BASIC - SYMPTOMS
   
 Someone might be infected with HIV and still look very healthy and alright, this is because HIV does not just damage the immune system in a day or in weeks to develop into AIDS, it has stages through which it totally damage the immune system, and at the time it means that HIV had damaged it targeted cells ( the T4 lymphocyte) and reduced it amount to about 200 T4 lymphocytes per blood micro liter.

 SYMPTOMS
 
  After one to three weeks contacting HIV, the first set of symptoms are a short flu-like illness that last one to four weeks, such as fever, skin rash, headache, sore throat, tender lymph nodes and an indistinct mood of discomfort. During this level of infection, which is called the acute retroviral syndrome, HIV reproduces quickly in the blood circulating through all the human body and especially in the organs of the lymphatic system.
The immune system then prepares its defenses against HIV in order to reduce but it cannot completely remove it from the blood. Infected persons pass through an asymptomatic stage, which has no symptoms and last for several years, during this stage, HIV continues its reproduction, and the infected person remains in good health. That's how HIV increasingly destroy the immunity, and during this stage, HIV can be transmitted to other persons.

Then when the number of T4 lymphocytes decrease to 200 per blood micro liter, an assortment of not life-threatening symptoms appear and last a few months to several years. Including these symptoms; extensive weight loss, fatigue, fever, diarrhea, thrush (a fungal mouth infection), and vaginal yeast infection in women. These symptoms are grave enough so that the infested person seeks medial treatment, so they make an HIV test, which is done by the examination of blood samples of the person being tested.

The test is made by adding HIV proteins, which have been commercially prepared to the tested blood. If there are HIV antibodies in the blood sample, they will bind to the viral protein, and this union will mean that this blood is infected with HIV (HIV+). If the test proves negative, this person may still be infected with HIV because HIV antibodies are created months after the infection. And that's how most of HIV infected person first know about their infection.

If T4 lymphocyte level drop below 200 T4 lymphocytes per blood microliter, the late symptomatic stage develops and 26 opportunistic infections and rare cancers appear and this could be the sign of the complete development of AIDS, without medical treatment this phase my last months and years and its increasing effects of the illness usually result death.
HIV infection in children increases more quickly because of their incomplete immunity, that's why more than half of the infected children die before age of two
 
 
 
 Opportunistic infections
 
 When HIV succeeds in damaging an immune system, the following (opportunistic) infections may occur:
 
 
 
 Pneumonia
 
 Pneumonia is a lung infection, caused by the fungus Pneumocystis carinii that chunk the lungs of delivering adequate oxygen to the blood, which leads to severe shortness of breath accompanied by fever and dry cough. This fungus is being fought by the immunity of healthy persons when it infect most of them in childhood.
 
 
 
 Meningitis
 
 Meningitis is an inflammation of the membranes that covers the brain and it's caused by the Cryptococcus.
 
 
 
 Histoplasma capsulatum
 
 This disease is usually accompanied by weight loss, fever, and respiratory compilations.
 
 
 
 Tuberculosis
 
 Tuberclosis is a  lung infection caused by the bacterium Mycobaterium tuberulosis that becomes more grave in AIDS patients.
 
 
 
 Kaposi's sarcoma
 
 Kaposi's sarcoma is a cancer of blood vessels that is being caused by a herpes virus that create purple skin lesions, which an be transmitted to internal organs and cause death.
 
 Other opportunistic infections includes anemia, diarrhea, Cervical cancer and fever
