Is lip blistering AIDS? Lip blistering is not necessarily AIDS, lip blistering may be cold sores, and the diagnosis of AIDS depends on laboratory diagnosis.
The symptoms of AIDS are different according to different periods. The incubation period from HIV infection to AIDS development varies from several months to 17 years, with an average of 8 years. Because various opportunistic infections and malignant tumors often occur in the late stage of HIV infection, according to the acute, asymptomatic and AIDS stages of cancer diseases, the clinical manifestations of AIDS symptoms are diverse.
1, acute phase
The early symptoms of AIDS are mainly symptoms of upper respiratory tract infection, such as fever, fatigue, sore throat, general malaise, etc., including headache, rash, meningoencephalitis or acute polyneuritis; There are swollen lymph nodes in the neck, axils and occipital region, which are similar to infectious mononucleosis and hepatosplenomegaly.
2. Asymptomatic period
Clinical symptoms and signs are often absent. It is not easy to detect HIV antigen in blood, but HIV antibody can be detected. The duration of this period is generally 6-8 years. In the asymptomatic period, due to the continuous replication of HIV in infected people, the immune system is damaged, and the CD4+T lymphocyte count gradually decreases, which is also contagious.
3. AIDS period
This period is mainly characterized by HIV-related symptoms, opportunistic infections in various systems and tumors. HIV-related symptoms are:
(1) Fever, night sweats and diarrhea lasting 1 month or more;
(2) Weight loss often exceeds10%;
(3) Some patients have neuropsychiatric symptoms such as memory loss, apathy, personality change, headache, epilepsy and dementia.
(4) Persistent lymphadenopathy, characterized by lymphadenopathy in two or more sites except groin; Lymph node diameter? 1cm, no tenderness and no adhesion; The duration is more than 3 months.
The common opportunistic infections are oral Candida infection, Pneumocystis carinii pneumonia, cytomegalovirus infection, toxoplasmosis, cryptococcal meningitis and rapidly progressing active pulmonary tuberculosis. Malignant tumors are usually Kaposi's sarcoma and lymphoma of skin mucosa.
The probability of HIV infection Unsafe sex is the most dangerous and high-risk behavior that is most susceptible to HIV infection, including heterosexual sex and homosexual sex. There is a certain probability of HIV infection, and the probability of infection is different according to different sexual behaviors.
1, HIV infection rate from female to male: female to male 1/700- 1/3000.
2. HIV infection rate from male to female: male to female 1/200- 1/2000.
3. Probability of HIV infection among men: The risk probability of male-to-male transmission is110 to11600.
Although many people don't think that the risk of sexual contact with AIDS is particularly high from the data point of view, many other factors in real life will increase the probability of AIDS infection. For example, those infected with AIDS in the early stage and those in the late stage are the most contagious, and the infection probability is110-1/20, because the virus content in infected people is the highest at this time. The second peak period of infection is when the asymptomatic period is coming to an end and the clinical period is coming. The infection probability is1100-1/200, and the infection probability in the asymptomatic period is11000.
