The Symptoms of HIV/AIDS - the First Stage
By Dr.Fourkan Ali
HIV infection comes
in three stages. The first stage is called acute infection or seroconversion,
and it typically happens within two to six weeks after exposure or becoming
infected. This is when the body's immune system puts up a fight against HIV. The symptoms of
acute infection look similar 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 completely go
away as the virus goes into a non-symptomatic stage.
The initial symptoms
of acute HIV infection may include:
You think you have
come in contact with HIV. Doctors can now prevent HIV from taking hold in the
body if they act quickly after initial infection. Health care workers, police,
and firefighters who are exposed to HIV-infected blood often use a
process that involves taking anti-HIV drugs to protect themselves. These drugs
must be taken within 72 hours of initial exposure.
You may be tested for
HIV using highly sensitive tests that detect both HIV antigen, a protein
produced by the virus immediately after infection, and HIV antibodies. This
test can confirm a diagnosis within days of infection. (Regular HIV tests don't work this
soon after infection; they can only detect antibodies.) You may be given
anti-HIV drugs to take for a prescribed period of time. There may be unpleasant
side effects to these drugs, but they may stop HIV from infecting you.
Most people don't know
they've been infected with HIV, but weeks later they may experience the
symptoms of seroconversion. These symptoms mean the body is trying to fight
HIV.
After the first
seroconversion period, the immune system loses the battle with HIV and symptoms
go away. HIV infection goes into its second stage, which can be a long period
without symptoms, called theasymptomatic (or latent ) period. This
is when people may not know they are infected and can pass HIV on to others.
This period can last 10 or more years.
During this period
without symptoms, HIV is slowly killing the CD4 T-cells and destroying the
immune system. Blood tests during
this time can reveal the number of these CD4 T-cells. Normally, a person has a
CD4 T-cell count between 450 and 1,400 cells per microliter. This number
changes constantly, depending on a person's state of health. For an
HIV-infected person, the number of CD4 T-cells steadily drops, making them
vulnerable to other infections -- and in danger of developing AIDS.
