This PF cadre Hendrix Mutale asked me to share to the Public some essential information about ebola virus here is a brief info u may need my brothers and sisters, EVD is caused by four of five viruses classified in the genus Ebolavirus, family Filoviridae, order Mononegavirales. The four disease-causing viruses are Bundibugyo virus (BDBV), Sudan virus (SUDV), Taï Forest virus (TAFV), and one called simply, Ebola virus (EBOV, formerly Zaire Ebola virus)). Ebola virus is the sole member of the Zaire ebolavirus species, and the most dangerous of the known Ebola disease-causing viruses, as well as being responsible for the largest number of outbreaks.The fifth virus, Reston virus (RESTV), is not thought to be disease-causing in humans. The five Ebola viruses are closely related to the Marburg viruses. Transmission It is not entirely clear how Ebola is spread. EVD is believed to occur after an ebola virus is transmitted to an initial human by contact with an infected animals body fluids. Human-to-human transmission can occur via direct contact with blood or bodily fluids from an infected person (including embalming of an infected dead person) or by contact with contaminated medical equipment, particularly needles and syringes.The potential for widespread EVD infections is considered low as the disease is only spread by direct contact with the secretions from someone who is showing signs of infection. The quick onset of symptoms makes it easier to identify sick individuals and limits a persons ability to spread the disease by traveling. Because dead bodies are still infectious local traditional burial rituals may spread the disease. Semen may be infectious in survivors for up to 50 days. Medical workers who do not wear appropriate protective clothing may also contract the disease. In the past, hospital-acquired transmission has occurred in African hospitals due to the reuse of needles and lack of universal precautions. Airborne transmission has not been documented during EVD outbreaks.They are, however, infectious as breathable 0.8– to 1.2-μm laboratory-generated droplets.The virus has been shown to travel, without contact, from pigs to primates, although the same study failed to demonstrate similar transmission between non-human primates. Bats drop partially eaten fruits and pulp, then land mammals such as gorillas and duikers feed on these fallen fruits. This chain of events forms a possible indirect means of transmission from the natural host to animal populations, which has led to research towards viral shedding in the saliva of bats. Fruit production, animal behavior, and other factors vary at different times and places that may trigger outbreaks among animal populations. DR Jay Jay
