According to the weekly report of the Dr. Ricardo Jorge National Institute of Health (INSA) on the evolution of the covid-19 pandemic curve, only Madeira has an Rt index – which estimates the number of secondary cases of covid-19 caused by an infected person – – below the specified limit of 1, and now stands at 0.83.
Lisbon and Vale do Tejo is the region of the country with the highest Rt, having gone from 1.14 to 1.16 within a week, while Alentejo has reduced its transmission rate from 1.16 to 1.01.
According to the INSA report, the North, the Algarve and the Central have RT 1.04 and the Azores 1.05. According to the institute’s data, between May 2 and May 30, there was an increase in Rt from 0.91 to 1.07 in the country, indicating a “transition from a decreasing trend to an increasing trend in the incidence of SARS-CoV-2”.
“This difference was more pronounced in the Lisbon region and the Valle do Tejo, where Rt moved from 0.88 on April 30 to 1.22 on May 17,” and later dropped to 1.15 on May 30.
In terms of the cumulative incidence of new cases in 14 days, the Azores is the only region in the country to exceed the benchmark 120, with a rate of 146.6.
Lisbon and Vale do Tejo have their cumulative infection rate of new cases, which rose from 68.1 to 92.7, with Madeira showing the largest drop, from 109.7 to 76.3.
The North, Central and Alentejo regions have a 14-day cumulative infection rate of less than 60 cases per 100,000 population.
The country offers “a cumulative notification rate of 14 days between 60 and 119.9 per 100,000 inhabitants and an Rt of greater than 1, i.e. a moderate notification rate with an increasing trend”, says INSA, adding that, at the European level, “in the UK it is the same case Portugal”.
These two indicators – the virus susceptibility index and the infection rate of new COVID-19 cases – are the criteria set by the government for the ongoing assessment of the dismantling process that began on March 15 and is currently underway. In the fourth phase of easing restrictions.
In Portugal, 17,029 people died out of 851,031 confirmed cases, according to the latest bulletin issued by the Directorate General of Health.
The disease is transmitted by the new coronavirus, SARS-CoV-2, which was discovered in late 2019 in the central Chinese city of Wuhan.
