United States President Donald Trump surprised the world by wearing a mask in public for the first time since the outbreak of the novel Coronavirus (COVID-19) pandemic.
Trump had previously refused to wear masks in public, although he had said he would if in a crowd and could not maintain physical distance from others.
He had come under sharp criticisms even from his fellow Republican Party members, who said his stance showed lack of example or leadership.
He finally did that during a visit to the Walter Reed National Military Medical Centre outside Washington where he met wounded soldiers and frontline healthcare workers.
