Understanding HIV: The Basics

HIV (Human Immunodeficiency Virus) is a virus that attacks the body’s immune system, specifically targeting CD4 cells (also called T cells). These cells help the immune system fight off infections. When the Human Immunodeficiency Virus damages the immune system, it becomes harder for the body to fight off infections and disease.

Without treatment, HIV infection can lead to Acquired Immunodeficiency Syndrome, the most severe stage of HIV infection. But thanks to modern medicine, most people with HIV in the U.S. don’t develop Acquired Immunodeficiency Syndrome (AIDS) if they take their medication as prescribed.

HIV spreads mainly through:

  • Sexual contact with someone who has Human Immunodeficiency Virus
  • Sharing needles, syringes, or other drug injection equipment
  • From mother to child during pregnancy, birth, or breastfeeding

You can’t get HIV from casual contact like hugging, shaking hands, sharing food, or using the same toilet.

Early HIV Symptoms: The Acute Phase

The initial stage of HIV infection is referred to as the acute infection stage or primary HIV infection. A significant number of individuals, though not all, exhibit flu-like symptoms approximately 2-4 weeks post-virus contraction. This phase is occasionally termed “acute retroviral syndrome” or “primary HIV infection.”

HIV Symptoms

Common Early Symptoms of Acute HIV infection

  • Fever (this is the most common symptom)
  • Chills
  • Night sweats
  • Rash
  • Muscle aches and joint pain
  • Sore throat
  • Swollen lymph nodes, particularly in the neck and groin
  • Mouth ulcers
  • Headache
  • Feeling extremely tired
  • Nausea, vomiting, or diarrhea

Symptoms of acute HIV infection usually last for a few days to a few weeks. Since these symptoms resemble other common illnesses like the flu, they’re often overlooked.

If you’ve recently engaged in behavior that might put you at risk for HIV and experience these symptoms, it’s a good idea to get tested. Even if you don’t have symptoms, getting tested is the only way to know for sure if you have HIV.

Why Early Symptoms Happen

When HIV first enters your body, your immune system tries to fight it off. The body’s battle against the virus causes inflammation, leading to flu-like symptoms. As the virus multiplies rapidly, its high concentration in the bloodstream makes early transmission to others more likely.

The Asymptomatic Stage: When Symptoms Disappear

After the early acute stage, many people enter a phase where they have no symptoms at all. This is called the “chronic HIV infection” or “clinical latency” stage. During this time, the virus is still active but reproduces at very low levels.

The asymptomatic period may extend for several years, sometimes even exceeding a decade, for certain individuals. Others may exhibit mild symptoms or experience periodic infections. Without an HIV test, many people during this stage don’t know they’re infected because they feel perfectly healthy.

Even though you might feel fine during this time, the virus is still causing damage to your immune system. Your CD4 cell count (a measure of immune system health) gradually declines over time. Plus, without treatment, you can still transmit the virus to others during this stage.

This is why regular HIV testing is so important, especially for people with risk factors. The CDC recommends that everyone between the ages of 13 and 64 get tested for HIV at least once as part of routine healthcare, and people with certain risk factors should get tested more often.

Advanced HIV: When Symptoms Return

Without treatment, HIV eventually weakens the immune system to the point where it can’t fight off other infections. In this advanced stage, more severe symptoms manifest. These symptoms typically arise not from HIV directly, but from opportunistic infections and complications that exploit the compromised immune system.

Symptoms of Advanced HIV Infection

  • Rapid weight loss
  • Recurring fever or night sweats
  • Extreme fatigue
  • Swelling of lymph nodes in the armpits, groin, or neck
  • Diarrhea that lasts for more than a week
  • Pneumonia
  • Red, brown, pink, or purplish blotches on or under the skin or inside the mouth, nose, or eyelids
  • Memory loss, depression, and other neurological disorders

Opportunistic Infections

In advanced HIV, the immune system is significantly weakened, leading to infections that are typically harmless in individuals with a healthy immune system becoming potentially life-threatening. These are called opportunistic infections because they take the opportunity of a weakened immune system to cause disease.

Common opportunistic infections in people with advanced HIV include:

  • Pneumocystis pneumonia, a type of pneumonia that’s rare in people with healthy immune systems
  • Candidiasis (thrush), a fungal infection that can affect the mouth, throat, or vagina
  • Toxoplasmosis, an infection that can affect the brain
  • Cytomegalovirus, a viral infection that can affect the eyes, digestive tract, and other organs
  • Tuberculosis, which is more likely to spread beyond the lungs in people with HIV

AIDS-Defining Conditions

When someone with HIV develops certain opportunistic infections or cancers, or when their CD4 count drops below 200 cells/mm³, they’re diagnosed with AIDS. This is the most severe stage of HIV infection.

