In a gut-wrenching update that’s left fans around the world in tears, beloved Dancing with the Stars judge and champion Derek Hough has revealed that his and wife Hayley Erbert‘s newborn baby has tested positive for whooping cough — the highly contagious and potentially dangerous respiratory infection also known as pertussis.

The 40-year-old dance icon, who shares daughter Elle Hough (born December 2024) with his wife of two years Hayley, 30, took to Instagram late on January 19, 2026, to share the devastating news in a raw and emotional post that has since gone viral.

“Hayley and I are heartbroken to share that our little Elle has tested positive for whooping cough,” Derek wrote alongside a black-and-white photo of the couple cradling their baby girl in hospital. “She’s so tiny, so fragile, and seeing her struggle breaks our hearts in ways we never imagined. We’re doing everything we can, and the doctors are incredible, but this virus is no joke. Please keep our baby girl in your thoughts and prayers.”

The announcement comes just weeks after the couple welcomed their first child — a moment they described as “pure magic” after years of fertility struggles, IVF journeys, and public openness about their path to parenthood. Now, what should have been the happiest chapter of their lives has been overshadowed by fear, hospital visits, and the relentless cough that defines the illness.

The Post That Broke Hearts Worldwide

Derek’s caption continued with unflinching honesty: “Whooping cough in newborns is terrifying. Her immune system is still developing, and the coughing fits are exhausting her little body. We’ve been isolating, masking, and following every protocol, but somehow it got through. Hayley and I are devastated — we feel like we failed to protect her — but we’re fighting right alongside her.”

He included a short video clip (muted for privacy) showing Elle in an incubator, tiny monitors beeping softly, with Derek’s hand gently resting on her chest. The image of the Mirrorball Trophy-winning dancer — usually so full of energy and joy — looking visibly shaken and tearful sent shockwaves through his millions of followers.

Within hours, the post racked up over 2 million likes and thousands of comments. Fellow celebrities, fans, and parents who’ve battled similar illnesses flooded the section with love and support.

A Relatable Nightmare for New Parents

Whooping cough, caused by the bacterium Bordetella pertussis, begins like a common cold but progresses to severe, uncontrollable coughing fits that can last for weeks — or in infants, lead to complications like pneumonia, seizures, brain damage, or even death. Newborns under six months are especially vulnerable because they haven’t yet completed the full DTaP vaccination series (the first dose is typically given at two months).

Health experts stress that maternal vaccination during pregnancy (the Tdap shot) and cocooning (ensuring close contacts are vaccinated) are the best protections — yet breakthrough cases still occur, especially in areas with declining vaccination rates or exposure to asymptomatic carriers.

Derek and Hayley have been open about their commitment to science-based parenting, including vaccinations, but the virus’s highly contagious nature means it can spread before symptoms appear. Sources close to the couple say they believe Elle may have been exposed during a family gathering or routine outing in the weeks leading up to her symptoms.

From Joy to Fear: The Hough-Erbert Journey to Parenthood

Derek and Hayley announced Elle’s birth on December 18, 2024, sharing dreamy black-and-white photos and the caption: “Our greatest adventure begins. Welcome to the world, Elle Hough.” The couple had endured years of heartbreak — Hayley suffered a life-threatening brain bleed after a 2023 dance tour injury, Derek supported her through recovery, and they navigated fertility challenges before conceiving via IVF.

Elle’s arrival was celebrated as a triumph of love and resilience. Derek frequently posted tender moments: Hayley breastfeeding, family cuddles, and his own emotional reflections on fatherhood. “She’s changed everything,” he wrote just days before the diagnosis.

Now, those same fans who rejoiced are rallying around the family in crisis.

Celebrity Friends and Fans Rally: ‘Sending All Our Love’

The response has been overwhelming:

• Julianne Hough (Derek’s sister): “My heart is shattered for you both. Elle is so strong — she’s got the best parents fighting for her. Love you endlessly.”
• Mark Ballas (former DWTS pro): “Brother, this is brutal. Praying hard for little Elle. You’ve got an army behind you.”
• Alfonso Ribeiro: “Derek and Hayley — hold tight. Elle is in the best hands. Sending healing energy to your family.”

Fans shared personal stories: “My son had whooping cough at 3 months — it’s terrifying but he pulled through. Stay strong!” Others urged vaccinations: “This is why we vaccinate. Praying for baby Elle.”

Many pointed out the cruel irony: Derek, who has spent his career lifting people up through dance and positivity, now faces one of life’s darkest challenges.

What Happens Next: Hospital Vigil and Hope

Derek updated followers the following morning (January 20, 2026): “Elle had a rough night with coughing fits, but she’s stable and the doctors are monitoring her oxygen levels closely. Hayley hasn’t left her side. Thank you for the love — it’s carrying us through.”

Medical sources say newborns with pertussis are typically hospitalized for observation, given antibiotics, and supported with oxygen or breathing assistance if needed. Recovery can take weeks, but with prompt care, most infants pull through.

Derek has paused public appearances and social media promotion of his upcoming projects (including a new dance tour and potential DWTS judging return) to focus entirely on his family. Hayley, a former DWTS troupe member turned wellness advocate, has gone silent online except for reposting Derek’s updates.

The Bigger Picture: A Wake-Up Call on Infant Health

The news has reignited conversations about whooping cough resurgence. Cases have risen in recent years due to vaccine hesitancy, waning immunity, and post-pandemic social mixing. The CDC reports thousands of cases annually in the U.S., with infants under one year at highest risk.

Health advocates are using the Houghs’ story to urge pregnant women and close contacts to get the Tdap booster. “Derek and Hayley’s pain is every parent’s nightmare,” one paediatrician posted. “This is preventable — let’s protect the tiniest among us.”

Derek Hough: From Ballroom King to Devoted Dad

Derek Hough is no stranger to public vulnerability. He’s shared his battles with anxiety, his sister’s health scares, and Hayley’s near-fatal bleed. But fatherhood has softened him in new ways — his Instagram filled with lullabies, baby giggles, and quiet moments of awe.

Now, that same openness is helping him through the darkest days. “We’re scared, we’re tired, but we’re not alone,” he wrote. “Elle is fighting like a warrior — just like her mum.”

As the couple keeps vigil in the hospital, the world watches, prays, and sends love. For a family that’s given so much joy through dance and inspiration, the least we can do is hold space for their pain.

Elle Hough, tiny but mighty, is fighting. And her parents — and millions of fans — are right there with her.

Get well soon, little one. The Hough family has carried us through tough times — now it’s our turn to carry them.
