HIV 1 Infection
What is HIV 1 Infection?
HIV 1 infection is caused by the human immunodeficiency virus type 1. This virus attacks the immune system, making it harder for your body to fight infections and disease. HIV 1 is the most common type of HIV worldwide and accounts for the majority of cases.
When HIV enters your body, it targets CD4 cells, which are white blood cells that help coordinate your immune response. Over time, the virus destroys these cells and weakens your ability to defend against illness. Without treatment, HIV can progress to AIDS, or acquired immunodeficiency syndrome, which is the most advanced stage of infection.
With modern antiretroviral therapy, people living with HIV can maintain healthy immune systems and live long, active lives. Early detection and consistent treatment can reduce the virus to undetectable levels. This means the virus cannot be transmitted to others and your immune system stays strong.
Symptoms
Many people experience flu-like symptoms within 2 to 4 weeks after HIV infection. This early stage is called acute HIV infection. Common symptoms include:
- Fever and chills
- Fatigue and weakness
- Sore throat
- Swollen lymph nodes
- Muscle aches and joint pain
- Skin rash
- Night sweats
- Mouth ulcers
After this acute phase, many people feel well for years without symptoms. This is called the chronic or clinical latency stage. The virus is still active and can be transmitted to others during this time, even when no symptoms are present.

Causes and risk factors
HIV 1 is transmitted through contact with certain body fluids from an infected person. The virus spreads most commonly through unprotected sexual contact, sharing needles or syringes, and from mother to child during pregnancy, birth, or breastfeeding. Blood transfusions were once a transmission route but are now extremely rare due to screening procedures.
Risk factors include having unprotected sex with multiple partners, having other sexually transmitted infections, using injectable drugs with shared equipment, and having a partner with HIV who is not on effective treatment. Healthcare workers exposed to blood or bodily fluids also face occupational risk. HIV cannot spread through casual contact like hugging, sharing food, or using the same bathroom.
How it's diagnosed
HIV 1 infection is diagnosed through blood tests that detect the virus or antibodies your body makes against it. Antibody tests are the most common and can detect HIV within 3 to 12 weeks after exposure. Antigen and antibody combination tests can find infection sooner, typically 2 to 6 weeks after exposure. Nucleic acid tests like HIV 1 DNA PCR detect the virus itself and are used for early detection, especially in newborns of mothers with HIV.
If you think you may have been exposed to HIV, talk to a doctor about testing options. Early diagnosis allows you to start treatment quickly, which protects your health and prevents transmission. Many clinics offer confidential or anonymous testing. Rite Aid can connect you with healthcare providers who offer specialized HIV testing and care.
Treatment options
Treatment for HIV 1 infection focuses on antiretroviral therapy and lifestyle support:
- Antiretroviral therapy, or ART, which combines multiple medications to suppress the virus
- Daily medication adherence to maintain viral suppression
- Regular monitoring of CD4 count and viral load through blood tests
- Eating a balanced diet rich in fruits, vegetables, lean protein, and whole grains
- Getting regular exercise to support immune function and overall health
- Avoiding smoking and limiting alcohol consumption
- Managing stress through mindfulness, therapy, or support groups
- Preventing other infections through vaccinations and safe practices
- Working closely with an HIV specialist or infectious disease doctor
Frequently asked questions
HIV is the virus that causes infection, while AIDS is the most advanced stage of HIV disease. AIDS is diagnosed when your CD4 count drops below 200 cells per cubic millimeter or when you develop certain serious infections. With early treatment, most people with HIV never develop AIDS.
Detection timing depends on the type of test used. Nucleic acid tests can detect HIV 10 to 33 days after exposure. Antigen and antibody tests work within 18 to 45 days. Standard antibody tests may take 23 to 90 days to show positive results. Testing during the window period may produce false negatives.
No, HIV cannot spread through casual contact like hugging, shaking hands, or sharing utensils. Deep kissing with open sores or bleeding gums carries very low risk. The virus requires direct contact with specific body fluids like blood, semen, vaginal fluids, or breast milk to transmit from person to person.
Yes, sharing your HIV status with healthcare providers is important for your care. This information helps them choose safe medications, monitor for drug interactions, and provide appropriate preventive care. Your medical information is protected by privacy laws. Doctors cannot share your status without your permission except in specific legal situations.
Yes, with proper treatment and care, mothers with HIV can have babies who are not infected. Taking antiretroviral medications during pregnancy reduces transmission risk to less than 1 percent. Additional steps include scheduled cesarean delivery in some cases and avoiding breastfeeding. Babies are tested at birth and monitored closely.
Missing medication doses can allow the virus to multiply and may lead to drug resistance. This makes your current treatment less effective and limits future options. If you miss a dose, take it as soon as you remember unless it's almost time for the next dose. Talk to your doctor about strategies to help you remember daily medications.
The CDC recommends annual testing for most sexually active adults. People at higher risk should test every 3 to 6 months. This includes those with multiple partners, people who share injection equipment, and individuals whose partners have HIV. Regular testing allows for early detection and prompt treatment if needed.
While lifestyle changes cannot cure HIV, they support your immune system and overall health. Eating nutritious foods helps your body respond better to medication. Regular exercise, adequate sleep, and stress management improve quality of life. Avoiding smoking and excessive alcohol protects your liver and cardiovascular system while taking antiretroviral drugs.
Currently, there is no cure that eliminates HIV from the body completely. Antiretroviral therapy suppresses the virus but does not remove it. If treatment stops, the virus returns and begins multiplying again. Researchers are studying potential cures including gene therapy and immune-based approaches, but these remain experimental for now.
