According to the document from the regional health authorities, there were eight active outbreaks in schools, which had 88 cases of infection by the new SARS-CoV-2 coronavirus, most of them in the Padre Cabanita 2nd and 3rd cycle primary school, in Loulé (29 cases), and in the Areal Gordo 1st cycle primary school and kindergarten, in Faro (21).

In workplaces, 10 active outbreaks were counted, four of which were in hotels, and a total of 50 confirmed cases of Covid-19 were recorded until Sunday in companies in Albufeira, Loulé, Portimão, Lagos, Olhão and Tavira.

Parties and social gatherings in the Algarve have led to five outbreaks of Covid-19, with 51 people infected, 10 of which were at a get-together on Ilha da Culatra, in Faro, while there were also outbreaks at restaurant gatherings in Loulé, Olhão and Lagos.

On Monday, more than 1,300 pupils from 52 classes in the five Algarve municipalities had face-to-face classes suspended and were in isolation, Algarve health delegate Ana Cristina Guerreiro told Lusa.

The decision to switch to online teaching until the end of the school year at 1st and 2nd cycle schools in the central Algarve municipalities - Faro, Loulé, Albufeira, Olhão and São Brás de Alportel - was announced late on Sunday afternoon due to the epidemiological "gravity of the situation".

In a family context, four outbreaks were identified, with 27 infected, and in homes and residential structures for the elderly, there was one outbreak, at the Torre Natal home in Faro, which accounted for 20 cases and one death - of an elderly woman aged 92.

Amongst sports teams, there were two outbreaks, in the Boliqueime hockey team (two cases) and in a basketball team in Olhão (five).

In nurseries, only one outbreak was identified, with two cases, in a kindergarten in Monte Gordo (Vila Real de Santo António). The 32 outbreaks had caused, until Sunday, one death and two hospitalisations.

The Algarve region has the highest transmissibility index (Rt) of the SARS-CoV-2 virus in the country, with 1.3, according to data released by the National Institute of Health Doutor Ricardo Jorge (INSA) on Friday.

Nationally, from 14 to 20 June, the Rt decreased from 1.20 to 1.1, which was also observed in Lisbon and Tagus Valley, but in the Algarve there was a "sharp increase" in the transmissibility index, which went from 1.07 on May 27 to 1.4 on June 14 (0.33 in 19 days).
