Five years ago next Tuesday, the World Health Organization declared a global pandemic that involves a new harmful virus, and through the planet, life, as we knew, melted. But the Cachered emergency began long before that. Back at the end of December 2019: Wuhan hospitals, China, full of mysterious pneumonia boxes. In January 2020, when the number of bodies began to increase and Wuhan was locked up, other countries began informing cases. The virus has spread like a poison in the invisible air through a quarantine cruise that sends to the coast of Japan. Italy has a hot infection point. One through one, American countries and states have issued house orders, and giant cities have been strangely silent. In a few weeks, New York hospitals were desperately filled in people of poor health. The dead stacked so temporarily that refrigerated trucks were used as transitional morgues.
Today, those occasions would possibly look like a remote nightmare for many other people. This is not the case of those who have lost expensive beings or for physical conditioning personnel who have treated other people when hospitals have been exceeded. They will never forget. However, through the maximum measures, Covid feels anywhere near the bad risk of those first years. In the United States, other people are not hospitalized and die from the disease in a position close to the rates that occurred in recent years. Experts have variable definitions of what it means that a virus becomes endemic, however, they agree that the frame virus is closer to this state now than in recent years.

“It is not at the time of an emergency that in the past,” explains Jennifer Nuzzo, professor of epidemiology and director of the Pandemic Center of the School of Public Health of the University of Brown. But she warns opposite to insurance. “We are not yet very intelligent to expect what Covid-19 will do,” explains Nuzzo.

Experts are adequate for the main explanation why Covid now reason death less and that serious ailments are a point of superior immunity in Sars-Cov-2. Most of the global people had the disease or have been vaccinated with respect to it, or both. Studies that Cocvid vaccines have stored millions of lives. And unlike the early 2020, the effective remedies (antivirals, which added Paxlovid and non -unusual steroids) are now available.
“This winter, there have been many respiratory diseases, but it was relatively little cocovent. And there was a descending tendency without stopping in terms of general amounts of serious diseases and death, “explains William Harage, an associate professor of epidemiology at the Harvard School of Public Health T. H. Chan. Scientists do not know if this downward trend will continue” Covid is with us in the long term in the long duration, since it will do, “explains Hainage. ” “It has improved, it is a value of value so that it is the value of the attention, it does not transfer it, it does not transmit it, it does not transmit it, it does not transmit it, it does not transfer it, it does not. Vulnerable people. “
However, Covid continues to kill more other people than the flu, although the flu has hospitalized more other people in the United States this winter. And Sars-Cov-2 triggers infection waves several times a year, shows wastewater tests. More than seven million international people have died of Covid, although it is probably a raw underestimation. And the virus continues to kill thousands of other people every month.

“It has been quite complicated for five years for everyone, for the global total,” said Maria Van Kerkhove, technical manager of a COCODID reaction to the World Health Organization. “I think that the global total needs to have happened and continue, which is quite understandable, because we have passed through anything that was incredibly complicated,” he said. But “I think we have to imply very obviously that Covid is not gone. “
Millions of other people had or suffered long covids, a capture prayer that describes postural symptoms that pass from gentle to weakening. The scientists began to examine the reasons for the long Covid. The evidence suggests that vaccines decrease the threat of raising the condition, but remedies are still difficult to reach.
However, with the worst of Covid in the rearview mirror in the rearview mirror, we can despite make an inventory of what happened and see to make sense of the reaction of the United States.
At the beginning of pandemic, scientists and public fitness experts had to react in a genuine time to a new logogenic pathogen, and mistakes were made. American officials have bothered Cocovid’s initial verification strategy, for example. At first, all controls would be carried out in the centers for disease control and prevention, which created a severe strangulation neck. Exacerbating this, the verification of the CDC itself proved to be defective, which makes the effects not conclusive. In long -term pandemics, checks are made to have much faster and largely through the personal sector, according to Mavens.
In addition, Public Fitness officials in WHO and the United States government have taken to recognize that SRAS-COV-2 can extend through small rubble or aerosols in the air. Some mavens have actively warned to the public who uses a mask in the front, announcing that they were ineffective or that physical care providers needed it and had to be preceded in the middle of the initial supply.
“I think the challenge was the use, in particular, of this word” airborne “, which had a technical meaning. It took 3 years to replace the terminology connected to the air transmission, and now we say” in the air, “explains Van Kerkhove. But rejects the story that has not identified the prospective of the virus to spread in this way. ” We have advised air precautions. Fitness workers. However, she recognizes that messages may have been clearer.
During those first days and weeks of uncertainty, although terrifying news about the virus around the world, in all Americans, with some exceptions, first grouped in opposition to a non -unusual threat. The manifestations were limited or canceled. Those who can do so have stayed at home or at school to attend “flattening the curve” of the transmission. The objective was to reduce the speed of the number of other people inflamed with the Cocvid and become seriously with poor health to prevent hospitals from being overwhelmed. And in fact, the studies showed that the flattening of the curve worked. The problem, according to experts, is that there was no excursion strategy.
“The concept of flattening the curve as a rest button: measures that you can use to buy time to prevent hospitals from exceeding, so it can protect them for six months” or until we have a vaccine, “says Nuzzo. But there is no transparent finish point. ” We didn’t have the next aligned phase. “

