(GermanPolicy.com) – The German Association of Cities has appealed to the Federal Government to take precautions as soon as possible with a view to a Corona wave that could occur in autumn. City day general manager Dedy said, according to media reports, that a new wave will certainly occur after this summer. It is possible that the mask requirement for retail purchases will therefore have to be reintroduced for a few months. To bring this about, it would be necessary to again amend the Infection Protection Act. The regulation would then apply nationwide.
