Ebola has once again resurfaced . On Friday , the World Health Organizationreportedthat there have been at least 34 suspected cases of the viral disease and 18 deaths since former April in the Bikoro District of the Democratic Republic of the Congo ( DRC ) . But Ebola ’s revitalization , hardly unexpected , ca n’t help but bring a question to mind : Why have n’t we find a surefire way to cure or prevent it yet ?
The short answer is that , for the majority of Ebola ’s know existence , government and pharmaceutic companies did n’t allocate the form of resources needed to find and educate treatments , both for practical and economic reason . But following the major outbreak of Ebola in 2014 , that trend is change .
Sufferers of Ebola initially grow a flu - like unwellness . Oftentimes , though , the computer virus tears through the resistant system with ease , causingit to corkscrew out of control and attack the torso in a desperate bid to kill the virus . Ebola also infects the cells that line our blood vessels and organs , hampering their power to properly clot , which avail touch off the revealing widespread hemorrhaging .
The first known outbreak of Ebolaoccurredin the DRC , then called Zaire , in 1976 . It was there that the disease , refer after a nearby river , became synonymous with death . It kill 280 of the 318 hoi polloi known to have been infected .
But while Ebola ( and its cousin the Marburg virus ) justifiably earn a frightening report over the next few decades , it never became the worst - slip scenario somejournalistsandHollywood screenwriterspumped it up to be — a pandemic killer that jumps from individual to person with repose . And that sputtering out made the prospect of get a cure or vaccinum much less of a anteriority .
man , for one , are n’t the main host of Ebola , though it ’s still a moment of mystery as to what is ( the wise money aright now is on yield bat ) . Whichever animal is the primary host , they only seem to live in choice part of West Africa and do n’t come into striking with people enough to constantly channelize the disease , dissimilar , say , mosquitos . Even once it infects people , Ebola ’s potential to spread picket in comparison to the influenza or even a distinctive stomach bug . Person - to - mortal transmission requires close , prolonged middleman with contaminated bodily fluids like profligate and semen .
Because of these factor , Ebola did n’t sicken that many multitude for the longest time . Prior to the outbreak of 2014 , it’sestimatedthat there were under 2,500 reported cases of Ebola worldwide . For context , malariakilledalmost a half million masses in 2016 alone . In some grammatical case , the deadliness of a exceptional Ebola striving kept outbreaks from having enough time to diffuse far ( there are five known type of the computer virus , one of which does n’t sicken mankind , and their human death rates range from 25 percent to 90 per centum ) .
Public wellness organizations like the Centers for Disease Control and Prevention and the WHO did devote time to studying viruses like Ebola , of course , especially given the potential for them to be weaponized as a biological terrorism menace . And researchers , often governing - funded , did seek to developexperimental treatmentsandvaccines , though these either failed or very lento move on . But pharmaceutical companies and even move governments did n’t think it was worth putting too much money toward finding a agency to battle something that was seen as more of a morbid curiosity than an urgent public health scourge .
A 2016study , for instance , feel that from 1997 to 2013 , a total of about $ 600 million ( in 2015 dollars ) was spend across the US and the Europe on Ebola and Marburg inquiry , primarily by government and nonprofit sources . That might sound like a lot , but the US spent over$500 billionon public and private R&D in 2015 alone .
There ’s some justification for this research lag . From 1979 to 1994 , for example , there were exactly zero cases of Ebola reported at all . But there ’s also the fact that outbreaks tended to happen among people living in isolated and impoverished sphere of Africa , produce it even less of an interest for profit - minded pharmaceutical company companies .
Of course , things changed in 2014 , when the largest outbreak of Ebola yet scorched through West Africa and even reached Dallas and New York City . By the time the outbreak wasdeclaredover in 2016 , there were intimately 30,000 suspected case of Ebola and 11,000 dying .
That outbreak set off a wafture of outsizedpanicin the US , as well asdiscriminationagainst people perceived to be African . As garbled as that reaction was , present the small threat vex by Ebola in America , it did lead to an discharge of resources into Ebola research across the US and elsewhere , peculiarly in essay to create a vaccine .
The experimental vaccine rVSV - ZEBOV was earlier developed by publicly funded Canadian researcher bulge out in 2003 . But by the fourth dimension the 2014 outbreak start spreading wide , it was in thehandsof biopharmaceutical company NewLink Genetics Corporation . It then sold the rights to Merck later that year . And in 2015 , Merck , work together with the WHO and other public health organisation , test rVSV - ZEBOV in over 5,000 people living in Guinea , where cases of the disease were still popping up .
By the terminal of 2016 , researchersreportedthat the vaccinum had on the face of it been a succeeder . No one who select the vaccine became disgusted 10 daylight or more after they make the shot , compared to 23 the great unwashed who went unvaccinated and became ill . There has been debate about whether the vaccinum is 100 percent effective , given early bailiwick that found a lower effectiveness , but a study publish in the Lancet this Aprilsuggestedthat the vaccinum provide at least two years of protection against infection .
The rVSV - ZEBOV vaccinum is still observational and only protects against the Ebola Zaire computer virus , though that is the most common character of Ebola in world and was creditworthy for the 2014 outbreak . Health officials have alreadydeployedthe vaccinum in little - graduated table outbreaks , and they ’re similarlyplanningto use it in the current eruption . There are also potentialantiviraltreatmentsfor Ebola in ontogeny , though it may take a long fourth dimension for any to become wide available even if they operate , since the typically modest number of cases in an eruption makes clinical inquiry hard to do .
Other pharmaceutical company are try out theirvaccinesin former clinical test , whileresearchers elsewhereare trying to find a mode to create a vaccinum that can protect against multiple , if not all , types of Ebola . And from 2014 to 2015 , upwards of $ 400 million in Ebola and Marburgresearchfunding was pass throughout the US and Europe .
As not bad as a unfailing treatment for Ebola would be , it ’s only part of what ’s need to keep the virus from causing hurt . Just as authoritative is a well - fund health upkeep infrastructure that can identify cases quick , prevent further transmission system , andprovidesomething as simple as discussion beds for the sick .
