Navigating “Corona” rules: As in the United States, Germany’s states have different coronavirus protocols and social norms. If you travel throughout the country, expect the rules to shift. Remember, too, that protocols can change rapidly, depending on local infection rates. In general, regulations relating to the coronavirus — called “Corona” in Germany — remain stricter than those in the United States. Unless you’re renting a private house and sticking to outdoor spaces when sightseeing, expect to see these three words a lot: “geimpft, getestet, genesen.” They translate to “vaccinated, tested, recovered.” You must meet one of these criteria to dine indoors at many restaurants and participate in some indoor attractions.
