How is an HIV infection different from a cold virus infection?

HIV Infection

* Caused by the human immunodeficiency virus (HIV)

* Attacks the immune system, specifically CD4+ T cells (also known as helper T cells)

* Can lead to acquired immunodeficiency syndrome (AIDS) if left untreated

* Transmitted through contact with infected blood, semen, vaginal fluids, or breast milk

* Symptoms may include fever, rash, sore throat, muscle aches, fatigue, and weight loss

* Treatment involves antiretroviral therapy (ART), which can suppress the virus and prevent it from progressing to AIDS

Cold Virus Infection

* Caused by a variety of viruses, most commonly rhinoviruses

* Attacks the respiratory system, causing inflammation and irritation

* Usually resolves on its own within 7-10 days

* Transmitted through contact with infected respiratory droplets or surfaces

* Symptoms may include runny nose, sneezing, sore throat, cough, headache, and body aches

* Treatment involves rest, fluids, and over-the-counter medications to relieve symptoms
