People are infectious as long as their blood and secretions contain the virus. It then spreads in the community through human-to-human transmission, with infection resulting from direct contact (through broken skin or mucous membranes) with the blood, secretions, organs or other body fluids of infected people, and indirect contact with environments contaminated with such fluids. In Africa, infection has been documented through the handling of infected chimpanzees, gorillas, fruit bats, monkeys, forest antelope and porcupines found ill or dead in the rainforest. Some fruit bats are considered to be the natural host of Ebola virus. This is followed by vomiting, diarrhoea, rash, impaired kidney and liver function, and in some cases, both internal and external bleeding.Įbola virus is introduced into the human population through close contact with the blood, secretions, organs or other body fluids of infected animals. ![]() An EVD outbreak caused by Sudan ebolavirus has been ongoing in Uganda since 19 September 2022.ĮVD is a severe acute viral illness often characterised by sudden onset of fever, intense weakness, muscle pain, headache and sore throat. An EVD outbreak involving 23 cases was reported in Guinea in 2021. After that, on and off EVD outbreaks with various scales have been reported in the Democratic Republic of the Congo from 2017 to 2022. The EVD outbreak which occurred in West Africa from March 2014 to January 2016 was the largest outbreak since Ebola virus was first discovered in 1976, affecting mainly countries including Guinea, Liberia and Sierra Leone. Confirmed cases of EVD have been reported mainly in sub-Saharan Africa including the Democratic Republic of the Congo, Gabon, South Sudan, Cote D'Ivoire, Uganda and Congo. ![]() The disease has appeared sporadically since then. EVD in humans has an average case fatality rate of around 50% (varied from 25% to 90% in previous outbreaks).ĮVD first appeared in 1976 in South Sudan and the Democratic Republic of the Congo, the latter in a village situated near the Ebola River, from which the disease took its name. Healthcare providers caring for and in close contact with Ebola patients are at the highest risk of getting sick because they may come in direct contact with the blood or body fluids of sick patients, according to the CDC.Click here to view the thematic webpage of Ebola Virus DiseaseĮbola virus disease (EVD formerly known as Ebola haemorrhagic fever) is caused by infection with Ebola virus which belongs to the family Filoviridae. Symptoms can appear two to 21 days after exposure. The incubation period - time between infection and display of symptoms - is two to 21 days. Other symptoms that develop include vomiting, diarrhea, rash, internal and external bleeding. Symptoms include the sudden onset of fever, sore throat and weakness. Unexplained bleeding inside and outside the body.Common Symptoms of EbolaĪ person infected with Ebola is not contagious until symptoms appear. Unexplained fever (greater than 38.6℃ or 101.5℉) with or without: We know how to stop Ebola’s further spread: thorough case finding, isolation of ill people, contacting people exposed to the ill person and further isolation of contacts if they develop symptoms," according to the CDC. "Ebola is not spread through casual contact therefore, the risk of an outbreak in the U.S. ![]() Medical experts say advanced healthcare systems prevent the likely of a major outbreak in the United States unlike in West Africa where thousands have died from the virus. Transmission occurs by direct contact with the blood, body fluids and tissues of infected people or animals. Ebola is not spread through casual contact, air, water and food. Becoming infected requires direct, physical contact with the bodily fluids (vomit, feces, urine, blood, semen, etc.) of people who have been infected with or died from the Ebola virus disease previously known as Ebola hemorrhagic fever. The risk of transmission is low. The current outbreak is the first in West Africa and the largest Ebola outbreak in history, according to the Centers for Disease Control and Prevention (CDC). The severe acute viral illness is often characterized by high fever, muscle pain, unexplained bleeding and severe headache. Ebola is a rare and serious disease caused by infection with one of the virus strains. Ebola virus disease, or Ebola, is one of the world’s most virulent diseases.
