Syndrome

History AIDS originated in Africa, after the immigrants i

History

Symptoms Higher incidence in young adults, age of onset

of 80% in 18 to 45 years, that is more active sex life ages. After HIV infection often suffer some rare diseases such as Pneumocystis carinii pneumonia, toxoplasmosis, atypical mycobacterial and fungal infections.

Symptoms After HIV infection, the first few years to 10

years may have no clinical manifestations. Once the development of AIDS, the patient can be a variety of clinical manifestations.

Symptoms:Stage 1 Early symptoms are like the common cold, flu-

like, may have general fatigue, weakness, loss of appetite, fever, etc.,

Symptoms:Stage 3 After gradually violations visceral organ,

unexplained persistent fever, can be up to 3 to 4 months.

Prognosis1. Acute infection usually two to six weeks after infection occurs, symptoms like flu, then the symptoms disappear soon. This period can detect HIV antigen, but not detect HIV antibodies.

Prognosis 2. Asymptomatic infection (incubation period) si

nce infected with HIV to develop into AIDS patients, this period is called the incubation period. Individual differences incubation period, short to less than a year, grow to up to 15 years, an average of 5 to 7 years. More than two no obvious symptoms, can not tell from the outside, so that the people called infected. If not treated, the average after 7 to 10 years will develop into AIDS.

Prognosis 3. HIV incidence of HIV infection when the imm

une system has been severely damaged, can not maintain the minimum resistance to disease when it appeared difficult to cure a variety of symptoms, become AIDS. After becoming AIDS, usually die within six months to two years.

Diagnosis 1.Acute phase Patients near future epidemiological and clinica

l manifestations, combined with laboratory HIV antibody from negative to positive can be diagnosed, or only laboratory tests HIV antibody from negative to positive can be diagnosed. About 80% HIV infection six weeks after infection screening test can detect antibodies, almost 100% after 12 weeks of infection can be detected antibodies, only a very small number of patients after infection within three months or six months after the detection .

Diagnosis 2.Asymptomatic period Diagnostic criteria: epidemiological history, co

mbined with HIV positive can be diagnosed, or only laboratory tests can be diagnosed HIV positive.

Diagnosis 3. AIDS stage (1) unexplained persistent irregular fever above

38 ,> 1 month;℃ (2) the number of chronic diarrhea more than 3

times / day,> 1 month; (3) within six months of weight loss of more than

10%; (4) PCP; (5) recurrent bacterial pneumonia; (6) deep fungal infections;

Spread MTCT: mother and baby

Sexually transmitted

Blood transmission

Treatment Treatment goal at this stage is: to maximize

and lasting reduction in viral load; get immune reconstitution and maintenance of immune function; improving the quality of life; reduce HIV-related morbidity and mortality.

Treatment Treatment of this disease emphasize

comprehensive treatment, including: general treatment, antiviral therapy, restore or improve the treatment of opportunistic infections and malignancies and treatment of immune function.

Treatment 1. General treatment

For HIV infection or acquired immunodeficiency syndrome patients are not required to be treated in isolation. Asymptomatic HIV infection can still maintain a normal work and life. Antiviral treatment should be carried out according to the specific condition, and closely monitor changes in the disease. Early development of AIDS or AIDS patients, according to the disease should pay attention to rest, to give high-calorie, multi-vitamin diet. You can not eat, should be intravenous infusion nutrition. Strengthen the supportive therapy, including blood transfusions and nutrition support therapy, maintaining water and electrolyte balance.

Treatment 2. antiretroviral therapy Antiviral therapy is the key to AIDS treatment.

With the introduction of highly active antiretroviral combination therapy applications, greatly improving the anti-HIV effect, significantly improves the quality of life and prognosis.

Prevention 1. adhere to be sure that no prostitution, prostitution, a

void premarital, extramarital sex.

2. prohibited drugs, do not share syringes with others.

3. Do not use unauthorized blood transfusion and blood products to be used under a doctor's guidance.

6. To avoid direct blood, semen, breast milk and urine contact with AIDS patients, cut off its transmission.

Cure So far no cure. HIV damage a direct result of human death,

but it destroys the body's immune system, susceptible to other diseases. Then death.
