Hand, Foot and Mouth Season: Making Your Child's Playroom and Toys Safe Again

Every parent dreads the rainy-season message in the class group chat: "The classroom will be closed for a week." What worries us even more is the virus that may already have followed our children home and settled into their favourite toys.

The week Mind's house went quiet

Mind is thirty-four, a freelance graphic designer who works from a two-storey detached house in a quiet estate in Pak Kret, Nonthaburi. She and her husband Ek have two children: Khao Hom, five, in her second year of kindergarten, and Khao Pun, two and a half, who stays home with his sixty-eight-year-old grandmother. The heart of the house is the downstairs playroom. It used to be the formal sitting room, but these days it belongs entirely to the kids: alphabet foam mats, a plastic ball pit, a fabric play tent, dozens of soft toys, a toy kitchen and a tub of chunky building blocks that Khao Pun still likes to chew.

Every Friday evening it also doubles as the neighbourhood playdate spot, with three or four children from nearby houses piling in. Mind loved that her home had become the warm, welcoming place everyone gathered.

Then, on a Tuesday morning in July, the class teacher posted in the parents' LINE group that two children had come down with hand, foot and mouth disease. By Wednesday it was five. On Thursday the school closed the class for deep cleaning. Mind's relief lasted exactly one day. On Friday morning Khao Hom woke up with a fever of 38.5, refused breakfast and said her throat hurt. When Mind looked in her mouth she saw small red sores with white centres on her tongue and inside her cheeks. By the afternoon, clear blisters had appeared on her palms and the soles of her feet.

The paediatrician confirmed hand, foot and mouth disease. Keep her home, separate her things, sponge her to bring the fever down, offer cold drinks and soft food. Then he added one sentence that kept Mind awake that night: "Watch the little one closely. Children under three catch it very easily, and the virus can linger on toys and floors."

That evening Mind stood in the playroom doorway and took it all in. The blocks Khao Hom had played with the day before. The bunny both children fought over at bedtime. Hundreds of balls in the pit the siblings had burrowed into together. The foam mats they sat on every afternoon to eat snacks. She knew instantly that wiping things one by one would never be enough. If Khao Pun caught it, a toddler could have a much harder time. And Grandma, worn out from helping, had started to complain of a sore throat too.

Three days later, the thing she feared most happened. Khao Pun spiked a fever and refused his milk.

Understanding HFMD, and why the playroom is ground zero

Hand, foot and mouth disease (HFMD) is caused by viruses from the enterovirus family. It is most common in young children, especially under five, and in Thailand cases tend to peak in the cool, damp rainy season. Typical symptoms include fever, sore throat, painful mouth ulcers and a rash or small blisters on the palms and soles, and sometimes on the bottom. Most children recover on their own within seven to ten days, but certain strains can occasionally cause serious complications affecting the nervous system or heart.

The virus spreads through saliva, nasal mucus, fluid from blisters and stool. A sick child coughs or sneezes, touches a toy with a damp hand, and another child picks up that toy and puts it straight in their mouth. The whole chain can happen in seconds. What surprises many parents is that children can keep shedding the virus in their stool for weeks after they feel better, and enteroviruses are fairly hardy in the environment, surviving on surfaces long enough to reach the next person.

That makes a playroom an almost perfect transmission zone. There are huge numbers of toys, many with complicated shapes and crevices: plush animals that soak up drool, fabric tents children crawl in and out of, foam mats with interlocking seams, and ball pits holding hundreds of balls. Small children put everything in their mouths and crawl across every surface, so their exposure is many times higher than an adult's.

Thailand's Department of Disease Control advises parents and schools to wash hands frequently, keep sick children apart, and regularly clean toys and surfaces children touch. The real question is how you clean thoroughly in a home with hundreds of toys.

There is one more gap parents rarely think about. When a kindergarten closes a classroom, the school deep-cleans its own rooms before children return. Nobody does the same for the playrooms, bedrooms and living rooms where those same children spend their evenings and weekends. If the virus came home in a backpack, on a water bottle or on little hands, the school clean does nothing for your house. That is why the week of a class closure is exactly the right moment to think about disinfecting at home too, so that when school reopens, your child is not bringing the virus back in the other direction.

What parents carry when the virus comes home

Your children's health, and everyone else's

Children with HFMD often have such painful mouths that they stop eating, and some refuse to drink, which puts them at risk of dehydration. Parents have to watch constantly for warning signs such as unusual drowsiness, vomiting, rapid breathing or jerky, trembling movements, any of which means going to hospital immediately. Toddlers like Khao Pun, whose immune systems are still developing, need especially close monitoring. Adults can catch it too. Symptoms are usually milder, but a grandparent providing hands-on care can easily end up exhausted and unwell.

