The symptoms of HIV and AIDS vary, depending on the phase of infection.
Early infection
When first infected with HIV, you may have no signs or symptoms at all, although it's more common to develop a brief flu-like illness two to four weeks after becoming infected. Signs and symptoms may include :
· Fever
· Headache
· Sore throat
· Swollen lymph glands
· Rash
Even if you don't have symptoms, you're still able to transmit the virus to others. Once the virus enters your body, your own immune system also comes under attack. The virus multiplies in your lymph nodes and slowly begins to destroy your helper T cells (CD4 lymphocytes) the white blood cells that coordinate your entire immune system.
Later infection
You may remain symptom-free for eight or nine years or more. But as the virus continues to multiply and destroy immune cells, you may develop mild infections or chronic symptoms such as :
· Swollen lymph nodes often one of the first signs of HIV infection
· Diarrhea
· Weight loss
· Fever
· Cough and shortness of breath
Latest phase of infection
During the last phase of HIV which occurs approximately 10 or more years after the initial infection more serious symptoms may begin to appear, and the infection may then meet the official definition of AIDS. In 1993, the Centers for Disease Control and Prevention (CDC) redefined AIDS to mean the presence of HIV infection as shown by a positive HIV-antibody test plus at least one of the following :
- The development of an opportunistic infection an infection that occurs when your immune system is impaired such as Pneumocystis carinii pneumonia (PCP)
- A CD4 lymphocyte count of 200 or less a normal count ranges from 800 to 1,200
By the time AIDS develops, your immune system has been severely damaged, making you susceptible to opportunistic infections. The signs and symptoms of some of these infections may include :
· Soaking night sweats
· Shaking chills or fever higher than 100 F (38 C) for several weeks
· Dry cough and shortness of breath
· Chronic diarrhea
· Persistent white spots or unusual lesions on your tongue or in your mouth
· Headaches
· Blurred and distorted vision
· Weight loss
You may also begin to experience signs and symptoms of later stage HIV infection itself, such as :
· Persistent, unexplained fatigue
· Soaking night sweats
· Shaking chills or fever higher than 100 F (38 C) for several weeks
· Swelling of lymph nodes for more than three months
· Chronic diarrhea
· Persistent headaches
If you're infected with HIV, you're also more likely to develop certain cancers, especially Kaposi's sarcoma, cervical cancer and lymphoma, although improved treatments have reduced the risk of these illnesses.
