Restrictions to continue!

[Wao nahele kane]

CDC original recommendation was actually 10’.


There are ideal circumstances.  There are real world circumstances. 

Think about 10' spacing in lines and in stores.  It would be difficult to observe, and when that's the case the restriction is more likely to be ignored.  6' is possible, it's more effective than no social distancing at all so it was probably deemed an acceptable compromise between the ideal and the realistic.

I recall reading that and along the way after they researched it more, they found that 3' was really no worse than 6 feet and 3' would have been optimal, but the 6 foot rule had already been adopted and implemented, so they stuck with 6'.
6' was adopted for practicality after the 10' foot was initially recommended.
