Enterovirus D68 (EV-D68), a serotype of the enterovirus species D, has garnered significant attention due to outbreaks reported in 2014, 2016, and 2018. In this study, 36 Chinese EV-D68 strains were isolated, sequenced, and combined with all EV-D68 VP1 sequences from GenBank to form a data set of 1679 sequences. This data set served as the basis for phylogenetic, evolutionary dynamics, phylogeographic, and key amino acid site mutation analyses of EV-D68. Based on the VP1 region, EV-D68 is classified into four genotypes (A-D), and seven subgenotypes (B1-B3, D1-D4), with B3 and D3 being the predominant subgenotypes. Bayesian skyline plots indicated that genotypes B and D experienced multiple population expansions, aligning with reported EV-D68 outbreaks. Phylogeographic analyses of the B3 subgenotypes revealed sequences from Europe and North America clustering into a single evolutionary branch, suggesting significant transmission between these regions. Additionally, mutation analysis identified VP1-98 as a high-frequency mutation site, differing significantly between the previously prevalent A and C genotypes and the currently prevalent B and D genotypes. However, the functional implications of this mutation require further investigation. This study provides a solid theoretical basis for epidemiological research, disease surveillance, and prevention efforts related to EV-D68.

The case of fatal course of rotaviral gastroenteritis at eight months old boy has been described. Two days history of frequent watery stools in home care, hyperosmolar dehydration grading to hypovolemic shock, cardiopulmonary resuscitation in regional hospital, transported comatose with vital functions support. In spite of temporary stabilization of the patient, there was retrogression to multiorgan failure (ischemic myocardial infliction, circulatory failure, ARDS, renal failure, DIC, enteritis, post ischemic hepatopathy). Four day later patient exits. Rotaviruses have been proved from stools specimen post mortem.
