he Directorate-General for Health (DGS) and the National Institute of Health Doutor Ricardo Jorge (INSA) release report No. 19 dated 22nd July 2022 on monitoring the epidemiological situation of COVID-19. The document includes several indicators, namely the seven-day incidence and the transmissibility index (R(t)), nationally and by health region, among others.
The COVID-19 epidemic maintains a very high incidence, although with a decreasing trend. The impact on hospitalizations shows a decreasing trend, as well as specific mortality by COVID-19. It is expected that the demand for health care will continue to decline. Surveillance of the epidemiological situation of COVID-19 should be maintained, recommending the maintenance of individual protection measures, booster vaccination and frequent communication of these measures to the population.
The following points are also highlighted in this document:
- The number of new cases of infection by SARS-CoV-2 / COVID-19, per 100,000 inhabitants, accumulated in the last 7 days, was 349 cases, with a decreasing trend nationally and in all regions;
- RT(t) transmission rate presented a value lower than 1 at the national level and in all regions, which indicates a decreasing trend of new cases;
- The number of people with COVID-19 hospitalized in Intensive Care Units (ICU) on the continent showed a decreasing trend, corresponding to 19.2% (in the previous period under analysis it was 22.4%) of the defined critical value of 255 beds. busy;
- The ratio between the number of hospitalized and infected people was 0.16, indicating a lower severity of the infection, similar to what has been observed since the beginning of 2022;
- The BA.5 lineage of the Omicron variant remains clearly dominant in Portugal, with an estimated relative frequency of 95% at week 27 (04/07/2022 to 10/07/2022). This strain has shown a greater capacity for transmission, which is potentially mediated by additional mutations that impact the entry of the virus into human cells and/or its ability to evade the immune response;
- Specific mortality from COVID-19 (23.5 deaths in 14 days per 1,000,000 inhabitants) shows a decreasing trend. All-cause mortality is above the upper limit of the expected value for the time of year, indicating an excess of all-cause mortality, in part associated with COVID-19-specific mortality.
