Every country has its own scale, so we ask them all the same question: is the whole country advised against?
An advisory covering only areas of the country does not raise the answer: it stays “No”, and the area is shown in the relevant column.
The level shown on this page — and across this site — is the one published by the U.S. State Department, from 1 (normal precautions) to 4 (do not travel). France and the United Kingdom publish their own advisories, with their own rules: they add to that level, they do not replace it.
