Throughout
our life we all become sick at one point or another. Sickness can range from
mild common cold to something as severe as cancer. Although what is under the
surface is much scarier than what appears. Viruses not only negatively affect
living organisms but are capable of affecting an entire society.
Viruses
are not living and are too small to be seen by the naked eye. Without a host
cell they subsist as a protein coat or capsid covered by a membrane (Netdoctor). However with a host cell, viruses
grow to be infectious and in some instances, cause serious damage. Since a
virus isn’t alive they can’t reproduce; in replace they take over a host cell using
its machinery to produce more of their own
(Netdoctor). In some cases the very own host is our body and when that
happens we typically grow sick depending on what virus is in us. Viruses mainly carry negative effects on
living organisms, they cause something as little as the cold to something as
dramatic as cancer.
Even
though viruses are not visible to the naked eye, they are visible in many other
places. Some viruses may start out as an itch but quickly worsen to a flow
blown rash, commonly known as shingles or chicken pox (PubMed Health). On the other hand, a virus can start from a blood
sucking insect, such as the mosquitoes. For example the West Nile Virus that
started in Africa. It is a disease
spread by mosquitoes; the damage could range from mild to severe (PubMed Health). While the West Nile Virus was spread from a
mosquito, influenza was a viral infection that attacks the respiratory system,
lungs, nose and throat. After World War 1, influenza broke out and the virus
killed over 20 million people (Mayoclinic staff).
Viruses
may be harmful but they can be prevented and there are treatments available to
those in need. Many mild viruses such as the cold, cough and flu can be treated
with regular over the counter medicine or a vaccination shot. Unfortunately there is no guarantee to stop
viruses from spreading but there are ways to avoid it, such as washing hands,
not sharing liquids and obtain frequent vaccinations.
Overall
viruses are not healthy for living organism, as well as society. They cause
many unfortunate issues and concerns. It is amazing how something so small can
do so much damage to not only one person but to an entire city or even country.
