What is the virus?

Viruses are small non-living disease-causing agents.

They are incapable of reproducing on their own.

They are unique as they can be alive and multiply only inside the cells of the other living beings.

After infecting a susceptible cell, they can multiply to produce more viruses.

Most of the viruses have RNA or DNA present in their genetic material. 

What is a Viral Infection?

A disease which is caused by the virus is called Viral Infection. Viruses can affect many organs in the body, including the reproductive, respiratory, and gastrointestinal systems. They can infect the liver, brain, and skin cells.

Viruses do spread easily and can be transmitted in various ways. We can get the viral infection through swallowing, inhaling, by insect bites, through transfusion of contaminated blood or through sexual contact.

What are the common symptoms of Viral Infection?

All the people who show these signs or symptoms need not take medical treatment.

Most of the viruses are self-limiting, and their symptoms get disappears on its own.

Activation of the body’s defense mechanism destroys the virus and this make the symptoms to fade away.

When do we say a viral infection is serious?

We all get exposed to a virus some or other time in our lives, not necessarily with any serious discomfort.

Sometimes it can get troublesome with very high fever, breathlessness and red rashes or spots on the body.

What happens if the virus enters into the body? – Replication

After entering the body, the virus transfers its genetic material into the cell and starts reproducing. They get multiplied in the cells and kill them by bursting. And they release new viruses to infect other cells. This cell damage leads to tissue destruction. Tissue destruction is associated with an immune response that causes viral disease symptoms.

In response to viral infection, the immune system gets activated. The immune system tries to get rid of the viruses with the help of white blood cells, antibodies, and other mechanisms. In this process, a person suffers from some symptoms like fever, malaise, headache, rash etc…

Body’s defense against Viral Infection

The entry of the virus into the human body triggers the body’s immune system. This defence mechanism starts with the activation of white blood cells (WBC), like monocytes, lymphocytes and T cells which destroy the virus or the infected cell.

If we get the same viral infection again, white blood cells remember this invader virus and respond more quickly.

Most viral infections initiate a protective response from the body’s immune system, except for some viruses like HIV.

Factors on which body’s response depend – susceptibility and immunity

How to maintain our immunity to the normal level?

As the same virus acts differently on a different individual, we need to protect ourselves by maintaining a normal immunity.

Our immunity gets influenced by our level of health. And our level of health depends upon our mind and body health. That means we need to maintain a healthy state of our mind and body.

We can maintain a healthy mind by trying to live in the present, which will help to keep our mind stress free. Always try to be away from negative emotions.

To maintain a healthy body, we need to have

What we should do if we get the viral infection

 There are a few basic things we should keep in mind, with a viral infection.

Viral infections can resolve without any treatment. If it is troubling you, you can take medical help.
