What disease is caused by a filovirus and characterized by hemorrhagic fever?

The disease characterized by hemorrhagic fever caused by a filovirus is Ebola. Ebola Virus Disease (EVD) is a severe and often deadly illness that manifests with high fever, bleeding, and organ failure. It is transmitted through direct contact with bodily fluids of infected individuals, which is a key aspect of its transmission dynamics.

Ebola virus is a member of the Filoviridae family, specifically classified under the genus Ebolavirus. The disease is notorious for its high mortality rates and the severity of its symptoms, which can escalate rapidly after infection. This contrasts with options like HIV and influenza, which are caused by different virus families and present with different clinical features. Malaria, on the other hand, is caused by parasites, not viruses. Hence, the identification of Ebola as the correct answer lies in its specific causative agent, the filovirus, and the unique presentation of hemorrhagic fever associated with the disease.
