Why your new purchase won’t make you sick
... U.S. health officials said on Monday that there is no evidence to
support the transmission of the new coronavirus through imported goods.
Memorize this Lesson for life: ask "Where's the
Evidence?"
“In general, because of poor survivability of these coronaviruses on
surfaces, there is likely very very low risk of spread from products or
packaging that are shipped over a period of days or weeks at ambient
temperatures,” Dr. Nancy Messonnier, director of the Center for Disease
Control’s Center for Immunization and Respiratory Diseases, said in a Monday
morning press briefing.
Even in the worse case scenario — say, a sneezing-person packaged your
$700 used Apple iPhone 11, bought on Amazon and shipped to your home by air
via United Parcel Service or FedEx — isn’t dangerous.
How 2019-nCoV Spreads
https://www.cdc.gov/coronavirus/2019-ncov/about/transmission.html
Most often, spread from person-to-person happens among close contacts (about
6 feet). Person-to-person spread is thought to occur mainly via respiratory
droplets produced when an infected person coughs or sneezes, similar to how
influenza and other respiratory pathogens spread. These droplets can land in
the mouths or noses of people who are nearby or possibly be inhaled into the
lungs. It’s currently unclear if a person can get 2019-nCoV by touching a
surface or object that has the virus on it and then touching their own
mouth, nose, or possibly their eyes.

AIR
in hospitals is a source of microorganisms. Air disinfection
reduces wound infection rates as measured in hospital settings. Effective
air disinfection equipment requires professional engineering and room air
flow pattern studies plus close monitoring. Filtering units placed other
than at the source of new air mixes the disinfected air with untreated air
and significantly diminishes effectiveness. Treatment must occur where the
air actually enters the room. Air change rates listed as so many times per
hour for modular filtration units is not an indication of any amount of room
disinfection. Filtration is not as effective as Ultra Violet treatment. UV
however requires equipment that can be dangerous and ineffective if not
professionally installed and diligently maintained by a knowledgeable staff.
There is no reason to suspect a dangerous concentration of pathogenic
air-borne microorganisms in non-medical settings.
Air-borne sources are problematic. Fungus and mold are the only
microorganisms that can be detected to a degree, and everything depends on
where the test is done, how it is done because it leads to no wider
conclusions about air generally. Even spores settle out of the air at a rate
of 3 feet per hour. There are no reasons to suspect normal air as being a
source of infection.
SNEEZING and COUGHING
are dangers for airborne spread of infectious microorganisms in a normal
environment that we would like to keep as free of microorganisms as
possible. The aerodynamics, just like a spray gun, produces great numbers of
droplet nuclei which will be suspended in air and for long periods of time.
It is these suspended particles that carry infectious microorganisms that
spreads disease. A sneeze or cough into a tissue prevents aerosol projection
and transmission of airborne infectious microorganisms.. Once on the tissue
surface the tissue can be safely discarded and the spread of possible air
borne contamination eliminated. Sneezing and coughing must always be done
into a tissue or the crook of the arm. Have an easily accessible supply of tissues for customers and
visitors.
