HIV, its connection with AIDS and effects on immune system
HIV, its connection with AIDS and effects on immune system Human immunodeficiency virus (HIV) is a type of virus which damages your immune system. Your immune system is a basic system in body that fights off infections. HIV must be treated, if it is left untreated it infects in your body. There is a special type of immune cells called T cells and also CD4cells. HIV virus kills these CD4 cells. Without CD4 cells, your body couldn’t able to fight different kinds of infections and cancers causing viruses. This type of virus doesn’t spread through the water, air and food. People can get this by casual contact.
Many of the scientists are working to find the cure of HIV, but still there is no cure for HIV. It is also known as lifelong condition. However, there are always some of the medical treatments available here. By some of the treatments it can be managed such as by medical care and antiretroviral therapy.
As treatments are available so person with this disease should get treated to live life. Without treatment, the person with HIV can get more serious diseases such as AIDS. HIV makes the immune system weaker and unable it to fight against other diseases as well. With AIDS about three years of life expectancy have observed without treatment. HIV treated with antiretroviral therapy, whether it is well-controlled but life expectancy chances are same as the person who has not contracted HIV.
Many of the people with this virus are not aware with this disease. Americans have estimated that 1.1 million people are currently living with HIV.
How HIV can be transmitted?
It cannot be transmitted by air, water or food. It can be transmit by casual contact which may have some of these bodily fluids:
- Vaginal and rectal fluids
- Breast milk
HIV and AIDS:
HIV and AIDS are related to each other but they both are not same things. A person to develop AIDS must have contracted HIV. It is not necessary that a person with HIV must have AIDS. There are some of the stages of HIV progress.
- Stage 1: the first few weeks after transmission are called acute stage.
- Stage 2: it is clinical latency or chronic stage.
- Stage 3: its last stage and having AIDS.
The final stage of HIV is Acquired immunodeficiency syndrome (AIDS). At the stage of AIDS, your immune system severely affected. With the severity of AIDS, people get greater chances of getting contracting infections.
However, all the people with HIV will not get develop AIDS. It’s good to diagnose it on time, so you can get better outcome.
CD4 count for an adult person is about 500 to 1,500 per cubic millimeter. The person with CDS count below 200 is supposed to have AIDS. The stages also vary of getting progression of HIV through the chronic stage varies.
What are the effects of HIV on immune system?
We know about HIV but most of us don’t know how it affects your body. It basically destroys the CD4 cells which help us to keep healthy ourselves and stay away from various diseases. It disturbs our immune system as well. HIV causes signs of weakens. We have no idea what happens in our body when it enters in body.
When human immunodeficiency virus (HIV) enters in your body, it directly affects your immune system. Progresses of HIV vary in different ages and on your health. It is very important to diagnose it on time, if you don’t diagnose it so the treatments become more difficult.
Then HIV targets the different types of cells which fight off diseases. As we know, virus replicates itself so it produces more viruses and causes more damages of fight off cells. This cycle of continuation, continue throughout the life until it’s not diagnosed or treated. It causes your immune system weaker with the passage of time and making the progress of risks for serious diseases and infections.
Some of the HIV effects on your body are given here.
Your immune system is a role model system that acquires the diseases and infections come over your way. White blood cells defend you against viruses, bacteria, and all other organisms that cause sickness.
Their symptoms can be mild at the early stages. Later on, after few months the symptoms can become severe. You may also experience a flu-like sickness for some of weeks. This type of symptom is associated with the first stage of HIV such as acute infection stage.HIV, its connection with AIDS and effects on immune system This type of HIV may not have serious symptoms but the virus reproduces rapidly in your blood.
The symptoms of acute can include:
- Sore throat
- Joint pain
- Night sweats
- Muscle aches
- Swollen lymph glands
- Mouth or genital ulcers
After this stage the next stage is called clinical latent infection state. During this stage you may not suffer with the symptoms. It can last for much longer time or may 8 to 10 years.
With the progress of this virus and rapid reproduction of it can cause decrease in number of CD4+ cells. This type can lead some of these symptoms such as:
- Shortness of breath
- Swollen lymph nodes
- Weight loss
As time passes with this disease, puts you at an increased risk of many of diseases. This can include herpes virus called cytomegalovirus. It can affect and cause problems with your eyes, lungs, and digestive tract.
Another type of possible infection is a blood vessel wall of the blood. It is known as Kaposi sarcoma. This type of disease is rare among the general population but its common in those people who are HIV positive. Symptoms of this kind are included red or dark purple lesions on the mouth or skin. It can cause serious problems in the lungs, digestive tract and other internal infections.
HIV and AIDS increases the higher risks of developing lymphomas. The early signs of it are swollen lymph nodes.
