Roberts described experiencing severe body pain, uncontrolled shivering, and dramatic
swings in temperature before doctors identified the mosquito-borne disease. “I have
never felt that sick in my life,” he said.
Early Symptoms Led to Hospitalization
John Roberts first noticed discomfort ranging from head-to-toe aches to intense chills
while hosting his program. At first, he suspected the flu. However, when symptoms
escalated, his rheumatologist advised him to seek immediate medical care.
Hospital tests revealed low platelet and white blood cell counts, leading to the malaria
diagnosis. “Malaria can be deadly if left unchecked,” Roberts said, acknowledging the
seriousness of the condition. He added with a touch of humor, “Of course, you have
malaria. You never do anything in small measures.”
Medical experts note that malaria symptoms often appear within weeks of being bitten
by an infected mosquito. Patients can experience cycles of chills, high fever, sweating,
and temporary relief before symptoms return. If untreated, the disease can progress
rapidly and, in severe cases, become life-threatening.
Treatment and Ongoing Recovery
John Roberts suspects he contracted the parasite while vacationing in Indonesia in July.
Symptoms appeared about ten days after his return to the United States. He is
currently being treated with intravenous artesunate, a medication used in severe
malaria cases.
Despite treatment, the anchor continues to experience alternating chills and fevers. “I’ll
be shivering and shaking like a leaf, and the next moment I’ll be sweating,” he explained.
Some days bring progress, while others remain difficult.
According to the Mayo Clinic, malaria is caused by parasites transmitted through the
bites of infected Anopheles mosquitoes. While preventable and treatable, it remains
one of the world’s most persistent infectious diseases. The Centers for Disease Control
and Prevention (CDC) estimates that around 2,000 cases are diagnosed in the United
States each year, nearly all linked to international travel.
