Polio Feels Like the Past, So Why Is It Back in the News

Polio is back in the headlines because the CDC recently updated its global polio travel notice.

And I get why seeing that catches people off guard.

For a lot of parents in the U.S., polio feels like something from another generation. It can sound like one of those diseases we learned about in history, not something that still deserves our attention now. But that’s also part of the point. It feels far away to many of us because vaccines have done exactly what they were meant to do.

The current CDC advisory applies to countries where poliovirus has been found in people or in environmental samples, and the guidance for travelers is to make sure they are up to date on polio vaccination. So yes, this is tied to travel. But I also think it opens a bigger conversation, because when polio shows up in the news again, it is a reminder of what vaccines have protected families from for generations.

That’s the part I don’t want lost in the headline.

This isn’t just a travel story. It’s also a reminder that some diseases can start to feel rare or unimportant only because prevention worked so well that many of us never had to see the worst of them up close.

What’s happening right now

The reason polio is back in the conversation right now is because the CDC recently updated its global travel notice for polio. The notice applies to countries where poliovirus has been detected within the past 13 months, and the CDC is recommending that travelers be up to date on polio vaccination before international travel. For adults who already completed their routine vaccine series and are traveling to a destination with circulating poliovirus, CDC says a single lifetime booster may also be recommended.

So this is not about a sudden widespread polio outbreak across the United States. It’s a global travel advisory and a reminder that polio still exists, still circulates in some parts of the world, and still matters enough that vaccination guidance remains very relevant.

Polio is serious enough on its own

I also think it’s worth saying that we can name this headline for what it is…

Just say POLIO. The paralyzing disease is polio, and we have a vaccine for it! 

This is a virus that can affect the nervous system. Many people who get polio do not end up with obvious symptoms, which is part of what can make it easy to underestimate. But when polio does cause severe illness, it can cause meningitis and paralysis. Paralysis is the most serious outcome because it can lead to permanent disability and death. Between 2 and10 out of 100 people with paralytic polio die because the virus affects the muscles used for breathing.

That matters because sometimes headlines try to make health stories sound more intense than they need to be. In this case, I don’t think we need that. Just hearing “polio” should be enough to remind us why this vaccine has mattered for generations.

Polio was once one of the most feared diseases in the United States, and it was eliminated here because of the vaccine. That’s what I’d want parents to hold onto before anything else: this is not about fear for fear’s sake. It’s about remembering what this disease can actually do, and why preventing it still matters.

Vaccines can start to feel optional only after they’ve worked

In countries like the U.S., it can be easy to forget what polio once meant for families because most of us have never had to see it up close. That distance can create a false sense that the vaccine is unnecessary, when really the opposite is true. For some people, it only feels unnecessary because it worked. Polio became rare here through vaccination, not because it stopped being a serious disease.

Around the world, many families are not skipping vaccines because they do not value them. They are facing war, displacement, fragile health systems, and humanitarian crises that make routine care much harder to access. WHO and UNICEF show that about a quarter of the world’s infants live in just 26 countries affected by fragility, conflict, or humanitarian crises, yet those countries account for half of all unvaccinated children globally.

That is part of what makes these headlines hit differently.

In some places, families would do anything for steady access to vaccines that others question because the diseases feel far away. That distance is not proof the disease no longer matters. It is proof public health worked.

What I’d want parents to take from this

For me, the takeaway here is not panic, but having perspective.

If your child is up to date on vaccines, that protection matters. And if your family is traveling internationally, this is a good reminder to double check that everyone is up to date on polio vaccination before you go. CDC also notes that some previously vaccinated adults traveling to destinations with circulating poliovirus may be advised to get a one-time lifetime booster.

I also think this is a reminder of something bigger: vaccines can start to feel easy to question only after they have done their job so well that many of us no longer live with the fear of these diseases up close. Polio feels distant for many families in the U.S. not because it stopped being serious, but because vaccination changed that reality.

And maybe that is the simplest place to land. This headline is a reminder of why routine vaccines still matter, even when the diseases they prevent can feel far away.

On The Podcast

Surrogacy is often talked about in headlines or celebrity news, but rarely explained in a way that helps people truly understand the experience behind it. In this episode, I’m joined by surrogacy consultant Jessie Jaskulsky, founder of Surrogacy Simplified, to talk openly about what the surrogacy process actually looks like, the misconceptions that surround it, and the emotional reality many families face while trying to grow their family.

Jessie shares her personal path through pregnancy loss, infertility, and ultimately two surrogacy journeys that helped her welcome her daughters. From navigating the logistics and cost to managing grief, uncertainty, and public judgment, this conversation brings compassion and clarity to a topic that is often misunderstood.

In this special follow-up episode, Dr. Mona shares the full live conversation recorded at Children’s Hospital Colorado in front of more than 100 clinicians. The discussion centers on a reality many pediatricians and parents are facing every day: families are no longer walking into the exam room with just their child, they are also bringing TikTok, Instagram, YouTube, viral clips, and online comment sections with them.
