HIV (human immunodeficiency virus) is a virus that attacks the body's immune system. More precisely, it targets certain immune cells and kills them. The longer and more active this process lasts, the weaker the immune system becomes - over time, it is simply unable to cope even with infections that are relatively safe for an ordinary person.
HIV and AIDS - differences, duration of development, forecasts
AIDS is the final stage of HIV, which is characterized by severely reduced immunity. It is important not to confuse these two concepts. From the moment of HIV infection, the disease can develop to the AIDS stage without treatment within 9-11 years (on average). Once diagnosed with AIDS without treatment, life expectancy is short - on average up to 19 months.
If you start treatment on time, you can live a very long life at the HIV stage - the life expectancy of such patients thanks to modern treatment is 20-50 years. And although at the AIDS stage the situation is much more complicated, many patients, with proper treatment and a strong body, can live more than 10 years.
It is obvious that taking therapy is the most important factor for treating HIV and living a full, long life. Moreover, it is treatment that can significantly reduce the viral load and make the infected person harmless to the partner, as well as family members.
Diagnosis and treatment of the disease
The virus cannot be eliminated 100%. This is the main negative side. Initially, during the incubation period, the virus does not manifest itself in any way.
diagnosis of HIV infection
Symptoms of HIV infection in men initially appear in an acute form, but it is important not to miss the elimination of symptoms and diagnosis, because the virus quickly switches to the activation phase. There is no need to mix the concepts of HIV and AIDS. HIV is an infectious disease, and AIDS is a serious pathology. Therefore, it is so important to identify the development of the disease at the stage of its development. With early diagnosis and identification of the first symptoms of AIDS, life expectancy ranges from 20 to 50 years. However, if AIDS was diagnosed at a late stage of development and treatment was not prescribed, then it is worth talking about 6-9 months.
Routes of HIV transmission
Main routes of HIV infection:
- unprotected sex with an infected person (the most common route of HIV transmission). You can become infected either after a single contact or after several;
- using a needle to inject drugs after an infected person. Or other variants of situations in which the blood of a healthy person comes into contact with the blood of an infected person;
- transmission from mother to fetus during childbirth or from mother to child during breastfeeding. An important note: if a woman is treated and is under the supervision of doctors, she has every chance of giving birth to a healthy baby;
- transfusion of infected blood. In modern clinics and hospitals this is no longer possible, since all materials undergo very serious testing.
There are also so-called risk groups - these are people who are more susceptible to HIV infection than others:
- people who are promiscuous;
- homosexuals;
- drug addicts who inject drugs;
- people with a partner infected with the virus.
Such people should constantly get tested. In some cases, they are recommended to take preventive medications (only on the recommendation of a doctor).
When talking about how you can become infected with HIV, you should clarify in what cases this is impossible:
- during everyday contacts;
- when using infected utensils;
- with an insect bite;
- when kissing.
Contact with an HIV-infected person at the everyday level (in the family, at work, in other forms of communication) is absolutely safe and does not pose any threat to others.
How to protect yourself
Considering the main methods of HIV infection, doctors identify several simple rules for preventing the problem:
- Avoid casual sex. Most likely, you know a little about the sex life of a potential partner. In any case, use contraception. You can catch a dangerous virus as a result of traditional sex. But is it possible to become infected with HIV through oral or anal sex? Unfortunately, yes, so be as careful as possible.
- Use only new, sterile needles and syringes. This is often neglected by drug addicts, creating optimal conditions for the transmission of the disease. If you are donating blood or are on an IV in the hospital, make sure that the nurses only use new needles and syringes. Their inattention or your false economy are the causes of the problems.
- Be careful in beauty salons. Infection is only possible if the instruments are not disinfected and there is contact with blood. Check the first and contact experienced specialists.
- Be careful with blood transfusions. Trust only trusted medical institutions. Agree to a blood transfusion if there is no other alternative. See for yourself or ask your doctor to look at the donor’s medical record.
- Do not leave open wounds . An antiseptic and a sterile bandage prevent dust and fluids from an infected person from entering the wound. Do not be lazy to treat a small scratch yourself and seek qualified medical help in case of serious damage.
Simple rules can reduce the likelihood of catching a disease to almost zero.
Main stages of the disease
The stages of HIV are divided into the following:
- incubation This is the stage at which infection and subsequent multiplication of the virus in the blood occurs. It lasts up to six weeks, sometimes less. Even if infected, at this stage a person will not see obvious signs, and a blood test will not show that there are antibodies in the blood;
- primary. The first signs of infection may already appear here. The second stage lasts for 3 weeks - at this time antibodies appear, the virus is determined in the laboratory;
- subclinical. The first sign of the disease appears - enlarged lymph nodes. The patient feels completely healthy and does not complain about his health;
- the appearance of secondary diseases. The immune system begins to malfunction, causing a variety of diseases to appear: from frequent colds and candidiasis to pneumonia, tuberculosis;
- terminal. The stage involves exhaustion (rather rapid and progressive), as well as the subsequent death of the patient.
The stages do not have one correct time frame - they may differ from person to person. For example, HIV-infected people often feel well for years or do not pay attention to small signs. The disease is detected only at the stage of severe deterioration in health or through random tests.
Symptoms of HIV
Once you know how HIV is transmitted, you need to understand the symptoms. The problem is that these symptoms appear at an early stage, then disappear and no longer bother the person for a long time - literally for years. They are also very similar to the manifestations of other diseases, which can be misleading.
