Sanchez A, Geisbert TW, Feldmann H. Filoviridae: Marburg and Ebola viruses. This manuscript review and update current knowledge with regard to epidemiology of EVD problem statement, historical perspective, agent, host, environment, reservoir of infection, routes of transmission, pathogenesis, clinical features, laboratory diagnosis, management, and control. https://www.cdc.gov/amd/stories/ebola.html. 2004 Jan;10(1):40-7. Symptoms of EVD include fever, severe headache, muscle or joint pain, weakness, fatigue, sore throat, loss of appetite, diarrhea, vomiting, abdominal (stomach) pain, and, in some cases, unexplained hemorrhage (bleeding or bruising). The most recent outbreak of 2014 has set the alarm bell ringing across the globe for increased focus, funding, research, and development toward the control and management of this emerging viral communicable disease that has a potential pandemic threat. Monoclonal antibodies are proteins produced in a laboratory or other manufacturing facility that act like natural antibodies to stop a germ such as a virus from multiplying after it has infected a person. In this interview conducted at Pittcon 2023 in Philadelphia, Pennsylvania, we spoke to Dr. Chad Merkin, Director of the International Institute for Nanotechnology, about his work developing next-generation nanomaterials for medical applications.

Disease outbreak news: Ebola virus disease - Democratic Republic of the Congo. World Health Organization. As a transmittable disease, progression of the virus had been thought to be linked to higher probabilities of transmission, and therefore safety of persons in contact with infected patients was in question (Yamin et al., 2015). The second drug, Ebanga, is a single monoclonal antibody and was approved in December 2020. Between March and May of 2014, the WHO sent more than 100 experts to aid in the control of the outbreak. It was observed that the level of uncertainty for the estimations is relatively high which may hinder to make some predictions for the future evolution of EVD outbreak. There have been many very deadly cases of Ebola - the fatality rate is estimated to from about fifty to ninety percent. There are several steps to take to prevent EVD when living in or traveling to an area with EVD: The FDA approved the Ebola vaccine rVSV-ZEBOV (called Ervebo) on December 19, 2019.

The disease was then contained, however sporadic outbreaks of the Zaire and Sudan Ebola subtypes have risen in the Democratic Republic of the Congo, Gabon, Uganda, and Sudan; one of the latest outbreaks was in the Democratic Republic of the Congo in September of 2007. Ebola Virus: Pathogenesis and Countermeasure Development. In this study, the new epidemiological features and prevalence trends for EVD in Guinea, Liberia, and Sierra Leone are described. Non-human primates represent a source of infection for humans, but they are considered an accidental host (akin to humans) and not a reservoir of infection. There were scant resources, limited infrastructure, poor training on infection prevention and control and a severe shortage of health care workers with a ratio of 1.9 workers for every 10,000 people. 2011 Jul;17(7):964-76. https://onlinelibrary.wiley.com/doi/10.1111/j.1469-0691.2011.03535.x/full, http://www.ncbi.nlm.nih.gov/pubmed/21722250?tool=bestpractice.com.

Two treatments have been approved by the U.S. Food and Drug Administration (FDA) to treat Ebola virus disease caused by one strain of the Ebola virus (species Zaire ebolavirus), in adults and children. It is transmitted by means of contact with infected blood, mucous membranes, semen and other secretions, therefore being skin lesions and sexual contact significant ways of transmission (Boulton, 2014).
