Key result
During the 2010-2011 seasonal epidemic, the unusual G12 genotype emerged rapidly and predominantly, causing 65% of rotavirus gastroenteritis cases in children under 3 years of age.
Observational (n=504)
Yes
The sudden emergence and predominance of the G12[P8] rotavirus genotype in northern Spain highlights its potential to become a major human rotavirus strain globally.
No takes yet. Share an insight, caveat, or question.
G12 predominance in young children supports intensified rotavirus strain surveillance; leaves open vaccine performance against emerging genotypes.
Cilla et al. (2012) conducted an observational in Acute gastroenteritis (Rotavirus infection) (n=504). Rotavirus G12 genotype vs. Other rotavirus genotypes (e.g., G1, G9) was evaluated on Proportion of rotavirus gastroenteritis cases caused by the G12 genotype during the 2010-2011 epidemic. During the 2010-2011 seasonal epidemic, the unusual G12 genotype emerged rapidly and predominantly, causing 65% of rotavirus gastroenteritis cases in children under 3 years of age.
