Influenza B Yamagata has accounted for 60%-70% of confirmed flu cases in Ireland so far.
While focus has been on the deadly Aussie Flu, Yamagata or' Japanese flu' has been silently spreading across the Country.
Yamagata is a subtype of Influenza B, while Aussie flu is type A.
This means that anyone who has been vaccinated against the Aussie Flu isn't protected from the Japanese Flu.
Dr Ben Coyle, the Medical Director from the Now Healthcare Group says it's generally more mild than A strains.
Speaking to the Expresss UK he said: “Yamagata also tends to affect mainly children and is much more contagious as a result because children spread viruses more easily than adults.''
Management is the usual - washing hands, covering mouth when coughing/sneezing, avoiding the at-risk, and using over the counter medicines like paracetamol for fever and other symptoms.”
