Scotland is experiencing an increase in Covid-19 infections as cases of two Omicron variants rise, a public health expert has warned.
Professor Linda Bauld said the Omicron sub-lineages BA.4 and BA.5. are part of the reason for the increase in cases and a "small but not significant" rise in the number of people in hospital.
However, she said that vaccines are working well in the vast majority of people and are making a difference between the risk from infection and the risk of severe disease.
