It takes more than just wearing a mask, or just “social distancing”. The 6 feet are not a hard and fast rule, that’s if you’re not talking yelling etc, and if you have good ventilation. If you have no ventilation, you need more than 6 feet.
An naked mouth, shouting, spits as far as coughing in someones face. 20 something feet.
Hands, face, space, and ventilation.
Don’t feel like you’re doing proper and get uppity based on one line from the CDC, who is usually in disagreement with the rest of the world or is always too late with the info.
