The number of additional deaths from the coronavirus is relatively small in Germany. According to figures, an average of 8 percent more people died than usual in a given period.
The researchers compared a week in April with death rates from the past four years.
At least 18,693 people died in the Federal Republic between April 13 and 19, 8 percent more than in the years 2016 to 2019.
Because the latest flu wave has ended since mid-March, the scientists blame the increase on the corona epidemic.
By comparison, Italy reported nearly 50 percent more deaths in March than average in the years 2015 to 2019.
