WARNING: COVID-19 IS NOT OVER!

Rip off your mask! Run, don't walk to your favorite bar, restaurant or neighbor's raucous indoor party! Hug the persons you love, even the complete strangers you meet on the street! Go shopping again, in person, in a real store with crowds pushing and shoving you in a scene reminiscent of my childhood days during a sale at Filene's Basement, Boston's notoriously cheap haven in the days of yore before Amazon conquered all things good. Go back to the offices we used to hate going back to! We can finally return to normal, whatever that means and not have to grab a calculator to determine the risk/benefit ratio of every activity we engage in during our waking hours from greeting our mailman to picking up a pizza or even eating it, heaven forbid, inside the pizzeria.

Hold it! Not so fast, my friends. Despite the lifting of most mandates by Governors and local politicians (and reinterpreting their recommendations, as only the CDC, master of "government speak" can do best), it is not a time to completely let down our guard. Let's look at the numbers. As of this writing, approximately 100,000 Americans are newly diagnosed with Covid-19 EVERY DAY while almost 2,000 of us are still dying from this dreadful disease every single day. Unless that statistic changes, we would lose almost 3/4 million Americans a year from Covid-19. To put that in perspective, according to the CDC, between 12-52,000 Americans die every year from the flu. And, while we have made tremendous gains in our vaccination rates, still about 1/3 of our eligible population remains to be vaccinated at all...think about it...that's over 100 million Americans who are still not, and likely to never get vaccinated. And, if you want to think about this from a global citizen's point of view, only 63% of the world's population has received at least one dose of a Covid-19 vaccine. And that statistic drops to a shocking 12.9% of people in low-income countries having received at least one dose.

And, before we celebrate too wildly about the supposed retreat of Covid-19 from a frightening pandemic to a manageable endemic, let's not forget that only three months ago, Omicron was only known to American mathematicians as a Greek letter. Since December 1, when it came to us from South Africa, it spread throughout the U.S. faster than a California wildfire gone awry, infecting both the vaccinated (even many with booster shots) and the unvaccinated, although with more serious effects in the latter group. Any respectable epidemiologist or infectious disease expert will tell us that, given that about 40% of the world's population is still unvaccinated, representing over 3 billion people, there is a lot of room for the next variant...and make no mistake, there will be a next varant...to spread and grow, possibly with even more capability than Omicron, to dodge our current vaccination protocols. 

In short, until the world achieves immunity from vaccination (or sadly, infection), we still need to keep our guard up, at least somewhat, depending upon the infection rates and vaccination rates in our neighborhood, village, county, state and country (since many of us can't wait to start traveling again, hoping we don't expire before our miles). I can't and won't tell you what to do with your life and the risk calculations you may still be calculating. I can only tell you what I am doing, which is keeping my mask on in most indoor settings, especially when crowds are likely present (e.g., supermarkets, museums, movies, theatres, clubs, synagogues, etc.). I am also, as we move into Spring and Summer, going to do most of my restaurant dining outdoors. For me, these simple precautions will make me feel safer and, hopefully, keep me and those around me safer not just from Covid-19, but from the common cold and flu, neither of which have struck me in the 2 years that I have been masking up.

A Grim Milestone for American Public Health We are facing a public health emergency that was entirely preventable. According to updated data from the Centers for Disease Control and Prevention (CDC), the United States has recorded 2,170 confirmed measles cases in 2026—and we are only halfway through the year. This staggering figure nearly matches the 2,289 cases recorded across the entirety of 2025, representing a measles crisis on a scale this country has not seen in over three decades. Measles was declared officially eliminated from the United States in 2000, thanks to robust and widespread uptake of the Measles, Mumps, and Rubella (MMR) vaccine. Today, that monumental achievement is on the verge of being permanently erased.

For decades, Americans have relied on warning labels to alert consumers to hidden dangers. Cigarette packages warn of cancer. Alcohol labels caution pregnant women. Medications disclose side effects. Yet one of the most powerful and potentially addictive products used by millions of children every day carries virtually no warning at all: social media. In 2024, as I wrote in the September, 2024 issue of this newsletter, then-U.S. Surgeon General Dr. Vivek Murthy called on Congress to require cigarette-style warning labels on social media platforms, arguing that parents and children deserve to know that excessive use has been linked to anxiety, depression, body image problems, sleep disruption, and other mental health concerns. He stated that social media had become an important contributor to the youth mental health crisis and that warning labels could help increase awareness among families. Unfortunately, that proposal has stalled under the new administration. The opportunity to provide parents with basic health information appears to have been abandoned just as evidence of social media's harmful effects continues to mount.

