CDC estimates that 35% of coronavirus patients don’t have symptoms
According to the most recent CDC data, roughly 1 in 3 people who become infected with COVID-19 are asymptomatic. Of people who display symptoms, about 0.4% (about 1 in 250) will die. For people over age 65, 1.3% (about 1 in 77) will die.

The CDC also says its “best estimate” is that 0.4% of people who show symptoms and have Covid-19 will die, and the agency estimates that 40% of coronavirus transmission is occurring before people feel sick.
The agency cautions that those numbers are subject to change as more is learned about Covid-19, and it warns that the information is intended for planning purposes. Still, the agency says its estimates are based on real data collected by the agency before April 29.
The numbers are part of five planning scenarios that “are being used by mathematical modelers throughout the federal government,” according to the CDC. Four of those scenarios represent “the lower and upper bounds of disease severity and viral transmissibility.”
The fifth scenario is the CDC’s “current best estimate about viral transmission and disease severity in the United States.” In that scenario, the agency described its estimate that 0.4% of people who feel sick with Covid-19 will die.
For people age 65 and older, the CDC puts that number at 1.3%. For people 49 and under, the agency estimated that 0.05% of symptomatic people will die.
