Forever!
Firstly order bottles of Eau du death as soon as you hear the news. Buy or book cruise before hand to use as a safe place or move to a safe house in mountainous region with stocks of packaged food to survive as long as possible while the armed forces and scientists try to combat the threat. When it is time to collect the supplies, Eau de death would help in camouflage the living human scent. Use the courage as the mask. Happy survival :)
