Research – Norovirus GII.17 as Major Epidemic Strain in Italy, Winter 2015–16

CDC 

In winter 2015–16, norovirus GII.17 Kawasaki 2014 emerged as a cause of sporadic gastroenteritis in children in Italy. Median patient age was higher for those with GII.17 than GII.4 infection (55 vs. 24 months), suggesting increased circulation of variant Kawasaki 2014 among children and limited cross-protection for older children.
