There seems to be a lot of confusion in the droplet versus aerosol discussion and how these relate to the spread of COVID-19. Is it airborne and inhaled or droplet based via fomites and hands? The uncomfortable truth is that we have evidence for both modes. In this video we first define what a droplet and an aerosol is based on their behaviour in the environment. We then examine both through the findings from two published studies. We will also discuss how long viral particles survive and stay viable and able to infect after they fall on a surface or get suspended in the air. For COVID-19, we agree that the various transmission routes may predominate in different settings. The airborne route is relevant for hospitals and hospital staff as well as crowded and badly ventilated public spaces. Everyone else is more likely to get the virus through touching surfaces, bad hand hygiene and then touching their face. #medmastery #coronavirus #COVID19 #sarscov2 #coronaviruschina #coronavirustruth #coronavirusdeaths #WHO #wuhan #infection #pandemic #publichealth ----------------------------------------------------------- Links for reference: https://www.biorxiv.org/content/10.1101/2020.03.08.982637v1 https://jamanetwork.com/journals/jama/fullarticle/2762692 https://www.nejm.org/doi/full/10.1056/NEJMc2004973 https://bmcinfectdis.biomedcentral.com/articles/10.1186/s12879-019-3707-y ----------------------------------------------------------- More updates by Dr. Wiesbauer: COVID-19 Update 1: How to tell if a pandemic is likely to occur or not–R0 and the serial interval: https://youtu.be/wZabMDS0CeA COVID-19 Update 2: How to stop an epidemic - Herd immunity: https://youtu.be/IgV3L464Yh8 COVID-19 Update 3: Symptoms of COVID-19: https://youtu.be/1PLdl6NDGDE COVID-19 Update 4: Clinical characteristics of COVID-19: https://youtu.be/KQRt3DHkDp8 COVID-19 Update 5: Estimating case fatality rates for COVID-19: https://youtu.be/3xF2Ihjwbpw COVID-19 Update 6: Seasonality: will COVID-19 go away in the summer?: https://youtu.be/4baaKcZAAfQ COVID-19 Update 7: This is probably the most important picture of the whole Coronavirus-epidemic: https://youtu.be/6O96wkIxDls COVID-19 Update 8: Zinc and chloroquine for the treatment of COVID-19?: https://youtu.be/BIymfznD7YA COVID-19 Update 9: Hydroxychloroquine and azithromycin for the treatment of COVID-19–Review of study by Didier Raoult: https://youtu.be/C8dasnwweuw ----------------------------------------------------------- Useful resources: For checking daily developments of cases, deaths and more: https://gisanddata.maps.arcgis.com/apps/opsdashboard/index.html#/bda7594740fd40299423467b48e9ecf6 https://www.worldometers.info/coronavirus/ Other useful resources: Journal Watch: https://www.jwatch.org/na51020/2020/03/04/covid-19-collection-nejm-journal-watch-coverage New England Journal of Medicine: https://www.nejm.org/coronavirus Github collaboration: https://github.com/midas-network/COVID-19/blob/master/parameter_estimates/2019_novel_coronavirus/README.md#doubling-time CDC: https://www.cdc.gov/coronavirus/2019-ncov/php/preparing-communities.html WHO: https://www.who.int/emergencies/diseases/novel-coronavirus-2019 Nucleuswealth: https://nucleuswealth.com/articles/updated-coronavirus-statistics-cases-deaths-mortality-rate/ ------- Speaker: Franz Wiesbauer, MD MPH Internist & Founder at Medmastery LinkedIn: https://at.linkedin.com/in/franzwiesbauer PubMed: https://www.ncbi.nlm.nih.gov/pubmed/?term=Franz+Wiesbauer Check out our course library and register for a free trial account: https://www.medmastery.com/user/register Facebook: https://www.facebook.com/medmastery Twitter: https://twitter.com/medmastery Please Note: Medmastery's videos, medical lectures, medical illustrations, and medical animations are for medical education and exam preparation purposes, and not intended to replace recommendations by your doctor or health care provider.
