Reannouncement of state of emergency for new coronavirus infection
15th, January Reiwa 3rd
President : SHIMIZU Sumito
As the new coronavirus infection has spread, a second state of emergency was declared in
11 prefectures. Early vaccination and establishment of new therapeutic drugs have been
desired, but until then, I would like to mention again the basic measures each individual,
home, company should keep in the social life (Reference materials from the Ministry of
Health, Labor and Welfare)
１．Where does the new coronavirus invade and infect the human body? The virus istransmitted by invading the mucous membranes of humans' eyes, nose, mouth. First of all,we should understand it firmly. It does not invade from intact skin. If no infection control
measures are taken, the infection is transmitted from the mucous membranes of the "eyes,
nose, mouth," by the following route.

1) By talking with an infected person for a long time (about 15 minutes or more) at ashort distance (within about 1 m), the virus contained in the infected person's breathand cough splash invades through the "eyes, nose, mouth". A conversation just withina few minutes has low risk. In addition, simply passing by an infected person does notcause infection. Infect by. Conversations within minutes are low risk. In addition,
simply passing by an infected person doesn’t cause infection.
2) When the air dries and the humidity drops below 39%, the virus becomes lighter andis included in the sighs and coughs of infected people. Then the virus flies far and isinhaled by humans. Ventilation and humidification need to be improved.
3) The virus can survive on metal or plastic surfaces for up to 3 days. When we touch
doorknobs or handrails with the virus on it and unknowingly put the virus's hands on
our mucous membranes of "eyes, nose, mouth and excretion part", it cause infection.
(One survey tells that people unknowingly touch the mucous membranes of their "eyes,
nose, and mouth" about 10 times an hour)
Also, The possibility could be increased that they share towels and dished used byinfected people.
２．What are the symptoms when people get infected?
Similar to those of a common cold or flu, fever, malaise, sore throat, cough, muscle aches,
and loss of appetite would be caused. Some people complain of abnormal smell and taste.
It is said that as approximately 80% of people who are infected are asymptomatic, theinfected may have spread the infection to the people around them (This is the reason why
we need to wear a mask in the crowd). If the symptoms progress a little, you may feel
suffocating when you move (at this time, if you do not see the doctor immediately, the riskof becoming severe increases).

３．How should we prevent infection ?
The prevention of infection is preventing the invasion of the virus from the "eyes, nose,and mouth".
① To avoid "three dense situations". We should live by avoiding the three "closed
spaces" of "crowded places", and "close-contact settings".
② Never fail to wear a mask(cover your nose and chin firmly) when you enter a crowdof people(when there are other people in a short distance such as going shopping at asupermarket, getting on a train, getting on a bus, etc.,). Even if people talk at closerange, you can prevent infection by wearing masks with each other. It is more helpful
for preventing infection by wearing hay fever glasses in addition to a mask.
③ Don’t touch "eyes, nose, and mouth" carelessly. Before touching "eyes, nose, andmouth,", be sure to wash your hands thoroughly(It is more effective to use both
medicated soap with running water and rubbing alcohol).
④ Try to ventilate the room(Keep windows and doors open little by little, and open themwidely on a regular basis)⑤ Check your physical condition by taking body temperature every day. If you have afever or cold, avoid going out and treat yourself at home. If fever continues (about 2days for people with underlying illness, 4 days or more for people without underlyingillness), you should call nearby "Consultation Center, Returnee / Contact CounselingCenter," nearest community health center" and receive advice (for PCR test) before
going to a medical institution directly.
⑥ Try to make moderate exercise. Make sure to refrain from going out, but if you stayat home all the time, your physical strength and immunity will decline. Then try toexercise moderately, such as taking a walk around the house. You don’t need to wear
a mask if a number of people is not around you within 2 meters outdoors. Because
there is a low possibility that people get infected.
４．What should we do if a member of family gets infected ?
It is recommended that the following infection control measures should be taken.
(1) Divide the room as possible as we could.
(2) Wear a mask in the house as possible as we could.
(3) Gargle and wash your hands diligently.
(4) Ventilate as possible as you could.
(5) Disinfect doorknobs,
toilet seats, etc. that theinfected person touches.
(6) Avoid sharing towels
and dishes.
(7) Let infected people
take a bath last.

Countermeasure keywords advocated by the world's top researchers forcoronavirus infection countermeasures
1. Disinfection technology ← Uchiya has already introduced.
① Cleaning with water and soap → Things and fingers② Hot water → Things③ Alcohol disinfectant → Things(miscellaneous goods, quasi-drugs) and fingers(pharmaceuticals / quasi-drugs)④ Sodium hypochlorite disinfectant (chlorine bleach) → Things (miscellaneous goods,pharmaceuticals / quasi-drugs)⑤ Detergent (surfactant) → Things (miscellaneous goods, pharmaceuticals / quasidrugs) and fingers (unevaluated)⑥ Hypochlorite water (those that meet certain conditions) → Things (miscellaneousgoods)
2. Ultraviolet rays(ultraviolet sterilizer) Japanese technology has let put into practical use
in hospitals. When the wavelength 222 nanometer (this level does not cause skin cancer)
is irradiated for 10 seconds, coronavirus gets detoxified. Ultraviolet rays are effective
against coronavirus, for sterilization.
3. Inactivation of coronavirus (ozone generator and photocatalyst device) ← Uchiya has
already introduced. The oxidizing power of low-concentration ozone (0.000017%)
detoxifies coronavirus.
4. Evaporation ← Increase humidifiers
It is known that virus droplets fall to the ground quickly in high humidity conditions, but
could fly far away when it is dry. When the humidity is 39% or less, the water content of
the virus droplets evaporates and becomes lighter, so the falling speed becomes slower
and the virus floats in the air for about 30 minutes. At a humidity of 30%, it flies twice as
far as at a one of 60%. and the more dry it is, the wider the virus droplets spread.
5. Humidifier (humidifier) ← Increase humidifiers
When the air dries, the mucous membrane of the throat also dries and it causes a decreasein blood flow. As the result it causes a decrease in immunity and gives inflammation to
the throat prone. A humidity of 50% -60% removes 50% of atmospheric droplets and it
activates pili in the throat, which eliminates coronavirus. In this way, the room should behumidified to 40% or more.
