (CDC) reported more than 3,500 confirmed cases but noted that is probably a significant undercount.

Experts advise that, if you’re at risk, you temporarily reduce your number of sexual partners, reconsider sex with new partners, and exchange contact details with any new partners to enable follow-up, if necessary.

Infected people are encouraged to self-isolate from other humans as well as pets, and to wear a mask and long clothing over any sores.

Although there is currently a limited supply of vaccines in the U.S., the government has purchased 2.5 million doses, which should be available in the coming weeks. This means it isn’t yet enough available to offer shots to all high-risk individuals.

So until there is, take precautions, and let us know if you think your symptoms might be those of monkeypox. It’s a painful, debilitating, and sometimes deadly disease, but we can treat it if it’s caught in time.

The post-COVID syndrome commonly known as “long COVID” or “long-haul COVID” can be debilitating.

Although not everyone experiences aftereffects from infection, some of the most common symptoms include lingering fatigue, shortness of breath after even mild exertion, trouble sleeping, “brain fog,” and symptoms that worsen after physical or mental activity. Others can include rapid heartbeat, chronic pain, dizziness, muscle weakness, and erectile dysfunction.

Dr. Anthony Fauci’s comment that we are “certainly, right now, in this country, out of the pandemic phase” of COVID-19 sparked numerous questions to our primary care concierge doctors in Jupiter.

It also seemed to cause a great deal of confusion and misconceptions around the country at large, at least until he clarified his statement the following day.
