The virus destroys a type of white blood cell in the immune system called a T-helper cell, and makes copies of itself inside these cells. T-helper cells are also referred to as CD4 cells.

How it spreads

HIV is spread only in certain body fluids from a person infected with HIV. These fluids are blood, semen, pre-seminal fluids, rectal fluids, vaginal fluids, and breast milk. In the United States, HIV is spread mainly by having sex or sharing injection drug equipment, such as needles, with someone who has HIV.

What it does

For the most part, the symptoms of HIV are the result of infections caused by bacteria, viruses, fungi, and/or parasites. 

These conditions do not normally develop in individuals with healthy immune systems, which protect the body against infection.


Symptoms of early HIV infection

Many people with HIV have no symptoms for several months to even years after becoming infected. Others may develop symptoms similar to flu, usually 2-6 weeks after catching the virus. 

The symptoms of early HIV infection may include:

  • fever
  • chills
  • joint pain
  • muscle aches
  • sore throat
  • sweats (particularly at night)
  • enlarged glands
  • a red rash
  • tiredness
  • weakness
  • unintentional weight loss
If left untreated, HIV weakens the ability to fight infection. The person becomes vulnerable to serious illnesses. This stage of infection is known as AIDS.

Symptoms of late-stage HIV infection may include:

  • blurred vision
  • diarrhea, which is usually persistent or chronic
  • dry cough
  • fever of above 100 °F (37 °C) lasting for weeks
  • night sweats
  • permanent tiredness
  • shortness of breath (dyspnea)
  • swollen glands lasting for weeks
  • unintentional weight loss
  • white spots on the tongue or mouth
During late-stage HIV infection, the risk of developing a life-threatening illness is much greater. Life-threatening illnesses may be controlled, avoided,and/or treated with proper medications, often including HIV treatment.

Myths about aids

There are many misconceptions about HIV and AIDS. The virus CANNOT be transmitted from:

  • shaking hands
  • hugging
  • casual kissing
  • sneezing
  • touching unbroken skin
  • using the same toilet
  • sharing towels
  • sharing cutlery
  • mouth-to-mouth resuscitation
  • or other forms of "casual contact"
