Yellow Fever

Yellow Fever is indeed spread by mosquitoes. The virus is primarily transmitted to humans through the bite of infected Aedes mosquitoes, particularly Aedes aegypti. These mosquitoes are commonly found in tropical and subtropical areas, where yellow fever is endemic. When a mosquito bites an infected person, it can acquire the virus and then transmit it to other people it subsequently bites. Therefore, it is crucial to take preventive measures such as using mosquito repellents and eliminating mosquito breeding sites to control the spread of yellow fever.

Yellow Fever was classified as an epidemic because it is a contagious viral disease that spreads rapidly and affects a large number of people within a specific population or geographic area. Epidemics are characterized by the sudden and widespread occurrence of a disease, and yellow fever fits this description as it has caused numerous outbreaks throughout history, leading to significant illness and death in affected populations. Therefore, it is correct to say that yellow fever was classified as an epidemic.

The statement "Yellow Fever is an extinct illness" is false. Yellow fever is a viral disease transmitted by mosquitoes and is still present in certain parts of the world, particularly in tropical regions of Africa and South America. It is a potentially serious illness that can cause symptoms ranging from fever and headache to liver damage and hemorrhage. Vaccination is available to prevent yellow fever, but the disease is not extinct.

Yellow Fever is caused by a virus. It is transmitted to humans through the bite of infected mosquitoes. The virus belongs to the Flaviviridae family and is classified as a member of the Flavivirus genus. Yellow Fever is not caused by bacteria or parasites.
