Fox News anchor John Roberts is recovering after being diagnosed with malaria, a serious illness caused by mosquito-borne parasites. In an interview with PEOPLE Magazine, the 68-year-old journalist described the frightening symptoms he experienced, including full-body aches, uncontrollable shivering, and severe fatigue during a live broadcast. Initially thinking it was the flu, Roberts became concerned when his bloodwork revealed low white blood cells and platelets.

Following his rheumatologist’s advice, Roberts went to the ER, where doctors diagnosed him with malaria. Though he tried to remain light-hearted, joking about his tendency for dramatic situations, Roberts admitted he was “a little scared” due to the disease’s potentially deadly consequences. “I have never felt that sick in my life,” he said, emphasizing the severity of his experience.

Roberts believes he contracted malaria while vacationing in Indonesia earlier in August. Despite not remembering a mosquito bite, symptoms emerged about 10 days after his return. Malaria is common in tropical regions and can cause fever, chills, muscle pain, and digestive issues. Left untreated, it can lead to serious complications or death.

During hospitalization, Roberts was treated with IV artesunate, the U.S. standard for severe malaria. He described ongoing symptoms like wild temperature swings, intense sweating, and deep fatigue. On August 27, he described it as a “down day,” reflecting the fluctuating and grueling recovery process. He is expected to return to work on September 2.

Roberts thanked colleague Trace Gallagher for filling in during his absence and acknowledged the care provided by Inova Health, noting that even his doctors had rarely encountered a malaria case. He shared his story publicly to raise awareness about the disease.

Dr. Jeffrey Horelick added personal insight, recalling his own life-threatening bout with Plasmodium falciparum, the deadliest strain of malaria, and offered his support to Roberts, wishing him a full and swift recovery.
