pre-symptomatic
Before symptoms appear
Pre-symptomatic describes the period after infection or disease onset but before symptoms appear.
A pre-symptomatic person carries an illness and may be contagious, though they feel fine: Pre-symptomatic transmission made the virus difficult to contain.
The term gained prominence during COVID-19 discussions about spread from seemingly healthy individuals.
