According to the report, the centers say that 40 percent of HIV transmission occurs before people feel sick.
The agency cautioned that these figures are subject to change as more is known about Covid-19, and also warned that the information is intended for planning purposes.
The agency says its estimates are based on real data it collected before April 29.
The report notes that the numbers are part of five planning scenarios that are used by mathematical modeling throughout the federal government, according to the CDC.
Four of these scenarios represent “the upper and lower bounds of disease severity and susceptibility to viral transmission”.
The fifth scenario, according to the report, is “the best current estimate of virus transmission and disease severity in the United States.”
In this scenario, the agency estimates that 0.4 percent of people who feel ill and have symptoms will die.
This percentage increases for people aged 65 years or over to reach 1.3 percent, while the percentage reaches 0.05 percent for people under the age of 49.
On Thursday, the US Centers for Disease Control and Prevention recorded 22,860 new infections, bringing the total number of cases to 1 million and 551,095, adding that the number of deaths increased by 1,397 to 9,3061.