Hainage is suitable for the United States to have been smarter with the orders of the house. “I also believe that we really lost a chance, almost in the summer of 2020, because at that time in the United States, the initial surge had been dominated,” he said.
Perhaps no facet of the American pandemic reaction has been as fiercely discussed as school closure. “The consultation of schools and diseases is a third political railroad at the time no one needs to communicate about what, if necessary, we do to protect young people in schools,” explains Nuzzo, who wrote a March 2020 editorial discussing opposite to the final schools.
These closures had a meaning in the first days and weeks of the pandemic, when the effects of the virus were still unknown and we even lack fundamental treatments, not to mention vaccines. However, many other people have expressed their outrage to see how long they lasted, or have wondered if they were mandatory at all. Some argued that the virus had caused softer infections in young people; It was true, but not in any case. But young protectors were not the only end point in schools; He also had to avoid transmission channels to vulnerable adults such as teachers, personnel and members of the adult family.

Over time, however, intellectual aptitude and social prices to remain young at home and have online schooling began to pass it. Long general closures may have been replaced through more sustainable interventions, such as masking and air quality, thanks to higher ventilation systems.
“I think what really was unfortunate is that the courier of public aptitude was not clear, or it was much more definitive than it deserved to have been,” said Michael Ostrolm, president of Public Fitness and director of the Center for Research and Policy of Infectious Diseases of the University of Minnesota. “Then everything happened what we said before, and that made other people challenged how righteous we were: when, in fact, it was never discouraged. It was a consultation of seeking to speak uncertainty, and it was a genuine problem. ” “
Despite these challenges, there were undeniable triumphs in the clinical reaction to the pandemic. In the 11 months after the sequence of sequence genetically, the United States had developed two RNM vaccines that were prevented very well. These are the fastest vaccines ever made, explains Paul Offer, a doctor from the Department of Infectious Diseases of the Children’s Hospital in Philadelphia. “For me, the hero of this pandemic are the National Institutes of Health,” whose scientists have thrown a giant component of the basably effective RNM vaccine bases, “he says. ” And then what Trump’s management has done was the deformation speed operation, a commitment of $ 11 billion to basically bet on six horses to earn a breed and was a production production. “

But “vaccines surely do nothing when they are sitting there in a bottle,” says Hainage. “They want to be in arms. ” Unfortunately, vaccines, like many facets of the pandemic, were politicized in the middle of a constant dam of flagrant lies and misinformation of President Donald Trump and many followers, and a small but vocal component of the population refused to download them. In many areas, other people who wore a mask were mocked or reprimanded and some were physically attacked. Consequently, the population of the states and the counties ruled through the Republicans died at higher rates than the other people in the Democratic home.
The fracture underlines how polarization is the answer. A recent investigation by Pew revealed that approximately 3 out of 4 American adults say that pandemic has done more to keep the country away than to unite it. Americans have been individualistic and many other people have not tried to use a mask or be vaccinated, even when such recommendations aimed to protect others. The concept of this type of collective altruism is difficult to speak and the public physical conditioning messaging occasionally has failed.
“I think that the worst imaginable scenario you can have, when you are in the middle or the beginning of an evolving pandemic, is the deep degree of department we have and even in our country,” said Anthony Fauci, the remarkable doctor and former leader of the National Institute of Allergies and Infectious Diseases, in an interview with the scientific scientific scientist. “It’s like being at war. The unusual enemy is the virus. And we act on many scenarios and in many tactics as if the enemy outside others. “
In fact, Fauci, very celebrated as a hero and “American doctor” at the beginning of the pandemic, was in the end that through Trump and many of his disciples such as the face of the orders of the house and other social restrictions. The mask and evidence needs of vaccination have attracted a strong reaction and since then some US counties have banned public masking (with some exceptions). Some states have prohibited crocodidia vaccine mandates. These prohibitions would possibly unfairly point to other disabled and immunocompromised people and can also leave the total population more vulnerable to the epidemics of long -term diseases.

