Aids, fully known as acquired immune deficiency syndrome (aids). It is a vicious epidemic with a very high mortality rate caused by hiv, the human immunodeficiency virus (hiv)。
When the hiv virus enters the human body, the cd4+t lymphocytes, which are the primary cause of death, are gradually reducing resistance, causing many complications that are difficult to cure and leading to death。

Paths to aids transmission
Sexual transmission
This is the world's leading route to aids. The greater the number of partners, the greater the chances of contracting aids。
Blood transmission
The importation of blood or blood products infected with hiv; the sharing of hiv-contaminated, unsterilized needles and syringes among intravenous drug addicts; and the sharing of other medical devices or household appliances (e. G., toothbrushes, razor blades with infected persons) can also be transmitted through damaged, but rare。
Mother-to-child transmission
Women infected with hiv may also transmit hiv to the foetus or infant through pregnancy, childbirth and breastfeeding。

Aids “warning light”
At the initial stage of the hiv infection, patients may suffer from the following symptoms: heat, throat pain, lymphoid swollenness and fatigue, similar to common flu; possible red or purple spots, rashes or rashes on skin; headaches, muscles and joint pain. It is easy to ignore, and this period is known as “the acute hiv infection period”。
As the time of infection and the number of viral infections increases, the patient's immune system is gradually severely damaged, with various opportunistic infections and tumors ...

Aids prevention
(1) prevention of blood transmission
Drug use is strictly prohibited and syringes are not shared。
There is no unauthorized blood transfusion and use of blood products。
Do not borrow or share personal effects such as toothbrushes, razor blades, razors, etc。
Direct contact with the body fluids of aids patients is to be avoided and their transmission cut off。
(2) preventive means of dissemination
(c) to minimize participation in alcohol-based gatherings, where alcohol is less frequently used, in order to avoid “drinking out of control” behaviour。
To minimize access to entertainment places such as “bars” and “jump-di” and to avoid receiving cigarettes, drinks, etc. From unfamiliar people, which may contain drugs of addiction。
Sexual intercourse requires the correct use of condoms at all stages in order to avoid hiv infection。
(3) testing and treatment
Timing: an infection can be detected through nucleic acid tests within one week of the high-risk behaviour and an antigen test can be selected for three to four weeks。
The value of treatment: timely antiretroviral treatment reduces the load to an untested level, significantly reduces the risk of transmission and increases life expectancy。
In the event of high-risk behaviour, the risk of infection can be significantly reduced by taking drugs off within 72 hours, with the best effect in two hours。
