Background: To slow the increasing global spread of the SARS-CoV-2 virus, appropriate disinfection techniques are required. Ultraviolet radianon (UV) has a well-known antiviral effect. But measurements on the radiation dose necessary to inactivate SARS-CoV-2 have not been pub- lished so far. Methods: Coronavirus inactivation experiments with ultraviolet light performed in the past were evaluated to determine the UV radiation dose required for a 90% virus reduction. This analysis is based on the fact that all coronaviruses have a similar structure and similar RNA strand length. Results: The available data reveals large variations, which are apparently not caused by the coronaviruses but by the experimental conditions selected. If these are excluded as far as possible, it appears that coronaviruses are very UV sensitive. The upper limit determined for the log-reduction dose (90% reduction) is approximately 10.6 mJ/cm2 (median), while the true value is probably only 3.7 mJ/cm2 (median). Conclusion: Since coronaviruses do not differ structurally to any great exent, the SARS-CoV-2 virus – as well as possible future mutations – will very likely be highly UV sensitive, so that common UV disinfection procedures will inactivate the new SARS-CoV-2 virus without any further modification.
Introduction: The coronavirus disease 2019 (COVID-19) is a respiratory tract illness resulting from Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection, which has spread all over the globe, making it a major public health challenge across health systems. Simultaneously, numerous rumors, misinformation, and hoaxes appeared on several social media platforms regarding the etiology, outcomes, prevention, and cure of the disease1. The pressing issue is fake news spread more rapidly in social media than the ones from reliable sources and damages the authenticity balance of news ecosystem. Methodology: These articles contained diverse study methods (survey, content analysis, interview, literature review & others) and paradigm models (quantitative, qualitative) to identify the widespread misinformation and its impacts. Conclusion: Mainstream media platforms mostly contain fake news and rumors. The long-standing issue of misinformation regarding different socio-political issues is under constant discussion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
