What Are the Signs of HIV?

Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system, specifically the CD4 cells (T cells), which help fight infections. If untreated, HIV can lead to Acquired Immunodeficiency Syndrome (AIDS). Understanding the early and late signs of HIV is crucial for early diagnosis and treatment.

Early Signs of HIV Infection

The first stage of HIV, known as acute HIV infection, usually appears within 2 to 4 weeks after exposure. Some people develop flu-like symptoms, while others may not notice any signs at all. According to the Centers for Disease Control and Prevention (CDC), early symptoms may include:

Fever and chills
Swollen lymph nodes
Rash on the body
Sore throat
Night sweats
Fatigue and body aches
Mouth ulcers

These symptoms can be mistaken for other viral illnesses, which is why testing is the only reliable way to confirm HIV.

Latent Stage of HIV

After the initial phase, HIV often enters a clinical latency stage, also called chronic HIV. During this period, the virus is still active but reproduces at very low levels. People may not experience noticeable symptoms for years, but the virus continues to damage the immune system.

Advanced Signs of HIV (AIDS)

If untreated, HIV progresses to AIDS, the most severe stage of infection. The immune system becomes extremely weak, making the body vulnerable to opportunistic infections and certain cancers. The World Health Organization (WHO) notes that common advanced symptoms include:

Rapid weight loss
Persistent fever or night sweats
Prolonged swelling of lymph nodes in the neck, armpits, or groin
Chronic diarrhea
Sores on the mouth, anus, or genitals
Pneumonia and frequent infections
Red, brown, or purple skin blotches (Kaposi’s sarcoma)
Memory loss, depression, or neurological disorders

Importance of HIV Testing

Because HIV symptoms can be mild or absent for years, testing is the only way to know for sure. Modern HIV tests are highly accurate, and early detection allows for effective treatment with antiretroviral therapy (ART). ART helps people with HIV live long and healthy lives and prevents transmission to others.

When to See a Doctor

If you think you may have been exposed to HIV, it’s important to seek medical attention immediately. Post-exposure prophylaxis (PEP), if started within 72 hours, can help prevent infection. Regular testing is recommended for people at risk, including those with multiple sexual partners or who share needles.

Conclusion

The signs of HIV vary depending on the stage of infection. While early symptoms resemble the flu, advanced stages can lead to life-threatening infections and cancers. Since HIV may remain silent for years, regular testing and early treatment are essential. With proper medical care, people living with HIV can lead long, healthy, and fulfilling lives.
