This is an age of science and technology. Human life is certainly longer today than what is used to a few decades ago.  A number of terrible diseases continue to stare the scientists in the face and the men of science stand just bewildered and confused.  A rather recent discovery in this list of incurable diseases is AIDS (Acquired Immuno- Deficiency  Syndrome) which has created a terrible scare in the world.  It has already taken a toll of several thousand lives in America and Europe.  It has been reported that the disease has, in mild forms, entered India also. The Government of India has launched a big offensive against the terrible disease.  Although there is no reason  for immediate alarm yet the public is being educated about the symptoms, causes, remedies, precautions etc. concerned with this fell disease.

The entire media, radio, television, newspapers, and periodicals all over the world are sounding a note of warning and asking the people to take all precautions to save themselves from this killer diseases.  AIDS education programme should, in fact form a part of the high school curriculum.

 AIDS is an illness in which the body’s natural system starts failing by slow degrees.  Human body has an army with various weapons of its own to protect itself from invaders like germs.  A patient suffering from AIDS loses these weapons.  He cannot fight diseases and becomes defenceless.  He quickly falls an easy prey to several diseases and becomes helpless.  AIDS is caused by a virus which infects the white cells of the body. It is a disease which is difficult to diagnose.  The diagnosis is based on a series of complex blood tests.  Early symptoms of this disease are a significant loss of weight, swollen glands, fever and night sweats, extreme lethargy and oral or esophageal infection.
