Olympic Champion McKeown Out of Commonwealth Games with Mononucleosis
Australian swimming sensation Kaylee McKeown has withdrawn from the Commonwealth Games due to infectious mononucleosis, forcing her to miss the defense of her four titles and shift focus to recovery and future events.


Olympic and world champion Kaylee McKeown will not participate in the upcoming Commonwealth Games due to a diagnosis of infectious mononucleosis. The Australian swimmer, a dominant force in backstroke events, has been forced to withdraw from the competition, where she was expected to defend four of her titles.
The decision comes after a period of illness that has significantly impacted her training and performance. McKeown has experienced symptoms including fatigue, breathing difficulties, and a loss of appetite, leading her to prioritize her health and recovery.
“It has been a difficult decision, but it is the right one,” McKeown stated regarding her withdrawal. She indicated that she had not fully recovered during recent Australian trials and expressed concerns about overexerting her body, which could lead to prolonged chronic fatigue.
Focus on Long-Term Goals
With the Commonwealth Games now out of reach, McKeown’s attention will turn towards her recovery and preparation for the Paris Olympic Games. This strategic withdrawal is viewed as a crucial step to ensure she can compete at her peak in major international events. The Commonwealth Games were scheduled to run from July 23 to August 2.
A Star on the World Stage
McKeown is a highly decorated athlete in the swimming world. She holds world records in the 50m backstroke (26.86 seconds) and the 200m backstroke (2:03.14). Her absence from the Commonwealth Games will undoubtedly leave a noticeable gap in the swimming program, particularly in the backstroke disciplines.