Some AIDS-defining conditions include:

  • Pneumocystis pneumonia
  • Recurrent pneumonia
  • Kaposi’s sarcoma (a type of cancer)
  • Wasting syndrome (involuntary weight loss of more than 10% of body weight, plus chronic diarrhea or chronic weakness and fever)
  • HIV-associated dementia

With proper treatment, many people with HIV never develop AIDS. Starting treatment early is key to preventing the progression to this advanced stage.

HIV Symptoms in Women vs. Men

HIV symptoms are generally similar in men and women, especially during the early and late stages. However, it is important to note that there are distinctions, particularly as HIV may lead to further complications associated with women’s reproductive health.

Symptoms Specific to Women

Women with HIV may experience:

  • Changes in menstrual cycles, including missed periods or lighter/heavier bleeding
  • More severe vaginal yeast infections that are harder to treat
  • Pelvic inflammatory disease (PID) that’s more difficult to treat
  • Human papillomavirus (HPV) infections that progress faster and may lead to cervical cancer more quickly
  • Higher risk of certain gynecological conditions

Regular gynecological care is particularly important for women living with HIV. This includes more frequent Pap tests to screen for cervical cancer, which is more common in women with HIV.

Symptoms in Transgender Individuals

It’s also important to note that transgender individuals may experience unique health challenges related to HIV. Hormone therapy might interact with some HIV medications, and transgender people often face additional barriers to accessing appropriate healthcare.

Transgender women have higher rates of HIV than the general population, so regular testing and medical care are especially important.

How HIV Testing Works

Getting tested is the only reliable way to know if you have HIV and is the first step to treat HIV. Modern HIV tests are quick, highly accurate, and often free or low-cost. There are several types of tests available:

Types of HIV Tests

  • Antibody tests: These look for antibodies to HIV in your blood or oral fluid. These tests can take 23 to 90 days after infection to detect HIV.
  • Antigen/antibody tests: These tests identify both HIV antibodies and antigens, which are components of the virus itself. They offer quicker detection of HIV compared to antibody-only tests, typically within 18 to 45 days post-infection.
  • Nucleic acid tests (NATs): These look for the actual virus in your blood (HIV RNA). They can detect HIV about 10 to 33 days after infection. These are the most expensive tests and not routinely used for screening unless you had a recent exposure or symptoms of early HIV infection.

Where to Get Tested

You can get tested for HIV at:

  • Your doctor’s office
  • Health clinics or community health centers
  • Sexual health clinics
  • Local health departments
  • Family planning clinics
  • VA medical centers
  • Substance abuse prevention or treatment programs
  • At home with self-testing kits

What to Expect During Testing

HIV testing is quick and simple. Depending on the type of test, either a small sample of blood will be taken from your finger or arm, or an oral swab will be taken from your gums.

Many clinics now offer rapid tests that can give results in as little as 20 minutes. Other tests might require you to wait a few days for results.

All HIV tests in the U.S. are confidential, and many places offer anonymous testing as well. This means your name isn’t linked to your test results.

Living with HIV: Treatment and Management

If you test positive for HIV, there’s good news: you can treat your HIV infection! With proper treatment and care, most people with HIV can live long, healthy lives.

Antiretroviral Therapy (ART)

The main treatment for HIV is called antiretroviral therapy (ART). These medications don’t cure HIV, but they control the virus by stopping it from making copies of itself.

When taken as prescribed, ART can reduce the amount of HIV in your blood (known as the viral load) to very low levels—so low that tests can’t detect it. This is called having an “undetectable viral load,” and it has two major benefits:

  • It helps your immune system recover and stay strong
  • It prevents transmission of HIV to others (this is often called “Undetectable = Untransmittable” or U=U)

ART typically involves taking a combination of HIV medicines daily. Many people now take just one pill once a day.

Living Well with HIV

Beyond medication, there are many things you can do to stay healthy while living with HIV:

  • Regular medical care: See your healthcare provider regularly for check-ups and blood tests to monitor your viral load and CD4 count.
  • Healthy lifestyle: Eating a balanced diet, exercising regularly, getting enough sleep, and avoiding smoking and excessive alcohol can all help you stay healthy.
  • Mental health support: Living with HIV can sometimes be stressful or isolating. Working with a therapist, joining a support group, or connecting with others living with HIV can help with the emotional aspects of managing the condition.
  • Preventing other infections: Get vaccinated against preventable diseases and practice safer sex to avoid other sexually transmitted infections that could complicate your health.

Preventing HIV Transmission

Understanding how to prevent HIV is crucial whether you’re HIV-negative and want to stay that way, or you’re living with HIV and want to protect your partners.

Prevention Strategies for HIV-Negative People

  • Practice safer sex: Use condoms consistently and correctly every time you have sex. Condoms are highly effective at preventing HIV transmission.
  • Pre-exposure prophylaxis (PrEP): This is a medication HIV-negative people can take to prevent getting HIV from sex or injection drug use. When taken as prescribed, PrEP is highly effective.
  • Post-exposure prophylaxis (PEP): If you think you’ve been exposed to HIV in the last 72 hours, contact your healthcare provider about PEP, which can prevent infection after a potential exposure.
  • Get tested regularly: Knowing your status and your partner’s status is an important prevention strategy.
  • Never share needles: If you inject drugs, always use new, sterile needles and equipment.

