The director of the U.S. Centers for Disease Control and Prevention (CDC) said the spread of the virus could be 10 times greater than previously thought,media reported. The agency has been evaluating antibody test results from March to May 2020, and their findings give them a new understanding of the number of cases of new coronary pneumonia.
The move follows a new study of cases of the new coronavirus in the United States, based on blood samples taken in 10 U.S. regions where between 1 and 6.9 percent of people are believed to have contracted new coronary pneumonia at some point. Although antibody tests do not show whether a person is currently infected with the virus, it can show whether their body has been infected before, resulting in an immune system response.
Researchers with new crown pneumonia are particularly interested in trying to figure out the proportion of asymptomatic people infected. These so-called asymptomatic individuals may unknowingly spread the virus to others, so even those who feel well are advised to keep their social distance and wear masks.
In March, the CDC’s director, Robert F. Kennedy, said he was “very happy” with the U.S. R. Redfield revealed that asymptomatic people may account for 25 percent of all infections.
There are some disturbing outliers in the report. For example, one of the states is estimated to have 23.8 times as many cases as reported, although Redfield cautions that this may be the exception rather than the rule, “which may be due to underreporting or under-testing at data collection.” “
“For most regions, the number of SARS-CoV-2 infections may be more than 10 times higher than the number of cases of new coronary pneumonia,” the researchers concluded. However, most people in each region may not be able to detect SARS-CoV-2 antibodies. “
Before today’s announcement, Redfield had been an outspoken predicter of the potential benefits and benefits of wearing a mask in the United States. The WHO Director-General said last week that the outbreak could be brought under control within four to eight weeks if everyone in the United States could be persuaded to wear masks.
In addition, Redfield added, “Today, we test more individuals than ever before and identify more asymptomatic individuals.” “Even so, it is still believed that most Americans have not been exposed to the new coronapneumonia, suggesting that measures to prevent the virus remain critical to controlling the pressures of health care.”
