The Directorate-General for Health and the National Institute of Health Doutor Ricardo Jorge makes available, Report no 6 dated, 22nd April, a Monitoring Report on the Epidemiological Situation of COVID-19, in order to guarantee the monitoring of the current epidemiological situation and prepare the transition to a later phase of recovery from the pandemic.
The Monitoring Report on the Epidemiological Situation of COVID-19 n.º 6 is attached at the bottom of the page, from which the following points stand out:
From the analysis of the different indicators, the epidemic activity of the SARS-CoV-2 infection / COVID-19 maintained a very high intensity and a stable trend. The pressure on the health services was small, so the system can accommodate an increase in demand for patients with COVID-19. The impact on all-cause mortality is reduced, even though COVID-19 specific mortality is above the reference value defined by the European Centre for Disease Prevention and Control (ECDC). Surveillance of the epidemiological situation of COVID-19 should be maintained and individual protection measures and booster vaccination should be recommended.
- The cumulative number of new SARS-CoV-2 infection / COVID-19 cases per 100 000 inhabitants over the last 7 days was 583 cases, reflecting a nationally stable trend. The Norte region presented an increasing trend, the Centro region presented a stable trend and the remaining regions presented decreasing trends.
- The effective reproduction number (R(t)) was at 1 at national level (1.00) and above in Norte, Centro and Alentejo regions, indicating possible increasing trends in these regions.
- The number of COVID-19 cases admitted to Intensive Care Units (ICU) in mainland Portugal showed a decreasing trend, corresponding to 18.0% (23.5% in the previous analysis period) of the defined critical value of 255 occupied beds.
- The ratio between the number of hospitalized cases and notified infections was 0.18, presenting an increasing trend. This value is lower than those observed in previous pandemic waves indicating a lower seriousness of disease than observed in previous waves.
- The BA.2 lineage of Omicron variant reveals an estimated relative frequency of 94.4% on April 18th, 2022. It is highlighted the introduction and increase of circulation of the BA.5 lineage of Omicron variant, which presents some additional mutations associated with human cell binding and/or immune evasion.
- The COVID-19 specific mortality (27.9 deaths per 1 000 000 inhabitants over the last 14 days) maintained a stable trend. Mortality from all causes is within the expected values for this time of the year, which indicates a reduced impact of the pandemic on all-cause mortality, despite the value of specific mortality by COVID-19 being above the threshold defined by the ECDC.