Prevention Strategies for People Living with HIV

  • Take your medication as prescribed: Maintaining an undetectable viral load means you can’t transmit HIV to sexual partners.
  • Inform your partners: Honest communication about your HIV status allows your partners to make informed decisions about prevention strategies.
  • Practice safer sex: Even with an undetectable viral load, using condoms can protect against other sexually transmitted infections.

HIV Stigma and Getting Support

Despite significant medical advancements, HIV-related stigma continues to be prevalent and can impede access to testing, treatment, and support services. Stigma encompasses negative attitudes and beliefs towards individuals living with HIV and may result in discrimination, wherein people are treated differently based on their HIV status.

Dealing with Stigma

  • Know the facts: Educating yourself and others about how HIV is and isn’t transmitted can help reduce fear and stigma.
  • Find supportive healthcare: Work with healthcare providers who are knowledgeable about HIV and treat you with respect.
  • Connect with others: Support groups for people living with HIV can provide understanding from others who share similar experiences.
  • Know your rights: In the U.S., people living with HIV are protected from discrimination under the Americans with Disabilities Act.

Resources for Support

Many organizations provide support, information, and services for people affected by HIV:

  • CDC HIV/AIDS Information: 1-800-CDC-INFO (1-800-232-4636)
  • HIV.gov: Information on HIV basics, testing, and local services

When to See a Doctor

If you have any reason to believe you might have been exposed to HIV—whether through unprotected sex, sharing needles, or other risk factors—you should get tested, even if you don’t have symptoms.

You should also see a doctor if you experience:

  • Persistent, unexplained symptoms like fever, fatigue, swollen lymph nodes, or night sweats
  • Symptoms of sexually transmitted infections, which can increase your risk of HIV transmission
  • Any of the advanced symptoms mentioned earlier, especially if you haven’t been tested recently

Remember: early diagnosis and treatment lead to the best outcomes, so don’t delay seeking medical attention if you’re concerned.

FAQs

Can you have HIV without any symptoms?

Yes, absolutely. Many people with HIV don’t have any symptoms for years after infection. During this asymptomatic period, the virus is still active in the body and can be transmitted to others. This is why regular testing is so important, especially if you have risk factors for HIV.

How soon after exposure do symptoms appear?

If symptoms do appear, they usually show up within 2-4 weeks after infection. These early symptoms often resemble the flu and typically last for a few days to a few weeks. However, not everyone experiences these early symptoms, and some people remain symptom-free for many years.

What’s the difference between HIV and AIDS?

HIV is the virus that causes the condition. AIDS is the most advanced stage of HIV infection, diagnosed when a person’s immune system is severely damaged and they develop certain opportunistic infections or cancers, or when their CD4 count drops below 200 cells/mm³. With modern treatments, many people with HIV never develop AIDS.

Can HIV symptoms come and go?

Yes, symptoms can fluctuate, especially during the early stages of infection. Someone might feel sick for a few days, then feel better for a while, then develop different symptoms. This inconsistency is one reason why symptoms alone aren’t reliable for diagnosing HIV.

If I tested negative for HIV, could I still have it?

It depends on when you were tested and what kind of HIV test you underwent. Most HIV tests look for antibodies your body makes in response to the virus. It can take time for these antibodies to develop—up to 3 months in some cases. This period is called the “window period.” If you’re tested during this window period, you might get a false-negative result. If you’re concerned about a recent exposure, talk to your healthcare provider about when to get retested.

Can HIV be cured?

Currently, there’s no cure for HIV. However, with proper medical care and antiretroviral treatment, HIV can be controlled. People with HIV who receive proper treatment can live long, healthy lives and have effectively no risk of transmitting the virus to their HIV-negative sexual partners.

Can I get HIV from kissing someone who has it?

HIV isn’t transmitted through casual contact like closed-mouth kissing, hugging, sharing food, or using the same toilet. There’s a theoretical risk of transmission through open-mouth kissing if both people have bleeding gums or sores, but this is extremely rare and not documented as a common way that HIV is spread.

Summary

Understanding symptoms is an important step in protecting your health and the health of others. Remember that symptoms aren’t a reliable way to tell if you have HIV—the only way to know for sure is to get tested.

If you do test positive for HIV, know that with today’s HIV treatment, people with HIV can live long, healthy lives. Early diagnosis and treatment are key to staying healthy and preventing transmission to others.

Whether you’re concerned about your own risk, looking for information to support someone else, or just want to be better informed, I hope this guide has given you the knowledge you need. Remember that HIV care and prevention have come a long way, and support is available every step of the way.
