Correct option is B
Sol. Dengue fever typically presents with sudden high-grade fever, severe muscle and joint pain (called “breakbone fever”), retro-orbital pain (behind the eyes), headache, and rash. Low-grade fever is not characteristic of dengue and may indicate a mild viral illness instead. Dengue is transmitted by Aedes aegypti mosquitoes, and early detection is key to prevent complications like hemorrhage or shock.
Explanation of each option:
· (a) High Fever – Correct. A fever of 103°F–105°F is a classical sign, appearing suddenly and lasting several days.
· (b) Low-grade Fever – Incorrect. Dengue usually begins with high fever, not low-grade. This makes it uncharacteristic of the disease.
· (c) Eye pain – Correct. Retro-orbital pain is a distinctive symptom, especially when moving the eyes or during fever spikes.
· (d) Joint pain – Correct. Joint and muscle pain are intense, earning dengue the name "breakbone fever" due to its severity.
