COVID-19 Frequently Asked Questions | New York Times

Updated September 1, 2020

  • Why is it safer to spend time together outside?
    • Pandemic life is safer outdoors. Outdoor gatherings lower risk because wind disperses viral droplets, and sunlight can kill some of the virus. Open spaces prevent the virus from building up in concentrated amounts and being inhaled, which can happen when infected people exhale in a confined space for long stretches of time, said Dr. Julian W. Tang, a virologist at the University of Leicester. Thus, while the risk of outdoor transmission is low, it can happen.
    • “The virus load is important,” said Eugene Chudnovsky, a physicist at Lehman College and the City University of New York’s Graduate Center. “A single virus will not make anyone sick; it will be immediately destroyed by the immune system. The belief is that one needs a few hundred to a few thousand of SARS-CoV-2 viruses to overwhelm the immune response.”

  • What are the symptoms of coronavirus?
    • In the beginning, the coronavirus seemed like it was primarily a respiratory illness — many patients had fever and chills, were weak and tired, and coughed a lot, though some people don’t show many symptoms at all. Those who seemed sickest had pneumonia or acute respiratory distress syndrome and received supplemental oxygen. By now, doctors have identified many more symptoms and syndromes. In April, the C.D.C. added to the list of early signs sore throat, fever, chills and muscle aches. Gastrointestinal upset, such as diarrhea and nausea, has also been observed. Another telltale sign of infection may be a sudden, profound diminution of one’s sense of smell and taste. Teenagers and young adults in some cases have developed painful red and purple lesions on their fingers and toes — nicknamed “Covid toe” — but few other serious symptoms.

    Why does standing six feet away from others help?

    • The coronavirus spreads primarily through droplets from your mouth and nose, especially when you cough or sneeze. The C.D.C., one of the organizations using that measure, bases its recommendation of six feet on the idea that most large droplets that people expel when they cough or sneeze will fall to the ground within six feet. But six feet has never been a magic number that guarantees complete protection. Sneezes, for instance, can launch droplets a lot farther than six feet, according to a recent study. It’s a rule of thumb: You should be safest standing six feet apart outside, especially when it’s windy. But keep a mask on at all times, even when you think you’re far enough apart.

    COVID-19 risk factors for severe disease

    • Based on currently available information and clinical expertise, older adults and people with underlying medical conditions are at higher risk for severe illness from COVID-19. According to the CDC, “…6% of the deaths, COVID-19 was the only cause mentioned.” Essentially, 94 percent of Americans who have died from coronavirus from the week ending February 1, 2020 to the week ending August 22, 2020 had, on average, almost three comorbidities that played a role in their death.
    • According to CDC’s report, the leading comorbidities among COVID-19 deaths were respiratory diseases, circulatory diseases, sepsis, malignant neoplasms, diabetes, obesity and Alzheimer’s disease, respectively.
    • “Anecdotally, there are several stories of cases in which people with COVID-19 had deadly heart attacks, yet these cases were coded as COVID-19 deaths. In one extreme case, a Florida man who died in a motorcycle crash happened to also have COVID-19 at the time, yet was coded as having died from COVID-19, not because of the motorcycle accident.” Many clinicians are putting COVID-19 on death certificates when it might not be entirely accurate because they died infected with coronavirus and not because of coronavirus.
