- [Clean Air Is Non-Negotiable: A Call for Measurable Solutions](https://publichealthactionnetwork.org/clean-air-is-non-negotiable-a-call-for-measurable-solutions/): Breathing indoors should not be a health risk. For more than a century, public health transformed society by making clean water non-negotiable. We built systems. We tested them. We regulated them. We improved them. No one debates whether water safety is optional. Indoor air should carry the same weight. Clean air is not a luxury. It is a basic condition of human dignity. Respiratory pathogens like COVID-19, influenza, RSV, and future airborne threats have exposed something uncomfortable: we do not actually measure or enforce air performance in most of the places where we spend our lives. We have guidance (which […]
- [Keith Muise: Crossing Canada in Times of COVID, Part 3](https://publichealthactionnetwork.org/keith-muise-crossing-canada-in-times-of-covid-part-3/): As I made my way across the country, I survived on bananas, Ritz Crackers, and Nutri Grain bars. At every gas station I wore a pair of rubber gloves to avoid touching the gas nozzle, and I made sure to throw away all of my garbage at every stop. City to city, I breezed through, like a ghost, among the people but never really there. Since the only people I spoke to were hotel workers, I doubt I left much of an impression on anyone I encountered. As far as the universe was concerned, I was never really in any […]
- [Keith Muise: Crossing Canada in Times of COVID, Part 2](https://publichealthactionnetwork.org/keith-muise-crossing-canada-in-times-of-covid-part-2/): As I drove through the city, memories of our life there played out like a Netflix documentary, and I was met with a relieving sadness as I got closer and closer to the edge of the city.  We had spent almost as much time there as we did in our hometown, we had seen the city burn in 2016 and then rise from the ashes, our son was born there, we had dozens of friends, and even some family there, and as I passed the city limits, I began laughing uncontrollably because at that moment I knew if I started […]
- [Keith Muise: Crossing Canada in Times of COVID, Part 1](https://publichealthactionnetwork.org/keith-muise-crossing-canada-in-times-of-covid-part-1/): I had driven across Canada once before, ten years earlier to get married in my home province of Newfoundland and Labrador, but I knew this time was going to be different. This time we were smack dab in the middle of a global pandemic, and I was going to be taking the trip alone.  Last time I made the trip I had my little brother with me and we turned the trip into an adventure, and let’s face it there was no way in 2010 that I was going to make it to Newfoundland from Alberta, I didn’t even own […]
- [What a year! Looking back and looking forward, from PHAN CEO Tarz Ludwigsen](https://publichealthactionnetwork.org/what-a-year-looking-back-and-looking-forward-from-phan-ceo-tarz-ludwigsen/): When Public Health Action Network (PHAN) was founded in late 2024, it emerged from a shared conviction among a group of practitioners, researchers, and technologists that public health needed a stronger voice and a more connected approach to action. We were founded by individuals with deep experience across data analysis, research and development, statistics, innovation, public health practice, and identification of emerging needs. We have seen what happens when data is ignored, when research fails to translate into action, and when public health decisions are made without the benefit of coordinated insight. PHAN was created to change that, with an […]

- [Nancy's Vaccine Story](https://publichealthactionnetwork.org/nancys-vaccine-story/): A guest post from PHAN supporter Nancy Park, Chico, CA The year was 1955. I was 13 months old and my mother was feeding me on a spring morning while watching “The Today Show” on a black and white television with a tiny screen. Big news was announced – Dr. Jonas Salk’s vaccine against polio had been found to be effective and safe. It soon would be available to the public. My mother, a public heath nurse, broke down and wept. This development meant I would be spared the ravages of polio, because she knew that vaccines work. As a […]

