Depends on the scale of the infection really and how fast the immune system generates antibodies. No disease is deadly with just a few pathogens but one of those bloated legged creatures... And if you've got some creatures with immune systems beyond anything found on earth they could defeat even fairly large incursions.
Besides, the whole point is irrelevant as most sci-fi armies use filters and armor. This also means that any civilians they get from other worlds won't be very effective against the intelligent troops in power armor.
I'd love to see the flood using mechas. They're ridiculously inefficient for their cost and the good guys can continue to use their "outmoded" tanks.
Your comment on mechas makes it fairly clear that you consider coolness the primary factor for determining the power of something. Right?
Note: A species whose method of attack is biological will never triumph on the battlefield against a technologically advanced species if the battlefield uses the laws of physics (or a close varient thereof) of our universe. And I'm not talking about quantum physics, I'm talking Newton.
I do not consider "coolness" When I think about power. Flood in Mecha would be kinda scary(Imagine seeing one of your own machines covered a fleshy mass with tendrils and all what not coming off of it while infection forms spew out of it's once familiar cockpit and all of it's remaining weaponry is unleashed upon you. I think you would shit brix the first few times), but I didn't say it would be the worst thing in the world. Also when you say "Oh well we have armor yay!" The flood do not use just bio/melee weaponry.
Flood on their own can
A) Wield weapons and operate machinery that their host could use/operate
Flood with a gravemind
B) Pretty much use damn most every thing, seeing as the gravemind has the collective knowledge of any organism the flood have infected.
The flood do not purely use biological warfare and can still prevail against armored units IE hmm the Master Chief in powered armor with shielding and he can still die to flood. (I do realize but this is game balance, but still the concept is the same powered armor!= win against the flood)
Also another point about powered armor, shielded armor: The elites had powered/shielded armor along with the brutes and they still were infected and they were a supposedly technologically advanced race.
The flood will fuck your shit up, plain and simple.

Flayer guns + living metal. Interesting to see what they could try against that.
Necrons I could see being a nice piece of competitoin against the flood, if the flood could find the heart of the Necrons (if I'm getting my lore right) and take out the production/self repair systems the flood could stand a chance.
It would be a very interesting fight to see though.
