Show Hint
Small pox is caused by the variola virus, not the morbilli virus. Always verify the virus responsible for a specific disease.
Updated On: Mar 6, 2026
- Yellow fever -- Flavi virus
- Swine flu -- H1N1 virus
- Small pox -- Morbilli virus
- AIDS -- Retro virus
Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understanding the viruses.
Small pox is caused by the variola virus, not the morbilli virus, which causes measles. Other pairs in the options are correct.
Step 2: Analyzing the options.
(A) Yellow fever -- Flavi virus: Correct. Yellow fever is caused by the Flavi virus.
(B) Swine flu -- H1N1 virus: Correct. Swine flu is caused by the H1N1 strain of influenza virus.
(C) Small pox -- Morbilli virus: Incorrect. Small pox is caused by the variola virus, not the morbilli virus.
(D) AIDS -- Retro virus: Correct. AIDS is caused by the retrovirus HIV.
Step 3: Conclusion.
The incorrect pair is (C) Small pox -- Morbilli virus, as small pox is caused by the variola virus.
Small pox is caused by the variola virus, not the morbilli virus, which causes measles. Other pairs in the options are correct.
Step 2: Analyzing the options.
(A) Yellow fever -- Flavi virus: Correct. Yellow fever is caused by the Flavi virus.
