HIV/AIDS: Symptoms, Causes, Stages, Treatment & Prevention
HIV (Human Immunodeficiency Virus) is the virus that attacks the immune system, while AIDS (Acquired Immunodeficiency Syndrome) is the most advanced stage of HIV infection. At Mahatma Gandhi Hospital (MGH), Jaipur, the Department of Infectious Diseases provides care for infectious conditions, including HIV medicine, supported by diagnostic services and confidential counselling. This guide explains the symptoms, stages, transmission, testing, treatment, and prevention of HIV, helping you understand when to seek medical advice and appropriate care.
What is HIV?
HIV's full form is Human Immunodeficiency Virus. A virus that attacks the CD4 cells, a specific type of white blood cell playing an important role in the body's immune response. After entering the body, HIV slowly reduces the body's ability to protect itself from infections and some cancers. If left untreated, this can persist over the years, making the body more susceptible to diseases it might otherwise be able to ward off.
What is AIDS?
Acquired Immunodeficiency Syndrome is the meaning of AIDS. It is the most severe form of HIV infection, occurring when the immune system is so impaired that opportunistic infections and some types of cancer occur. While not all people with HIV will develop AIDS, particularly with early diagnosis and treatment, it is a real and serious possibility that someone with HIV will progress to AIDS if nothing is done.
HIV and AIDS - What's the difference?
HIV is the virus; AIDS is a syndrome, a group of symptoms and infections that may develop as a result of chronic and untreated HIV infection. Someone with HIV may be able to live for years without showing any symptoms and while being treated to keep the virus under control and the immune system strong. AIDS is diagnosed, however, only when there is a decrease in CD4 cell count below a critical level or the presence of certain opportunistic infections. Simply put, all AIDS cases are HIV cases, but not all HIV cases are AIDS cases.
Causes of HIV/AIDS: How Does Transmission Happen?
HIV is transmitted by certain body fluids such as blood, semen, vaginal fluids, and breast milk. The most common ways to contract HIV/AIDS are:
-
Not using an effective or correct condom during sexual intercourse with an infected person.
-
Sharing needles or syringes when taking drugs.
-
Transmission from mother to child during pregnancy, delivery, or lactation.
-
Blood transfusion with contaminated blood or blood products (rare with modern screening)
-
Accidental needlestick injuries can expose healthcare workers to HIV-infected blood and are a recognized occupational risk.
HIV is also associated with other sexually transmitted infections (STIs), which can make the person more likely to be infected with HIV when he or she has sexual contact with someone who is infected.
Can HIV Be Transmitted Through Casual Contact?
Hugging, shaking hands, sharing food or drinks, using the same toilet, or being in the same room as someone with HIV does not spread HIV. The virus is not very infectious outside the body and can only be transmitted via direct contact with body fluids.
Can HIV Spread Through Kissing?
Casual kissing with closed lips is almost risk-free. A theoretical, but extremely small risk, is the kissing of open sores or bleeding gums on both sides because the concentration of saliva is not enough to transmit HIV.
HIV Symptoms: What to Watch For
The symptoms of HIV differ in each stage and may not be noticeable initially. Because HIV may cause few or no noticeable symptoms, testing is important when someone may have been exposed to the virus or has other risk factors.
When Do HIV Symptoms Appear?
Within two to four weeks of exposure, symptoms usually occur at a time referred to as the acute infection stage. This is sometimes referred to as asking, “How long does it take for someone to get symptoms of HIV?” but the answer may differ for each person.
What is Usually the First Sign of HIV?
The first sign of HIV (also known as acute retroviral syndrome) is typically a flu-like illness. It can include:
-
Fever and chills
-
Sore throat
-
Swollen lymph nodes
-
Fatigue
-
Muscle aches
-
Skin rash
-
Night sweats
These are the early-stage HIV symptoms—often confused with a common viral illness, hence the importance of more than just symptoms.
HIV Symptoms in Men
Early HIV symptoms in men can be similar to those in other adults, including fever, sore throat, swollen lymph nodes, fatigue, muscle aches, and rash. Some people may have no symptoms at all.
HIV Symptoms in Women
As a woman's immune system weakens due to HIV, so do the symptoms of the disease; women may experience additional yeast infections of the vagina, pelvic inflammatory disease, and irregular periods.
Early Stage HIV Tongue Symptoms
Oral thrush can cause white or creamy patches in the mouth. Although it can occur in people with HIV, it has several possible causes and does not by itself indicate HIV infection. A healthcare professional should evaluate persistent or unexplained oral thrush.
The 3 Stages of HIV Infection
Knowing the three stages of HIV infection can help to make sense of the course of untreated HIV:
-
Acute HIV Infection: happens within two to four weeks after being exposed; symptoms resemble a flu infection; viral load increases rapidly; and viral replication is rapid.
-
Chronic HIV Infection (Clinical Latency): When the virus continues to multiply in your body in small amounts, and you may not experience any symptoms. This phase may take 10 years or more, particularly if viral load is controlled with antiretroviral therapy.
-
AIDS (Stage 3): When the CD4 cell count drops below 200 cells/mm³, or certain opportunistic infections occur.
HIV Last-Stage Symptoms
The symptoms of the final stage of HIV (AIDS) include continued fever, swelling of the lymph nodes, prolonged diarrhea, repeated infections that the immune system can no longer fend off, constant fatigue, skin lesions, and rapid weight loss. If left untreated, this phase is very dangerous and life-threatening.
HIV Screening and Diagnosis
What is the Window Period for HIV Testing?
The window period is the time between HIV exposure and when a particular test can reliably detect infection. The length varies depending on the test used. If testing is done soon after a possible exposure, a healthcare professional may recommend repeat testing after the appropriate window period.
What Tests Are Used to Diagnose HIV?
An antibody test: Tells if the body has produced antibodies against HIV.
Antigen/antibody tests: Identify both the virus p24 antigen and antibodies, which may be used to detect the virus earlier.
Nucleic acid tests (NAT): Check for the presence of the virus itself and may detect infection earliest; generally used when recent high-risk exposures are suspected.
The best way to begin HIV treatment is to be diagnosed early, which is why HIV screening is so important and can help prevent further immune system damage.
How Is HIV Treated?
HIV is not curable, but antiretroviral therapy (ART) has changed it from a fatal disease to one that can be managed and treated as a chronic condition. ART reduces viral load, sometimes to undetectable levels, which enables the immune system to regain its strength and be more effective. Frequent tests of the CD4 count and viral load allow doctors to adjust treatment and identify potential problems early.
Comprehensive HIV care and management include the management of opportunistic infections as well as the management of co-existing STIs and mental health problems.
Prevention of HIV/AIDS: 5 Ways to Reduce Risk
Consistent and practical measures are the key to HIV/AIDS prevention:
-
Have safe sex: Use condoms properly, always.
-
Don't share needles: Do not share needles, syringes, or other injection equipment.
-
Get tested regularly: If you have multiple sexual partners or other risk factors, regular HIV testing can detect HIV early.
-
Talk about PrEP (HIV pre-exposure prophylaxis): PrEP medication can substantially lower the risk of HIV infection for people who are at high risk.
-
Treat other STIs promptly: Addressing other STIs reduces vulnerability to HIV spread.
Reducing HIV transmission relies on open communication with partners, disclosure of HIV status if applicable, and consistent use of prevention tools—it's about using multiple tools, not just one.
