How is HIV transmitted?

Mondo Health Updated on 2024-03-02

Xiao Li, male, 33 years old, is usually in good health and rarely gets sick. Half a month ago, he suddenly appeared in many places on his bodyRed rash, densely distributedArms, chest and back。At first, he thought it was just an ordinary ** allergy or heat rash, and thought that as long as he waited a few days, the rash would subside naturally. But as time passed, these red rashes did not disappear as he wished, insteadMore and more, and even start to itch, making him unbearable.

Not only that, but in the past week, Xiao Li also initiatedLow-grade fever, the body temperature persists37.8 or so, although he tried all sortsAntipyretics, but none of them have a significant effect

The double trouble of red rash and low-grade fever made Xiao Li finally decide to go to the hospital for help and seek help from a professional doctor.

The doctor inquired about Xiao Li's medical history and symptoms in detail, and then arranged a series of tests, including blood routine, liver and kidney function tests.

In the process of waiting for the result, Xiao Li's heart was full of apprehension and uneasiness.

After a long wait, the results are finally out. The doctor took the test report and told Xiao Li with a serious expression that his blood was inPositive for HIV antibodies, which means that he has AIDS. Hearing this news, Xiao Li was like five thunderbolts, and his heart was full of fear and despair.

The doctor patiently explained to Xiao Li that AIDS is the main thingAttacks the body's immune system, resulting in a decrease in immunity, susceptibility to various diseases, Xiao Li's rash and low-grade fever are all causesWeakened immunitySymptoms. Although AIDS cannot be AIDS, it can effectively control the disease and prolong life through timely medication and reasonable life adjustment.

The doctor then told Li that the rash and low-grade fever on his body were among the common symptoms in the early days of AIDS.

As the immune system is attacked by the virus, the body is unable to effectively resist the invasion of external pathogens, which triggers a range of symptoms. And now, the key is to start accepting it right awayAnti-HIV drugs**to slow the progression of the disease.

On the advice of the doctor, Xiao Li began to receive the system's **. He regularly goes to the hospital to pick up his medication and takes it strictly according to the doctor's instructions. At the same time, he began to pay attentionAdjust your lifestyleMaintain a good routine, exercise and improve immunity.

Xiao Li's experience tells us that although the initial symptoms of AIDS are very similar to the first disease, it is actually a dysfunction of the immune system, which can lead to the appearance of AIDS over timeSevere infectionand so on, and even life-threatening. If we only treat these **abnormalities as ordinary diseases, it will delay the real disease**, let's take a look at it togetherHow is AIDS transmitted?

AIDS is an infectious disease caused by the HIV virus. When the virus enters the human body,Invasion of human T lymphocytes, so that the immune system gradually collapses, so that the probability of opportunistic infection and tumorigenesis increases significantly. There are three main ways in which AIDS is transmitted, namely:Sexually transmitted, blood-borne and mother-to-child transmission.

Sexual transmissionIt is one of the routes of transmission, especially between men and women or between men and women who have unprotected sex that is most likely to lead to the transmission of AIDS. Therefore, when describing the risk of transmission, protective measures such as avoiding unprotected sex and using condoms correctly should be emphasized.

Blood-borneIt is also an important route of transmission. Blood-borne transmission can passShare syringes, drug use, transfusion of HIV-contaminated blood or blood products, etc. Therefore, emphasis should be placed on avoiding these behaviors, as well as ensuring blood safety in medical practices.

Mother-to-child transmissionrefers to the transmission of the virus from mother to child during pregnancy, childbirth or breastfeeding, so emphasis should be placed on HIV screening and intervention for pregnant women. The higher the HIV load, the greater the risk of transmission. Therefore, if an AIDS patient wants to conceive the next generation, he must use drugsThe self-virus load is controlled in a very low range

With the deepening of medical research, antiretroviral drugs have become increasingly important in HIV**.

At present, there are many kindsAntiviral drugsCame out, asProtease inhibitors, reverse transcriptase inhibitorsetc., these drugs can effectively inhibit viral replication.

After infectionWithin 72 hoursThe key is to take it as soon as possibleAntiviral drugs to block it。The purpose of this self-help measure is to stop the virus from entering the body's cells and replicating. Commonly used combinations of blocking drugs include:Tenofovir + emtricitabine + raltegravir(or other integrase inhibitors). These medications need to be taken as soon as possible after infection, preferably within 2 hours, but even after 2 hours, starting within 48 hours** may still be effective. Blockade** needs to be continued for 28 days, during which time the drug cannot be discontinued or missed to ensure successful blockade.

