Possible? its been done. The soviet/russian biopreparat HAS weaponized hybrid derivatives of ebola, mainly one with smallpox, creating a confluent haemorrhagic smallpox varient. Smallpox has likewise been fucked with in this manner, (note, its NOT a virus, but a spore-forming bacterium) to create an agent dubbed 'veepox', by splicing its genome with venezuelan equine encephalitis virus..
However, re the quote above, I was referring to the possibility that an airborne version of Marburg or Ebola might occure naturally, in the field, rather than in some Stephen King imagined novel or through some non-fictional release of material due to American stupidity. I'm quite aware that successful weaponsion of deadly bugs of various sorts have been worked on & may well have been completed in both the USA & in the old, & new, USSR.
Xenophobia? no. Not at all. But it would be a great idea to carpet bomb africa with mustard gas or VX and wipe the all the bloody foreign bastards out before any of the plague-ridden fuckers get over here (sorry, I had to)
Hahaha forgiven
