Quirot returned from her accident in late 1993 and won a silver medal in the Central America Games, behind the Surinam athlete Letitia Vriesde. Then in 1995, at the World Championships in Gothenburg, she became World champion for the first time ever, defeating Vriesde and Kelly Holmes, who were second and third respectively. To gain victory she used a strong finishing kick to move from 5th to 1st down the stretch, something that comes largely from her background of also being a long-time top 400 metre runner. Maria Mutola was heavily favored, having been on a 3-year unbeaten streak, but stepped on a lane marker in the semis, being disqualified. Mutola would be victorious in all head-to-head encounters between her and Ana over 800 metres this year, including the season-ending grand prix final where Mutola would place 1st to Quirot's 5th.
