US President Donald Trump has asked all Americans to wear face coverings, after warning that the outbreak in the United States may "get worse before it gets better". We chart the different ways the president has spoken about the issue in the past few months. We'll get one of our White House reporting team to explain the politics behind it, as well as telling us about her exploration of attitudes to masks in the state of Kansas. And we'll introduce you to Bobbi and James, Americans on either side of the face covering divide.

We'll get more of your questions answered on the coronavirus pandemic with our regular expert - today, Dr Maria Sundaram from ICES Ontario. Send your question on WhatsApp: +447730751925 or Twitter @bbcworldservice.

And we'll take you to an ICU in Pakistan where our team from 蜜芽传媒 Urdu has gained rare access to see how Covid-19 patients are being treated there.
