**Question:** Acedes aegypticus transmits -

A. Cholera
B. Dengue fever
C. Malaria
D. Yellow fever

**Correct Answer:** D. Yellow fever

**Core Concept:** Acedes aegypticus is a mosquito species that acts as a vector for various infectious diseases. In this case, the correct answer is D. Yellow fever, which is transmitted by the same mosquito species.

**Why the Correct Answer is Right:** Acedes aegypticus, also known as the Aedes mosquito, is a carrier of several diseases due to its role as a vector. It plays a significant role in transmitting viruses and bacteria to humans and animals. Among the given options, Yellow fever is the correct disease transmitted by Aedes mosquitoes. Yellow fever is a viral hemorrhagic fever caused by the Yellow fever virus (family Flaviviridae, genus Flavivirus). It affects humans and non-human primates, leading to severe symptoms such as jaundice, hemorrhage, and organ dysfunction.

**Why Each Wrong Option is Incorrect:**

A. Cholera (Aedes aegypti is another mosquito species responsible for transmitting cholera, not Aedes aegypticus.)
B. Dengue fever (Aedes aegypticus is a vector for dengue fever, but the correct answer is Aedes albopictus.)
C. Malaria (Aedes aegypticus is a vector for malaria, but the correct answer is Anopheles mosquitoes.)

**Clinical Pearl:** Understanding the vector-borne diseases transmitted by Aedes mosquitoes is crucial for healthcare professionals, especially in regions with high mosquito prevalence. Proper knowledge of disease vectors helps in implementing effective control measures and preventing outbreaks.
