What are the AIDS prevention measures

Human beings have known the structure of DNA for a long time, but they have not found an effective way to operate and change it correctly and effectively. Various genetic diseases spread through human reproduction. For a long time, scientists have been looking for operational and efficient tools. Just like editing word articles, modify or replace bad virus gene fragments with genetic defects in DNA through simple operations. At the end of last year, some foreign scientists found that the CRISPR-Cpf1 system can efficiently edit DNA in human cells, but how this tool works and whether it can be optimized has always been a mystery. This study is helpful for human beings to manipulate and change the genes with genetic defects in DNA and prevent the occurrence of major diseases such as AIDS through the correct operation in the field of genetic engineering such as shutdown, recovery, switching and so on.
An introduction to the symptoms of AIDS in several periods
I. symptoms of adult male AIDS in acute phase
There are also some people in the initial stage of infection can appear the initial symptoms of male AIDS, the incidence rate is about 50%, mainly manifested as fever, dizziness, weakness dildo fucking , sore throat, joint pain, rash, systemic superficial lymph node enlargement and other cold-like symptoms, some people can also develop diarrhea. The symptom usually disappears after 1 to 2 weeks adult toys , after which men infected with HIV / AIDS turn into an asymptomatic incubation period.
Second, the latent symptoms of AIDS in adult men
Many people have no symptoms during the incubation period, but few adult men have enlarged lymph nodes and neurological symptoms during the incubation period of AIDS. mainly dizziness, depression, memory loss, movement and language disorders, acute aseptic meningitis lymphadenopathy are also iconic symptoms of the incubation period, which are found in the whole cycle of AIDS infection in a small number of adult men.
III. Symptoms of end-stage opportunistic infection in adult men
There may be obvious fever, fatigue, night sweats, uncontrollable weight loss ("10%), persistent diarrhea, persistent fever (" 38 ℃) for more than 3 months, and clinical manifestations of severe immune deficiency, such as slow cellular immune response, opportunistic infection and malignant tumor, which can affect all systems and organs of the body deep anal dildo , and many pathogens often cause infection and tumor.
The main symptoms of adult male AIDS are above, if you have any questions, you can consult our experts, the symptoms of AIDS can not be used as a basis for diagnosis. This is because these symptoms are not special, not unique symptoms of AIDS, but the possibility of other diseases. Therefore, the health department stipulates that AIDS diagnosis can only be based on AIDS antibody test positive results.
Several specific measures to prevent AIDS
At present, there is no effective vaccine to prevent AIDS, so the most important thing is to take preventive measures. The method is:
one. Adhere to clean their love, do not engage in prostitution, avoid premarital and extramarital behavior.
two. It is forbidden to take drugs and do not share syringes with others.
three. Do not use blood transfusions or blood products without authorization. You must use them under the guidance of your doctor.
four. Toothbrushes, razors best vibrator , razors and other personal items shall not be borrowed or shared.
five. Condom use is one of the most effective measures to prevent disease and AIDS in sex life.
six. Avoid direct contact with AIDS patients' blood, semen, milk and urine, and cut off its route of transmission.
