Which of the following can transmit AIDS in healthy individuals?

AIDS (acquired immunodeficiency syndrome) is a sexually transmitted disease caused by the human immunodeficiency virus (HIV).

The virus can transmit in various ways:

• Direct sexual contact with the HIV-positive person
• During a blood transfusion
• From an infected mother to her baby through breast milk
• Sharing needles for injecting drugs

AIDS does not spread by hugging an HIV-infected person, holding and shaking his hands, sitting next to him, or sharing and eating food together.
