It happened right in the middle of a live broadcast. One minute, veteran journalist John Roberts is doing what he does best—anchoring America Reports—and the next, something is visibly wrong. Viewers started noticing a tremor. Then, it became more pronounced. By the time the segment wrapped, John Roberts shivering on air wasn't just a social media rumor; it was a medical emergency playing out in front of millions of people.
Honestly, it's the kind of thing that makes your heart sink. We see these anchors as indestructible figures of calm, but the reality behind the scenes was much more terrifying than a simple case of the "chills."

The Moment the Shivering Started
On Monday, August 25, 2025, Roberts was co-anchoring with Sandra Smith when his body basically revolted. He later described the sensation to PEOPLE magazine as hurting from "the top of my head to the tip of my toes." That's not just discomfort. That is a full-body shutdown.
While he was trying to deliver the news, he was hit with what doctors call "uncontrolled shivering." Initially, Roberts—being the pro that he is—tried to brush it off. He thought it was just muscle cramps or maybe the early stages of a nasty flu. He even managed to finish his show, which is honestly a testament to his grit, or maybe just how much adrenaline you get from being on live TV.
But as soon as the cameras cut, the situation spiraled.
He wasn't just cold. He was shaking like a leaf. His rheumatologist took one look at his blood work—which showed dangerously low levels of platelets and white blood cells—and sent him straight to the Emergency Room at Inova Health.
Why Malaria Caught Everyone Off Guard
You don't expect a news anchor in Washington, D.C., to come down with a tropical disease. That’s the shocker. After some intensive testing, the diagnosis came back: severe malaria.

It sounds like something out of a history book or a travel warning for remote jungles, but for Roberts, it was very real. He had recently returned from a two-week vacation in Indonesia. He didn't even remember getting bitten by a mosquito. That's the scary part about malaria; it can hitch a ride in your system and wait about ten days before it decides to ruin your life.
Roberts was treated with IV artesunate, which he described as the "big gun" of treatments. This isn't your standard over-the-counter pill. It’s the first-line defense for severe cases because malaria is a parasite that literally eats your red blood cells. Without that intervention, the "shivering" people saw on air could have been the prelude to something much more fatal.
The Timeline of the Illness
- Early August: Roberts spends two weeks in Indonesia.
- August 15: Returns home feeling fine.
- August 25: Experiences "uncontrolled shivering" during his live broadcast.
- August 25 (Night): Hospitalized at Inova Health.
- August 26-28: Battles "wild swings" in temperature, alternating between freezing and sweating.
Misconceptions About Malaria in the U.S.
When news broke about John Roberts shivering on air, the internet did what the internet does—it speculated. Some people thought it was a stroke; others guessed it was a heart issue (given his 2018 heart procedure). But the malaria diagnosis highlighted a massive blind spot in our collective health knowledge.
Most people think you can’t get malaria in the U.S. unless you’re in a swamp in the 1800s. Not true. The CDC tracks about 2,000 cases a year in the States. Almost all of them are "imported," meaning travelers bring them back from tropical climates. Roberts joked on X (formerly Twitter) that he was the only person in the hospital with the disease. His doctor even told him he was the first case he’d ever personally treated.
It's a weirdly lonely thing to be the only person in a modern American hospital fighting a parasitic mosquito-borne illness.
The Recovery Process
Recovery wasn't a straight line. Roberts mentioned that even after starting the "big gun" meds, he had "down days." One hour he’d be fine, the next he’d be back to that bone-rattling shivering.
Severe malaria isn't just a fever. It’s an assault on the blood. The fact that he was back on the air by early September is pretty remarkable. It shows how fast medical science can work when you catch things early, but it also serves as a massive warning for anyone traveling to Southeast Asia or Africa.
Lessons from the Anchor Desk
If there is a takeaway from the whole John Roberts shivering on air saga, it’s that you can’t ignore what your body is telling you. If you’ve traveled recently and you start shaking, don’t assume it’s the flu.
What to do if you're traveling to malaria-prone areas:
- Consult a travel clinic: Don't just wing it. Get the prophylactic pills (and actually take them).
- Use repellent: DEET is your friend, even if it smells like a chemical factory.
- Watch the "window": Malaria symptoms usually pop up 7 to 30 days after a bite. If you feel sick within a month of coming home, tell your doctor exactly where you went.
John Roberts is back in the anchor chair now, looking a lot more stable than he did that Monday in August. It was a close call that played out in real-time, proving that even under the bright lights of a news studio, nature can still throw a curveball that leaves you shaking.
Next Steps for Your Health:
If you are planning a trip to a tropical region, check the CDC's Yellow Book for current malaria risks. If you have returned from travel and experience sudden chills, fever, or unexplained muscle aches, seek medical attention immediately and specify your travel history to your healthcare provider, as standard flu tests will not detect a parasitic infection.
