CLEARLY one & ALL here are NOT advocating ie "wishing".
A large percent can be asymptomatic; "What does asymptomatic mean? The definition of asymptomatic means “presenting no symptoms of a disease”. Therefore, if a person contracts the coronavirus but is asymptomatic, they do not show any symptoms". https://www.merriam-webster.com/dictionary/asymptomatic
Which means, one may think they're fine but, perhaps not.
I'm SURE the intent was to possibly find asymptomatic people before they go into a public event.
TPTW is offering an on-site test to see if you have it before entering. That's the purpose of the mobile labs there, (current results in 15mins), in the first place.
