Publication:Dread Codex/New Spells/Greater Contagion

You can infect any living creature with a disease by simply touching it. This effect works like contagion, and the victim must make a Fortitude save or be infected with a disease of your choice, which strikes immediately with no incubation period. The main difference between this spell and contagion is that you have the potential to infect many more creatures because of the spell's duration (anyone you touch).

Material Component: A piece of putrid flesh and a drop of blood.
