For the second week in a row, the delta variant of the new coronavirus was responsible for 100% of new infections in all regions of Portugal.
The information is part of the latest SARS-CoV-2 genetic diversity report published this Tuesday (31) by the National Health Institute Dr. Ricardo Jorge, which analyzed positive cases identified between August 16 and 22.
Periodic monitoring of coronavirus strains carried out by the Portuguese authorities has shown how this variant, first identified in India, became dominant in the country. Portugal identified the first cases of this strain in April.
The spread of the delta began in the greater Lisbon region, but quickly spread throughout the country, being also dominant in the autonomous regions of the Azores and Madeira.
Two other variants that came to be a source of alert for Portuguese authorities, beta (first identified in South Africa), and gamma (associated with Manaus, Brazil) were not identified in any of the samples analyzed in the last two weeks.
The emergence of the delta variant caused an increase in cases in Portugal and even led to a setback in the country’s reopening process, with the re-implementation of some restrictive measures.
The high vaccination coverage in the country, however, ensured that the number of deaths and hospitalizations did not follow the rise in infections.
With more than 73% of the population completely immunized, the country has already resumed –and even advanced the schedule– the end of restrictions linked to the pandemic.
