An Introduction
A virus is a microscopic organism and can be found in soil, water and even in other living organisms like humans, plants, animals, etc. Though a human body hosts viruses, not all become a cause of disease.
The immune system is responsible for protecting human beings against diseases caused by viruses by producing antigens. Notably, these antibodies do not just identify infection but also destroy them effectively.
Keeping that in mind, let us proceed to find out more about viral diseases!
What are Viral Diseases?
In simple words, these are infections or diseases caused by viruses. Now, the type of viral disease depends entirely on the virus that is causing it.
Often an infection caused by a virus can be fatal, while at other times the impact may not even be noticeable. Also, the same virus can affect different organisms in different ways.
These are Some of the Most Common Examples of Viral Diseases
Common cold
Influenza
Measles
Herpes
Rabies
Ebola
Severe Acute Respiratory Syndrome
Chickenpox
Mumps
Viral Hepatitis
AIDS
Polio
Viruses like human papillomavirus (HPV) can even become a cause of cancer in their host.

Causes of Viral Diseases
It is noteworthy that viruses cannot replicate on their own and are entirely dependent on a host. As a result, they are classified as parasites.
They transmit when an infected person comes in close contact with a healthy person. Notably, the composition of a virus influences its ability to spread.
Some of the conventional means of transmission include touch, contact with body fluids, ingesting contaminated water and diet, sexual contact, etc.
Symptoms of Viral Diseases
These are among the most common symptoms of viral diseases –
Fever and fatigue
Sore throat
Headache
Rashes
Swollen tonsils
Running nose
Body ache
Diarrhea and/or vomiting
It is noteworthy that symptoms for a particular viral disease may differ from those one another.
Treatment of Viral Diseases
There is no cure for most viruses. However, vaccination proves immensely useful when it comes to containing them.
Besides vaccination, the following is the advice that goes a long way in fighting against diseases caused by viruses.
Nutritious diet
Drinking adequate fluids
Proper rest
Prescribed medication for fatigue, fever, and body aches.
It must be noted that the treatment of a viral disease may vary widely, so it is best to avail medical treatment and avoid self-diagnosis.
Immunity
An organism can resist or combat the venereal infection and prevent it from turning into a full-fledged disease. In a broader sense, immunity is classified into two types – innate immunity and acquired immunity.
Innate immunity is present in organisms since birth and is usually inherited from their parents. Innate immunity is manifested as barriers, which include – physical, cellular, and physiological, and cytokine.
On the other hand, acquired immunity develops over time throughout an organism’s lifetime. It is further manifested as active immunity or passive immunity.
The human immune system comprises lymphoid organs, antibodies, lymphoid tissues, and immune cells. Human beings with strong immunity are less likely to succumb to diseases caused by viruses.
