Both the R-value of 1.18 and the 7-day incidence of 75.19 give the Portuguese authorities current cause for concern (as of June 21). The corona situation was considered under control for months. The reason for the sharp increase is the spread of the delta variant of the virus, especially in the greater Lisbon area: This accounted for more than 60 percent of the new corona cases recorded last weekend. For this reason, the authorities had decided to partially cordon off the capital region from Friday to Monday morning.
