得了艾滋病自然发病的四个阶段

AIDS had four stages of natural disease

Keywords: symptoms of AIDS AIDS AIDS AIDS in the early detection of symptoms of aids AIDS AIDS AIDS Day HIV latency

AIDS complete process is divided into four phases: acute infection period, incubation period, pre-AIDS, a view typical of AIDS.

Not everyone infected with the emergence of four will complete the performance, but each disease stage of all patients seen in clinical practice. Four different clinical manifestations of the period is a gradual and consistent course of the development process. China's sexual health network

1, the window period of acute infection is also the time period. HIV attacks the human body to stimulate the body caused by the reaction. Patients with fever, rash, swollen lymph nodes, but also occurred in fatigue, sweating, nausea, vomiting, diarrhea, pharyngitis, etc.. Some acute aseptic meningitis, manifested as headache, nerve disorder symptoms and meningeal irritation. Peripheral blood examination, the total number of normal leukocytes, or lymphocytes decreased monocyte increase. Period of acute infection, the symptoms often relatively minor, easily ignored. When the whole body, such as symptoms of fever after about five weeks, serum HIV antibody positive. Since then, the clinical duration ranging from a relatively healthy, asymptomatic incubation period.

2, the incubation period can be infected without any clinical symptoms, but the latency is not quiescent, but not the security phase, the virus continues to reproduce, with a strong role in the destruction. Mean incubation period from HIV infection until the emergence of AIDS Clinical symptoms and signs of time. The average incubation period of AIDS is now considered to be 2-10 years. This early detection and prevention of patients have caused great difficulties.

3, pre-AIDS began to appear after the incubation period of AIDS-related symptoms and signs, until the development of AIDS as a typical period of time. This period, there are many names, including AIDS-related syndrome, SARS-related lymphadenopathy, persistent generalized lymphadenopathy, AIDS syndrome, such as the former. At this time, AIDS patients have the most basic features, namely, cellular immune defects, but no more than minor symptoms. The main clinical manifestations are:

A. Lymph nodes in this period one of the most important clinical manifestations. Mainly superficial lymphadenopathy. Part of which occurred mostly in the head and neck, armpits, groin, neck, ears ago, the ears, the shares lymph nodes, submandibular lymph nodes and so on. General at least two or more parts, some as many as a dozen Department. Swollen lymph node on the general treatment of non-response, often sustained for more than six months or more nodes. About 30% of patients with clinically superficial lymph nodes only, without other systemic symptoms.

B, patients often have systemic symptoms of viral general malaise, muscle pain and other symptoms. About 50% of the patients have low cyclical weakness and fatigue, often continuing for several months. Night sweats, in January with more than 5 times. About 1 / 3 of patients more than 10% weight loss, such weight loss can not be explained simply by heat, add enough heat not be able to control this weight loss. Some patients with headaches, depression or anxiety, and some sensory nerve endings lesions appear, may be associated with HIV-related violations of the nervous system, and some may be reactive mental disorders. 3 / 4 of patients may be splenomegaly.

C, a variety of infections in this period apart from the superficial lymph nodes and systemic symptoms, the patients with a variety of special nature or recurrent non-fatal recurrent infections. Repeatedly infected with the disease will accelerate development of AIDS disease to enter the typical period. About half of the patients have more serious athlete's foot, usually unilateral, and the lack of an effective local treatment of the reaction, the patient's armpit and groin site aureus infection often bullous kitchen septic sores, patients with perianal, genital, weight location and occurrence of oral condyloma acuminatum and verruca vulgaris often infected with a virus. Oral herpes simplex and herpes zoster of the chest than normal incidence of a marked increase in the crowd. Oral bacteria also read quite common, mainly for the oral mucosa erosion, hyperemia, and cheese-like cover.

Other common non-streptococcal pharyngitis infection, acute and chronic sinusitis and intestinal parasitic infections. Many patients the increased frequency of defecation,-thinning, with mucus. May be associated with proctitis and a variety of pathogenic microorganisms on the invasion of the intestinal tract. In addition, oral hairy leukoplakia can occur, the existence of hairy leukoplakia is an important early clues to diagnosis of AIDS.

4, a typical period of AIDS, some scholars called for the death of AIDS, HIV infection is the final stage. This period has three basic characteristics:

Serious defects in cellular immunity.

Occurred in a variety of fatal opportunistic infections.

Various malignant tumors.

The end of AIDS, the total collapse of immune function, patients with serious syndrome, until death.

AIDS diagnosis can not rely on clinical manifestations, the most important thing is to check the basis of the blood test results are positive, so after suspected HIV infection should be their own in time to the local health inspection and quarantine departments to do, do not own under the diagnosis of disorder.
