Hoffan plague

Overview
The Hoffan plague is a sickness afflicting Humans that is a result of a modified strain of the Hoffan drug. The drug was originally designed by the Hoffans as a means of combatting the Wraith. It effectively makes Humans immune to the Wraith feeding process by killing any Wraith that attempts to feed on them. Unfortunately, the drug also kills 30% of the affected Human population.

History
When the Wraith learned of this new threat, they laid waste to the planet Hoff.

But the research was stolen by Michael Kenmore, and with the help of a cloned Carson Beckett he refined the drug and distributed it through food and water supplies to dozens of Human planets, effectively beginning this plague. Any survivors of the plague are killed instead of culled by the Wraith. People are forced to flee their homes as the Wraith seek to destroy all traces of the drug, and resume their feeding indiscriminently.
