As Covid infections rise, an expert has warned of an Omicron sub-variant symptom that affects people at nighttime.
Professor Luke O'Neill of Trinity College spoke about the latest increase in cases and the BA.5 variant on Newstalk.
"One extra symptom for BA.5 I saw this morning is night sweats - isn't that strange?" said the immunologist on the Irish radio station. "So the disease is slightly different because the virus has changed."
