order to encourage research development in the field of Sciences. OMICS
Group invites articles from authors, scientists, research scholars and
professors who are professed in their disciplines and makes the scientific
literature available online at free of cost. We have an eminent editorial panel that
evaluates the manuscripts submitted by the scholarly community. This post provides information about an
overview on virus, causes of virus and types of viruses.
An overview on Virus
A Virus is a single-celled tiny organism
that triggers infection in the body. Virus is born out of the genetic
substances, such as DNA or RNA. Basically, it thrives on destroying other cells
in the body thereby forcing the cells to develop duplicates of them.
Viruses are capable of affecting any part of the human body and can trigger infections, such as flu, cold and gastroenteritis, chicken pox etc., Respiratory tract is the most common form of viral infection that affects an individual. Besides, it infects all forms of organism ranging from animals to plants and bacteria, archaea.
A virus is
incompetent to perform independent metabolic activity and replication. The intensification of virus impedes the
attacked cell’s internal mechanism. Usually, it terminates and discharges the
viruses in the bloodstream. Since Antibiotics are incapable to arrest viruses,
a special type of developed drug, known as vaccine will help in combating the
virus.
Out of
nearly 5000 known species of viruses, more than 200 have been recognized as
disease causing in humans.

Causes of Virus:
Viruses can spread in many ways, such as:
·
Coming
into contact with an infected individual.
·
Swallowing,
inhalation of contaminated food and liquid.
·
Practicing
in unsafe sex.
Apart from
the above, other factors such as eating habits and poor hygienic environment
contribute to the risk of contracting virus.
Types of Virus:
·
Common cold is a recurrently occurring viral
infection and it takes the shape of flu, cold and gastroenteritis etc.,
·
Influenza, also known as flu, is a
respiratory infection evolved out of virus. The affected individual develops
symptoms such as fever, body chills and headache etc. In contrast to other
viral respiratory infections. The viruses of flu and cold are prone to transmit
to people at public places.
·
The Gastrointestinal system virus leads to varied symptoms such as
diarrhea, fear and vomiting, abdominal pain. Stomach viruses tend to transmit
through infected food or water and can cause viral gastroenteritis. Also, hand
washing done in an improper way following a bowel movement, or handling a nappy
can result in spreading the disease from person to person.
·
Chicken pox or the
Common Whart is yet another kind of infectious ailment that occurs in children under
the age of 15. In some cases, older people also susceptible to it. It gets transmitted quickly through human
contact. The affected individual exhibits symptoms, such as headache, fiver and
itchy rash. It takes 5 to 11 days to get out of this infection. In most of the
cases, the virus will not return to haunt the individual.
