The correct answer is: A. dengue fever.
Anopheles mosquitoes are the primary vectors of malaria, but they can also transmit dengue fever, filariasis, and yellow fever.
Dengue fever is a mosquito-borne tropical disease caused by the dengue virus. It is spread to people primarily through the bite of an infected Aedes aegypti mosquito. Symptoms of dengue fever include fever, headache, muscle and joint pains, and a rash. In severe cases, dengue can cause dengue hemorrhagic fever, a potentially fatal condition.
Filariasis is a parasitic disease caused by thread-like worms called filarial nematodes. It is spread to people through the bite of infected mosquitoes. Symptoms of filariasis can include fever, itching, and swelling of the lymph nodes. In severe cases, filariasis can cause elephantiasis, a condition in which the limbs and other parts of the body become grossly enlarged.
Yellow fever is a viral disease that is spread to people through the bite of an infected Aedes aegypti mosquito. Symptoms of yellow fever include fever, headache, muscle aches, and jaundice. In severe cases, yellow fever can cause bleeding and shock.
It is important to note that not all mosquitoes of the Anopheles genus are vectors of disease. Only certain species of Anopheles mosquitoes are capable of transmitting malaria.