Money that disappears overnight

There are doctor's fees, medicines and soothing mouth gels, and if a child becomes dehydrated and needs admission, the bill climbs quickly. For a freelancer like Mind, every day spent nursing a sick child is a day with no deliverables. She had to ask two clients for extensions and lost one project entirely. Ek took two days of leave. And the school fees already paid did not shrink just because the children missed weeks of class.

Relationships with neighbours and school

What stung Mind most was knowing her playroom was where half the estate's children spent Friday evenings. Once word got out that her kids were sick, some parents became noticeably hesitant about sending theirs over. Nobody said anything directly, but she could feel it. A year of goodwill wobbled in a single week.

Time and emotional energy

When children are ill, parents barely sleep. You are up sponging a fever, coaxing sips of water and comforting a child crying from mouth pain, and somewhere in between you are supposed to scrub hundreds of toys. Physical and emotional exhaustion piles up. Worst of all is the nagging uncertainty: have I cleaned enough? Will they catch it again?

Why ordinary cleaning falls short in a playroom

Mind did not sit still. From the first day, she tried every cleaning method she could think of, and the harder she worked, the more gaps she noticed.

Wiping toys one at a time. Large plastic toys are easy enough, but hundreds of small blocks, toy cars with wheels and grooves, and anything with moving parts inside simply cannot be wiped thoroughly. You can spend all night and still never know which piece you missed.

Washing soft toys and the play tent. Some plush toys have sound boxes or batteries sewn in and cannot go in water. Others are too big for the machine. A tent with a frame is awkward to wash and takes days to dry, and anything that does not dry completely soon smells musty and risks mold.

Reaching for strong disinfectants. Some products are effective against germs, but many parents worry about residue on toys their child will mouth an hour later. Harsh fumes set off coughing in children with allergies, and frequent use can fade or weaken some plastics.

Washing every ball in the ball pit. Hundreds of balls need soaking, rinsing and drying, which takes the better part of a day. The mesh and fabric pit itself still does not get properly cleaned.

Opening windows and running an air purifier. Good for ventilation, but neither one kills germs sitting on surfaces, toys and fabric, which is exactly where HFMD spreads.

Bagging everything up and waiting. Some families seal all the toys away for weeks. But some germs survive longer than people expect, and bored children get fractious, so the toys often come back out early.

Every one of these methods shares the same weakness: it depends on human effort and works one spot at a time, while the virus is spread across the whole room, on toys, in fabric, under mats, along skirting boards and on every piece of furniture little hands have touched. What Mind needed was a way to reach every surface at once without leaving chemicals behind for her children to touch.

One treatment that reaches every corner: WHD home ozone disinfection

Another mum in the parents' group, a nurse at a local hospital, told Mind about World Health Disinfection (WHD). The company disinfects for more than 300 organisations, including hospitals, schools, offices, factories and five-star hotels such as The Ritz-Carlton, Fraser Suites, Andaz and Dusit International. For Mind's situation, the right fit was WHD's residential ozone disinfection, a service built to treat an entire room in one go.

The service uses ozone gas (O3) generated by the Master Ozone Generator. Ozone is a strong oxidising agent. Released into a closed room, it drifts wherever air can travel: between building blocks, under toy car wheels, deep into the fur of soft toys, through tent fabric, between the balls in the pit, beneath foam mats and into the curtains. There it destroys pathogens at the molecular level. According to the service information, ozone eliminates viruses including SARS-CoV-2, kills more than 99.9% of bacteria, reduces mold and allergens and breaks down the stale smells that tend to build up in children's rooms.

What made the decision easy for Mind was this: ozone naturally reverts to oxygen (O2). There is no chemical residue left on the toys her toddler would be chewing the next day. And since the process is completely dry, talking plush toys, battery-powered toys, the sofa and any electronics in the room stay dry and undamaged.

The Master Ozone Generator has been certified and tested by Thailand's Department of Medical Sciences and by Intertek in the UK, and Intertek's testing found it ten times more effective than standard methods. For an exhausted mother who was done taking chances, that was reassurance she could actually point to.

How the roughly 30 minutes unfold

1. First 2 minutes: start-up and intensity setting. The technician checks the room and confirms that every child, adult, pet and plant has left, then switches the machine on and adjusts the level to the room size.
2. Next 12 minutes: distribution. Ozone fills the playroom, reaching every toy laid out on the floor as well as fabrics, rugs and hidden corners.
3. Following 12 minutes: purification. Ozone reacts with viruses, bacteria and fungi, breaking them down at the molecular level.
4. Final 4 minutes: system pause. The generator stops so the ozone can decompose. The technician then opens and ventilates the room before letting the family back in.