It is important to note that blocking ** does not completely guarantee success, because:Viral load after infectionand individual differences may affect the effect. In addition, blocking HIV does not, only controls viral replication and slows the progression of the disease.

In addition to ** short-term infections using antiviral blocking drugs,Immunomodulation**It is also a common means of HIV**. Immune boostersSuch as:il-2It can enhance immune function and the body's defenses. These drugs are often used as an adjunct to improve the effectiveness of antivirals.

It may be necessary in certain situations, such as when autoimmune diseases or immune overactivationImmunosuppressantsto control the immune response. However, this should be used with caution to avoid triggering opportunistic infections or other adverse effects.

VaccinesIt is an important means of preventing the spread of AIDS. Scientists are actively researching HIV vaccines in the hope of preventing the onset of AIDS through vaccination.

How do we know that we have HIV in the early stages of AIDS, which is often undetectable? After being infected with HIV, if you have any of the following conditions, you must go to the hospital as soon as possible.

*As the largest organ of the human body, it not only has the functions of protection, regulating body temperature, sensation and so onIt is also a window for the outward manifestations of many diseases。Therefore, when there is an abnormality, we should go to the hospital for examination in time for early detection and early detection. Below, we will go in detail about the three conditions that need to be checked by the hospital as soon as possible, as well as the medical principles and treatment methods of these conditions.

1. Erythema with prolonged fever

The principle of the rash caused by AIDS** is related to the effects of HIV on the immune system.

When the human immunodeficiency virus (HIV) infects the body, it destroys the immune system, especially the effectsCD4+ T cellsThese cells are an important part of the immune system.

With the decrease in the number of CD4+ T cells, it leads:The body struggles to fight off various pathogens, including those pathogens that cause the problem. In addition, HIV itself may also have a direct effect on **cells, leading to ** lesions.

These lesions may manifest:Red rash, papules, itching, drynessand other symptoms.

These problems may be due to direct damage to cells by viruses or due to a weakened immune system that makes it more susceptible to infections from other pathogens such as bacteria, fungi, etc.

* A rash or rash on the surface may beTransient allergiesIt can subside in a short time. ButPersistent fever with **abnormality, seek medical attention as soon as possible.

2. ** There is damage and the damage area is very large

* It is the first line of defense of the body, which can prevent external bacteria, viruses and other pathogens from entering the body.

When the damaged area is too large, this line of defense is weakened and pathogens are more likely to invade, increasing the risk of infection. If left untreated, the infection can spread further and even lead to serious complications.

*If the damaged area is too large, it will be more difficult to heal on its own.

Wound healing requires adequate nutrients and oxygen**, while extensive damage can lead to poor local blood circulation and affect the healing process.

3. Shingles appears on **

Herpes zoster is a type of blister that spreads along the nerves and forms bands.

In the early stages of shingles, patients may develop flushing spots, which will appear quicklyMiliary to soybean-sized pimples

Subsequently, these papules quickly turn into blisters that fuse together and are distinctNeuralgia

There is a correlation between AIDS and shingles. Herpes zoster is caused byVaricella-zoster virusThe virus usually manifests as chickenpox when first infected, after which the virus remains latent in the body.

When the immune system is weakened, the immune function is impaired due to HIV infectionLatent viruses may be reactivated, triggering shingles.

Herpes zoster may be more severe in people with AIDS. Typical symptoms include the bodyPainful blisters on one sideThese blisters usually follow the nerves and form bands. In addition to the symptoms, shingles may also be accompanied by symptoms such as fever, headache, general malaise, and swollen lymph nodes.

Because people with AIDS are immunocompromised, shingles may be more likely to develop and symptoms may be more severe. Therefore, AIDS patients should seek medical attention in time when they develop symptoms of herpes zoster and receive targeted treatment**.

At the same time, keepGood immune function and **cleanto help prevent the occurrence of shingles.

In fact, AIDS is not a simple ** disease, those abnormalities that appear on ** are warning signals from the body, and we should pay enough attention to it. When**Abnormal with prolonged fever, Presence of a breakage with a large area of breakage, Appearance of shinglesIn other cases, you should go to the hospital for examination as soon as possible for early detection and early detection.

We also need to pay attention to HIV/AIDS prevention, strengthen publicity and education, raise people's awareness of self-protection, and reduce the risk of HIV/AIDS transmission.
