What is hiv?
HIV (Human Immunodeficiency Virus) is a virus that attacks the immune system, making it difficult for the body to fight off infections and certain cancers. If left untreated, HIV can lead to AIDS (Acquired Immunodeficiency Syndrome), which is a collection of symptoms and infections that occur as a result of a severely damaged immune system. HIV is primarily spread through sexual contact, sharing of needles and other injection equipment, and from mother to child during pregnancy, childbirth, and breastfeeding.
What causes hiv?
HIV is caused by the human immunodeficiency virus. It attacks the immune system by destroying CD4 cells (T cells), which are crucial to fighting off infections. HIV is primarily transmitted through sexual contact with an infected person, sharing of needles or other injection equipment with an infected person, or from a mother to her child during pregnancy, childbirth, or breastfeeding. The virus can enter the body through cuts or sores on the skin, or through the lining of the vagina, rectum, mouth, or eyes. Once inside the body, HIV multiplies and spreads, gradually damaging the immune system over time.
What happens if I get hiv?
If you are infected with HIV, the virus will gradually damage your immune system over time. In the early stages of HIV infection, you may experience flu-like symptoms such as fever, fatigue, muscle aches, and sore throat. However, some people may not experience any symptoms for several years.
Without treatment, the virus will continue to multiply and eventually cause a decline in the number of CD4 cells (T cells) in your body. This can lead to a weakened immune system and make you more susceptible to infections and certain cancers.
If the damage to your immune system is severe enough, you may eventually develop AIDS (Acquired Immunodeficiency Syndrome). This is the most advanced stage of HIV infection and is defined by a decline in the number of CD4 cells and the occurrence of certain infections and cancers.
It is important to get tested for HIV if you think you may have been exposed to the virus and to seek prompt medical care if you test positive. With proper medical care, it is possible to manage HIV and slow the progression of the disease
What are the main symptoms of HIV?
In the early stages of HIV infection, some people may experience flu-like symptoms such as:
Fever
Fatigue
Muscle aches
Sore throat
Headache
Rash
However, many people may not experience any symptoms at all during this stage, and the only way to know for sure if you have been infected with HIV is to get tested.
As the virus progresses and damages the immune system, you may experience symptoms such as:
Persistent fatigue
Swollen lymph nodes
Yeast infections (thrush) in the mouth or throat
Persistent headaches
Weight loss
Diarrhea
If the virus is not treated, you may eventually develop AIDS (Acquired Immunodeficiency Syndrome), the most advanced stage of HIV infection. At this stage, you may experience symptoms such as:
Serious and recurring infections
Kaposi sarcoma (a type of skin cancer)
Pneumocystis pneumonia (a severe lung infection)
Toxoplasmosis (a brain infection)
Cryptococcal meningitis (a brain and spinal cord infection)
It is important to seek medical care as soon as possible if you think you may have been infected with HIV. Your healthcare provider can advise you on the best course of treatment.
How to Testing hiv?
There are several methods for testing for HIV, including:
Blood tests: Blood tests are the most common method for testing for HIV. These tests look for antibodies (proteins produced by the immune system in response to the virus) to the virus or for the virus itself in the blood. Blood tests can detect HIV infection within 2 to 4 weeks after exposure.
Saliva tests: Saliva tests work by detecting antibodies to the virus in saliva. These tests are less commonly used than blood tests, but they are easy to use and do not require a blood sample.
Urine tests: Urine tests for HIV detect antibodies to the virus in urine. These tests are less commonly used than blood tests, but they are easy to use and non-invasive.
Rapid Tests: Rapid tests can provide results in about 20 minutes using a small sample of blood from a finger prick or oral fluid.
It is important to get tested as soon as possible if you think you may have been exposed to HIV. Early diagnosis and treatment can help slow the progression of the disease and improve health outcomes. Your healthcare provider can advise you on the best testing method for your needs and provide you with information on where to get tested
