THE number of winter vomiting bug cases has fallen dramatically, writes Anne-Marie Walsh.
Just weeks after the norovirus was claiming thousands of new victims, latest figures show there has been a drastic drop in laboratory-confirmed cases.
Numbers fell from 130 confirmed cases in the second week of December to 67 the following week, and just 29 cases last week.
However, the figures mask the true extent of the illness as most cases are not reported.
British scientists believe that for every one case confirmed in a laboratory, there are 288 further patients affected, who are not confirmed cases.
Dr Paul McKeown, specialist in Public Health Medicine for the HSE, said it was normal for the norovirus to wane "during a period of upsurge".
He issued a word of warning however, saying people may have delayed going to their doctor over Christmas.
