Ebola virus disease (EVD), formerly known as Ebola haemorrhagic fever, is a severe, often fatal illness in humans. EVD outbreaks have a case fatality rate of up to 90%. EVD outbreaks occur primarily in remote villages in Central and West Africa, near tropical rainforests. The virus is transmitted to people from wild animals and spreads in the human population through human-to-human transmission. Fruit bats of the Pteropodidae family are considered to be the natural host of the Ebola virus. Severely ill patients require intensive supportive care. No licensed specific treatment or vaccine is available for use in people or animals. The Ebola outbreak currently ravaging West Africa continues to spread at an alarming rate, and the World Health Organization says that hospital beds, supplies and transportation are all in short supply. The United Nations agency announced last week that it had developed a $490 million program for the U.N.’s network of agencies to implement. But that money is not immediately available because the WHO is “badly” funded, spokesman Dan Epstein told the International Business Times on Monday. American doctor back in hospital: An American patient treated for Ebola in Nebraska and then released is now in isolation in a hospital in Massachusetts. Dr. Richard Sacra went to an emergency room early Saturday in Boston with a cough and fever, according to the missionary organization Serving in Mission. He was afraid he might have pneumonia. Because of his previous infection, he was transferred to the UMass Memorial Medical Center in Worcester, the center said in a statement. Doctors there don't believe his symptoms point to a recurrence of Ebola but instead a respiratory infection. But they are keeping Sacra in isolation in accordance with guidelines from the CDC until the health institute gives the all-clear. "We're waiting for final test results from the CDC, which we expect to receive late Monday," said lead physician Dr. Robert Finberg. Sacra had worked as a medical missionary in Liberia but not directly with Ebola patients. Nevertheless, he contracted the disease. He was treated in isolation at the Nebraska Medical Center in Omaha and then released after testing negative for the virus. How will this project solve this problem? This fund will ensure that aid organizations on the ground in West Africa have the resources they need to stop the outbreak. Funds will be used for medical supplies to care for those already infected, protective equipment to keep health workers safe, and educational campaigns to inform the public about Ebola and how it spreads. 2014 West Africa Outbreak: (Full historical timeline at bottom) Cases listed below include confirmed, probable or suspected cases of Ebola as of September 23, 2014 (World Health Organization and CDC): Guinea - 1074 cases, 648 deaths Liberia - 3458 cases, 1830 deaths Nigeria - 20 cases, 8 deaths Senegal - 1 case, 0 deaths Sierra Leone - 2021 cases, 605 deaths Donated Funds will go to the provision of the following: Anti-bacterial soap Bleach based germicidal Clorox wipes Purell Instant Hand Sanitizer, 4oz flip-cap bottle PURELL Premoistened Sanitizing Hand Wipes, 5 x 7, 100/Box Baby Wipes Disposable Diapers Clorox Disinfecting Wipes Plastic Gloves donations to purchase Ready-To-Use Therapeutic Food (for children in quarantined communities that have already started experiencing food shortages) Experts at the World Health Organization declare the Ebola epidemic ravaging West Africa an international health emergency that requires a coordinated global approach, describing it as the worst outbreak in the four-decade history of tracking the disease.
