Which condition is described as having flu-like symptoms, lasts about a week, and is transmitted by a mosquito vector?

Dengue Fever is characterized by flu-like symptoms such as high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. The condition typically lasts about a week, after which recovery occurs; however, some individuals can develop severe forms of the disease, which can be life-threatening.

Transmission of Dengue Fever occurs via mosquitoes, primarily the Aedes aegypti species. These mosquitoes thrive in urban environments and bite during the day, making them effective vectors for spreading the virus from one host to another.

In contrast, while Malaria is also transmitted by mosquitoes, its symptoms and duration differ significantly. Zika Virus and Yellow Fever, although also transmitted by mosquito bites, present with different symptomatology and potential complications. For example, Zika Virus can go undetected in many individuals and has implications for pregnancy, while Yellow Fever often presents with more severe symptoms and is associated with a risk of liver damage and jaundice. Therefore, the defining features of flu-like symptoms, duration, and mode of transmission align closely with Dengue Fever, confirming it as the correct answer.
