The incubation period of HIV
The human immunodeficiency virus (HIV) is athe causative agent of HIV infection. The disease begins with the moment of infection of a person and lasts until his death. The time from infection to the first signs is the incubation period of HIV.
Development of infection
For HIV infection, development is characterized asthe perennial course of the disease with the growing destruction of the immune system, which leads subsequently to the development of oncological and opportunistic diseases.
The course of the disease includes several stages: the incubation period of HIV, the stage of early clinical manifestations, the latent stage, the stage of development of secondary diseases and the terminal period (AIDS).
A person infected with a virus is contagious at allstages of the development of the disease. But he presents a special danger during the acute course of the disease and during the terminal terminal stage. At this time there is a progressive multiplication of the virus.
Ways of infection
You can be exposed to HIV from a previously infected person during sexual intercourse, namely, if the condom is misused. This is the most common method of infection.
There is a possibility of infection through saliva during a kiss or oral sex. But this is permissible in the presence of damage to the mucosa, there is a risk of infection through the blood.
There is an opportunity to get HIV through the blood: through a transfusion procedure, through untreated medical instruments, for example, by using a single syringe with an infected person, which often occurs in addicts.
Infection is transmitted during pregnancy and childbirth from an infected mother to a child, as well as breastfeeding.
The infection is not transmitted by the household method, because HIV-bacteria are very resistant to the environment and die in it after a few hours.
The incubation period of HIV infection
After the momentinfection occurs incubationthe period of HIV. The duration of the incubation period for each person is individual - from two weeks to a year and depends on the state of human immunity. As the statistics show, the average duration is three months.
HIV infection, penetrating into the human body,It causes a response in the form of the appearance of antibodies to the pathogen. The incubation period of HIV is the interval between the introduction of the virus and the appearance of antibodies to it.
Then the stage of early clinical manifestations begins, when the first symptoms of HIV infection begin to appear, similar to the signs of respiratory diseases:
- enlarged lymph nodes;
- malaise, drowsiness;
- pain in the eye socket, photosensitivity of the eyes;
- rashes and various rashes on the skin;
- a runny nose, cough.
These symptoms spontaneously take weeksin two - four, after which there is a period of latent course of the disease, which is delayed for many years. On average, the life expectancy of an HIV-infected patient lasts 12 years. In most cases, this is the period of remission of the disease.
The next stage is the period of secondary diseases,which is accompanied by the manifestation of concomitant diseases that do not harm a person with a healthy immune system. Developing diseases begin to destroy the body from the inside.
The next and last stage of development is AIDS,lasting from 0.5 to 2 years. At this stage, the central nervous system, the intestine, the lungs, the mucous membranes, the skin are most affected. Viruses and bacteria are activated, which do not bring any harm to humans before. It is these reactions of the body that cause the death of a person.
At the moment, treatment has not yet been developed,eliminating HIV infection from the body. Modern methods are based on highly effective antiretroviral therapy, which slows down and stops the course of infection, as well as its further transition to the last stage. This allows the HIV-infected person to fully live.
Together with the prescribed therapy, an important placehas the health of the carrier virus. To do this, recommend proper nutrition, avoidance of stressful situations, a good and healthy sleep, prolonged exposure to the sun, rejection of bad habits, sports loads, as well as constant examination (2 - 4 times a year) for specialist doctors.