One thing is safe: the global will delight in other pandemics, probably in our lives. The maximum probably guilty would be a type of flu, as in the 1918 pandemic.
In fact, the United States is already struggling with an epidemic of consistent expansion of Aviar H5N1 influenza, or avian flu, which infects wild birds, poultry and, in March 2024, dairy farm animals. The virus is very fatal for corral birds, which triggers large networks that have higher eggs. Historically, H5N1 has not been gently transmitted to humans. But in the few epidemics that occurred among people, he experienced an incredible mortality rate of almost 50%. In the existing epidemic that affects dairy and poultry farm animals in the United States, 70 human instances have been informed, more commonly gentle, and deaths.
Experts criticized the H5N1 reaction among federal and state physical conditioning agencies, warns that checks have been inadequate and that infections are probably lost. Dairy farms have doubted the virus about the considerations of waste of income, and agricultural staff, many of which are undocumented, care to waste their work or be expelled if they are looking for medical attention. The election of an intensely anti -immigrant president has only exacerbated those concerns.
It is far from sure that H5N1 will become a pandemic. The virus deserves to mutate a shape that extends gently among humans, which has not yet happened. But if we, in the United States, face a pandemic, whatever the cause, in some way, we can now be worse supplied that we did when we face Cocovan.
“At this time, I think we are less ready for the next pandemic than in 2020,” Osterholm said. “One of the maximum weapons that we have in an opposite combat [a pandemic virus is the confidence of public aptitude recommendations. And I think that at this stage, it is a massive challenge for the public, in terms of lack of vaccine confidence. “
The existing threats for the establishment of science themselves exacerbate the problem. Trump has appointed Anti -Salaries, the Secretary of Health and Social Services Robert F. Kennedy, Jr. , to direct federal fitness agencies. He made radical cuts to the CDC, NIH and other clinical agencies. And in one of Trump’s first decrees, he announced his goal of withdrawing the United States from WHO.

“You have a public fitness infrastructure,” says offer. You have other people who are leaders of various agencies, such as NIH or CDC or [Food and Medicines Administration] and now [the Ministry of Health and Social Services], who have contempt for those agencies, which do not accept as true with those agencies. »
However, in other aspects, we can be better prepared, adds Nuzzo. “People have experienced a recently pandemic, and do not forget it to some extent,” he said. Contrary to what happened with Covid, if a flu pandemic had to hit us, we can use tests for the virus and safe vaccines that we have already stored. “People regularly perceive influenza disease. We have been reading H5 infections for 25 years, so we know the virus a bit and how it affects the body, ”explains Nuzzo. “That said, there will be challenges. ” [Editor Note: H5 is a subtype of avian flu that includes H5N1 and other viruses. ]
WHO is Van Kerkhove that we are more in a position in some aspects and less in others. “We are [better prepared] because we all pass through this, and what we learned at the beginning of the cocovan was: the countries with the trauma and the delight of that type of epidemics, with the Mrs. , with seas, with an avian flu, they were prepared older. They acted quickly. They knew how bad it would be. And now, now each country was revealed.
But this preparation point is a challenge. “How can we impulse and efforts on governments, organizations and establishments to ensure that we continue to invest in public health, we continue to invest in prevention? Prevention is a very complicated sale,” explains Van Kerkhove.
She expects the United States to replace her minds in paintings with whom and other countries. “I think it is of interest to the Member States of the paintings together in combination on the preparation of the pandemic, on surveillance, detection, the evaluation of threats,” says Van Kerkhove, “because those pathogens do not respect borders. “
