Today, I would
like to introduce norovirus. I was infected with this virus last year. And then
I have an entrance examination for Universal of Tsukuba in some weeks. I was so
flustered. It makes me not eat anything and feel sick. It is part of my memory
in a sense.
Norovirus is a
virus that cause acute gastroenteritis. It makes an infected person not only
having loose bowls but also vomiting. It is a special feature of this virus. And
norovirus have very strong resistance to a disinfectant. It is strong to high temperature
and drying, and can survival in water for a long time. Very troublesome. There
are some different type of norovirus. So same person can be infected with some
different norovirus. An infected person cannot be off his guard after he get
well.
Norovirus
intrude into human body through a mouse in almost all case. Feces and vomited
matter of infected person have virus. In many cases it infect from these excreta.
Or through foods that infected person make, many virus infect.
Latent period of
norovirus is from 24 to 48 hours. Main symptoms are a sickly feeling, vomiting,
diarrhea and stomachache. Running a temperature is slight. Usually, infected
people get well in two days. No after-effected.
There is no
anti-virus drug to norovirus. Usually symptomatic treatment is used. The there
is a point that infected person do not forget. Infected person must not take a strong
medicine for diarrhea. If he take a strong medicine for diarrhea, virus keep
stay in digestive tract. It makes him not be well for a long time.
If you do not
want to be infected this virus. You have to not forget some point. You have to wash
hands with soup after you go to the lavatory or before you have a meal. You have
to avoid use a same towel with plural people. You have to heat foods keeping 81
degrees Celsius for more than a minute. The virus I foods can lose
infectiousness by heating. If you clean up feces and vomited matter of an infected
person, you must wear vinyl glove and must disinfect with a bleach.
When you are
infected with virus you should be careful not to pass a disease on someone who
are around you. If you feel sick or have loose bowels, you have not to do make
food and give it someone else.
