Face mask mandates prove effective but politically controversial

BERLIN, GERMANY - APRIL 22: A surgical mask and an N95 mask hang on display for sale at a pharmacy during the novel coronavirus crisis on April 22, 2020 in Berlin, Germany. Germany is taking its first steps to ease restrictions on public life that had been imposed weeks ago in order to stem the spread of the coronavirus. Shops across the country are reopening, factory assembly lines are restarting and high schools are holding final exams. Health leaders are monitoring the process carefully for any resurgence of coronavirus (Covid-19) infections. The number of infections nationwide is still rising, though so far at a declining rate.
