Can you contribute to a list of movies involving a virus that threatens mankind?

Crysis 2. It has an engineered virus that slowly transforms humans into a mass of pustules, that then gets harvested by aliens.

12 Monkeys

I’m watching 12 Monkeys now.
I’ve already watched Contagion.

Resident Evil

The Andromeda Strain (not sure virus exactly)
Blindness
Perfect Sense
Outbreak
Carriers
The Happening
It Comes at Night
The Seventh Seal
Black Death

Zombie/monster viruses:
The Omega Man
The Last Man on Earth
Quarantine
Dawn of the Dead
28 Days Later
28 Weeks Later
I Am Legend
Resident Evil

@Zaku The Happening wasn’t a virus. Plants released an airborne chemical that fogged the human mind into suicide.

To add to @Zaku
The alpha incident
Cabin Fever
The crazies
It comes at night
World War Z

Let’s not forget The Stand. Captain Trips was one hell of a plague.

I think The Happening qualifies

The Crazies was good, but I think that was chemical instead of biological.

The Cassandra Crossing is another, at least in McGuffin form.

Rise of the Planet of the Apes…those who know, know!

This one.
