Markers of community outbreak and facility type for mitigation of COVID-19 in long-term care homes in Ontario, Canada: insights and implications from a time-series analysis
CONCLUSIONS: The association between the risk of COVID-19 in the health region and the deaths among LTCH residents, and the delay between fatality among individuals residing outside and inside LTCHs suggests that fatality in a health region could be a predictor of outbreak in LTCHs within the same health region.PMID:37690739 | DOI:10.1016/j.annepidem.2023.08.005

Analytical tool for COVID-19 using an SIR model equivalent to the chain reaction equation of infection
Biosystems. 2023 Sep 8:105029. doi: 10.1016/j.biosystems.2023.105029. Online ahead of print.ABSTRACTInsights from data analysis of existing cases are important to prevent future outbreaks of coronavirus disease 2019 (COVID-19). Although mathematical models are expected to be useful for this purpose, the adequacy of reproducibility of these models is difficult to confirm because they are based on hypotheses. For example, using the time variation of the parameter of the basic reproduction number for the time variation of complex data on the number of infected persons is a change of expression and does not capture the substan...

Modelling norovirus dynamics within oysters emphasises potential food safety issues associated with current testing & amp; depuration protocols
Food Microbiol. 2023 Dec;116:104363. doi: 10.1016/j.fm.2023.104363. Epub 2023 Aug 18.ABSTRACTNorovirus is a significant global cause of viral gastroenteritis, with raw oyster consumption often linked to such outbreaks due to their filter-feeding in harvest waters. National water quality and depuration/relaying times are often classified using Escherichia coli, a poor proxy for norovirus levels in shellfish. The current norovirus assay is limited to only the digestive tracts of oysters, meaning the total norovirus load of an oyster may differ from reported results. These limitations motivated this work, building upon previo...

Global Trends in Highly Cited Studies in COVID-19 Research
CONCLUSIONS AND RELEVANCE: This study found that the total number of highly cited studies related to COVID-19 peaked at the end of 2021 and showed a downward trend until the end of 2022, while the origin of these studies shifted from China to the US and UK.PMID:37682572 | DOI:10.1001/jamanetworkopen.2023.32802

Broad-Spectrum Antiviral Effect of Cannabidiol Against Enveloped and Nonenveloped Viruses
Conclusions: It was demonstrated that CBD inhibits structurally dissimilar viruses, suggesting that this phytochemical has broad-spectrum antiviral effect, representing a valuable alternative in emergency situations during viral outbreaks, like the one caused by severe acute respiratory syndrome coronavirus 2 in 2020.PMID:37682578 | DOI:10.1089/can.2023.0103

< em > Serratia marcescens < /em > Outbreak at a Correctional Facility: Environmental Sampling, Laboratory Analyses and Genomic Characterization to Assess Sources and Persistence
We describe an environmental sampling and comparative genomics approach used to investigate a multi-year outbreak of S. marcescens at a correctional facility. Whole genome sequencing analysis revealed a predominant cluster of clonally related S. marcescens from nine patient cases and items associated with illicit drug use. Closely related strains found among items associated with case-patient cells and diluted Cell Block 64 (CB64), a quaternary ammonium disinfectant, and Break Out (BO), a multipurpose cleaner, highlighted their role as environmental reservoirs for S. marcescens in this outbreak. Comparative genomic analysi...
