The full name of AIDS is Acquired Immunodeficiency Syndrome, or AIDS, which is an infectious disease caused by HIV infection that poses a great danger to human beings, and is mainly transmitted through blood, sex, and mother-to-child transmission. AIDS cannot be acquired congenitally, but is caused by acquired HIV infection, so it is clinically known as Acquired Immunodeficiency Syndrome (AIS). When HIV infects the human body, it mainly attacks the T-lymphocytes of the human body, resulting in an obvious defect in immune function, which may lead to a series of symptoms. Usually, the clinical symptoms of HIV infection are not typical at the initial stage, for example, some patients may only show cold, fever, generalized weakness, and some patients may suffer from obvious weight loss, etc. However, some patients may have no obvious symptoms and enter the asymptomatic stage of infection. As the disease progresses day by day, the symptoms of AIDS will become more and more obvious, and some patients may develop systemic range of infection, such as the emergence of bacterial pneumonia, tuberculosis, herpes simplex virus infection, herpes zoster virus infection and so on, and the patients are also susceptible to diseases such as Kasibol sarcoma, lymphoma and so on, after the invasion of HIV into the human body, it will destroy the immune function of the human body, and it is prone to many kinds of infections and tumors, which may ultimately cause the The patient may eventually die. The initial symptoms of HIV are not obvious and are not exactly the same for each patient. If there is high-risk sex, unclean injections, etc., followed by fever, etc., you should go to the hospital in time to see a doctor to clarify whether there is HIV infection. There is no cure for HIV, but active treatment can prevent the disease from progressing further.
