I remember seeing a ?Panorama report on USSR-era Russia using phages a lot instead of antibiotics from ?1960's-80's.
It's like using anteaters to get rid of ants, they'll not suddenly start eating cows, but the ants might burrow deeper, or come out at midday instead of morning.
Phages are a bit like putting a lion into a hen coop. they'll chew everything up & then hang around not bothered for a while.
I used to think bleach was pretty ultimate..until you get bacteria that hide in biofilms 'slime'. So high dose radiation? Denisococcus radiodurans [sp?], and a Bacillus. Sulphate reducing bacteria in superhot/acidic deepsea vents & colouful geysers on land.... 'extremophiles' are mad and hard as nails.
Ebola used to be like a phage in that it'd burn through humans quickly then recede as no (human) hosts left to get to in time.. encroachment on wild reservoirs, spread of bushmeat vs farmed mea? quite a range of pathogenicity, can spread further before people drop -
maybe it's time to treat it like TB used to be, kept in sanitoriums, enforced drug treatment (not 'half a course of antibiotics in the community and hydration/sedation').
I really liked The Hot Zone book and film'Outbreak'..except they had salmonellae in a virology dept...
