US President Donald Trump has announced new government recommendations for all Americans to wear masks when they go outside to help to stop the spread of the Covid-19.

Mr Trump told a White House press conference that the Centers for Disease Control and Prevention was urging people to wear any face covering, like scarves, but to keep medical-grade masks free for health workers.

In a daily briefing with reporters, Mr Trump stressed that the new recommendation should not be seen as replacing social distancing measures, considered key to slowing the outbreak.

"With the masks, it's going to be really a voluntary thing. You can do it, you don't have to do it. I'm choosing not to do it, but some people may want to do it and that's OK," said President Trump.
