When out walking, it is quite common to be able to smell perfume
from a distance of 10m from the wearer.
This makes me think that Covid particles must be heavier than
perfume by a factor of 5 (if you accept the government's 2m rule
Or is there another factor that plays into the airbornness of
perfume and Covid particles.
"Then, in 1934, W.F. Wells at the Harvard School of Public Health
showed that large droplets (bigger than 0.1 millimetre) tended to
fall and settle on the ground within a distance of two metres,
while smaller droplets evaporated and the virus particles left
behind could remain suspended in the air for a long time."
"Since then, respiratory diseases have been divided into those
transmitted via droplets (usually from close contact) and those
that are airborne and can spread over longer distances, such as
measles or tuberculosis."
"Does it mean that COVID-19 is spreading from person to person
through aerosols? I would say definitively not," Loeb said.
"The reason we know that is because all around the world we
have hundreds of health-care workers who are taking care of
patients wearing regular masks," she said. "If this were
airborne - if this were usually in those small [aerosol]
particles — all those health-care workers would be getting sick."
If this were measles-like, we'd be using entirely different rules.
Part of what you're doing, is keeping your distance from super-spreaders.
When some barber shop employees got COVID, none of their customers
got it, because (amongst other things) mask policy.
The chick with the perfume might be a proxy for measles,
but not for COVID. She would be indicative of "how careful
you'd need to be to avoid measles".
