Hemorrhagic Fevers and Diseases

Hemorrhagic diseases are caused by infection with certain viruses or bacteria. Viruses cause virtually all the hemorrhagic diseases of microbiological origin that arise with any frequency. The various viral diseases are also known as viral hemorrhagic fevers. Bacterial hemorrhagic disease does occur, but rarely. One example of a bacterial hemorrhagic disease is scrub typhus.

Copious bleeding is the hallmark of a hemorrhagic disease. The onset of a hemorrhagic fever or disease can produce mild symptoms that clear up quickly. However, most hemorrhagic diseases are infamous because of the speed that some infections take hold, and the ferocity of their symptoms. Such hemorrhagic maladies, such as Ebola, have high mortality rates.
