The head of virology at Son Espases University Hospital, Jordi Reina, says that 90% of Covid cases being sequenced at the hospital's microbiology lab are of the Omicron variant. Extrapolating from this, it can be concluded that 80 to 90 per cent of all cases in the Balearics are Omicron. Much more contagious than previous variants, but also less virulent, Reina adds that it has become dominant in the Balearics "very rapidly".
