Introduction

 

The measles come from paramyxoviridae
a family of viruses. The measles date back to the 6th century when
aisan physicians and north affican pysiicaians identified them as a similar
vurus to the smallpox. It’s wasn’t until 1912 that measles
were majorly introduced to the public because of a measles out break. After
this even over 6,000 deaths were pronounced yearly because of this virus
Measles is one of the most contagious of all human viruses, with about forty
million infections worldwide each year, and one to two million deaths.  Measles outbreaks are common in
underdeveloped countries. Since the measles are a virus it’s already a non
living organism which means you can’t kill it nor get rid of it. Before
reaching the most common rash stage of the measles you experience symptoms. The
symptoms include runny nose,fever,coughing, Koplik dots(red dots with blue
centers that form inside your mouth), and red eyes. After noticing these
symptoms red bumps will start forming all over your skin; first on your
forehead which will spread to your neck and then the rest of your body. The
measles are no longer as common as they used to be because there are now
available vaccines to prevent the virus from forming inside of you.

Viral Morphology

 

The measles virus is a virus made up of RNA and is a single
stranded virus that falls under the category of a virus family named
paramyxovirdae. The capsid shape for the measles virus is a sphere. The main
protein for the virus are L and P; P is a phosphor protein . The spike all have
different shapes at the top and are made up of two colors. The shapes on top of
the spikes are triangle, circles, and the colors that make up the spikes ae
purple and blue. The measles virus has 42 spikes surrounding it for protection
the total of spikes equal between the 42 so each spike is 21 is total.

Viral Transmission

The measles virus is virus that causes a rash to form all over
your body most people in the past centuries compared the virus to the small pox
virus. The virus first starts with common symptoms such as a fever/cold,
coughing, sinus, irritation in the eye, and koplick dots. When it reaches the
main stage, which is the rash you will start to notice it on your forehead
first. The rash (red inflamed blotches) later will affect your entire body all
the way down to your feet. The virus can be transmitted to the host by a simple
cough, mucus, and respiratory fluids. The virus has a limit when it comes the
host range. The measles virus does not infect animals or insects but only
humans.  The virus is so contagious that
90% people that have not gotten the vaccine in the past is most likely to catch
it just by surrounding an infected person.

Mode of Replication

The measles virus infects the body by respiratory tract. The virus
replicates itself by killing the host cell; the virus kills the host cell and
replicates by fusing toghether the cell membrane of neighboring cell. It
spreads through the body by entering the local lymphaticas which it then
spreads to the other lymphatics around the body.

Human disease

The measles virus is a very tough virus with many symptoms coming
your way. Some of the symptoms may include nausea,coughing,mucus,high fever,
skin rash,diarrhea,sore throats,headaches,swollen lymph nodes and Koplik dots
forming inside of your mouth.

Treatments

The measles virus doesn’t have a cure like any other virus because
there is no way to kill it since it’s already dead. The measles virus does
however have a vaccine to prevent it from spreading; the vaccine is named “MMR
vaccine”. The vaccine was introduced to the public in 1963 but it wasn’t as effective
so in 1968 a new and improved vaccine was introduced. There isn’t an actual
treatment for the virus but there are treatments to help mange symptoms the
treatments include, giving the infected person plenary of water and rest and to
prevent or manage fevers give the person a non- aspirin medication (ibuprofen
or acetaminophen).
