The early symptoms of AIDS have got AIDS, and I regret it. After the high risk, I was afraid. When the human body is infected with HIV for a period of time, the human body will not immediately notice it, and may even have no symptoms for several years, and looks like a healthy person. The longest incubation period of HIV is 7~ 10 years.
Usually, after infection 1~2 months, there will be obvious symptoms, which are caused by viruses: lymphadenopathy is a common symptom, followed by rash, muscle aches, night sweats, low fever, sore throat, fatigue, lethargy, weight loss and so on. Weight loss is also an obvious indication to consider infection. Some people can lose 65438 weight in a short time.
Why can't drugs be cured? This should start with the characteristics of HIV. HIV attacks T lymphocytes with CD4 receptor in human body. Once it successfully attacks cells, it will be out of control, and cells will become the natural reservoir of HIV. Once HIV invades human cells, the virus will be integrated with the cells and will be difficult to remove for life. Random dormancy and random replication have really turned important cells of the immune system into factories for making viruses. CD4 T cells are one of the most important immune cells. If these cells are destroyed, the whole immune system will be fatally attacked, almost completely paralyzed, and the body will lose its resistance to various diseases. Not to mention fighting HIV, the consequences can be imagined.
At present, drug therapy can only reduce the amount of virus in the body to the maximum and permanently, and try to rebuild the immune function of the body. Through drug control, most AIDS patients can improve their quality of life, the mortality rate is greatly reduced, and the life expectancy of most patients is the same as that of normal people.
Why can't vaccines be prevented? HIV vaccine was first developed in the early 1980s. Up to now, it has been nearly 40 years, and there is still no effective product. Other major infectious diseases have basically been vaccinated, and they have achieved very good protection effects. Some, such as polio, have even been basically extinct. Why is it so difficult to develop an AIDS vaccine?
In fact, the vaccine preparation process itself is not difficult. The difficult thing is to find the right antigen on HIV, find the right antigen, and then prepare the vaccine. After injection, the human body produces antibodies, which can neutralize these antigens and achieve protection. And what about reality? HIV is too cunning. The appearance of HIV is spherical, and some protein components on the surface are very easy to mutate. It may just be designed to capture a protein antigen, but as a result, it mutates again, and the antibody produced by the old antigen can't recognize it. Protein in the virus has little variation, but it is tightly wrapped. Even if a suitable vaccine is designed and antibodies are produced, it is difficult to reach the inside of the virus.
Some time ago, it was reported that the United States developed a new AIDS vaccine. It is reported that monkeys vaccinated with this new vaccine can avoid being infected by a virus similar to human HIV. At present, there is no virus attack test in this study, that is to say, although antibodies have been produced in monkeys, whether these antibodies can effectively fight against human HIV virus needs further experimental verification. You know, the previous 40 years of research and development failed because only enough antibodies could be produced, but there was no protection or the protection rate was too low. So this vaccine probably failed again.
The story of human and monkey about HIV is about the origin of human infection with HIV. Now it is generally believed that it is from orangutans. Orangutans are infected with SIV, while people are infected with HIV. HIV is the result of SIV mutation. But the difference is that SIV infection in natural hosts is not pathogenic in many cases.
The natural host of SIV, like wild chimpanzees, can be infected by SIV, showing symptoms similar to human infection with HIV, while mangabey with white top is not the host of SIV, so it will not cause disease.
There used to be a movie, which was quite interesting. Roughly speaking, in a primitive tribe, men in the tribe have a special hobby besides having sex with women in their own tribe, that is, they like to imprison female monkeys, put lipstick on them, make up, and force them to pose all kinds of enchanting movements to make tribal men have fun. This process also explains to some extent why people are infected with AIDS in their early years. Of course, eating related animal meat raw is also one of the reasons.
Emergency self-rescue within 72 hours of suspected HIV infection can be completed with related drugs, such as reverse transcriptase blockers, which is one of them.
Secondly, if you suspect that you are infected and want to have an examination, you should be reminded that there is a window period for HIV infection. That is to say, if you suspect that you are infected or do something you shouldn't do, you need a blood test, which may not be detected within 2 to 6 weeks, because your body has not produced enough HIV antibodies at this time, and the current testing methods can't be qualitatively tested, so the result is likely to be negative. Out-of-window testing can indeed rule out the possibility of HIV infection.
About 80% of HIV-infected people can be detected by primary screening at 6 weeks after infection, almost 100% of HIV-infected people can be detected at 12 weeks after infection, and only a few patients can be detected within 3 or 6 months after infection. When you are passionate, don't ignore the risks. If you catch it, you will carry it with you all your life, and your life may be handed over to the virus!
