Following the storm, the United Nations deployed field assessment teams to survey the damage caused by Katrina. The International Organization for Migration helped relocate affected families and construct at least 300 new residences for victims of Katrina and Hurricane Mitch the year prior. The Pan American Health Organization also deployed assessment teams to survey the area for the possibility of post-storm diseases. Due to the lack of any significant damage, the name "Katrina" was not retired and was re-used in the 2005 season; however, due to the catastrophic damage caused by the storm, it was retired in 2006 and was replaced with the name "Katia".
