Those are secretions, but they are not derived from blood. The cells that secrete those liquids are not cells that the Ebola virus attacks. So, unless the secretions are bloody, they are not infectious.
I read one report where viral RNA was detected in bloody saliva (of one patient), but it was not infectious. The researchers thought that perhaps immune molecules in the saliva destroyed the virus.
In spite of the fact that one of the major symptoms is ‘bloody nose’.

Wrong, wrong, wrong. See “Assessment of the Risk of Ebola Virus Transmission from Bodily Fluids and Fomites” in the Journal of Infectious diseases at

Table 1, in which various fluids of ebola patients were tested:
breast milk 100% positive
saliva 67% positive
stool (acute) 50%
tears 100%
nasal blood 100%
semen 50%
...
Admittedly, the pool size of samples was very small (sometimes only 1 or 2 samples taken), but the evidence is clear...
