With regard to the transmission of human immunodeficiency virus (HIV), which among of the following statements is not correct?
1 The chances of transmission from female to male are twice as likely from male to female.
2 The chances of transmission are more if a person suffers from other sexually transmitted infections.
3 An infected mother can transmit the infection to her baby during pregnancy at child birth.
4 The risk of contacting infection from transfusion of infected blood is much higher than an exposure to contaminated needle.
Explanation:
Transmission of HIV-infection generally occurs by sexual contact with infected person, by transfusion of contaminated blood and blood products, by sharing infected needles as in the case of intravenous drug abusers and from infected mother to her child through placenta.

In which blood corpuscles, the HIV undergoes replication and produces progeny viruses?
1 TH cells
2 B-lymphocytes
3 Basophils
4 Eosinophils
Explanation:
HIV enters into helper T-lymphocytes (TH), replicates and produces progeny viruses. The progeny viruses released into blood attack other helper lymphocytes

During replication of retrovirus (HIV) A. Viral DNA is produced by reverse transcriptase B. Viral RNA gets incorporated into host genome. C. New viral RNA are produced by infected cells. D. New viral DNA are produced by infected cells.
1 A & C are correct
2 B & C are correct
3 Only A is correct
4 Only D is correct
Explanation:
Incorrect statements can be correcred as : B: viral DNA gets incorporated into host cell's DNA. D: new viral RNA is produced by infected cells.

HIV decreases natural immunity of the body by
1 Destroying antibodies
2 Destroying erythrocytes
3 Attacking T-lymphocytes
4 Attacking B-lymphocytes
Explanation:
HIV enters into helper T-lymphocytes (TH ), replicates and produce progeny viruses. The progeny viruses released in the blood attack other helper T-lymphocytes. This is repeated leading to a progressive decrease in the number of helper Tlymphocytes in the body of the infected person. This decreases natural immunity of the body.
