Human rhinovirus (RV) most often causes mild upper respiratory tract infection. Although RV is routinely isolated from the respiratory tract, few studies have examined RV in other types of clinical samples. The prevalence of RV was examined in 1,294 stool samples collected mostly from children with acute gastroenteritis residing in Bangkok and Khon Kaen province of Thailand between January 2010 and October 2014. In addition, 591 samples from hand-foot-mouth disease (HFMD) or herpangina patients who do not have gastroenteritis served as a comparison group. Samples were initially screened by semi-nested PCR for the RV 5'UTR through the VP2 capsid region. RV genotyping and phylogenetic analysis were performed on the VP4/VP2 regions. Among children with acute gastroenteritis, RV was found in 2.3% (30/1,294) of stool samples, which comprised 47% (14/30) RV-A, 17% (5/30) RV-B, and 37% (11/30) RV-C. In the comparison group, 0.8% (5/591) was RV-positive and RV-C (3/5) was the major species found. Interestingly, RV was recovered more often from children with acute gastroenteritis than from those with HFMD or herpangina. As many as 31 RV types were present in the gastroenteritis stools, which were different than the types found in those with HFMD or herpangina. J. Med. Virol. 89:801-808, 2017.
