The head of Germany’s disease control agency says there are too many loopholes in the country’s coronavirus lockdown rules. Official figures published Thursday showed the country had the highest single-day number of deaths since the start of the pandemic — 1,244. Lothar Wieler of the Robert Koch Institute said data indicated people are traveling more now than during the first phase of the pandemic, contributing to the virus’ spread. German authorities have restricted social contacts, largely closed schools and limited travel in areas with high infection rates, but the rules aren’t uniformly enforced across the country’s 16 states. German officials are considering imposing tougher restrictions to curb the steep rise in infections.
