INITIAL INFECTION OF HIV(WINDOW PERIOD)

The period of time after a person becomes infected with HIV,but before antibodies have been formed is known as WINDOW PERIOD. This period is usually two to three weeks and is rarely longer than three months. The virus is present in the blood. It can be detected by an antigen  test. But antibody test will prove negative. It may be noted that the antibodies developed against HIV within the body are not capable of fighting off the germs.
