Bueno, después de que muchos medios hicieran una interpretación bastante loleante de un estudio del New England Journal of Medicine, convirtiendo la conclusión del estudio en "el virus aguanta 3 horas en el aire y 24 horas en el cartón", la OMS ha salido a desmentirlo y a interpretar las cosas con un poquito de cabeza.
Las noticias loleantes:
- Un estudio revela que en el aire el patógeno puede aguantar hasta tres horas
- "El virus permanece DÍAS EN LOS GRIFOS" (Esta es mi favorita sin duda)
- El coronavirus permanece hasta 3 horas en el aíre, pero hasta 5 días sobre el papel

Lo interesante:
To date, some scientific publications provide initial evidence on whether the COVID-19 virus can be detected in the air and thus,
some news outlets have suggested that there has been airborne transmission. These initial findings need to be interpreted carefully.
A recent publication in the New England Journal of Medicine has evaluated virus persistence of the COVID-19 virus.10 In this
experimental study, aerosols were generated using a three-jet Collison nebulizer and fed into a Goldberg drum under controlled
laboratory conditions. This is a high-powered machine that does not reflect normal human cough conditions. Further, the finding of
COVID-19 virus in aerosol particles up to 3 hours does not reflect a clinical setting in which aerosol-generating procedures are
performed—that is, this was an experimentally induced aerosol-generating procedure.There are reports from settings where symptomatic COVID-19 patients have been admitted and in which no COVID-19 RNA was
detected in air samples.11-12 WHO is aware of other studies which have evaluated the presence of COVID-19 RNA in air samples,
but which are not yet published in peer-reviewed journals. It is important to note that the detection of RNA in environmental samples
based on PCR-based assays is not indicative of viable virus that could be transmissible. Further studies are needed to determine
whether it is possible to detect COVID-19 virus in air samples from patient rooms where no procedures or support treatments that
generate aerosols are ongoing. As evidence emerges, it is important to know whether viable virus is found and what role it may play
in transmission.
Resumiendo, que la OMS recomienda precauciones contra las gotículas en el día a día y para transmisión aérea solo a personas que trabajen en ambientes en los que se puede nebulizar de forma constante el virus en el aire. Por ejemplo, gente que trabaja en las UCIS, porque los respiradores podrían estar soltando partículas del virus en el aire constantemente.
Vamos, que por respirar al lado de alguien con el virus no lo vas a pillar, y si alguien estornuda, el virus no se queda flotando en el aire 3 horas.
