The question of whether further restrictions should be introduced is constantly under review, the chief medical officer told an online news briefing. Cecilía Müller said the effectiveness of measures enacted Nov. 11 would be visible in two weeks’ time. She also said a new government programme to test people working in social, health, education and training institutions was a logistical challenge but the system was up to the task. Regarding seasonal flu, Müller said that in week 46, 9,700 people consulted their doctor with flu-like symptoms, but no flu virus has been found in samples tested in laboratories.
