CDC Says 35% of Coronavirus Patients Are Asymptomatic The Centers for Disease Control and Prevention (CDC) also estimates that 40% of transmissions occur before a patient feels sick.
The agency says its estimates are based on real data but are subject to change.
The numbers are being used by “mathematical modelers throughout the federal government” to lay out five planning scenarios.
In the CDC’s "current best estimate ... in the United States," roughly 0.4% of people who feel sick will die from the novel coronavirus.
The CDC has emphasized that the mortality rates are strictly for advancing “public health preparedness and planning.”
