Germany on Friday declared the whole of France a "high risk" area for coronavirus infections, a move that means travellers need to show a negative Covid test and quarantine upon arrival. France, including all French overseas departments, are now considered "at particularly high risk of infection due to a particularly high number of cases", Germany's Robert Koch Institute for infectious diseases said. Slovakia and the Czech Republic were meanwhile downgraded from the highest alert red list of "virus variants regions" to "high risk" areas. mfp/hmn/har
