HIV infection comes in three stages. The first position is called sharp infection or seroconversion, and it typically happens within two to six weeks after baring or becoming infected. This is when the body's immune organization puts up a contend with against HIV. The symptoms of sharp infection look like to those of other viral illnesses and are often compared to those of the flu. The symptoms may last a week or two and then entirely go away as the virus goes into a non-symptomatic position.
The primary symptoms of narrow HIV infection may comprise:
Migraine
Diarrhea
Nausea and vomiting
Weariness
Aching muscles
Painful throat
Red foolhardy that doesn't tickle, usually on the torso.
Feve
After the first seroconversion interval, the immune system loses the fight with HIV and symptoms go away. HIV infection goes into its second position, which can be a extensive duration without symptoms, called the asymptomatic time. This is when people may not know they are infected and can pass HIV on to others. This interval can last 10 or more years.
During this interval without symptoms, HIV is slowly murder the CD4 T-cells and destroying the immune system. Blood tests during this period can expose the numeral of these CD4 T-cells. Normally, a individual has a CD4 T-cell regard between 450 and 1,400 cells per microliter. This horde changes constantly, depending on a person's conditions of health. For an HIV-infected human being, the numeral of CD4 T-cells steadily drops, making them defenceless to other infections - and in risk of developing AIDS.
