Should we spend some resources on Ebola? Of course. But those resources should be spent in line with the risks as we best understand them. By 2004 we already had evidence that coronaviruses were much more dangerous than Ebola, with the 2003/2004 SARS outbreak killing half as many people (774) as Ebola has in nearly 50 years. Ignoring COVID-19, SARS and MERS (both coronaviruses) have killed 1,640 people, exceeding Ebola’s grim toll.
It might be small _because_ we freak out about it. Kind of like New Zealand's COVID-19 numbers (or other countries with aggressive prevention / mitigation methods).
In comparing diseases we probably want to compare their transmission and mortality rates and long-term effects. If we compare their infection or death count then we're comparing the disease + the response together which muddies the waters a bit.
SARS was a huge sign that something like SARS-CoV-2 (coronavirus) was a significant risk. But, give it 10 years and I suspect research funding will once again be scarce until the next outbreak. It’s not about this disease so much as a reasonable response to a range of diseases like Ebola which easily and frequently make the jump to humans.
