Guadalajara: Hand, Foot and Mouth Disease in Schools and the Prevention Question for Youth Football

Roughly six confirmed cases of Coxsackie virus have been reported at a school in the Oblatos district of Guadalajara, in the Mexican state of Jalisco. The number is small enough to slip past almost every major news bulletin of the day. But to me — someone who has spent years standing on the touchline of youth pitches — those six cases say something a torn ligament never could: that what stops youth football is rarely a reckless tackle, but often a hand that was not washed in time.

Coxsackie virus belongs to the enterovirus group and is a familiar cause of hand, foot and mouth disease. It presents with fever, mouth ulcers and small blisters on the palms and soles. It spreads mainly through direct contact with secretions, through droplets when coughing or sneezing, and through the faecal-oral route — in other words, through exactly what children do with one another every day: touching, holding hands, sharing a water bottle, sharing a towel. According to the Secretaría de Salud Jalisco (Jalisco State Health Secretariat), the state recorded around 120 cases in 2026, with the school cluster in Oblatos accounting for roughly six. Notably, no deaths have been reported, and health authorities assess the severity as low.

But what should make youth football pause lies in another detail. There is no specific antiviral treatment for hand, foot and mouth disease; care is symptomatic only. Health authorities also say prolonged isolation is not necessary. That very "mildness" is the trap. A young player with a slight fever and a few blisters on his palm can still take the pitch, still shake hands with teammates, still share the water bottle at the break. The virus does not need a tackle to spread. It only needs a dressing room.

I have thought a great deal about the silence of empty dressing rooms. After the 2026 pandemic, when stadiums became diaries written in dust, I learned that football does not exist only in the moment the ball rolls. It exists in invisible things: breath, sweat, a shared towel, the laughter of children before kick-off. And those same invisible things are the shortest path for a virus. Every hand that touches another hand in a dressing room is a whisper only the virus can hear.

Guadalajara is one of Mexico's greatest football cradles. The city is home to Club Deportivo Guadalajara — known across the country by the affectionate name Chivas — and to Atlas FC. Their two youth academies nurture hundreds of teenage players each year. Alongside them sits the school football system and grassroots competitions, where children in Jalisco play with a dense rhythm: school in the morning, technical training in the afternoon, matches at the weekend. It is an ideal environment for any infection that spreads through close contact.

Picture an ordinary training day. Thirty children in a cramped dressing room. One water bottle passed from hand to hand. Shared towels. Handshakes and hugs after every goal in a practice match. Substitute benches where a sick child still sits beside a friend for ninety minutes. In professional football, people measure distance covered, heart rate, blood lactate. But no one measures how many times one hand touches another. That is the biggest data gap in youth football, and it only becomes visible when an outbreak arrives.

The greatest blind spot in youth football is not injury, but infectious disease. We have built an entire industry around preventing anterior cruciate ligament tears, around conditioning drills, around the notion of "load management". We talk about fixture congestion as the culprit behind muscle injuries — and that is true. But when a child misses training because of a fever, we call it "just a cold" and move on. In reality, an outbreak inside an academy can wipe out a week of training, a week of fixtures and, worse, spread into the family of every child.

There is a telling comparison in the guidance from Jalisco health authorities. They place hand, foot and mouth disease alongside measles — a far more transmissible illness. The comparison is meant to reassure: Coxsackie is not as contagious as measles. But it also inadvertently points out that, inside a closed dressing room, the distance between "not very contagious" and "already transmitted" is one training session.

Let me be clear: I am not emphasising fear. Six cases in Oblatos, around 120 statewide, no deaths — this is not a catastrophe. It is a signal. And a signal must be read in time, before it becomes an alarm. Youth football in many places, including Asia and Vietnam, still has a habit of waiting: waiting for case numbers to rise, waiting for doctors to speak up, waiting for a star to be infected before anyone starts washing their hands. But a virus waits for no one.

In years of watching football, I have noticed a rule: what we cannot see is what decides. A goal-scoring pass usually begins in a space no one noticed. A collapsed season usually begins with a detail that was overlooked. And a child forced to miss a month of football sometimes begins with a tiny blister on the palm that no one looked at closely.

The solution, sadly, is very simple and very old: wash hands with soap, do not share water bottles, sanitise dressing rooms and equipment, lightly isolate symptomatic cases, monitor early and report transparently. This is not high technology. It is not expensive sports science. It is basic hygiene — something sometimes dismissed as trivial in a youth football culture busy chasing results.

In history, hand, foot and mouth outbreaks in schools are nothing new. They return with the seasons, with the cycles of weather and crowds. What is striking is that our reactions return in the same circle too: panic, then forgetting, then panic again. Perhaps football, with its cyclical nature — one season following another, one generation following the next — is the right place to break that loop, because here the memory of a child forced to miss training still lingers in the memory of empty seats.

In Vietnam, where I was born, and in China, where I work, youth football faces the same question: who is responsible when one child infects the whole team? The coach? The doctor? The parents? Or the child himself, for hiding a fever to get on the pitch? The answer lies not with an individual but with a process. And a process must be written before the outbreak arrives, not after it has passed.

I am not writing this to frighten anyone. I am writing it as a reminder that, amid arguments about tactics, transfers and who is better than whom, there remains a lower and more necessary layer of truth: the health of the children learning to play. When the stadium lights go out, what remains is not the scoreline. It is healthy children, fit enough to take the pitch again tomorrow.

Perhaps it is time for youth football academies to treat dressing-room hygiene and case management as a formal part of the curriculum, on a par with fitness and tactics. Because a great player of tomorrow must first be a child who is not sick tomorrow.
