In the year 2268, Hodin had his daughter, Odana, meet with Starfleet Captain James T. Kirk on a mock-up of his starship, the USS Enterprise. Once contact was established, Odana would then contract Vegan choriomeningitis using Kirk's blood, a disease which Kirk had been cured of, but which still remained in his bloodstream. Hodin then planned for the fatal disease to be spread amongst the inhabitants of Gideon in an attempt to reduce the population, as the Gideon people were immune to all diseases on their planet.
Sometime later, his council accepted the Federation's humane furnishment of phaser disposal units. This was to control the amount of dead corpses, as the overcrowded planet was unable to accommodate mass graves for disease-carrying bodies. However, Federation efforts to deploy methods of population control were squashed by Gideonite council members. (ST reference: The Worlds of the Federation)
