What do Viral Hemorrhagic Fevers include?

Viral Hemorrhagic Fevers (VHFs) are a group of illnesses caused by several distinct families of viruses that can lead to severe and often fatal disease characterized by fever, bleeding, and multi-organ dysfunction. The correct answer includes Ebola and Yellow fever, both of which are well-documented examples of VHFs.

Ebola virus disease, caused by the Ebola virus, is known for its high mortality rate and the severe symptoms that accompany infection, including internal and external bleeding. Yellow fever, on the other hand, is caused by the yellow fever virus and can also lead to hemorrhagic manifestations along with liver damage and acute febrile illness. Both of these diseases illustrate the critical nature of VHFs, as they require careful medical management and have implications for public health, especially in endemic regions.

In contrast, the other options provided do not fit the criteria for VHFs. Measles and Rubella are viral infections that cause respiratory symptoms and rashes rather than hemorrhagic symptoms. Shingles and Herpes are caused by the varicella-zoster virus and herpes simplex viruses, respectively, and while they can cause significant discomfort and complications, they do not result in the classic hemorrhagic symptoms associated with VHFs.
