Norovirus (NoV) is an important etiological agent of diarrhea in children and adults. In Mexico, NoV screening is not routinely performed. NoV is highly infectious and is responsible for massive outbreaks due to the consumption of contaminated food. The study was a cross-sectional design. Samples of diarrheal stools were collected from (62) children and (38) adults with acute gastroenteritis during 2013–2014. The circulating genogroups of NoV were detected by amplifying the RdRp gene fragment, and for the genotyping, the capsid and polymerase fragments were sequenced. Seventy-seven percent of the analyzed samples were positive for NoV. Genotyping was possible for 51 samples; for polymerase GII.P2, GII.P31, GII.P4, GII.P7, GII.P40, and GI.P14 were identified, whereas for capsid, genotypes GI.3, GII.2, GII.4, GII.5, GII.14, and GII.17. In conclusion, there is a high prevalence of gastroenteritis due to NoV in the northwest of Mexico, including genotypes that have not been reported previously in Mexico.
