First Symptoms Of Hiv

I know the symptoms of HIV begin to arrive from three weeks to six weeks, but when they start to disappear (average). and how long does it take for half a drop of blood to dry and destroy HIV particles?

Signs and symptoms
Symptoms of HIV and AIDS vary, depending on the stage of infection. When first infected with HIV, you can have no symptoms, but it is more common to develop a brief flu-like illness two to six weeks after infection. But because the signs and symptoms of an initial infection - which can include fever, headache, sore throat, swollen lymph glands and rash - are similar to those of other diseases, you may not be realize that you have been infected with HIV.

Even if you do not have symptoms, you are still able to transmit the virus to others. Once the virus enters your body, your own immune system is also under attack. The virus multiplies in the lymph nodes and slowly begins to destroy your helper T cells (CD4 lymphocytes) - 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 the cells of the immune system, 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
Cons cough and shortness of breath
During the last phase of HIV - which occurs approximately 10 years or more after 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 indicated by a positive test for HIV antibodies and at least one of the following:

The development of an opportunistic infection - an infection that occurs when the immune system is weakened - such as Pneumocystis carinii pneumonia (PCP)
A CD4 count of 200 or less - a normal range of 600-1000
When AIDS develops, your immune system has been severely damaged, so you susceptible to opportunistic infections. Signs and symptoms of some of these infections may include:

Soaking night sweats
chills or fever higher than 100 F for several weeks
dry cough and shortness of breath
Chronic diarrhea
white spots or unusual lesions on your tongue persistent or in your mouth
Headaches
Blurred vision and distorted
Weight loss
You can also begin to experience signs and symptoms of infection by HIV itself later, such as:

Persistent, unexplained fatigue
Soaking night sweats
chills or fever higher than 100 F for several weeks
Swollen lymph nodes for more than three months
Chronic diarrhea
persistent headaches
If you are infected with HIV, you are also more likely to develop certain cancers, especially Kaposi's sarcoma, cervical cancer and lymphoma, although improved treatments have reduced the risk of these diseases.

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