Impact of the COVID-19 Pandemic on the Use of Quaternary Ammonium Compound Disinfectants in Healthcare Facilities Within Selected States in the United States of America.

Introduction Quaternary ammonium compounds (QACs) are the active ingredient in the majority of disinfectants approved for use against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), the causative agent of the coronavirus disease 2019 (COVID-19). Although widely used, they have been linked to infertility and birth defects in animals, and have been shown to increase proinflammatory cytokines, decrease mitochondrial function, and disrupt sterol biosynthetic pathways in a dose-dependent manner in humans. This study examined if there was an increased use of QAC-based disinfectants among healthcare settings in response to the COVID-19 pandemic and aims to bring to light the negative health outcomes that this rise in QAC exposure may pose.

Mutagenesis studies suggest a mechanism for influenza polymerase stalling during polyadenylation.

Influenza polymerase (FluPol) carries out both viral transcription and replication using the same viral genome segment as a template to yield distinct end products. However, it remains largely unclear how FluPol synthesizes transcripts containing poly (A) tails during transcription termination, while producing fully complementary products during replication termination. In this study, through structural analysis combined with cell-based and biochemical assays, we identified that the PB1 Leu675/Asn676 and PB2 Arg38 residues of FluPol are critical for transcription termination and polyadenylation.
