What are the various routes by which transmission of human immuno-deficiency virus takes place?

Correct Answer

The transmission of Human Immuno-deficiency Virus (HIV) generally occurs through the following routes:

  1. Sexual contact with an infected person.

  2. Transfusion of contaminated blood and blood products.

  3. Sharing infected needles, especially in the case of intravenous drug abusers.

  4. From infected mother to her child through placenta during pregnancy.

It is important to note that HIV/AIDS spreads only through body fluids and is not spread by mere touch or physical contact. Therefore, HIV/AIDS infected persons should not be isolated from family and society.
