Swiss officials who banned travel from Britain and South Africa on Monday on fear of mutant coronavirus variants that are spreading rapidly in those countries believe a new strain is likely already in Switzerland, despite not having detected it, Reuters reported. The Swiss government, among nations to levy travel restrictions, ordered people who have entered the country from the United Kingdom and South Africa since Dec. 14 to undergo a 10-day quarantine and imposed a general entry ban for foreign nationals from the countries.
