What you must know about AIDS Day-the way of transmission

It is mainly transmitted through body fluids. Body fluids include blood, semen, vaginal secretions, milk, cerebrospinal fluid and brain tissue of people with neurological symptoms.

Other body fluids, such as tears, saliva, sweat, etc., can detect the virus, but the number is small and generally does not lead to transmission. The identified routes of infection include:

1. Sexual transmission: HIV can be transmitted through sexual intercourse. Genital diseases (such as syphilis, gonorrhea, condyloma acuminatum) or ulcers increase the risk of viral infection.

There are a lot of viruses in the semen or vaginal secretions of HIV-infected people, and anal sex and vaginal sex can spread the virus.

2. Blood transmission: blood transfusion transmission: If there is HIV in the blood, people who input this blood will be infected. B. Spread of blood products: Some patients (such as hemophilia) need to be injected with biological products made of certain components extracted from blood.

3.*** Transmission through needles: Using unclean needles will spread HIV from one person to another. For example, intravenous drug users use needles; Needle, needle, etc. Be reused in the hospital.

4. Mother-to-child transmission: If a mother is infected with HIV, she is likely to infect her child during pregnancy, childbirth or breastfeeding.

However, if the mother receives relevant treatment during pregnancy, the chances of the baby being infected with HIV may be much lower, or even completely healthy. But mothers infected with HIV must never breastfeed their children.

Dental surgery, fighting, using toothbrushes and razors, hardware cutting and other bleeding industries are actually a kind of blood contact infection.

Three knowledge definitions that AIDS Day must know.

AIDS is a very harmful infectious disease, which is caused by HIV infection. HIV is a virus that can attack the human immune system.

It takes the most important T lymphocytes in the human immune system as its main target, destroys it in large quantities, and makes the human body lose its immune function.

Therefore, the human body is susceptible to various diseases, malignant tumors can occur, and the mortality rate is very high. The average incubation period of HIV in human body is 8 ~ 9 years. Before you get AIDS, you can live and work for many years without any symptoms.

What you must know about AIDS Day: Four Symptoms

Aids occurs mostly in young adults, and the onset age is 80% at 18-45 years old, that is, the age of active sexual life. After HIV infection, there may be no clinical manifestations in the first few years to more than 10 years. Once AIDS develops, patients will have various clinical manifestations.

1. General symptoms: persistent fever, weakness, night sweats and persistent lymphadenopathy. Especially in the neck, armpit and groin, the lymphadenopathy is more obvious. The diameter of lymph nodes is larger than 1 cm, and the texture is solid, movable and painless.

The weight loss can reach more than 10% within 3 months, and can be reduced by up to 40%, especially suitable for emaciation patients.

2. Respiratory symptoms: long-term cough, chest pain, dyspnea, and blood in sputum in severe cases.

3. Gastrointestinal symptoms: loss of appetite, anorexia, nausea, vomiting, diarrhea, and bloody stool in severe cases. Drugs commonly used to treat digestive tract infections are ineffective against this kind of diarrhea.

4. Symptoms of nervous system: dizziness, headache, slow response, mental retardation, mental abnormality, convulsion, hemiplegia, dementia, etc.

5. Skin and mucosal damage: herpes simplex, herpes zoster, oral and pharyngeal mucosal inflammation and ulcer.

6. There are many malignant tumors in the tumor. Kaposi sarcoma located on the body surface can be seen with red or purple spots, papules and invasive masses.

Why is the incidence of AIDS getting higher and higher?

1, an open sexual concept

With the opening of society, the development of progressive network and the influence of western culture infiltration, many young people are becoming more and more open in sex, and most college students have premarital sex. However, due to the lack of sexual protection measures, many students did not take corresponding protective measures during sexual life, leading to virus invasion.

2. Lack of sex education

At present, the concept of sex is gradually opening up, but some of it is still bound by traditional concepts. In addition, China does not pay enough attention to the popularization of sex education knowledge. In life and school, teachers and parents will avoid sex education. Therefore, most young people know little about the prevention of sexually transmitted diseases, do not do a good job of self-protection, and do not take protective measures during sexual life.

Empty nesters are lonely.

According to most people's cognition, middle-aged and elderly people don't need sex. On the one hand, it is believed that the sexual desire of the elderly decreases with age, on the other hand, they have children and a stable life, and sex life has nothing to do with them. Therefore, the physiological needs of many elderly people can not be expressed, especially the widowed empty nesters. With the increase of emptiness and loneliness, the elderly become blind to sexual needs, but they will not protect themselves during sexual life. Frequent high-risk sex will lead to an increase in the risk of infection and the probability of AIDS among the elderly will gradually increase.

4. Sexual life disorder

With the opening of sexual concept, many young people not only have one sexual partner, but also change sexual partners frequently, and have unhealthy sexual behavior, especially having sex with wounds, which increases their risk of HIV infection.

Warm reminder, if you want to reduce the incidence of AIDS, you must start from yourself, maintain good sexual behavior, wear condoms, and avoid cross-infection of viruses. Besides, you won't use personal items such as syringes, needles and razors with others every day. If you want to have an operation, choose a regular professional doctor. And refuse to take drugs and other illegal acts, do a good job of correct prevention and keep yourself away from AIDS.
