Ferrate Compositions For Surface Disinfection

Methods for disinfecting a surface are provided which include contacting a surface with a solution comprising Fe(VI)O.sub.4.sup.2−, thereby disinfecting the surfaces. In some cases, the surface to be contacted with the solution is in a space suitable for human occupancy and the surface is arranged in the ambient of the space. In addition, solutions comprising Fe(VI)O.sub.4.sup.2− are provided. The solutions may additionally include a hypohalite salt and a surfactant.U

Environmental chemistry is most relevant to study coronavirus pandemics

version finaleInternational audienceOn May 18, 2020, the COVID-19 pandemic has globally killed 315,248 people since the virus outbreak in Wuhan, China, in early December 2019. As a matter of urgency, research has promptly focused on designing cures and vaccines, which is understandable, but is the classical ‘painkiller’ approach that will be less and less efficient in our globalized society because such an approach is treating the effect and not the original cause (Lichtfouse 2009, 2010). In particular, this is somehow underestimating environmental factors such as climate change and pollution that have more or less directly favored the pandemic. For instance, climate modeling has predicted increased risks of food- and waterborne diseases with very high confidence (Woodward et al. 2014). Similarly, air pollution has been shown to alter the immune system (Glencross et al. 2020; Bauer et al. 2012). Environmental chemistry, as the science of contaminants in the environment, thus deserves more attention to prevent future pandemics (Qu et al. 2020)

Classical and alternative disinfection strategies to control the COVID-19 virus in healthcare facilities: a review

International audienceThe coronavirus disease COVID-19 has spread throughout the world and has been declared as a pandemic by the World Health Organization on March 11th, 2020. The COVID-19 is caused by the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2). One possible mode of virus transmission is through surfaces in the healthcare settings. This paper reviews currently used disinfection strategies to control SARS-CoV-2 at the healthcare facilities. Chemical disinfectants include hypochlorite, peroxymonosulfate, alcohols, quaternary ammonium compounds, and hydrogen peroxide. Advanced strategies include no-touch techniques such as engineered antimicrobial surfaces and automated room disinfection systems using hydrogen peroxide vapor or ultraviolet light

The viral phoenix: enhanced infectivity and immunity evasion of SARS-CoV-2 variants

National audienceSARS-CoV-2 pandemic continues with emergence of new variants of concerns. These variants are fueling the third and fourth waves of pandemic across many nations. Here we describe the new emerging variants of SARS-CoV-2 and why they have enhanced infectivity and possess the ability to evade immunity