- [Statement on the Current Trajectory of U.S. Public Health Policy](https://publichealthactionnetwork.org/statement-on-the-current-trajectory-of-u-s-public-health-policy/): We at PHAN are very disheartened at the current situation in U.S. public health policy and infrastructure. We believe the current approach to how public health is being handled in the U.S. and globally is heading in the wrong direction for humanity, in a manner that will damage us for generations. We’re seeing a vast increase in distrust and disinformation spread about airborne pathogens, pharmaceutical interventions like vaccines, and non-pharmaceutical interventions like masks and air purification that are moving us backward in time. The U.S. has historically been a leader in public health. The loss of our credibility, public health […]
- [A Call for Openness in an Age of Obfuscation: Reinforcing Trust, Health, and the Environment](https://publichealthactionnetwork.org/a-call-for-openness-in-an-age-of-obfuscation-reinforcing-trust-health-and-the-environment/): Having been in tech in a variety of roles and industries for over 30 years there are a few constants that have emerged irrespective of the industry, and only a few I’ve seen shape the landscape for the better – one of those constants being open source technologies. From helping establish very early standards like OBI (Open Buying on the Internet), to launching full-scale projects quickly and securely developing and using open source CMS platforms, I’ve watched and helped firsthand how community-built tools not just level the playing field, but play an integral role in evolving better solutions. Open source […]
- [Using AI/LLMs to help guide you through your health conditions](https://publichealthactionnetwork.org/using-ai-llms-to-help-guide-you-through-your-health-conditions/): August 8th, 2025 You may be surprised (or maybe not!) to hear that many folks are using AI/LLM (artificial intelligence/large language model) applications for their healthcare issues. They’re using it to help figure out whether their symptoms might be due to COVID or Long COVID, to suggest procedures and lab tests to help rule in or rule out various illnesses, and to suggest verbiage to use with healthcare providers. In this post I’ll generally refer only to ChatGPT since that’s the most commonly used one. Several other AI/LLMs exist including Gemini and Claude. They may have differences in the language […]
- [Can’t mask all the time but still want to protect yourself and others?](https://publichealthactionnetwork.org/cant-mask-all-the-time-but-still-want-to-protect-yourself-and-others/): July 29th, 2025 We at PHAN strongly recommend that everyone mask when they’re in public indoor spaces, outdoor spaces that are very crowded, or private spaces where other folks are present who have not been practicing mitigations. But we know it’s not always practical or feasible to mask in all of those situations. If you have to limit your masking, we recommend focusing on three places that will make the most difference for you and for other people, especially others who are immuno-compromised: People who are immuno-compromised tend to avoid going out to places they don’t have to. They also […]

- [Long COVID from a partner's perspective: Ian & Dani's Story](https://publichealthactionnetwork.org/long-covid-from-a-partners-perspective-ian-danis-story/): Long COVID is a devastating enough syndrome by itself but combined with other chronic conditions, it can be extraordinarily difficult to treat, and the effects of Long COVID on family members can be extremely challenging. PHAN founder Ian Goodfellow and his wife Dani have experienced all of it. Ian had Menier’s Syndrome for most of his life, but he was able to accommodate it and lived an active life with mountain biking, hiking, and working full time as the head of Google Brain.  One of the things that he cut back on was flying. Menier’s Syndrome affects the ear and […]
- [10 Pieces of Disinformation About SARS-CoV-2 (and the Truth You Deserve to Know)](https://publichealthactionnetwork.org/10-pieces-of-disinformation-about-sars-cov-2-and-the-truth-you-deserve-to-know/): The ongoing COVID-19 pandemic may no longer dominate headlines, but misinformation and disinformation about SARS-CoV-2 continue to spread, often faster than the virus itself. From minimizing its severity to questioning lifesaving tools like vaccines and masks, falsehoods can be dangerous, not just misleading. Let’s set the record straight on 10 of the most persistent myths still circulating about COVID-19. 1. What you’ve heard: “COVID is over.” The Truth: Wishful thinking, not fact.The COVID-19 pandemic is over, amirite? No, it is not. Case reporting essentially stopped years ago because of the “get back to work” mantra that permeates most countries, and […]

