There is a very long-standing liaison between human beings and virus that wander unreservedly in our environment. Virus has a long history of disconcerting people.

A virus is a microorganism that is not visible to the naked eye. It is highly contagious and communicable. A virus attacks and clips to a living cell of the human body. It then discharges its DNA or RNA, which smashes the original genetic material and functioning of the cell. But before the victimized cell expires, it leaves or releases more of that virus. The virus multiplied in such a fashion impedes the growth and working of other healthy cells too, so much so that sooner or later the entire body comes in its grips. However, the immune system of the body endeavors its best to brawl the viral attack. But it does not succeed in all the cases. Due to this reason, the doctors and dieticians prescribe a healthy diet rich in nutrition that strengthens the resistance of the body.
