HIV is a highly dangerous infectious disease caused by infection with the AIDS virus (HIV), a virus that attacks the body’s immune system. It targets CD4 T-lymphocytes, the most important cells in the immune system, and destroys them in large numbers, causing the body to lose its immune function. The incubation period of HIV in the human body is 8-9 years on average, and people can live and work without any symptoms for many years before they develop AIDS.
Transmission route
HIV transmission is mainly through sexual intercourse and the exchange of body fluids. Body fluids include semen, blood, vaginal secretions, breast milk, cerebrospinal fluid, and brain tissue in people with neurological symptoms. Other bodily fluids, such as tears, saliva and sweat, are present in small amounts and do not generally cause HIV transmission. The possibility of HIV transmission from saliva is very small.
1.Sexual intercourse transmission;
2.Blood transmission ;
3.Transmission by sharing needles;
4.Mother-to-child transmission;
5.Discovery of new ways.
According to the latest research by experts from the Department of Infectious Diseases of the Union Hospital, the tear ducts or tear fluid may become a new “stronghold” for HIV. This means that HIV may be transmitted through tears.
It is important to note that AIDS is not transmitted through mosquito bites.
Hazards
1.The harm to individuals
Physiologically speaking, once HIV-infected people develop into AIDS patients, their health condition will deteriorate rapidly, and patients will have to suffer great physical pain and eventually be taken away from life.
Psychologically and socially, once a person infected with HIV knows that he or she is infected with HIV, there will be great psychological pressure. In addition, HIV-infected people are easily discriminated by the society, and it is difficult to get the care and attention from friends and relatives.
2.Harm to family
The discriminatory attitudes of the society towards people with HIV and infected people will affect their families, and their family members will have to carry the same heavy psychological burden as they do. This may lead to family discord and even family break-up.
Because most AIDS patients and infected persons are at the age of supporting their families, they are often the main source of financial support for their families. When they themselves can no longer work and need to pay high medical bills, their family’s economic situation will quickly deteriorate. Families with AIDS patients generally end up with orphans left unsupported or parents left unsupported to die.
3.The harm to the society
AIDS mainly affects adults between the ages of 20 and 45 who are the productive members of society, the breadwinners of families, and the defenders of the nation. AIDS weakens social productivity, slows economic growth, lowers life expectancy at birth, reduces the quality of the nation, and weakens national power. Social discrimination and unfair treatment push many people with AIDS and infected people into society, causing social instability, increasing crime rate, and destroying social order and social stability.
4. Impact on children
AIDS has orphaned millions of children, forcing millions of innocent children to suffer the pain of losing their loved ones and often enduring discrimination, school failure, malnutrition and excessive workloads.
