  • Ebola virus disease (EVD) (aka. ebola haemorrhagic fever (EHF) & simply Ebola) is a hemorrhagic fever that affects human beings and primates.
  • New cases were reported in mid-2014 at the westernmost part of Africa in Guinea, Liberia, Sierra Leone and Nigeria.
  • As of 2015, Ebola continues to make a steady advance around the world with 20,416 reported cases resulting in 8,004 deaths. See Wikipedia's Ebola virus disease.
  • Ebola cases are due to human-to-human (H2H) transmission; the EBV incubation period from the time of infection to symptoms is 2 to 21 days; EBV survival rates in 2014 have been higher (~47%) than previous outbreaks.
  • The first Ebola case was diagnosed in the United States in 2014 which set off a firestorm of media scrutiny and recriminations. As of December 2014, Canada has had several false alarms with suspected but no confirmed cases.

new2.gif What to look for? Signs and symptoms of Ebola infection

A person infected with the Ebola virus is not contagious until symptoms appear. Symptoms usually begin eight to 10 days after someone has been exposed to the virus that causes Ebola. However, they may begin to appear later even up to 21 days after exposure. Typical signs and symptoms of Ebola infection are:

  • Fever (greater than 101.5F)
  • Severe headache
  • Muscle pain
  • Vomiting
  • Diarrhea
  • Stomach pain
  • Unexplained bleeding or bruising

If you have a few of the above symptoms, you should see your doctor. Only qualified physicians and health professionals will be able to examine you properly e.g., they take your health history, examine you and bring their expertise and experience to bear on evaluating you whether or not you have an infectious illness. Advice regarding your care must include your physician and other health professionals.

Searching MEDLINE

  • The primary research literature on Ebola (the disease, virus and infection) can be found via PubMed, EMBASE and other public health websites and databases.
  • A simple PubMed search for ebola* will retrieve all citations indexed with any of the Ebola MeSH headings as well as citations that have not yet been indexed but have that root string as a text word. Search truncation turns off Automatic Term Mapping and explosions in PubMed; however, with this search none of the Ebola MeSH headings have narrower terms at this time in their MeSH hierarchy, so nothing is lost by truncation. The MeSH Vocabulary places the Ebola virus (MeSH: Ebolavirus) in the Organisms tree and the infection (MeSH: Hemorrhagic Fever, Ebola) in the Diseases tree (see below). Indexing policy dictates that indexers coordinate the infection and virus when appropriate. In addition, searchers may be interested in the MeSH term Ebola Vaccines in the Chemicals and Drugs tree to find the literature on that specific topic.
  • Use medical subject headings in MEDLINE for indexed articles (or browse new items via this PubMed keyword search for "Ebola"):
  • Vaccines or candidate vaccines used to prevent EBOLA HEMORRHAGIC FEVER.
  • Year introduced: 2005
  • A highly fatal, acute hemorrhagic fever, clinically very similar to MARBURG VIRUS DISEASE, caused by EBOLAVIRUS, first occurring in the Sudan and adjacent northwestern (what was then) Zaire.
  • Year introduced: 1996
  • A genus in the family FILOVIRIDAE consisting of several distinct species of Ebolavirus, each containing separate strains. These viruses cause outbreaks of a contagious, hemorrhagic disease (HEMORRHAGIC FEVER, EBOLA) in humans, usually with high mortality.
  • Year introduced: 2007 (2002)
