Macrovirus

The macrovirus is a Trekverse organism that injects or sprays host bodies with virus-laced slime. Infected individuals crank out more bugs until they die. Voyager's EMH developed a cure.

The HQ Plague
The League of Mary Sue Factories started an epidemic in HQ on March 12, HST, leading to a total quarantine. All Agents were issued with TARDISes, and the town in New Caledonia was designated as a general meeting point. Tragically, during the attack, Makes-Things was killed.
