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

Circulation of Respiratory Viruses in the City: Towards an Agent-Based Ecosystem model
Bull Math Biol. 2023 Sep 10;85(10):100. doi: 10.1007/s11538-023-01203-x.ABSTRACTMathematical models play an important role in management of outbreaks of acute respiratory infections (ARI). While such models are generally used to study the spread of a solitary virus, in reality multiple viruses co-circulate in the population. These viruses have been studied in detail, including the course of infection and immune defense mechanisms. We developed an agent-based model, called ABM-ARI, assimilating heterogeneous data and theoretical knowledge into a biologically motivated system, that allows to reproduce the seasonal patterns o...

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...

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
