what is a common cold the common cold is
brought on by a viral infection
over 200 types of viruses can cause a
problem some symptoms include runny nose
sneezing headache raise temperature sore
throat cough and even red and dyes there
is no cure for it and antibiotics have
no effect against the viruses Cole
remedies do nothing to fight the virus
but sometimes they can provide a little
relief the common cold is spread in air
as Tiny mucus droplets coughed or
sneezed by those infected also from
person to person through contact such as
shaking hands or sharing objects like
cups or silverware many viruses can
survive up to 18 hours in the
environment and be picked up by people's
hands and carried to their eyes nose or
mouth now let's take a look at what
happens once we catch the cold or virus
to be more exact
typically virus particles from the air
will land on cells in the nose or throat
area then quickly multiply and kill the
host cell they continue to do this going
from cell to cell our immune system gets
alerted of these invaders and sends them
defender cells known as white blood
cells there are several different types
of white blood cells with two of the
most powerful being B cells and T cells
so what happens is the white blood cells
arrive at the scene of the crime and B
cells release antibodies which
immobilize the virus particles the T
cells may play a couple of different
roles they can help the B cells make
more antibodies giving more troops to
fight the virus or they can release
chemicals that go into an infected cell
and kill the cell and any virus inside
it then other white blood cells called
phagocytes come in and clean up
engulfing the virus particles and damage
cells the cold then subsides once the
virus is wiped out there are some
specialists B and T cells that retain a
memory of the virus so if this same
virus returns the immune system knows
exactly how to attack it this gives our
body what we call acquired immunity so
what can we do to minimize the risk of
getting the common cold well wash your
hands often especially after or when
you're in a public place
touching surfaces used by other people
avoid touching your face in public areas
keep household items clean such as
doorknobs and remotes use paper towels
as germs can live on cloth towels for
several hours maintain a healthy
lifestyle by staying active eating
nutritious foods and getting enough
sleep as this will keep your respiratory
and immune systems working in good
condition keeping stress to a minimum
will also help your immune system and
obviously avoid as best you can anyone
