Human immunodeficiency virus (HIV)

Overview

What is HIV?

Human immunodeficiency virus (HIV) is the virus that causes HIV infection. HIV affects the immune system by attacking and destroying CD4 cells. The CD4 cells are part of your immune system that help in fighting infections. Without CD4 cells, it hard for your body to fight serious infections and certain cancers, making those infected more susceptible to getting sick.1

If left untreated, HIV can destroy the immune system and can lead to Acquired Immunodeficiency Syndrome (AIDS), which is the most advanced stage of HIV infection.1

How common is HIV?

About 1.2 million people in the United States are living with HIV. This includes approximately 161,800 people who are unaware of their infection (14%). There were 37,968 new infections diagnosed in 2018.2

How is HIV transmitted?3

HIV is transmitted through contact with HIV-infected body fluids, including blood, semen, pre-seminal fluids, vaginal fluids, rectal fluids, and breast milk. HIV is mainly spread by:

  • Anal or vaginal sex with an HIV infected person without using a condom or taking medications to prevent or treat HIV
  • Sharing injection drug equipment, such as needles, with an HIV infected person
  • Mother-to-child transmission can occur from a woman with HIV to her child during pregnancy, childbirth, or breastfeeding

HIV cannot be transmitted by:

  • Shaking hands or hugging a person who has HIV
  • Sharing objects such as dishes, toilet seats, or doorknobs used by a person with HIV
  • HIV is not spread through the air or in water or by mosquitoes, ticks, or other blood-sucking insects

Can I reduce my risk of getting HIV?

Pre-exposure prophylaxis (PrEP) is also an option for people who are at high risk of becoming infected. PrEP entails taking a medication daily to prevent HIV infection and requires your health care provider to determine if you are a candidate.
