Chancellor Angela Merkel and the governors of Germany’s 16 states were conferring Tuesday on how to prevent the country’s coronavirus infection figures from accelerating to the levels being seen in other European countries, and new restrictions were possible. New infections in Germany have hit the highest levels since April in recent weeks, with more than 2,000 new cases per day on several occasions. Infection rates in Munich and some other cities have recently hovered around the mark of 50 new cases per 100,000 residents a week, a level that requires authorities to take action.
