I know the HIV symptoms start showing up from 3 weeks to 6 weeks but when do they start to dissapear (average time). and how long does it take for half a drop of blood to dry and destroy HIV particles?

Signs and symptoms
The symptoms of HIV and AIDS vary, depending on the phase of infection. When first infected with HIV, you may have no symptoms at all, although it's more common to develop a brief flu-like illness two to six weeks after becoming infected. But because the signs and symptoms of an initial infection 鈥?which may include fever, headache, sore throat, swollen lymph glands and rash 鈥?are similar to those of other diseases, you might not realize you've been infected with HIV.

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) 鈥?the white blood cells that coordinate your entire immune system.

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 鈥?often one of the first signs of HIV infection
Diarrhea
Weight loss
Fever
Cough and shortness of breath
During the last phase of HIV 鈥?which occurs approximately 10 or more years after the initial infection 鈥?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 鈥?an infection that occurs when your immune system is impaired 鈥?such as Pneumocystis carinii pneumonia (PCP)
A CD4 lymphocyte count of 200 or less 鈥?a normal count ranges from 600 to 1,000
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 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 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.

Symptoms of HIV in children
Children who are HIV-positive often fail to gain weight or grow normally. As the disease progresses, they may have difficulty walking or delayed mental development. In addition to being susceptible to the same opportunistic infections that adults are, children may have severe forms of common childhood illnesses such as ear infections (otitis media), pneumonia and tonsillitis.
