One of the biggest mysteries surrounding the coronavirus is how quickly it spread around the world. It started in central China and, within three months, had spread to every continent except Antarctica, disrupting the daily lives of millions of people. Behind the rapid spread was a fact that caught scientists by surprise, alarmed health authorities and undermined early containment efforts: the virus could be spread by healthy people. As workers return to offices, children prepare to resume school, and people desperate for normality begin to visit shopping malls and restaurants, new scientific data speaks to an ominous reality: If disease can be transmitted by healthy people, then maybe she will be impossible to restrain. "It can be deadly, and yet 40 percent of people may not know they have it," says Dr. Eric Topol, head of the Scripps Research Institute. Researchers talk about the frightening possibility of the silent spread of the virus by carriers without symptoms or with weak symptoms.

Science speaks The small but powerful coronavirus can penetrate a human cell, stabilize there, and multiply into tens of thousands in a single day. Virus levels rise before the first cough. And to the surprise of scientists, about 4 in 10 infected people have no symptoms at all. The infidelity of this virus is the focus of many scientists now that societies are reopening. They wonder what happens if silent spreaders aren't discovered before it's too late. Travelers without a cough can easily pass through airport checkpoints. Workers without fever cannot be detected by temperature checks.
People who do not feel tired or have no pain attend business meetings, infecting others. And the outbreaks may resume. The first signs As early as January, there were signs that people could carry the virus without showing symptoms. However, many scientists were not convinced. The concept that people can unwittingly spread disease has never been easy to grasp, from the polio epidemic in mid-20th century America to the spread of HIV decades later. When COVID-19a emerged, health officials thought it would be like other coronaviruses and that people would infect others more easily when they showed symptoms such as a cough or fever. "We thought this would be like SARS: a long incubation period and no transmission during the incubation period," says Lauren Ancel Meyers, of the University of Texas at Austin.
