Polio is coming back. Thanks Anti-Vaxxers!

Earlier this month, poliovirus was found in sewage in areas outside New York City, marking the first domestic outbreak of this potentially deadly and disabling virus since the 1970s.

COVID. Monkey pox. Now polio. If infectious diseases seem to us to come faster, spread more widely, and last longer than generations, that’s because, as health professionals, there’s basically one thing we can do to reliably prevent outbreaks. Getting vaccinated is something millions of people in the United States and the developed world can’t do.

For the first time since the early 1990s life expectancy is actually declining For many groups in the US The fifth of the Americans have refused Covid vaccines for themselves or their children, according to the Centers for Disease Control and Prevention. the and only 65 percent of residents For example, in some areas outside of New York (such as Orange and Rockland counties), the national average is 80 percent. When polio re-emerged in the United States last month (the first outbreak in the US since 1979), it should come as no surprise that the first diagnosis was in Rockland.

We travel back in time and, in a sense, return to the dark ages before vaccines. Mary Fissell, a historian of medicine at Johns Hopkins University, said: “It’s scary how much people are dismissive of scientific discoveries and different kinds of expertise these days.”

It’s safe to say that most people don’t know what bad things could happen if we continue down this path. “It used to be worse!” Fissell said.

The developed world’s success in preventing disease has created a kind of complacency, or worse, conspiracy thinking, as entire generations have assumed that these diseases will never or will not return. Misinformation on social media has exacerbated the problem, with many staunch anti-vaxxers blaming vaccines for vaccine-preventable diseases.

We as a species seem to have forgotten how scary and scary the world was before vaccines. “What’s new now is that several generations of American children have lived largely without the risk of dying from infectious disease or even getting seriously ill,” Fissell said. “Polio was probably the last big killer, and the generation that experienced it as children is now older.”

Only in the 19th and 20th centuries, with the rapid development of public health, communication and, most importantly, vaccines, were we able to consistently prevent, contain, or even eradicate diseases like smallpox or polio that, in previous centuries, would have killed millions.

The Black Death, spread by fleas and person-to-person contact, killed hundreds of millions of people (about half the population) in Europe and North Africa in the 1340s and 50s.

There were no antibiotics or vaccines. “When someone got sick, there wasn’t much you could do,” said John Abert, historian and author. The Black Death: A New History of the Great Death in Europe, 1347-1500.

To slow the spread of the disease, local authorities would confine infected people to their homes for 40 days, which gave us the term “quarantine.” (“Quarante” means “40” in French.) If you were lucky and loved, your friends and neighbors would bring food to your house. If you were unlucky or disliked, you would starve.

For centuries, quarantine was humanity’s primary defense against infectious diseases. It has been subdued at best, as was the case during the months of widespread social distancing at the start of the Covid pandemic.

But quarantine, whether in the 14th century or the 21st, is unpopular and difficult to enforce. To warn Latest Covid guidance The US Centers for Disease Control and Prevention does not recommend that people self-isolate after being exposed to Covid. Keeping infected people at home didn’t stop the Covid pandemic, and it didn’t prevent mass deaths 700 years ago.

When quarantine was the only means of prevention, infectious diseases were a constant threat, especially to children. “Two or three hundred years ago, children under the age of five died every summer from diarrhea caused by milk or water containing bacteria,” Fissel explained. “Epidemic diseases like smallpox and cholera, and centuries before that, plagues that swept across communities, everyday infectious diseases like whooping cough, all caused lasting damage.”

Then in 1798, British doctor Edward Jenner invented the first smallpox vaccine. Over the next 150 years, slowly but steadily, scientists developed more vaccines and health authorities used them on more and more people.

Vaccines against smallpox, plague, tetanus, measles, poliomyelitis, and other diseases have made these diseases rare, easily contained outbreaks, and even eradicated smallpox globally.

“Over the past century or so — since the 1860s, in fact — we’ve built a series of institutions and cultures in public health that protect us from the worst that nature has to offer,” said Ohio State University health historian John Brooke. .

In the 1970s, humanity entered a new era of public health, most notably the eradication of smallpox in 1980. “The combination of vaccines and antibiotics has made life much safer, as has basic public health infrastructure like sanitation,” Fissell said. .

But even in the 70s, the anti-vaccine attitude became tougher. In 1976, the U.S. government’s effort to vaccinate all Americans against swine flu failed because of protests from a vocal minority. “That’s when vaccine-skepticism rears its head for the first time,” Abert said. TThe effects of swine flu, which emerged 25 years after widespread childhood vaccination, can cause paralysis or death. A generation later, people began to forget how devastating this disease and other diseases that required vaccination were.

Illnesses can get much worse before they get better. Most of the worst infectious diseases “zoonism”, They circulate constantly in the animal population and occasionally jump to humans. Accelerating deforestation and increasing the illegal trade of wildlife for meat, counterfeit medicine and pets provide greater opportunities for zoonotic viruses such as novel coronavirus and monkeypox to infect humans.

Declines in vaccinations will exacerbate these outbreaks, Abert said. “Vaccination is the only answer to the emerging pandemic. We need to address vaccine-skepticism or make vaccines mandatory.” But he acknowledged that the new mandates were politically impossible in what he called “divided” countries.

As Brooke points out, global disaster is not inevitable. “Will anger over government spending and individual liberties lead to the collapse of the public health bubble that protects us from nature?” he asked. “Let’s hope not.”

As Brooke points out, most people are willing, even eager, to vaccinate against the worst diseases. “Anti-vax culture is a growing reality, but we must not allow the journalistic mantra of ‘equal time for both sides’ to mask the weight of public opinion.”

But the trends — fewer vaccinations, more infectious diseases — are not encouraging. They harken back to a time before vaccines, when we got sick more often, died younger, confined people to their homes, and tried, and often failed, to contain viral outbreaks. “History doesn’t repeat itself, but echoes do, and we need to pay attention,” says Oxford University historian and author James Belich. The Future of Global History.

It takes hard work to turn the arc of history toward a longer, healthier life. Back, that is, widespread vaccination. “For example, it’s difficult to understand why people refuse vaccines,” Fissell said. “It depends on politics and religious beliefs and many other factors.”

No one can solve our pandemic problems overnight. But there is lot of of things everything can help. Trusted experts. Don’t spread fake news. Most importantly, get vaccinated and encourage your friends and family to get vaccinated too. Not just for covid though each A disease for which there is a safe and effective vaccine.

“We have to make a choice as a society,” Abert said. Vaccines. Or a disease.
