Pls read and know it , Ebola virus disease(EVD) orEbola hemorrhagic fever(EHF) is a disease of humans and other primatescaused by an ebolavirus. Symptoms start two days to three weeks after contracting the virus, with a fever, sore throat, muscle painand headaches. Typically, vomiting, diarrheaand rashfollow, along with decreased functioning of the liverand kidneys. Around this time, affected people may begin to bleedboth within the bodyand externally. [ 1 ] The virus may be acquired upon contact with bloodor bodily fluidsof an infected animal. [ 1 ]Spreading through the air has not been documented in the natural environment. [ 2 ]Fruit bats are believed to carry and spread the virus without being affected. Once human infection occurs, the disease may spread between people, as well. Male survivors may be able to transmit the disease via semenfor nearly two months. To make the diagnosis, typically other diseases with similar symptoms such as malaria, choleraand other viral hemorrhagic feversare first excluded. To confirm the diagnosis, blood samples are tested for viral antibodies, viral RNA, or the virus itself. [ 1 ] Prevention includes decreasing the spread of disease from infected animals to humans. This may be done by checking such animals for infection and killing and properly disposing of the bodies if the disease is discovered. Properly cooking meat and wearing protective clothing when handling meat may also be helpful, as are wearing protective clothing and washing handswhen around a person with the disease. Samples of bodily fluids and tissues from people with the disease should be handled with special caution. [ 1 ] No specific treatment for the disease is yet available. [ 1 ]Efforts to help those who are infected are supportive and include giving either oral rehydration therapy(slightly sweet and salty water to drink) or intravenous fluids. [ 1 ]The disease has a high risk of death, killing between 50% and 90% of those infected with the virus. [ 1 ] [ 3 ]EVD was first identified in Sudan(now South Sudan) and the Democratic Republic of the Congo. The disease typically occurs in outbreaks in tropical regions of sub-Saharan Africa.