So, at the first stage, when the virus manifests itself, a person may feel:
- sore throat, fever;
- soreness of the skin, joints, bones4
- chills, fever.
At the same time, the cervical lymph nodes enlarge and various rashes may appear. All this is often mistaken for signs of ARVI or other similar diseases.
New HIV symptoms return after several years of a calm and healthy life. These include:
- severe fatigue, fatigue;
- enlargement of lymph nodes - not only in the cervical, but in several groups;
- weight loss. Usually it looks causeless, the person does not understand what is going on;
- fever, chills, sweating (mostly at night);
- problems with the gastrointestinal tract - usually manifested by loose stools for no apparent reason.
At this stage, as a rule, the disease is detected - because the patient goes to the doctor, and the specialist prescribes an additional examination.

How is HIV diagnosed in Moscow?
There are two tests to diagnose the virus: preliminary ELISA and the most accurate immunoblot. The accuracy of ELISA is about 90%. It is recommended to carry out it 3-6 months after contact with the virus, then it gives maximum accuracy. The usual ELISA test is based on a blood test, but there are also rapid tests that help obtain information based on urine or saliva. Such texts are purchased exclusively at the pharmacy (in no case on the Internet!), since it is necessary to use officially approved products.
If the rapid test gives a positive result, you need to go to an infectious disease specialist yourself. In such a situation, as well as when ELISA in a blood test gives a positive result, the patient is prescribed an immunoblot. Its reliability is already 99.9%. Depending on the diagnosis, the diagnosis is made either on the basis of two repeated tests or a combination of both. The analysis is rechecked and only after this a diagnosis can be made. This is necessary in order to exclude false positive results that may occur during the diagnostic process.
Important: the test does not show how HIV is transmitted in a particular situation - that is, you can determine the route of infection only by analyzing your own actions.
How is diagnosis carried out?
How to detect HIV at home ? In general, diagnosis is carried out on the basis of blood tests - ELISA and immunoblotting. Through the first analysis, the quantitative ratio of the virus in the serum can be determined.
Immunoblotting has greater sensitivity and specificity up to 99.7%. The incubation period for AIDS lasts about three months. To diagnose AIDS, the transcript must demonstrate CD4 lymphocytes in the blood in an amount of no more than 200.
AIDS treatment
HIV treatment
Treatment boils down to prescribing antiretroviral therapy. The patient is given a medication regimen - and it must be followed as precisely as possible, without deviating from the program. Otherwise, the virus may develop resistance to treatment and cannot be further suppressed.
Indicators of quality treatment are a decrease in the viral load, as well as an increase in CD4+ cells in the blood, which indicates the activity of the immune system.
Medicines for treatment are issued in medical institutions, patients are registered and receive medications free of charge, in accordance with the established procedure. Information about the disease is confidential - it is not sent to work, place of study or other places. The patient has the right to keep it secret (if this is not provided for in separate work contracts).
If the rules for taking therapy are followed, the virus in the blood gradually decreases; over time, the patient becomes completely safe for his sexual partner and is not able to infect anyone.
Prevention of HIV infection
The first and most important rule is to be regularly tested for HIV, even if you have not had suspicious contacts. It is recommended to be examined once every six months - especially since there are convenient rapid tests for this.
You also need to be careful when choosing partners. You should not take the word of a person who says that he is definitely not sick - it is better to ask for the results of the study and see for yourself that you can trust him. But remember that within six months even contaminated blood may not give positive results.
HIV prevention consists of the following points:
- protected sex with non-regular sexual partners, as well as regular ones, if there is no confidence that the partner is not sick or is faithful;
- exclusion from life of drugs and promiscuity;
- maintaining general hygiene. Avoid sharing razors, toothbrushes, nail clippers, and other items that may come into contact with small wounds.
The main prevention is to be aware of the infection and always remember the danger of infection.
Popular questions and answers about HIV
How does HIV manifest in men and women?
The symptoms of HIV in women are exactly the same as the symptoms of HIV in men. Manifestations may differ only at the level of genitourinary diseases, when the body is already very weakened - for example, thrush appears more often in women. Otherwise, there are no specific signs by gender.
Is there a cure for HIV?
Technically, we can say that there is no cure for HIV - patients are constantly required to undergo special therapy. But the results that it allows to achieve make the patient a healthy person who can live calmly for decades without any problems - you just need to constantly take medications and monitor your health.
HIV has not been a fatal disease for a long time!
Is HIV a disease of drug addicts and people with disordered lifestyles?
In fact, this is a myth that HIV activists are constantly dispelling. Unfortunately, a person who leads a healthy lifestyle and is responsible for their relationships can also get this disease. It is enough that a sexual partner can cheat – and in this way “bring” illness to the couple. HIV is not always a sign of an irresponsible attitude towards one’s life.
Who are HIV dissidents?
These are people who, contrary to scientific data and common sense, deny the existence of the virus. They refuse treatment, which inevitably leads to early death. Such people are also dangerous because, due to lack of treatment, they spread the virus among their sexual partners without warning them of the possible danger (because they do not believe that it exists).
The success of HIV treatment and long life lies in seeking help and starting therapy as early as possible. In this case, a person will have a long life without fears and difficulties.
Treatment technology
It is not possible to completely cure HIV. A cure for AIDS has not yet been found, but research in this area continues. The fundamental method of stopping the development of the first symptoms of HIV infection is through medications. They use drugs to treat AIDS, which can blunt the development and support our immunity. This includes drugs for opportunistic diseases and to prevent the development of other viruses and pathologies. Therapy is carried out throughout life.
