AIDS virus enter the human body through
A. Food
B. Kissing
C. Water
D. Blood

Answer 1

Hint: Human Immunodeficiency Virus (HIV) is a virus that attacks the body’s immune system and if not treated can lead to Acquired Immunodeficiency Syndrome (AIDS). There is no effective cure once a person gets HIV; they have it for their entire life.

Complete answer:
AIDS is entered into the body mainly in three ways:
Through sexual act: It is a major route of HIV transmission from an infected partner to the other partner.
Transmission through blood transfusion and contaminated syringes: It occurs if the person uses contaminated syringes and needles or other material by which blood gets infected.
Transmission from mother to baby: Pregnant woman can transfer AIDS to her baby through the placenta before birth or through milk feeding after birth.
HIV enters the T cells of the healthy person by endocytosis. It releases its viral RNA into the cytoplasm of the host cell along the enzyme reverse transcriptase. The DNA is then circulated into the human chromosome and DNA is transcribed to form RNA. Membrane proteins are synthesized and assembled with the viral RNA and new viral particles are released. HIV thus shattered the immunity of the victim because it destroys T lymphocytes in the body.

Hence, the correct option is D. Blood.

Note: The AIDS is infected by the blood as when the infected material gets contacted with the blood the HIV virus particles transmit through the blood into the whole body.
