En lo personal, yo utilizo este antivirus pues es bastante ligero, es decir, ocupa pocos recursos de mi sistema y es particularmente bueno para detectar amenazas. Actualmente es considerado como uno de los mejores antivirus que hay en el mercado.

Claro que como todo lo realmente bueno, tiene un costo. Despite ample warning, the U. And despite its considerable advantages—immense resources, biomedical might, scientific expertise—it floundered. While countries as different as South Korea, Thailand, Iceland, Slovakia, and Australia acted decisively to bend the curve of infections downward, the U. Since the pandemic began, I have spoken with more than experts in a variety of fields. A sluggish response by a government denuded of expertise allowed the coronavirus to gain a foothold.

A bloated, inefficient health-care system left hospitals ill-prepared for the ensuing wave of sickness. The same social-media platforms that sowed partisanship and misinformation during the Ebola outbreak in Africa and the U. The U. Health experts , business leaders, and even middle schoolers ran simulated exercises to game out the spread of new diseases. In , I wrote an article for The Atlantic arguing that the U. Its symptoms can be severe enough to kill millions but are often mild enough to allow infections to move undetected through a population.

Deadlier pathogens almost certainly exist. Wild animals harbor an estimated 40, unknown viruses , a quarter of which could potentially jump into humans. How will the U. Normal led to this. Normal was a world ever more prone to a pandemic but ever less ready for one. To avert another catastrophe, the U. It needs a full accounting of every recent misstep and foundational sin, every unattended weakness and unheeded warning, every festering wound and reopened scar.

A pandemic can be prevented in two ways: Stop an infection from ever arising, or stop an infection from becoming thousands more. The first way is likely impossible. There are simply too many viruses and too many animals that harbor them. Bats alone could host thousands of unknown coronaviruses; in some Chinese caves, one out of every 20 bats is infected. Many people live near these caves, shelter in them, or collect guano from them for fertilizer. Based on antibody testing in rural parts of China , Peter Daszak of EcoHealth Alliance, a nonprofit that studies emerging diseases, estimates that such viruses infect a substantial number of people every year.

But it takes just one transmissible virus to start a pandemic. Sometime in late , the wrong virus left a bat and ended up, perhaps via an intermediate host, in a human—and another, and another.

Eventually it found its way to the Huanan seafood market, and jumped into dozens of new hosts in an explosive super-spreading event. Carlson said the biggest factors behind spillovers are land-use change and climate change, both of which are hard to control. Our species has relentlessly expanded into previously wild spaces. Curtailing those viruses after they spill over is more feasible, but requires knowledge, transparency, and decisiveness that were lacking in Much about coronaviruses is still unknown.

There are no surveillance networks for detecting them as there are for influenza. There are no approved treatments or vaccines. Coronaviruses were formerly a niche family, of mainly veterinary importance. Four decades ago, just 60 or so scientists attended the first international meeting on coronaviruses.

Their ranks swelled after SARS swept the world in , but quickly dwindled as a spike in funding vanished. The same thing happened after MERS emerged in In the age of cheap air travel, an outbreak that begins on one continent can easily reach the others. SARS already demonstrated that in , and more than twice as many people now travel by plane every year. To avert a pandemic, affected nations must alert their neighbors quickly. In , China covered up the early spread of SARS, allowing the new disease to gain a foothold, and in , history repeated itself.

Doctors who tried to raise the alarm were censured and threatened. By then, an estimated 10, people in 20 countries had been infected, and the virus was spreading fast. Under President Donald Trump, the U.

America First was America oblivious. Even after warnings reached the U. Since before his election, Trump has cavalierly dismissed expertise and evidence.

American intelligence agencies warned about the coronavirus threat in January , but Trump habitually disregards intelligence briefings. The secretary of health and human services, Alex Azar, offered similar counsel, and was twice ignored. Instead, he focused on the border.

On January 31, Trump announced that the U. Travel bans make intuitive sense, because travel obviously enables the spread of a virus. But in practice, travel bans are woefully inefficient at restricting either travel or viruses. They prompt people to seek indirect routes via third-party countries, or to deliberately hide their symptoms. Travel bans may sometimes work for remote island nations, but in general they can only delay the spread of an epidemic —not stop it.

This was predictable. A president who is fixated on an ineffectual border wall, and has portrayed asylum seekers as vectors of disease, was always going to reach for travel bans as a first resort. And Americans who bought into his rhetoric of xenophobia and isolationism were going to be especially susceptible to thinking that simple entry controls were a panacea.

And so the U. Although the disease first arrived in the U. The country could have used that time to prepare. With impunity, the virus spread. As the coronavirus established itself in the U. For years, Pardis Sabeti, a virologist at the Broad Institute of Harvard and MIT, has been trying to create a surveillance network that would allow hospitals in every major U.

The CDC developed and distributed its own diagnostic tests in late January. These proved useless because of a faulty chemical component. Tests were in such short supply, and the criteria for getting them were so laughably stringent, that by the end of February, tens of thousands of Americans had likely been infected but only hundreds had been tested.

Diagnostic tests are easy to make, so the U. Worse, it had no Plan B. Private labs were strangled by FDA bureaucracy. Read: How the coronavirus became an American catastrophe. Water running along a pavement will readily seep into every crack; so, too, did the unchecked coronavirus seep into every fault line in the modern world.

Consider our buildings. In response to the global energy crisis of the s, architects made structures more energy-efficient by sealing them off from outdoor air, reducing ventilation rates. Chan School of Public Health. Energy efficiency is a pillar of modern climate policy, but there are ways to achieve it without sacrificing well-being. The indoor spaces in which Americans spend 87 percent of their time became staging grounds for super-spreading events.

One study showed that the odds of catching the virus from an infected person are roughly 19 times higher indoors than in open air.

Shielded from the elements and among crowds clustered in prolonged proximity, the coronavirus ran rampant in the conference rooms of a Boston hotel, the cabins of the Diamond Princess cruise ship, and a church hall in Washington State where a choir practiced for just a few hours. The hardest-hit buildings were those that had been jammed with people for decades: prisons.

Many American prisons are packed beyond capacity, making social distancing impossible. Soap is often scarce. Inevitably, the coronavirus ran amok. By June, two American prisons each accounted for more cases than all of New Zealand. One, Marion Correctional Institution, in Ohio, had more than 2, cases among inmates despite having a capacity of 1, Other densely packed facilities were also besieged.

More than 50, residents and staff have died. At least , more have been infected. Before the pandemic, three in four nursing homes were understaffed , and four in five had recently been cited for failures in infection control. Read: Another coronavirus nursing-home disaster is coming. Rather than girding these facilities against the pandemic, the Department of Health and Human Services paused nursing-home inspections in March, passing the buck to the states.

Some nursing homes avoided the virus because their owners immediately stopped visitations, or paid caregivers to live on-site. But in others, staff stopped working, scared about infecting their charges or becoming infected themselves. In some cases, residents had to be evacuated because no one showed up to care for them. That system pairs uneasily with a national temperament that views health as a matter of personal responsibility rather than a collective good.

At the end of the 20th century, public-health improvements meant that Americans were living an average of 30 years longer than they were at the start of it. Maternal mortality had fallen by 99 percent; infant mortality by 90 percent.
