The incidence rate of SARS-CoV-2 infections per 100,000 inhabitants on the mainland rose today to 346.5, but the transmissibility index (Rt) fell again slightly to 1.15 on the mainland.
In the joint epidemiological bulletin of the Directorate-General of Health and the National Institute of Health Doutor Ricardo Jorge, it is noted that the incidence rate on the mainland rose from 325.2 where it was last Monday.
At a national level, this indicator rose from 315.6 to 336.3.

Data on Rt and incidence of new cases per 100,000 inhabitants at 14 days - indicators that make up the pandemic monitoring risk matrix - are updated by health authorities on Mondays, Wednesdays and Fridays.
In low population density counties, which represent more than half the mainland territory, the red line that forces municipalities to retreat in the deconfinement plan is fixed at 480 cases per 100 thousand inhabitants in the last 14 days and the remaining counties will be under alert when they exceed 240 cases per 100 thousand inhabitants in the same period.
