Ebola Virus Outbreak â Is India Prepared? Ebola viral disease (EVD), also known as Ebola hemorrhagic fever (EHF) is a serious, infectious viral hemorrhagic fever (VHF) condition in humans, monkeys, gorillas, chimpanzees caused by the virus of the Filoviridae family, genus Ebolavirus.ccording to WHO, it is the health workers and the family members of the infected person who are more at risk of the Ebola fever. Treatment of the virus. Unfortunately, no vaccines have been developed so far for this virus. Some vaccines are in the trial and testing process but not yet ready for medical use.

Ebola virus disease Ebola virus disease (EVD; also Ebola hemorrhagic fever, or EHF), or simply Ebola, is a viral hemorrhagic fever of humans and other primates caused by ebolaviruses. Signs and symptoms typically start between two days and three weeks after contracting the virus with a fever, sore throat, muscular pain, and headaches.t is believed that between people, Ebola disease spreads only by direct contact with the blood or body fluids of a person who has developed symptoms of the disease. Body fluids that may contain Ebola viruses include saliva, mucus, vomit, feces, sweat, tears, breast milk, urine and semen.

Ebola Hemorrhagic Fever (Ebola Virus Disease) The four Ebola strains are termed as follows: Zaire, Sudan, Tai Forest, and Bundibugyo virus, with Zaire being the most lethal strain. A fifth strain termed Reston has been found in the Philippines. The strain infects primates, pigs, and humans and causes few if any symptoms and no deaths in humans. Most outbreaks of the more lethal strains of Ebola have occurred in Africa and mainly in small-or medium-sized towns.

- Ebola is a deadly disease caused by a virus. There are five strains, and four of them can make people sick. After entering the body, it kills cells, making some of them explode. It wrecks the immune system, causes heavy bleeding inside the body, and damages almost every organ.The virus is scary, but it’s also rare.he virus has infected thousands of people and killed more than half of them. It started in Guinea and spread to Sierra Leone, Liberia, and Nigeria. A man who traveled to the U.S. from Africa died of Ebola in October. A nurse who helped treat him came down with Ebola.

Ebola virus Transmission. Ebola is transmitted through bodily fluids and/or direct contact with infected individuals. It is believed to spread to human populations through contact with infected primates, as opposed to directly from natural reservoirs. The suspected natural sources of the virus are certain species of fruit bats.here are several different types of Ebola virus that effect humans. Currently they are Zaire, Sudan, and Ivory Coast Ebola virus, named for the respective regions in Africa in which the strain was found. Reston Ebola virus is a type of Ebola that only infects non-human primates.

- Definition. Ebola virus and Marburg virus are related viruses that cause hemorrhagic fevers — illnesses marked by severe bleeding (hemorrhage), organ failure and, in many cases, death. Both viruses are native to Africa, where sporadic outbreaks have occurred for decades.fter the initial transmission, the viruses can spread from person to person through contact with body fluids or contaminated needles. No drug has been approved to treat either virus. People diagnosed with Ebola or Marburg virus receive supportive care and treatment for complications.

Zaire ebolavirus There is a protein called the Ebola viral protein 35 (VP35) which is a cofactor for the Ebola RNA polymerase and this complex is needed for viral production(Leung et al., 2010)[28]. The virulence factor for the Zaire ebolavirus is when VP35 binds to double strand RNA (dsRNA). Recently, an end-cap was discovered for the VP35 protein, which are hydrophobic molecules attached to the end tail. This end-cap actually helps the VP35 protein bind to dsRNA(Leung et al., 2010)[29].

Ebola: Causes, Symptoms & Treatment Ebola virus disease (EVD) is a rare and often-fatal infection caused by one of the five strains of the Ebola virus. Ebola first appeared in 1976 in a simultaneous outbreak in the areas that are now Sudan and the Democratic Republic of the Congo, according to the World Health Organization (WHO).t is used to prevent the spread of the virus and to treat people who are already infected. In tests with primates, the treatment was 100 percent effective in preventing the Ebola virus from spreading, according to Tekmira's documentation.

Ebola virus Ebola virus (/ɛˈboʊlə/ ; EBOV, formerly designated Zaire ebolavirus) is one of five known viruses within the genus Ebolavirus. Four of the five known ebolaviruses, including EBOV, cause a severe and often fatal hemorrhagic fever in humans and other mammals, known as Ebola virus disease (EVD).n one study, mice with one copy of the NPC1 gene removed showed an 80 percent survival rate fifteen days after exposure to mouse-adapted Ebola virus, while only 10 percent of unmodified mice survived this long.
