Update 2021-04-21: On Wednesday (21 April), the Bundestag passed the countrywide “emergency brake”. This is intended to standardise countrywide the restrictions that are to come into force at certain incidence levels. These include, for example, a night-time curfew between 10:00 p.m. and 05:00 a.m. (local time) and restrictions on contact to one person outside one’s household at a 7-day incidence above 100 cases per 100,000 population. Further details on the regulations can be found in the link below.
