Germany will require people arriving from countries deemed high risk, such as the United States, to take coronavirus tests starting this weekend, the health minister said Thursday, as the country recorded its highest daily tally of new infections in three months.

German officials have voiced alarm over a steady upward creep in the new infections over recent weeks. The national disease control centre, the Robert Koch Institute, said 1,045 cases were recorded on Wednesday — the first time since May 7 that it has counted more than 1,000 new cases in a day.
