Symptoms
Common signs and symptoms of HIV/AIDS include:
When to see a doctor
If you experience severe or worsening symptoms, seek immediate medical attention. Always consult with a healthcare professional for proper diagnosis and treatment.
Causes & Risk Factors
Several factors can contribute to HIV/AIDS.
HIV spreads through contact with certain body fluids from an infected person, including blood, semen, vaginal fluids, rectal fluids, and breast milk.
HIV spreads through contact with certain body fluids from an infected person, including blood, semen, vaginal fluids, rectal fluids, and breast milk. Think of HIV as a virus that needs a direct highway into your bloodstream - it can't survive long outside the human body and doesn't spread through casual contact like hugging, sharing utensils, or breathing the same air.
The most common ways HIV transmits include unprotected sexual contact (anal, vaginal, or oral sex), sharing needles or syringes for drug use, and from mother to child during pregnancy, childbirth, or breastfeeding.
The most common ways HIV transmits include unprotected sexual contact (anal, vaginal, or oral sex), sharing needles or syringes for drug use, and from mother to child during pregnancy, childbirth, or breastfeeding. Healthcare workers can also be exposed through accidental needle sticks, though this is rare with proper safety protocols.
Contrary to early misconceptions, HIV doesn't spread through saliva, sweat, tears, or casual contact.
Contrary to early misconceptions, HIV doesn't spread through saliva, sweat, tears, or casual contact. You can't get HIV from toilet seats, doorknobs, sharing food, or being around someone who's coughing or sneezing. The virus is actually quite fragile outside the human body and dies quickly when exposed to air.
Risk Factors
- Having unprotected anal or vaginal sex
- Having multiple sexual partners
- Having another sexually transmitted infection
- Sharing needles, syringes, or drug equipment
- Receiving unsafe blood transfusions or organ transplants
- Being born to a mother with untreated HIV
- Having sexual partners who inject drugs
- Engaging in sex work without consistent protection
- Being a healthcare worker with potential blood exposure
- Having sexual contact while under influence of alcohol or drugs
Diagnosis
How healthcare professionals diagnose HIV/AIDS:
- 1
If you're concerned about HIV exposure, the first step is getting tested.
If you're concerned about HIV exposure, the first step is getting tested. Modern HIV tests are highly accurate and much simpler than many people expect. Your healthcare provider will likely start with a conversation about your risk factors and any symptoms you've noticed, though many people with HIV feel perfectly fine when first diagnosed.

Most HIV testing today uses a combination test that looks for both HIV antibodies (proteins your body makes in response to the virus) and antigens (parts of the virus itself).
Most HIV testing today uses a combination test that looks for both HIV antibodies (proteins your body makes in response to the virus) and antigens (parts of the virus itself). This can be done with a simple blood draw or even a finger prick. Rapid tests can provide results in 20 minutes, while standard lab tests typically take a few days. Some people prefer at-home testing kits, which are FDA-approved and highly reliable when used correctly.

If your initial test is positive, your doctor will order additional tests to confirm the diagnosis and assess your immune system.
If your initial test is positive, your doctor will order additional tests to confirm the diagnosis and assess your immune system. These include a CD4 count (measuring your immune cells) and a viral load test (measuring how much virus is in your blood). These numbers help determine how advanced the infection is and guide treatment decisions. Your doctor will also test for other sexually transmitted infections and assess your overall health.
Complications
- Without treatment, HIV progressively weakens your immune system, making you vulnerable to opportunistic infections and certain cancers that healthy immune systems typically prevent.
- AIDS is diagnosed when your CD4 count drops below 200 cells per microliter or when you develop specific AIDS-defining conditions like pneumocystis pneumonia, certain lymphomas, or severe brain infections.
- Even with successful treatment, people with HIV face slightly higher risks of certain health conditions, including heart disease, kidney problems, bone loss, and some cancers.
- However, many of these risks can be managed with regular medical care, healthy lifestyle choices, and preventive treatments.
- The key is maintaining consistent HIV care and addressing other health factors like smoking, diet, and exercise that affect everyone's long-term health.
Prevention
- Getting tested regularly and knowing your partner's status
- Treating other sexually transmitted infections promptly
- Limiting number of sexual partners
- Avoiding sharing personal items that might have blood on them
- Choosing licensed facilities for tattoos, piercings, or medical procedures
- For people who inject drugs, using clean needles and accessing needle exchange programs
The cornerstone of HIV treatment is antiretroviral therapy (ART), a combination of medications that work together to suppress the virus and protect your immune system.
The cornerstone of HIV treatment is antiretroviral therapy (ART), a combination of medications that work together to suppress the virus and protect your immune system. Modern ART regimens are typically just one or two pills taken daily, a far cry from the dozens of pills people needed in earlier decades. These medications don't cure HIV, but they can reduce the virus to undetectable levels in your blood.
Most people start with a combination that includes drugs from different classes: integrase inhibitors, reverse transcriptase inhibitors, and sometimes protease inhibitors.
Most people start with a combination that includes drugs from different classes: integrase inhibitors, reverse transcriptase inhibitors, and sometimes protease inhibitors. Popular first-line options include combinations like tenofovir/emtricitabine/bictegravir or dolutegravir-based regimens. Your doctor will choose based on your specific situation, other health conditions, and potential drug interactions.
The goal of treatment is achieving an undetectable viral load, typically within three to six months of starting therapy.
The goal of treatment is achieving an undetectable viral load, typically within three to six months of starting therapy. When your viral load is undetectable, you cannot sexually transmit HIV to partners - a concept known as "undetectable equals untransmittable" or U=U. This has been one of the most encouraging developments in HIV care, allowing people to have normal intimate relationships without fear of transmission.
Regular monitoring is essential for successful treatment.
Regular monitoring is essential for successful treatment. You'll typically see your HIV specialist every three to six months for blood work checking your viral load, CD4 count, and overall health. Side effects from modern HIV medications are generally mild, but your doctor will watch for any issues and can adjust your regimen if needed. Research continues to advance, with long-acting injectable medications now available for some people who prefer alternatives to daily pills.
Living With HIV/AIDS
Living well with HIV today means taking your medications consistently, maintaining regular medical care, and focusing on overall health and wellness. Most people with well-controlled HIV lead completely normal lives - working, traveling, having relationships, and raising families. The daily routine typically involves taking one or two pills, much like people manage other chronic conditions like diabetes or high blood pressure.
