KENEMA, Sierra Leone, 6 August 2014 – As the outbreak of Ebola virus in West Africa continues to spread, health workers in Sierra Leone are risking their lives in the effort to contain the deadly disease.
Similarly, it is asked, what parts of the world are affected by Ebola?
More than 21 months on from the first confirmed case recorded on 23 March 2014, 11,315 people have been reported as having died from the disease in six countries; Liberia, Guinea, Sierra Leone, Nigeria, the US and Mali. The total number of reported cases is about 28,637.
How many people in the world have been infected with Ebola?
DAKAR, Senegal -- More than 10,000 people have been infected with Ebola and nearly half of them have died, according to figures released Saturday by the World Health Organization, as the outbreak continues to spread.
Catching Ebola from someone else requires “close and direct” contact with infected body fluids, the WHO says. The most infectious body fluids are blood, stool, and vomit. The virus has also been found in breast milk and urine -- and in semen for up to 70 days, though those fluids are considered to be less infectious.
Ebola's Family Tree: Disease May Have Existed For 23 Million Years, Much Longer Than Previously Believed. A family of viruses that Ebola belongs to may have existed over 20 million years ago, according to a new study published in the journal PeerJ.
Upon entering the body, the virus targets specific cell types, including liver cells, cells in the immune system, and endothelial cells, which line the inside of blood vessels. Once inside the cells, one of the proteins made by the virus is called Ebola virus glycoprotein .
The best way to avoid Ebola is to stay away from areas where the virus is common. If you are in an outbreak area: Avoid infected people, their body fluids, and the bodies of anyone who has died from the disease. Avoid contact with wild animals, like bats and monkeys, and their meat.
But the history of the Ebola virus goes back further. It was first identified in Zaire (modern day Democratic Republic of the Congo) in 1976. The first victim was a schoolmaster in the village of Yambuku in the north of the country. The disease got its name from the nearby Ebola River, a tributary of the Congo River.
Currently, there is no specific medical treatment for Ebola hemorrhagic fever according to the CDC. The CDC recommends the following medical treatments for Ebola-infected patients: Providing intravenous fluids (IV) and balancing electrolytes (body salts) Maintaining oxygen status and blood pressure.
Ebola Virus Disease (EVD) is a rare and deadly disease most commonly affecting people and nonhuman primates (monkeys, gorillas, and chimpanzees). It is caused by an infection with one of five known Ebola virus species, four of which can cause disease in people: Ebola virus (Zaire ebolavirus)
The West African Ebola virus epidemic (2013–2016) was the most widespread outbreak of Ebola virus disease (EVD) in history—causing major loss of life and socioeconomic disruption in the region, mainly in the countries of Guinea, Liberia, and Sierra Leone.
People who die from infection with Ebola virus usually end up dying from multi-organ failure and shock. "The shock is from the bleeding -- now you're bleeding in different parts of your body, and the blood is leaking out of your blood vessels," Bhadelia explained.
At least two of these fruit bat species are also found in Guinea — which is where the current Ebola outbreak in West Africa began — so it's possible that these bats were sources for the outbreak, Gatherer told Live Science.
Although clinicians readily agree that the Ebola virus leaps from one person to the next via close contact with blood and other bodily fluids, Osterholm warned that the risk of airborne transmission is “real” and “until we consider it, the world will not be prepared to do what is necessary to end the epidemic.”
Proteins released by immune cells create widespread inflammation, which can damage the tissue lining blood vessels, causing them to leak. Macrophages, a type of immune cell that Ebola infects, release proteins that cause clots in the bloodstream, blocking blood flow to organs such as the liver and kidneys.
In fact, the epidemic killed five times more than all other known Ebola outbreaks combined. More than 21 months on from the first confirmed case recorded on 23 March 2014, 11,315 people have been reported as having died from the disease in six countries; Liberia, Guinea, Sierra Leone, Nigeria, the US and Mali.
The Ebola virus outbreak that's ravaging West Africa probably started with a single infected person, a new genetic analysis shows. This West African variant can be traced genetically to a single introduction, perhaps a person infected by a bat, researchers report in the journal Science.
If doctors suspect you have Ebola or Marburg hemorrhagic fever, they use blood tests to quickly identify the virus, including: Enzyme-linked immunosorbent assay (ELISA) Reverse transcriptase polymerase chain reaction (PCR)
As of May 2015, 507 health-care workers have died from Ebola. More than 800 contracted the disease. To put that into context, in the second biggest outbreak in history — in Zaire in 1976 — 11 medical personnel died.
Ebola viruses are found in several African countries. Since Ebola was first recognized in 1976, the disease has been rare and occurred in sporadic outbreaks in west and central Africa. However, the 2014 outbreak has involved more cases and deaths than all other outbreaks combined.
Ebola then spreads through human-to-human transmission via direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other bodily fluids of infected people, and with surfaces and materials (e.g. bedding, clothing) contaminated with these fluids.
