Characterization and evolutionary #history of novel #SARS-CoV-2-related #viruses in #bats from #Cambodia

Abstract Circulating bat coronaviruses present a significant pandemic threat, yet our  understanding of  their genetic diversity and evolutionary dynamics remains limited.  Over 3 years, we sampled  1,462 bats in Cambodia’s Steung Treng province,  identifying extensive and diverse  coronaviruses co-circulation. Using  metatranscriptomic and amplicon sequencing, we  generated 33 complete  sarbecovirus genomes, revealing novel lineages that cluster into four  distinct  groups, each associated with different Rhinolophus bat species. Our analysis  highlights rapid migration and recombination of sarbecovirus lineages over  short distances  and timescales. Of note, the receptor-binding domains of two novel  viral groups exhibit high  similarity to SARS-CoV-2, and pseudovirus assays  confirmed the ability of this spike protein  to mediate entry into cells expressing  human ACE2, suggesting a potentia...

#Cardiovascular post-acute #sequelae of #SARS-CoV-2 in #children and #adolescents: cohort study using electronic health records

Abstract The risk of cardiovascular outcomes following SARS-CoV-2 infection has been reported in adults , but evidence in children and adolescents is limited . This paper assessed the risk of a multitude of cardiac signs, symptoms, and conditions 28-179 days after infection , with outcomes stratified by the presence of congenital heart defects (CHDs), using electronic health records (EHR) data from 19 children’s hospitals and health institutions from the United States within the RECOVER consortium between March 2020 and September 2023. The cohort included 297,920 SARS-CoV-2-positive individuals and 915,402 SARS-CoV-2-negative controls. Every individual had at least a six-month follow-up after cohort entry. Here we show that children and adolescents with prior SARS-CoV-2 infection are at a statistically significant increased risk of various cardiovascular outcomes, including hypertension, ventricular arrhythmias , myocarditis, heart failure, cardiomyopathy, cardiac arrest, thromboemboli...

A #coronavirus assembly #inhibitor that targets the viral #membrane protein

Abstract The coronavirus membrane protein (M) is the main organizer of coronavirus assembly. Here, we report on an M-targeting molecule , CIM-834, that blocks the assembly of SARS-CoV-2. CIM-834 was obtained through high-throughput phenotypic antiviral screening followed by medicinal-chemistry efforts and target elucidation. CIM-834 inhibits the replication of SARS-CoV-2 (including a broad panel of variants) and SARS-CoV. In SCID mice and Syrian hamsters intranasally infected with SARS-CoV-2, oral treatment reduced lung viral titres to nearly undetectable levels, even (as shown in mice) when treatment was delayed until 24 h before the end point. Treatment of infected hamsters prevented transmission to untreated sentinels. Transmission electron microscopy studies show that virion assembly is completely absent in cells treated with CIM-834. Single-particle cryo-electron microscopy reveals that CIM-834 binds and stabilizes the M protein in its short form, thereby preventing the conformati...

Quantifying #viral #pandemic #potential from experimental #transmission #studies

Abstract In the past two decades, two pandemic respiratory viruses (H1N1 and SARS-CoV-2) have emerged via spillover from animal reservoirs . In an effort to avert future pandemics, surveillance studies aimed at identifying zoonotic viruses at high risk of spilling over into humans act to monitor the `viral chatter' at the animal-human interface . These studies are hampered, however, by the diversity of zoonotic viruses and the limited tools available to assess pandemic risk. Methods currently in use include the characterization of candidate viruses using in vitro laboratory assays and experimental transmission studies in animal models . However, transmission experiments yield relatively low-resolution outputs that are not immediately translatable to projections of viral dynamics at the level of a host population. To address this gap, we present an analytical framework to extend the use of measurements from experimental transmission studies to generate more quantitative risk assessm...

Post-pandemic #changes in #population #immunity have reduced the likelihood of emergence of #zoonotic #coronaviruses

Abstract Infections caused by endemic viruses , and the vaccines used to control them, often provide cross-protection against related viruses. This cross-protection has the potential to alter the transmission dynamics and likelihood of emergence of novel zoonotic viruses with pandemic potential. Here, we investigate how changes in population immunity after the COVID-19 pandemic have impacted the likelihood of emergence of a novel sarbecovirus , termed SARS-CoV-X. We show that sera from patients with different COVID-19 immunological histories possess cross-neutralising antibodies against the spike (S) protein of multiple zoonotic sarbecoviruses . Mathematical simulations using these viruses show a significant reduction in their likelihood of emergence in populations with current levels of SARS-CoV-2 natural and vaccine-derived immunity, with the outcome determined by the extent of cross-protection and the R_0 of the novel virus. We also show that preventative vaccination programs agains...
