50
The so-called incidence is considered an important benchmark in the fight against a pandemic. The seven-day incidence indicates the number of new infections within the past seven days per 100,000 inhabitants. The 14-day incidence is used to better represent long-term trends.
In Germany, for example, the permissible upper limit has so far been 50 new infections per 100,000 inhabitants within a week. In Austria, such a limit is not precisely defined. In the Corona traffic light, a region is set to red if there is a “high 7-day cumulative incidence relative to population size”.
