I believe everyone is familiar with AIDS. As an infectious disease, it was once a topic of conversation, because it has a powerful destructive force on human immunity, and it also poses a huge threat to the health and even life of patients. Therefore, it is necessary to understand and prevent AIDS.
01
Don't mistake AIDS for a skin disease
I have seen an AIDS patient before. The patient was a 68-year-old man who was first admitted to the hospital with eczema in the company of his wife.
Although the patient strongly stated that he was eczema, and asked to prescribe some medicine for eczema. But occupational sensitivities tell me that this one doesn't look like eczema.
During the few minutes of the consultation, the patient was irritable and kept scratching his skin. It can be clearly seen that the old wound on his skin has not healed, and the new wound has appeared again.
Sure enough, within a few days, the CDC confirmed the diagnosis and the test result was positive.
Many AIDS or syphilis patients are actually reluctant to admit that they are ill at first. On the one hand, there is a lack of professional awareness of this type of venereal disease.
In addition, some symptoms of AIDS at the beginning may be very similar to skin diseases, which leads many people to mistake AIDS for skin diseases or allergies in the early stage.

Don't mistake AIDS as a skin disease. If these conditions occur in the body, be careful that it is an AIDS signal
- swollen lymph nodes
There are many lymph nodes in the body, but the most common are usually the lymph nodes in the neck, under the jaw, or under the armpit. Swollen lymph nodes can be caused by many reasons, but if the cause cannot be explained, it may also be caused by AIDS.
The swollen lymph nodes caused by AIDS will feel hard and painful to the touch, but the surface skin may be difficult to see, and it looks flat and unchanged.
- suppressive dermatitis
Suppressive dermatitis usually occurs in 1% to 3% of the population and can be as high as 80% in HIV-infected patients. The clinical manifestations are erythematous and desquamative skin lesions, which can be diffuse or localized plaques in the scalp, including the preauricular area and the external auditory canal, the central area of the face, especially the eyebrows and nasolabial folds, and the chin area.
Patients with advanced HIV infection have more severe skin infections and are difficult to treat.
- Infectious skin lesions
After AIDS-infected patients, 20% of them have oral hairy leukoplakia, which is manifested as a slightly raised tunica albuginea and a hairy surface. This is a very specific early sign. The infection rate of herpes zoster in HIV-positive patients is 3% to 4%, and severe generalized herpes can occur.
The incidence of condyloma acuminatum in male infected persons is 40%. The surface is a huge vegetation, highly proliferative, and occurs repeatedly on the penis and perianal skin. Cytomegalovirus infection manifests as nodules, plaques, ulcers, mucous membranes of the oral cavity, pharynx, and tongue, and necrosis in the perianal, rectal mucosa, perineum, thigh, and arm.
03
Several elements of "high-risk HIV exposure"
▲ The HIV virus will die when exposed to the air for 3-5 minutes. The dead HIV virus is not contagious, and HIV must be transmitted through the living HIV virus;
▲ The concentration of HIV virus must reach a certain level to cause infection, and body fluids such as tears, saliva, and urine are not infectious;
▲ HIV transmission must be through the exchange of sufficient high-risk body fluids, such as semen, blood, vaginal secretions, breast milk, rectal fluid, etc.;
▲ HIV infection requires high-risk fluid exchange through skin or mucosal wounds.
04
How do people with HIV detect the disease?
There are three situations in which diseases are found. The first is self-testing, the second is a routine inspection at the hospital every year, and the third is a detailed inspection at the hospital after symptoms appear.
Many people discover the disease in the first case and have been unaware that they have been infected with HIV. When the patient has symptoms, they go to the hospital for examination and treatment. The virus has spread and began to invade various organs of the body, resulting in severe symptoms and complications. Treatment can only temporarily control the condition and prevent further complications.
If the disease is treated before it appears, then AIDS can be effectively prevented. Although there is a potential risk of developing the disease, the cure rate is high and the mortality rate is low.
05
AIDS is completely preventable!
AIDS is a more dangerous and terrifying disease. AIDS is a series of diseases related to the immune system due to the infection of the AIDS virus, which leads to the destruction of the body's immune system, and the whole process is an acquired immunodeficiency syndrome.
AIDS is a very dangerous disease that cannot be cured by current medicine. AIDS can be transmitted through blood contact, X contact infection, mother-to-child infection and other three ways, of which X contact is the most important way of transmission.
Although AIDS is terrible and incurable, the probability of infection is not high, and as long as one can keep oneself clean and avoid high-risk behaviors, it can be effectively prevented.
