Virology is the scientific study of biological viruses. It is a subfield of microbiology that focuses on their detection, structure, classification and evolution, their methods of infection and exploitation of host cells for reproduction, their interaction with host organism physiology and immunity, the diseases they cause, the techniques to isolate and culture them, and their use in research and therapy.
Filoviridae is a family of single-stranded negative-sense RNA viruses in the order Mononegavirales. Two members of the family that are commonly known are Ebola virus and Marburg virus. Both viruses, and some of their lesser known relatives, cause severe disease in humans and nonhuman primates in the form of viral hemorrhagic fevers.
The genus Marburgvirus is the taxonomic home of Marburg marburgvirus, whose members are the two known marburgviruses, Marburg virus (MARV) and Ravn virus (RAVV). Both viruses cause Marburg virus disease in humans and nonhuman primates, a form of viral hemorrhagic fever. Both are select agents, World Health Organization Risk Group 4 Pathogens, National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogens, Centers for Disease Control and Prevention Category A Bioterrorism Agents, and are listed as Biological Agents for Export Control by the Australia Group.
Venezuelan hemorrhagic fever (VHF) is a zoonotic human illness first identified in 1989. The disease is most prevalent in several rural areas of central Venezuela and is caused by Guanarito mammarenavirus (GTOV) which belongs to the Arenaviridae family. The short-tailed cane mouse is the main host for GTOV which is spread mostly by inhalation of aerosolized droplets of saliva, respiratory secretions, urine, or blood from infected rodents. Person-to-person spread is possible, but uncommon.
Clarence James Peters, Jr is a physician, field virologist and former U.S. Army colonel. He is noted for his efforts in trying to stem epidemics of exotic infectious diseases such as the Ebola virus, Hanta virus and Rift Valley fever (RVF). He is an eminent authority on the virology, pathogenesis and epidemiology of hemorrhagic fever viruses.
The species Bundibugyo ebolavirus is the taxonomic home of one virus, Bundibugyo virus (BDBV), that forms filamentous virions and is closely related to the infamous Ebola virus (EBOV). The virus causes severe disease in humans in the form of viral hemorrhagic fever and is a Select agent, World Health Organization Risk Group 4 Pathogen, National Institutes of Health/National Institute of Allergy and Infectious Diseases Category A Priority Pathogen, Centers for Disease Control and Prevention Category A Bioterrorism Agent, and is listed as a Biological Agent for Export Control by the Australia Group.
Reston virus (RESTV) is one of six known viruses within the genus Ebolavirus. Reston virus causes Ebola virus disease in non-human primates; unlike the other five ebolaviruses, it is not known to cause disease in humans, but has caused asymptomatic infections. Reston virus was first described in 1990 as a new "strain" of Ebola virus (EBOV). It is the single member of the species Reston ebolavirus, which is included into the genus Ebolavirus, family Filoviridae, order Mononegavirales. Reston virus is named after Reston, Virginia, US, where the virus was first discovered.
Marburg virus (MARV) is a hemorrhagic fever virus of the Filoviridae family of viruses and a member of the species Marburg marburgvirus, genus Marburgvirus. It causes Marburg virus disease in primates, a form of viral hemorrhagic fever. The virus is considered to be extremely dangerous. The World Health Organization (WHO) rates it as a Risk Group 4 Pathogen. In the United States, the National Institute of Allergy and Infectious Diseases ranks it as a Category A Priority Pathogen and the Centers for Disease Control and Prevention lists it as a Category A Bioterrorism Agent. It is also listed as a biological agent for export control by the Australia Group.
Ebola, also known as Ebola virus disease (EVD) and Ebola hemorrhagic fever (EHF), is a viral hemorrhagic fever in humans and other primates, caused by ebolaviruses. Symptoms typically start anywhere between two days and three weeks after infection. The first symptoms are usually fever, sore throat, muscle pain, and headaches. These are usually followed by vomiting, diarrhoea, rash and decreased liver and kidney function, at which point some people begin to bleed both internally and externally. It kills between 25% and 90% of those infected – about 50% on average. Death is often due to shock from fluid loss, and typically occurs between six and 16 days after the first symptoms appear. Early treatment of symptoms increases the survival rate considerably compared to late start. An Ebola vaccine was approved by the US FDA in December 2019.
Zaire ebolavirus, more commonly known as Ebola virus, is one of six known species within the genus Ebolavirus. Four of the six known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD). Ebola virus has caused the majority of human deaths from EVD, and was the cause of the 2013–2016 epidemic in western Africa, which resulted in at least 28,646 suspected cases and 11,323 confirmed deaths.
Christopher Mores is an American (US) arbovirologist, trained in infectious disease epidemiology. He is a professor in the Department of Global Health at the Milken Institute School of Public Health, the program director for the Global Health Epidemiology and Disease Control MPH program, and is director of a high-containment research laboratory at the George Washington University in Washington, DC.
José Esparza is a Venezuelan American virologist who lives in the USA. He is known for his efforts to promote the international development and testing of vaccines against HIV/AIDS. During 17 years he pursued an academic career at the Venezuelan Institute for Scientific Research (IVIC), attaining positions as full professor of virology and chairman of its Department of Microbiology and Cell Biology. From 1986 to 2014 he worked continuously as a viral vaccine expert and senior public health adviser for international health policy agencies such as the World Health Organization, the Joint United Nations Programme on HIV/AIDS, and the Bill & Melinda Gates Foundation. José G. Esparza is currently an adjunct professor of medicine, at the Institute of Human Virology. During 2016 he was the president of the Global Virus Network. In the context of historical studies on the early use of horsepox for smallpox vaccination, Esparza was appointed in 2018 as a Robert Koch Fellow at the Robert Koch Institute in Berlin, Germany. He is an active member of the Latin American Academy of Sciences, ACAL.
Oyewale Tomori is a Nigerian professor of virology, educational administrator, and former vice chancellor of Redeemer's University.
Robert Ellis Shope was an American virologist, epidemiologist and public health expert, particularly known for his work on arthropod-borne viruses and emerging infectious diseases. He discovered more novel viruses than any person previously, including members of the Arenavirus, Hantavirus, Lyssavirus and Orbivirus genera of RNA viruses. He researched significant human diseases, including dengue, Lassa fever, Rift Valley fever, yellow fever, viral hemorrhagic fevers and Lyme disease. He had an encyclopedic knowledge of viruses, and curated a global reference collection of over 5,000 viral strains. He was the lead author of a groundbreaking report on the threat posed by emerging infectious diseases, and also advised on climate change and bioterrorism.
The Global Virus Network (GVN) is an international coalition of medical virologists whose goal is to help the international medical community by improving the detection and management of viral diseases. The network was founded in 2011 by Robert Gallo in collaboration with William Hall and Reinhard Kurth, and 24 countries were members of the network as of 2015. The GVN fosters research into viruses that cause human disease to promote the development of diagnostics, antiviral drugs and vaccines, and its mission includes strengthening scientific training and response mechanisms to viral outbreaks. The GVN has organized task forces for chikungunya, human T-lymphotropic virus, and Zika. The network is headquartered at the Institute of Human Virology at the University of Maryland School of Medicine, and Gallo serves as its scientific director.
