What is the rash of AIDS?
AIDS rash is different from ordinary rash, so what is AIDS rash like?
Aids rash can appear in two stages of the course of AIDS, namely the first acute stage and the third AIDS stage. The rash in the acute stage can be macula, papule or acne-like, especially on the upper chest and back. The damage of rash is rough, but generally there is no feeling of pain or itching, and the skin lesions of mouth and genitals are more common. The rash in the third phase of AIDS is caused by various opportunistic infections, so its rash characteristics depend on what infections, such as protozoan infection, viral infection, bacterial infection, fungal infection, tumor, etc., can cause rash.
Herpes zoster in AIDS patients is often a precursor to AIDS. Herpes mostly occurs in intercostal nerve and trigeminal nerve, accompanied by severe pain, ulcer, hemorrhagic necrosis or blister-like. Infection by other pathogens can lead to rashes corresponding to other pathogens. Because the immunity of HIV-infected people is very low, the rash may last and the symptoms will be worse.
The difference between AIDS rash and eczema
AIDS rash and eczema are sometimes confused, so what is the difference between AIDS rash and eczema?
AIDS is a common infectious disease, mainly transmitted through sexual contact. Caused by HIV infection, various opportunistic infections or malignant tumors can occur. At the initial stage of infection, patients are prone to some rashes, which are not specific and can take many forms, such as desquamation, dryness, itching, herpes, erythema, papules and so on. There is no obvious difference with common eczema.
Because the rash of AIDS is not specific, it is impossible to diagnose AIDS through the rash. It is necessary to screen for HIV antibodies and then diagnose AIDS. Only in this way can we diagnose AIDS. Once diagnosed with AIDS, active antiviral treatment should be given as soon as possible.
The difference between AIDS rash and urticaria
Aids rash and urticaria are both skin diseases, so what is the difference between AIDS rash and urticaria?
Aids rash is generally a small black spot, slightly higher than the skin, which occurs in the neck and occasionally in the chest and back. For people with fair skin, the rash is dark red or reddish brown; People with dark skin have purple or black rashes. Papular urticaria is a common allergic skin disease in infants. The occurrence of this disease is related to insect bites. Rash mostly occurs on the extended side of trunk and limbs. The rash is a slightly spindle-shaped red air mass with different sizes, and there are often small blisters at the top of the rash.
Some patients have no clinical symptoms at the initial stage of HIV infection, but most of them can have clinical symptoms caused by HIV viremia and acute injury of immune system from 6 days to 6 weeks after HIV infection. The initial symptoms of AIDS are mainly persistent and extensive lymphadenopathy, especially cervical lymph nodes, axillary lymph nodes and inguinal lymph nodes. The diameter of lymph node enlargement is about 1 cm, which is hard, painless and movable for more than three months.
What are the characteristics of AIDS rash?
Many AIDS patients will have rashes. Specifically, what are the characteristics of AIDS rash?
If it is the onset of AIDS, tinea corporis may appear more serious than ordinary people, and there may be scaly erythema and herpes with clear boundaries, and sometimes even generalized herpes. There is also severe seborrheic dermatitis, with scales and erythema on the nose and scalp, and scales are more serious than normal people. There is also a performance similar to syphilis rash, which will appear on the trunk or palm and sole without any symptoms. During the onset, if left untreated, the rash will become more and more serious and generally will not heal itself. Therefore, it is necessary to go to the dermatology department for targeted treatment of pathogens, and the rash will gradually improve.
If it is viremia: at this time, the characteristics of rash are not specific, which may be systemic maculopapules, local erythema and papules. Generally, there are no conscious symptoms, and it is neither itchy nor painful. If left untreated, it will subside after about 1-3 weeks.
