The history of Ebola and Ebola virus disease is different, both in impact and response. Ebola is vicious; out of 3,453 cases confirmed since the beginning of the current outbreak, 2264, or 66%, have died, similar to ratios from previous outbreaks and among the highest case fatality rates of any human pathogen .
First isolated in 1976 following separate ebola outbreaks in Sudan and what was then Zaire, there have been numerous outbreaks of Ebola since both small and large. However, scientific and media attention was limited for the first 20 years. An average of just nine yearly publications related to the Ebola virus were published between 1977-1994. In 1995, when a major Ebola outbreak occurred in DRC, interest began to be generated .
Coincidentally, the movie ‘Outbreak,’ released just two months before the first cases in the DRC, also increased public awareness of the Ebola virus. It was the 2014-6 epidemic, however, which displayed the epidemic potential of the disease, with nearly 30000 suspected cases and more than 11000 fatalities . The declaration of a PHEIC and a global response followed, including the use of experimental antiviral treatment and vaccination. Nevertheless, it took two years before the epidemic terminated.
It may well be an inconvenient truth that the responsiveness to any outbreak will be based on the impact on Western society, chiefly the economy, rather than the severity of the illness and endangerment to human life and well-being. Notwithstanding the vast amount of funds the global economy generates for medical research and treatment products, a more consistent global approach to tackling both the outbreaks themselves and managing awareness and attention would give less developed countries a better platform to address the events in a timely manner, minimizing the risk of extreme outcomes.
Thankfully the current outbreak has been less explosive than that of 2014-6, which could explain, if not forgive, the correspondingly tepid response; while organizations such as Médecins Sans Frontières (MSF, Doctors Without Borders) have been on the front lines from the beginning, it took the WHO four reviews of its original negative decision before they announced a PHEIC.
Unfortunately, the situation has been complicated considerably by an ongoing conflict, which has escalated to actively target healthcare workers, including 386 attacks, with 77 injured and seven dead in 2019 . Nevertheless, work has continued and has borne fruit, and new cases of Ebola have declined significantly during the current outbreak since the end of September 2019, with only one newly-confirmed case this past week, and hopefully, an end is close .
Outside of any political or economic reason, it is perhaps human nature to be attracted and fascinated by that which is new and shrouded in mystery and misinformation, and it is seemingly appropriate that the word “novel” (from Latin Novus, “new” or “fresh”) has been incorporated into the name of the virus which now makes the headlines.
All the same, the fact that a public health emergency is currently of less international import or concern does not make it any less important or pressing, especially to the locals and healthcare workers fighting the illness. Given the WHO saw fit to label it as such an emergency, it should also see fit to continue rendering assistance proportionate to that description until the emergency is completely over and the region free from further risk; otherwise, why have such labels at all?
