I call those individuals PRE- symptomatic, not asymptomatic, and yes, I know of several people personally who this held true for.
One young lady I know was exposed at her job. Someone tested positive so they all got tested. Her first test was negative. A day or two later, she began her earliest symptoms. She felt like she was getting a head cold, and then had no taste or smell a day later.
When her fiancé started with a headache, she was retested and this time was positive. Two days later he tested positive also.
Both are over it now, and got to spend a late Christmas with their families.
In my mind, this is pre-symptomatic not asymptomatic spread. I would love to know if I am wrong in this assessment.
I have a relative who got covid at work..The night before he
came down with symptoms, he had people over at his house..Four people who were at his house the night beforedid not get sick,