Kennedy Jr with regards to NIH, CDC, and the ACIP vaccine recommendation panel. Why Pride should matter to everyone Our first press release! PHAN recently helped distribute over 10,000 high-quality masks and over 5000 COVID tests to on-the-ground groups in North Carolina and New England. A new blog post about one person’s experience […]
- [Pandemic Protocols: How COVID Changed My High School](https://publichealthactionnetwork.org/pandemic-protocols-how-covid-changed-my-high-school/): from a guest blogger Infectious diseases come with every major civilization and every cultural rendezvous throughout history. Though our increasing interconnection spreads viruses farther and faster, the advancements that come with globalization allow us to protect ourselves more effectively. During the COVID pandemic in 2020, protecting our children meant online schooling from home–for some, this lasted a couple of months, and for others, this lasted for an entire year. Every district tackled this problem differently and it was sometimes difficult to tell which approach was right not just for safety, but also for well-being. As someone who was in high […]

- [Traveling COVID-safely in a not-COVID-safe world](https://publichealthactionnetwork.org/traveling-covid-safely-in-a-not-covid-safe-world/): With many folks getting ready to travel this summer, experts are expecting a COVID surge in the coming months, and we know it can be hard to figure out how to travel safely. If you’re traveling on a bus, train, or plane, we have several recommendations for steps you can take. Reminder that we are not doctors and you should do your own research to see what steps make the most sense for you, but these steps have worked for many of us here at PHAN. You don’t have to do all of these, but if you do as many […]

- [Long COVID in Children: Debunking the Myth and Understanding the Reality](https://publichealthactionnetwork.org/long-covid-in-children/): Early in the pandemic, it was widely believed that children were largely unaffected by COVID-19, especially in terms of long-term consequences. However, emerging research has dispelled this myth, revealing that children can and do develop Long COVID, even after mild or asymptomatic infections. This post aims to shed light on the realities of Long COVID in children, its symptoms, and the importance of recognizing and addressing this condition. Understanding Long COVID in Children What is Long COVID? Long COVID, also known as post-acute sequelae of SARS-CoV-2 infection (PASC), refers to a range of symptoms that persist for weeks or months […]
- [Long COVID and the Heart: Understanding Cardiovascular Impacts](https://publichealthactionnetwork.org/long-covid-cardiovascular-impacts/): While COVID-19 is primarily known for its respiratory effects, researchers now understand that the virus can also harm the heart and blood vessels, sometimes long after the initial infection has cleared. Even people who had mild or no symptoms during their acute infection have developed lingering cardiovascular problems. This post explores what those problems are, how they work, and what the latest science says about the risks. Increased Risk of Heart Attacks and Cardiovascular Disease What it means: Your heart pumps blood through arteries. A heart attack happens when blood flow is suddenly blocked, usually by a clot or buildup […]
- [Disappearing Act: Ellie’s Long COVID story](https://publichealthactionnetwork.org/disappearing-act-ellies-long-covid-story/): Among other things, Ellie was once a traveler. At age 66, she’s now retired, a time she’d envisioned would be spent peacefully pursuing her hobbies and seeing the world. Instead, she has to sleep on her living room couch because she can seldom walk up the stairs of her three-story home anymore. Several years into her battle with Long COVID, her bedroom has become an exotic locale.  A resident of Eastern Pennsylvania, a trip to her nearby hometown in New Jersey feels far beyond her capabilities now. And even her quieter hobbies, like writing children’s stories and making art, have […]

- [Why I Physically Fight My Masked Children](https://publichealthactionnetwork.org/why-i-physically-fight-my-masked-children/): Let me clarify: I fight my children because they ask for it. Daily. Hourly sometimes. I literally walk around on edge because at some point there’s going to be an altercation. Really – they will literally come up behind me and then proceed to sidekick me in the ribs (well, it’s usually a double sidekick, spin crescent kick, punch punch). This is what happens when you raise kids who participate in Taekwondo. What started as a fun and disciplined activity quickly became a way of life, and somewhere along the way, I realized that my adorable babies had transformed into…terrifying […]

Here’s a breakdown of the key standards across the U.S., China, Canada, South Korea, Europe, and beyond, including a closer look at elastomeric and reusable respirators. 🇺🇸 NIOSH N95 (USA) Standard Name: 42 CFR Part 84 – NIOSH-Approved RespiratorsThe NIOSH-approved N95 is one of the most trusted respirator types in the world.
