A Commonwealth Games athlete is in serious condition at a Gold Coast hospital after being diagnosed with malaria, officials said on Friday. The 23-year-old, who has not been identified, is under close observation at Gold Coast University Hospital, after being admitted on Thursday with the mosquito-borne disease.

“The patient received immediate treatment for malaria on arrival at GCUH. The patient remains admitted to GCUH in a serious condition and continues to be closely monitored,” a statement from the organising committee said. The statement added that “there is no locally acquired malaria in mainland Australia”.
