This article reports the changes to virus taxonomy approved and ratified by the International Committee on Taxonomy of Viruses (ICTV) in February 2019. Of note, in addition to seven new virus families, the ICTV has approved, by an absolute majority, the creation of the realm Riboviria, a likely monophyletic group encompassing all viruses with positive-strand, negative-strand and double-strand genomic RNA that use cognate RNA-directed RNA polymerases for replication.

In temperate regions, respiratory viruses such as SARS-CoV-2 are better transmitted in winter than in summer. Understanding how the weather is associated with SARS-CoV-2 transmissibility can enhance projections of COVID-19 incidence and improve estimation of the effectiveness of control measures. During the pandemic, transmissibility was tracked by the reproduction number .

In addition to the more famous canine parvovirus 2 (CPV-2), the Parvoviridae family includes other viruses able to infect dogs [canine chaphamaparvovirus (CaChPV), canine bocavirus-1 (CBoV-1), and canine bufavirus (CBuV)], whose etiological role is still controversial (mostly identified in animals with diarrhea but also detected in asymptomatic animals). The aim of this work was to evaluate the shedding of these common and recently discovered viruses in the dog population from the Campania region (Italy). A total of 170 feces from apparently healthy dogs were sampled and tested with specific real-time PCR.

Background: Hepatitis C virus (HCV) and injection drug use among young women are dramatically rising in the rural United States. From 2004 to 2017, heroin use among non-pregnant women increased 22.4% biennially, mirroring increases in HCV cases, especially among younger populations.

Background: The SARS-CoV-2 virus has evolved subvariants since the emergence of the omicron variant in 2021. Whether these changes impact viral shedding and transmissibility is not known.
Methods: POSITIVES is a prospective longitudinal cohort of individuals with mild SARS-CoV-2 infection.

In cardiovascular research, melatonin has shown promise in exhibiting antifibrotic properties and modulating endoplasmic reticulum (ER) stress. However, the exact mechanism by which it influences myocardial fibrosis has not been fully clarified. Therefore, this research aimed to investigate the inhibitory effect of melatonin on the progression of myocardial fibrosis through a mechanism involving the BIP/PERK/CHOP signaling pathway, both in silico and in vivo experimental models.
