Below is the knowledge from someone`s blog to help more people to know the COVID-19 virus: 

Even in less challenging times, many of us try to avoid close contact with someone who is sneezing, coughing, or running a fever to avoid getting sick ourselves. Our attention to such issues has now been dramatically heightened by the emergence of a novel coronavirus causing a pandemic of an illness known as COVID-19.

Many have wondered if we couldn’t simply protect ourselves by avoiding people with symptoms of respiratory illness. Unfortunately, the answer is no. A new study shows that simply avoiding symptomatic people will not go far enough to curb the COVID-19 pandemic. That’s because researchers have discovered that many individuals can carry the novel coronavirus without showing any of the typical symptoms of COVID-19: fever, dry cough, and shortness of breath. But these asymptomatic or only mildly ill individuals can still shed virus and infect others.

This conclusion adds further weight to the recent guidance from U.S. public health experts: what we need most right now to slow the stealthy spread of this new coronavirus is a full implementation of social distancing. What exactly does social distancing mean? Well, for starters, it is recommended that people stay at home as much as possible, going out only for critical needs like groceries and medicines, or to exercise and enjoy the outdoors in wide-open spaces. Other recommendations include avoiding gatherings of more than 10 people, no handshakes, regular handwashing, and, when encountering someone outside of your immediate household, trying to remain at least 6 feet apart.

These may sound like extreme measures. But the new study by NIH-funded researchers, published in the journal Science, documents why social distancing may be our best hope to slow the spread of COVID-19 [1]. Here are a few highlights of the paper, which looks back to January 2020 and mathematically models the spread of the coronavirus within China:

• For every confirmed case of COVID-19, there are likely another five to 10 people with undetected infections.
• Although they are thought to be only about half as infectious as individuals with confirmed COVID-19, individuals with undetected infections were so prevalent in China that they apparently were the infection source for 86 percent of confirmed cases.
• After China established travel restrictions and social distancing, the spread of COVID-19 slowed considerably.

The findings come from a small international research team that included NIH grantee Jeffrey Shaman, Columbia University Mailman School of Public Health, New York. The team developed a computer model that enabled researchers to simulate the time and place of infections in a grid of 375 Chinese cities. The researchers did so by combining existing data on the spread of COVID-19 in China with mobility information collected by a location-based service during the country’s popular 40-day Spring Festival when travel is widespread.

As these new findings clearly demonstrate, each of us must take social distancing seriously in our daily lives. Social distancing helped blunt the pandemic in China, and it will work in other nations, including the United States. While many Americans will likely spend weeks working and studying from home and practicing other social distancing measures, the stakes remain high. If this pandemic isn’t contained, this novel coronavirus could well circulate around the globe for years to come, at great peril to us and our loved ones.

As we commit ourselves to spend more time at home, progress continues to be made in using the power of biomedical research to combat this novel coronavirus. A notable step this week was the launch of an early-stage human clinical trial of an investigational vaccine, called mRNA-1273, to protect against COVID-19 [2]. The vaccine candidate was developed by researchers at NIH’s National Institute of Allergy and Infectious Diseases (NIAID) and their collaborators at the biotechnology company Moderna, Inc., Cambridge, MA.

This Phase 1 NIAID-supported trial will look at the safety of the vaccine—which cannot cause infection because it is made of RNA, not the whole coronavirus—in 45 healthy adults. The first volunteer was injected this past Monday at Kaiser Permanente Washington Health Research Institute, Seattle. If all goes well and larger follow-up clinical studies establish the vaccine’s safety and efficacy, it will then be necessary to scale up production to make millions of doses. While initiating this trial in record time is a reason for hope, it is important to be realistic about all of the steps that still remain. If the vaccine candidate proves safe and effective, it will likely take at least 12–18 months before it would be widely available.

In the meantime, social distancing remains one of the best weapons we have to slow the silent spread of this virus and flatten the curve of the COVID-19 pandemic. This will give our health-care professionals, hospitals, and other institutions more valuable time to prepare, protect themselves, and aid the many people whose lives may be on the line from this coronavirus.

Importantly, saving lives from COVID-19 requires all of us—young, old and in-between—to take part. Healthy young people, whose risk of dying from coronavirus is not zero but quite low, might argue that they shouldn’t be constrained by social distancing. However, the research highlighted here demonstrates that such individuals are often the unwitting vector for a dangerous virus that can do great harm—and even take the lives of older and more vulnerable people. Think about your grandparents. Then skip the big gathering. We are all in this together.
