House M.D. Season 1 Episode 4

Two babies in separate delivery rooms delivered by separate staff become deathly ill within minutes of birth. Even though there's no way to explain how an infection could spread between them so quickly, the team must find some way to prevent an epidemic they can't yet identify. In chasing the killer, House must make a choice: give both babies the same treatment and loose both if he's wrong, or give them separate treatments to assure a positive ID of the illness, but also assuring that one of the babies will die.
