The classification system rates travel to each country as low (green), high (yellow), or very high risk (red). No countries are currently ranked as very high risk.
Only six EU/EEA countries are currently rated green: Romania, Slovakia, the Czech Republic (incorrectly listed as Slovakia for a second time in the English language list), Poland, Hungary and the Vatican.
"Yellow list" countries are those in which the 14-day cumulative number of COVID-19 cases per 100,000 inhabitants exceeds 75.
The epidemiological requirements based upon the lists come into force at midnight, i.e. 00:00 on Saturday, September 4.
The latest list of countries, their current travel status, and the necessary epidemiological measures that apply is available HERE and is also attached to this story in PDF form.
