Definition

Noun: A severe, often fatal, multisystem syndrome caused by infection with certain viruses. It is characterized by fever, fatigue, dizziness, muscle aches, and bleeding (hemorrhage) from internal organs, skin, and mucous membranes. These diseases are often zoonotic and may be geographically restricted.

Usage

The term is used in medical and public health contexts to classify and discuss a specific category of dangerous infectious diseases. - The outbreak was identified as a viral haemorrhagic fever, prompting immediate quarantine measures. - Researchers are studying the transmission patterns of various viral haemorrhagic fevers.

Advanced Usage
  • As a public health threat: The term is often used to describe diseases with epidemic potential that require high-level biocontainment.
    • The hospital activated its special isolation unit for suspected cases of viral haemorrhagic fever.
  • In differential diagnosis: Used by clinicians when a patient presents with a specific set of severe symptoms and a relevant travel history.
    • Given the patient's symptoms and recent travel to West Africa, viral haemorrhagic fever is a primary concern.
Variants and Related Words

  • VHF: A common acronym or initialism for the full term.
  • Hemorrhagic fever virus: Refers to the specific virus that causes the disease (e.g., Ebola virus, Marburg virus, Lassa virus).
Synonyms

Related Phrases and Terms
  • Capillary hemorrhage: A key pathological feature of these diseases, referring to bleeding from the smallest blood vessels.
  • Zoonotic transmission: A common mode of spread for many viral haemorrhagic fevers, indicating transfer from animals to humans.
  • Biosafety Level 4 (BSL-4): The highest level of biocontainment required for working with agents that cause diseases like viral haemorrhagic fevers.
Noun
  1. a group of illnesses caused by a viral infection (usually restricted to a specific geographic area); fever and gastrointestinal symptoms are followed by capillary hemorrhage
