Airborne Virus Aspects 2020

A great controverse topic is involved in covid-19 transmission model and if it is possible or not an AIRBORNE way.This work is a collection of article involved in some respiratory virus pattern of diffusion to try to clear this relevant question.A final list of relevant references is reported. Coronavirus was finded to have characteristic pattern of chemical -physical properties at X-ray cristallograpy.This fact influence some diffusion properties related also Brownian moto and shielding effect .Not only carrier size is relevant for airborne transmission of some respiratory virus but also virus size and electrical feature, envelope composition and other .The virus envelope seem involved in avoiding strategies of virus to escape to the hosts immune system.In this work aspect related chemical -physical aspect of coronavirus are investigated.The logarithmic rapid explosion in France, Spain and UK of a second wave of covid-19 seem to reveal other then simply direct contact and by droplet diffusion: airborne can be an real hypotesys of work.
