US Centers for Disease Control: 40% of people infected with New Coronavirus have no symptoms

CNN reported on July 11 that the US Centers for Disease Control and Prevention recently updated its guidelines for public health officials and mathematical modeling researchers. The guideline estimates that 40% of people infected with new coronavirus have no symptoms.

The US Centers for Disease Control and Prevention released five "COVID-19 Outbreak Planning Programs" in May, using data to predict a series of possible situations for the United States. The updated plan is based on new data collected by the agency before June 29. The agency also emphasized that these estimates may change as more information is obtained.

According to the agency’s “current best estimate”, 40% of patients infected with the new coronavirus have no symptoms, which is higher than the estimated 35% on May 20. The agency also announced the infection death rate. In the "best estimate" scenario, the infection mortality rate is 0.65%, which means that 0.65% of patients infected with the new coronavirus will die. The agency warned that "because asymptomatic cases are difficult to identify, and transmission is difficult to observe and quantify, there is still a high degree of uncertainty."
