China News Service, April 3, according to foreign media reports. Recently, Redfield, director of the Centers for Disease Control and Prevention (CDC), said in an interview with the National Public Radio (NPR) that 25% of new crown pneumonia infections in the United States People are asymptomatic, and the epidemic situation may continue to affect people's lives within 24 months.

Redfield said that the spread of new crown pneumonia is much easier than the flu, partly because the infected person can spread the virus for up to 48 hours before the body becomes unwell.
"This helps explain the speed at which the virus is spreading across the country, because we have asymptomatic spreaders, and patients are transmitting the virus for 48 hours before they develop symptoms," he said.
Currently, the new crown pneumonia virus is spreading rapidly in the United States. According to statistics from Johns Hopkins University in the United States, as of the 2nd local time, there have been more than 240,000 confirmed cases of new crown pneumonia in the United States, and nearly 6,000 people have died.
It is reported that because the scope of detection is not wide enough, it is currently unknown how many people have been infected with the virus. Currently, the U.S. federal government is urging people to maintain social distance, and multiple states have issued house orders to slow the spread of the virus.
"The social alienation policy we are pushing forward ... is a huge weapon that will accelerate the epidemic," Redfield said.
He also believes that the spread of new crown pneumonia will slow down at the end of spring or the beginning of summer, but the CDC is preparing for its second outbreak in autumn or winter.
In addition, Redfield also warned that in the next 24 months, the new crown virus is likely to continue to affect people's daily lives. He said that the most important thing is that people continue to maintain social distance and make prevention and quarantine work smoothly.
