The latest subvariant of the Omicron strain of the coronavirus is as harmful to the lungs as the previous Delta variant although it still mainly attacks only the most vulnerable groups -- the unvaccinated and the under-vaccinated -- says an expert from Siriraj Hospital.
Among people currently receiving Covid-19 treatment, about 800 are suffering from lung infections which account for about 8% of all Covid-19 hospitalisations, says Dr Nithipat Jearakul, head of Siriraj Hospital's Department of Respiratory Disease and Tuberculosis within the Department of Internal Medicine at the Faculty of Medicine.
