What's the Name of That Book??? discussion

YA Dystopian/Post Apocalyptic Set in New York, The main character wakes up on a train in the subway with dead people all around him, but there are 3 other teenagers that are alive. He climbs up through the top of the train, and the city is in ruins, all the adults are infected with this disease that has basically turned them into zombies but they're all blue, then these teenagers travel to different parts of new york such as the central park zoo but when the main character passed the subway where he originally woke up he sees the dead bodies of his 3 friends that were supposedly with him before.
I've done lots of searching around and the only book I can find is The Enemy by Charlie Higson but I know it's not that because it was definitely set in NY and I'm pretty sure the cover was half the face of the blue zombie people, and then a kid running between two buildings.

Beat me to it by a few seconds!

Haha, sorry!

I don't think this is right, but it's close enough to mention as it starts on a subway train in New York and has zombies:
After the End
The survivors aren't just kids though (I don't think, from memory) and the zombies aren't blue.
