While US health experts continue to encourage mask use in public, and more parts of the country adopt this guidance, there has been pushback from some Americans about covering up. Why?
Many protesters across the states have been pictured defying social distancing guidance without masks or face coverings. Online, the debate about mask effectiveness still plays out, with some claiming masks are not effective – or enforceable under US law.
This is in marked contrast to other countries where populations have generally been compliant in wearing face coverings.
