JENA, GERMANY - APRIL 03: A customer in a pharmacy in downtown Jena, wearing a protective face mask on April 3, 2020 in Jena, Germany. A three-part city ordinance is going into effect requiring people to wear protective face masks under circumstances that include shopping, riding public transport and workplaces where social distancing is difficult. A face mask requirement is a current issue of controversy across Germany, with the federal government so far declining to make wearing one in public mandatory. Germany is struggling with a shortage of face masks, and the requirement in Jena also allows the use of scarves and other materials to shield one's face as a means to reduce the risk of anyone infected with Covid-19 from infecting others.