Safety first: no people, children, pets or plants may be in the room during treatment. The WHD technician stays in control of the machine throughout and only opens and ventilates the space after the pause. On the day, Mind took the kids and Grandma upstairs to a bedroom with the door closed, and the upstairs rooms were treated in a second round afterwards.

10 reasons parents choose ozone for the playroom during outbreak season

1. Hundreds of toys treated at once. No more midnight wiping sessions; just spread the toys out so air can reach them.
2. It gets into tiny gaps. Gas flows into block studs, robot joints and wheel arches no cloth can reach.
3. It handles soft toys you cannot wash. Talking teddies, crawling cushions and fabric tents get disinfected without a drop of water.
4. Nothing left behind for little mouths. Ozone becomes oxygen again, which matters in a home with a toddler.
5. The whole room, not just what you can see. Rugs, curtains, the underside of foam mats and every corner are included.
6. About half an hour per area. Parents get their time back to care for a sick child instead of scrubbing all night.
7. Stale air and allergens go too. Air-conditioned kids' rooms often trap mustiness, and ozone leaves the air noticeably fresher.
8. Certified equipment. The Master Ozone Generator has been tested by the Department of Medical Sciences and Intertek.
9. A team used to school and hospital standards. WHD has looked after hundreds of sites where hygiene truly matters.
10. Playdates with peace of mind. You can tell other parents, honestly, that the playroom has been professionally disinfected.

Khao Hom and Khao Pun's playroom: before and after

Mind, Pak Kret, in her own words

"Honestly, I was running on empty. My eldest had only just started eating again when the little one went down with it. At one point I was ready to throw out every toy and start over, but my daughter sobbed and would not let me bin her bunny. When I spoke to the WHD team, they explained exactly what to do: tip the toys out of their boxes, spread them around, open up the tent, pour out some of the balls and take everyone upstairs. It took about half an hour, and then the technician opened up the room and aired it out. When I walked back in there was no chemical smell at all, just a room that felt clean and light. We still washed the toys the kids put in their mouths, like the doctor suggested, for extra peace of mind. Once the doctor said both children were fully recovered, we opened the playroom to their friends again. I shared a few photos in the parents' group showing what we had done, and everyone felt reassured."

Important: ozone treatment disinfects the home environment. It does not replace medical care or handwashing. If your child has a high fever, is unusually drowsy, is vomiting or breathing fast, go to hospital straight away.

A rainy-season HFMD checklist for home

• Teach children to wash their hands with soap before meals, after using the toilet and as soon as they get home from school. Adults should wash up after every nappy change.
• Keep an eye on the parents' group and school notices. If a classmate falls ill, watch your child closely for the following week.
• If your child gets sick, give them their own toys, cup, spoon and towel, and keep them home for as long as the doctor advises.
• Rotate toys and keep the ones not in use in closed boxes, so there are fewer surfaces to look after at any one time.
• Wash toys your child regularly mouths in soapy water and let them dry completely.
• Plan an ozone treatment for the playroom and bedrooms once your child has recovered, before other children come to play or before a new term starts.
• Keep your nearest hospital's number handy and learn the warning signs that mean you should seek care urgently.

Questions parents often ask

Should we treat the room while our child is sick, or after they recover?
Either works. Many families treat the playroom straight away to protect siblings who have not caught it yet, then book a second treatment once everyone is well and before other children visit. Whichever you choose, everyone must be out of the treated area while ozone is running.

How should we prepare the toys?
Empty toy boxes and baskets, spread everything out with gaps in between, open the play tent and leave toy cupboards and drawers open so the gas can reach inside. The technician will give extra tips based on your room.

Will there be residue on toys my toddler puts in his mouth?
Ozone breaks down into oxygen, so it leaves no chemicals on toys. That said, washing mouthed toys in soapy water remains a good everyday habit worth keeping.

When can the children go back into the room?
Once the machine has stopped and the technician has opened and ventilated the room, they will let you know it is ready.

Does ozone treatment mean my child will never catch HFMD again?
No treatment can promise that. Ozone reduces germs in your home environment, but children can still pick up the virus at school or in public places. It works best alongside handwashing and good everyday hygiene.

Will it damage electronic toys or plush toys with sound boxes?
The process is dry and uses no water, so battery-powered toys and electronics will not get wet.

Can you treat just the playroom?
Yes. You can choose the playroom only, children's bedrooms or the whole house. Check details and pricing on the service page or message LINE @whd268.
