Researcher at University of Leicester and member of the scientific committee that advises the Catalan Government on covid Salvador Macip talks to ARA by phone from the UK. Although the epidemiological situation has improved in Catalonia and Europe and it is expected that in the coming months the prevalence of covid will decrease, the scientist warns that there are too many infections to stop monitoring the virus altogether. Therefore, he defends minimally invasive measures, such as the use of masks indoors, should continue. This includes classrooms, where health authorities want to lift the mandate within ten days.
