The HSE has reported a spike in noravirus cases since the beginning of the year.
Noravirus, which is commonly known as the winter vomiting bug, is one of the most common stomach bugs in Ireland. Besides vomiting, it can also cause diarrhoea and fever.
The HPSC recorded 394 cases of the illness over the past 10 weeks in Ireland. The numbers are almost four times higher than the number of cases reported in the first 10 weeks of 2022, with just 109 cases of noravirus reported.
