This map is to be published once a week and takes into account two indicators: the number of positive cases in the last 14 days per 100,000 inhabitants and the percentage of tests done that gave positive results.

It categorises regions in three colours, green, orange and red, from lowest to highest risk.

Four of seven Portuguese regions, the North, Centre, Algarve and Lisbon and Tagus Valley regions, have been categorised as ‘red’, along with regions in 12 other European countries.
