Influenza, or "flu," is a caused by a virus infecting the respiratory system (nose, throat, bronchial tubes, lungs).
Mostly the mucous tissue in the respiratory system, but mucous tissue in the gastrointestinal system is also affected.
The hundreds of different viruses responsible for causing a common cold all make their attack on the human body in the upper respiratory tract. The virus particles attach to the cells of the mucous tissue in sinuses, nose, mouth, eyes, throat and trachea first. The bronchial tubes and lungs also can be affected. In addition to the respiratory system and eyes, the immune system is triggered to work to rid your body of the invader with an immune response, which will employ resources from the circulatory system and blood forming organs.
The measles virus is transmitted via respiratory secretion and causes very serious illness. It first infects the conjunctiva, respiratory tract urinary tract and the central nervous system.

They both cause infectious diseases of the respiratory system.
The system will become slow ,Then always programme's will be hanged in this we know the system is affected .............
Bird flu primarily targets the lower respiratory system due to the presence of specific receptors in the cells of the trachea and lungs that are more compatible with the virus. These receptors, known as avian-type sialic acid receptors, are more abundant in the lower respiratory tract, allowing the virus to efficiently enter and infect those cells. In contrast, the upper respiratory system has different receptor types that are less suited for avian influenza viruses, which may explain the virus's limited impact in that area.
Immune system
An upper respiratory infection is contagious for as long as the active virus is in your system. Taking an antibiotic will help rid the body of the live virus. You will remain contagious for 24 hours following the first treatment of the antibiotic.
The respiratory system is the first system targeted and hit in any influenza. Although stomach and GI viral infections are sometimes called "stomach flu", those are not really caused by an influenza virus, it is another kind of virus. As influenza worsens in some individuals other body systems can be severely affected secondarily, such as renal (kidneys), central nervous system (fever induced seizures), etc.
Yes. However the AIDS computer virus is nothing like the Human AIDS virus. Your computer can not get the Human AIDS virus. This computer virus was written in 1990, and affected .com files running on the DOS system.