Artificial intelligence (AI) is rapidly reshaping the landscape of healthcare, particularly in the realm of medical diagnosis. From analyzing medical images to predicting disease risk, AI-driven tools are increasingly being integrated into clinical workflows. While the potential benefits are substantial—improved accuracy, faster diagnoses, and expanded access to care—there are also meaningful risks that warrant careful scrutiny. Understanding both sides is essential for clinicians, policymakers, and patients alike.

Lithium-ion batteries power much of modern life. From smartphones and laptops to e-bikes, power tools, and even home energy storage systems, these compact and efficient batteries are everywhere. But as their use has expanded, so too has a serious and often underestimated danger: the risk of fire. Lithium-ion battery fires are not like typical household fires. They burn hotter, spread faster, and can reignite even after appearing to be extinguished. These fires are caused by a process known as “thermal runaway,” where damage, overheating, or internal defects trigger a chain reaction inside the battery. Once this process begins, it can release flammable gases, cause explosions, and produce intense flames that are difficult to control.

1. Weakening National Drinking Water Standards  In April 2024, the EPA finalized the first federally enforceable National Primary Drinking Water Rule (NPDWR) for six PFAS, including PFOA, PFOS, PFHxS, PFNA, HFPO-DA (GenX), PFBS, and mixtures of these chemicals. These rules established maximum contaminant levels (MCLs) and required monitoring and treatment timelines for public water systems. Under Trump's EPA, this landmark public health rule is being undone :

Winter in the Northern Hemisphere brings cold weather, snow, and often severe storms. These conditions can lead to power outages that last hours or even days. When electricity is lost and temperatures plummet, many households turn to alternative heating methods or portable power generators. While these actions are understandable, they can expose families to a perilous and often invisible threat: carbon monoxide (CO) poisoning .

As Thanksgiving approaches, kitchens across the country are about to come alive with the sounds and smells of holiday cooking. While this season brings family, gratitude, and plenty of delicious food, it also comes with a serious and often overlooked risk: foodborne illness. In the U.S., Salmonella and Listeria remain two of the most dangerous and persistent causes of food poisoning—especially during the holidays, when increased food preparation, crowded refrigerators, and large holiday meals create ideal conditions for bacterial growth.Whether you’re hosting your first Thanksgiving dinner or you’re a seasoned holiday chef, brushing up on a few key food safety practices can help you keep your loved ones healthy and your celebration memorable for all the right reasons.

The race to develop autonomous vehicles (AVs) has reached a pivotal moment. Alphabet-owned Waymo, widely regarded as the frontrunner in the field, has rolled out fully driverless taxis in Phoenix, San Francisco, and Los Angeles, with plans to expand to additional cities. But as more Waymo vehicles hit public roads without human drivers, the question looms large: Are they truly safer than the people they’re replacing behind the wheel?

We are now in the middle of another football season, and the question, as asked every year: Is this sport safe enough for our high school, college, and professional athletes to play? Football has always been a violent sport of collision, glory, and growing concern. Over the last decade, research tying repetitive head impacts to chronic traumatic encephalopathy (CTE) has shaken parents, players, and the game’s governing bodies. The central realities are straightforward but sobering: repeated head impacts — both diagnosed concussions and the many “sub-concussive” blows players take — are linked to later-life brain pathology; helmets and add-ons can lower impact forces, but no helmet or cover has been shown to prevent CTE; and rule and culture changes that reduce the number and severity of head impacts are where the biggest gains lie.

The Centers for Disease Control and Prevention (CDC) has long been viewed as the nation’s front-line defense against disease outbreaks, health emergencies, and public health threats. But today, the agency faces internal turmoil, political interference, and organizational confusion that experts warn could have dangerous consequences for the U.S. healthcare system—and for ordinary Americans.
