Abstract

Norovirus GII.4 Sydney 2012 has spread globally since late 2012. We report hospitalization of patients infected with this strain skewed toward infants and young children among 174 cases during August 2012-July 2013 in Hong Kong, China. This group had higher fecal viral load (≈10-fold) than did older children and adults.

Keywords: China; GII.4 Sydney 2012; Hong Kong; hospitalization; infant; norovirus; viral burden; viral load; viruses.
