The clinical presentation of whether or not you are infected with HIV is very complex. The incubation period after HIV infection is long, generally considered to be 2 to 10 years, and as short as a few months.
How can you tell if you are infected with HIV? The following clinical manifestations of yourself should be well symptomatic, and then you should take active measures.
1, on the concept of incubation period and window period: (1) window period: refers to the time required from the infection of HIV to the formation of antibodies. The average time for the human body to produce serum antibodies after HIV-1 infection is 45 days, or less. Generally, HIV antibody positivity appears around 5 weeks after infection. The time to develop positive serum antibodies after sexual intercourse infection is 2 to 3 weeks. The length of the domestic window period has not been determined.
(2) Incubation period: It is the time from the time of HIV infection to the appearance of AIDS signs and symptoms. The average adult 29 months, individuals may exceed 5 years, up to 14.2 years, the shortest only 6 days is the acute case of infection due to the importation of blood products. Patients with HIV in the incubation period are an important source of infection.
2, HIV infection clinical staging: After HIV infection, due to different cellular immune status, clinically can be divided into acute infection stage, asymptomatic HIV stage (AC), AIDS-related syndrome (ARC), complete AIDS.
(1) Acute infection stage: 2~6 weeks of infection, a series of clinical symptoms of acute HIV infection appear, but the laboratory test is negative for HIV antibody. The symptoms last for 1~4 weeks to resolve on their own. Thereafter, a relatively healthy asymptomatic incubation period of varying length occurs clinically.
(2) Asymptomatic phase: After the acute infection period has passed, the asymptomatic phase enters, with no clinical symptoms. However, the laboratory serum is HIV-positive. HIV is present in the blood during this period, which is the most dangerous source of infection.
(3) Pre-AIDS: Patients have fever, malaise, night sweats, diarrhea, with weight loss and generalized superficial lymph node enlargement. Serum anti-HIV antibody Y positive.
(4) AIDS stage: Significant decrease in immune function of the body, aggravation of the symptoms of the course, positive serum anti-HIV antibody, significant decrease in CD4-T lymphocyte count, prone to various opportunistic infections and malignant tumors.
