I've been having a bit of a horror-fest lately. Strangely, with a disease theme...
Carriers
By the numbers apocalyptic disease story about a group of 'teenagers' (according to the blurb - the youngest looks about 25
) looking for somewhere safe to set up home after most of the world's population are killed by a very contagious virus. Yawn.
Mutants
French movie about a virus that turns people into bloodthirsty monsters (think 28 Days Later but with subtitles). The story follows a doctor and her infected husband as they hide out, with hubby slowly undergoing the transformation into a 'mutant'. Not bad, but the subtitles kind of break the magic 
Doomsday
One of the worst films I've ever seen. Unbelievable tosh. It's about the 'Reaper Virus' (bad start when they show you bacteria multiplying...) that erupts in Scotland. The entire country is quarantined by the military with no-one going in, and no one coming out. Those inside are left to fend for themselves/die. Twenty-odd years later, the virus breaks out in London. A 'crack team' of military folk (including tough-bitch woman, token black man, and geeky scientist man) go into Scotland to find the doctor who had been working on the cure. Once in, they find the survivors have split into two camps - Mad Max style leather clad cannibals, and Lord of the Rings stylee 'we have been chosen' back to earth nutters. All in all, absolute drivel.
Next on the play list is Romero's original 'The Crazies'
