First Minister, on 20 March, the Royal College of Surgeons recommended that anosmia, the loss of a sense of smell, should be added to the list of COVID-19 symptoms, and that was discussed by the Scientific Advisory Group for Emergencies on 24 March. A paper for SAGE on 16 April confirmed that the loss of smell and taste was a strong predictor of infection. Why did it take until Monday of this week for you to change the guidance to the public? And do you accept that people who should have been self-isolating haven't been doing so because of this delay?
