Time until COVID-19 loses infectivity
Hello!
Regarding the new coronavirus,
when you look at the streets and commercial facilities,
everyone seems to be much more careful
about disinfecting hands and disinfecting handrails.
This time, I would like to summarize
the “time and methods until the infection is lost”
that is known up to this point.
First, attach the table below.
It is the time to lose the infectivity
when it adheres to the surface of each material.
* + : Infectious
* - : No infectivity
* Horizontal row : 0min, 30mins, 3hours, 6hours, 1day, 2days, 4days, 7days
* Vertical row :
copy paper
tissue paper
wood
cloth
glass
bill
stainless
plastic
surgical mask (inside)
surgical mask (outside)
* + : Infectious
* - : No infectivity
* Horizontal row : 5mins, 15mins, 30mins
* Vertical row :
Dilute household bleach 50 times
Dilute handsoap 100 times
Disinfection ethanol (70%)
Povidone iodine (7.5%)
Chloroxylenol (0.05%)
Chlorhexidine (0.05%)
Benzalkonium chloride (0.1%)
We must pay particular attention to the mask ...
Also if it still have infectious for 7 days,
you should disinfect immediately after use.
I also learned that the new coronavirus (COVID-19) is vulnerable to sunlight, as recently reported on the 23rd!
Sunlight seems to have the effects that it has the ability to inactivate viruses
that are present both on the surface of substances and in the air.
William Bryan, a science and technology advisor to the US Department
of Homeland Security,
told reporters at the White House.
It is thought to have the effect of inactivating.

↑ Sunlight is effective to new coronaviruses (COVID-19) for
① the surface of the substance, ② in the air,!!
After all, is the sun's light the strongest for evil power ?! ←
Joking aside,
To summarize the quoted articles
①The half-life of the new coronavirus amount is 18 hours
on a non-porous surface with a temperature of 21-24 degrees
and a humidity of 20%.
②When the humidity rises to 80%, the half-life decreases to 6 hours,
→When sunlight is added to this, it decreases to only 2 minutes
③When the new coronavirus (COVID-19) becomes an aerosol
that floats in the air, the half-life is 1 hour
at a temperature of 21-24 degrees and a humidity of 20%.
→When sunlight is added to this, it decreases to one and a half minutes
That is the above.
After all sunlight is the strongest ...!
By the way, [disinfection is also quite effective],
①Bleach (including alcohol 62-71% and hydrogen peroxide 0.5%)
②Household bleach (contains 0.1% sodium hypochlorite)
If you disinfect the surface with those, the coronavirus will be inactivated within 1 minute.
Thoroughly disinfect and apply to the sun!
