Qu'est-ce que le virus Ebola (Ebola hemorrhagic fever)

Les symptômes du virus Ebola
Symptoms of the Ebola Virus

The ebola virus disease or EVD is a disease which affects humans and other primates, that is caused by Ebolavirus. The symptoms from ebola can start anywhere between two days and three weeks after contracting the virus. These symptoms are much like sudden influenza: a fever, that can range around 38.3 °C (100.9 °F), gorge irritée, muscle pain and a headache. Patients can experience shortness of breath, confusion and dizziness. Soon after maculopaplar rashes appear, la diarrhée et des vomissements commence, avec diminution des fonctions hépatique et rénale. Some people will experience internal and external bleeding. Tousser du sang, vomissements de sang ou de sang dans les selles, ainsi que des saignements dans le blanc des yeux peuvent également se produire. La mort peut survenir entre 6 and 16 jours après les systèmes en raison de la perte de liquide provoquant une pression artérielle basse.

The ebola virus is spread by direct contact with blood or body fluids (c'est à dire. transpiration, du sang, salive, mucus, vomir, larmes, l'urine, etc.) avec un humain ou un animal infecté. The virus can also be transmitted through a contact with surface that has been recently contaminated. BVD can also spread from breast milk or semen for several weeks to months after the patient experiences recovery. Ebola’s original carriers are believed to be fruit bats, which are able to spread the virus without being affected by it. Human became infected by having contact with these bats, or living and dead animals that were infected EbolaCycleby these bats. After humans are infected they tend to spread Ebola with other humans. Diseases such as cholera, malaria and meningitis , all resemble EVD’s spread pattern. Blood samples taken from test are analyzed for RNA, viral antibodies to confirm this diagnosis.

To control the spread of eblola, and other similar outbreaks, states and countries, must coordinate medical services as well as, is inform and engage their population. Medical services attempt to rapidly detect the virus, aussi bien que, conduct contact tracing of those who have come in contact with the infection. People who are suspected of having ebola must be tested as soon as possible with quick laboratory access. If someone has died from ebola, medical services must take proper care of the disposal of the body, through cremation or burial.

Handling of any potentially infected animals must be with protective clothing covering the face with mask and goggles and hands with gloves, with no skin being exposed. Samples of any body fluids must be handled carefully. To avoid potential wide spread outbreaks, countries with medical services must try to incorporate effective medical isolation procedures. Many countries in Africa, have not be able to contain the spread of Ebola. In Guinea, the outbreak is believed to have occurred based on un-restricted contact with infected corpse during burial rituals.

Currently there are no specific treatments for ebola available. The efforts to treat the infected are supported , through oral re-hydration therapy, ou liquides intraveineux. Les symptômes sont traités plutôt que le virus lui-même. Ces traitements de soins de soutien aux patients a tendance améliore les résultats. Ebola a un risque élevé de décès, killing between 25% and 90% des personnes infectées par le virus. Le taux moyen de décès est à 50%. EVD a d'abord été identifiée au Soudan, alors la République démocratique du Congo. This disease occurs in tropical regions of sub-Saharan Africa. À partir du 25 Octobre, 2014 this outbreak has caused nearly 14,000 cas et 5,000 des morts.
