Question

Aedes aegypti, a vector for an infectious tropical disease characterised by fever, extreme pain in joints and muscles is
(A) Dengue fever
(B) Breakbone fever
(C) Typhus fever
(D) Hypofever
Choose the correct answer from the options given below:

• A. (A) and (D) only
• B. (A), (B) and (C) only
• C. (A) and (B) only
• D. (B), (C) and (D) only

Hint:

Dengue fever and Breakbone fever are synonymous. Both are viral diseases transmitted by the bite of the female Aedes aegypti mosquito.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
The mosquito Aedes aegypti acts as a vector for several tropical viral infections.
It transmits viruses belonging to the family Flaviviridae and Togaviridae, which cause debilitating symptoms in human hosts.
Detailed Explanation:
The tropical disease transmitted by Aedes aegypti characterized by fever, headache, and severe muscle and joint pain is Dengue fever.
Because the joint and muscle pain associated with this disease is so intense that it mimics the sensation of bones breaking, it is commonly called "Breakbone fever".
Therefore, statements (A) and (B) describe the exact same clinical condition.
Typhus fever (C) is a bacterial infection caused by Rickettsia species and is primarily transmitted by lice, fleas, or mites, not by Aedes aegypti.
Hypofever (D) is not a medically recognized term for a vector-borne viral disease.
As a result, only options (A) and (B) are correct.

Step 2: Final Answer:
The correct combination is (A) and (B) only, corresponding to option (3).
