Municipal Childcare Centre, 68 Children, Closed for Ten Days: Parents Across the Village Had to Stop Working
Why closing a childcare centre for ten days becomes an economic problem for the whole community, not just a problem for the centre.
A childcare centre is a room where sixty-eight children aged two to five nap side by side on the floor of the same hall, share the same toys, and where not one person can realistically wear a mask. This is what happened at a municipal centre in Nakhon Pathom, and how the effects spread across an entire village.
A childcare centre has a character no other setting shares. Children aged two to five cannot realistically wear masks, cannot realistically distance, and put their hands in their mouths constantly. That is not a discipline problem; it is normal development.
The staff work harder and more carefully than outsiders assume: toys washed every evening, floors cleaned, bedding laundered, hands washed before every meal. All correct, and all surface work — while the activity hall where sixty-eight children nap side by side for two hours a day has never had its air managed at all.
What follows is the whole story: the first day, the ten-day closure and its effect on parents across the village, and the change that stopped it. At the centre of it is the AIROFOG U260 ULV cold fogger, a German-engineered machine producing 15-30 micron droplets.
The nap hall shared by 68 children
Teacher Amporn heads a municipal childcare centre in Nakhon Pathom. It takes sixty-eight children aged two to five, with six childcare staff and one cook.
The building is single-storey with one large activity hall used for lessons, meals and the afternoon nap. Every child sleeps on a mat on the floor of that same hall for two hours a day, with the air conditioning on and the doors shut to keep mosquitoes out.
That month one child came in with a runny nose, which in this age group is so ordinary that nobody thought anything of it. The parents had to work and had nobody at home to mind the child.
That evening the staff washed every toy with disinfectant, cleaned the floor, folded the mats, switched off the air conditioning and locked up. The hall then sat sealed until seven the next morning.
Nine days: 31 children and 4 staff
Day three: five children absent. Day five: fourteen. Day seven: twenty-three. Day nine: thirty-one of sixty-eight.
The staff were hit harder, because they carry the children, feed them, wipe their noses and supervise the nap in that hall. Four of the six fell ill in the same week.
With two staff left to look after the thirty-seven children who were still well, the staff-to-child ratio fell clearly below the required standard. The centre had no choice but to close.
The municipality closed it for ten days for a deep clean and to let the staff recover. It was the right decision in the circumstances, and it left sixty-eight families to find their own solution overnight.
Ten days that hit the whole village
Most parents at a municipal centre are daily-wage workers: factory workers, farmers, casual labourers and market traders. For them, one day off is one day of income genuinely gone.
On later enquiry, about forty families had someone take at least five days off during those ten days. Another twenty left their children with grandparents, a group at far higher risk than the children themselves. Eight more had to take their children to work with them.
At a minimum wage of just 350 baht a day, forty families losing five days each is roughly 70,000 baht taken out of the community — before medical costs and travel.
Teacher Amporn says the hardest part was not closing. It was parents coming to plead with her to reopen, because they genuinely had no alternative, and she could not reopen because she did not have enough staff.
What the sub-district health centre suggested
After the centre reopened, an officer from the sub-district health promoting hospital visited and made one observation that changed how the centre thought about the problem.
She pointed out that the centre managed toy washing and handwashing very well, which addresses the contact route — but had nothing at all addressing the air route, in a hall where sixty-eight children breathe together for two hours every day with the doors shut and the air conditioning on.
She explained that the community hospital used a ULV fogger on its consultation and waiting rooms as routine work, and suggested the childcare centre could apply the same principle: fog in the evening after the children leave and again in the morning before they arrive.
What the centre needed was a machine the staff could operate themselves, at a price the municipality could approve within an ordinary budget line, that would not harm the toys or bedding, and that would reach the ceiling and air vents nobody had ever climbed up to clean.
The real impact, point by point
Small children genuinely cannot mask or distance
A two- to five-year-old pulls a mask off within minutes, puts hands in mouth, and moves towards other children constantly. That is normal development, not something teaching or enforcement can solve.
Closing the centre cuts income across the whole community
Most parents at a municipal centre are daily-wage workers. A ten-day closure is not an inconvenience; it is roughly 70,000 baht of income genuinely lost from one community.
Childcare staff are the most exposed and the least replaceable
Staff carry, feed, wipe noses and supervise naps, so they are closest for longest. With four of six ill, the staff-to-child ratio fell below standard immediately and the centre had to close.
Children sent to grandparents create the next risk
When the centre closes, many families leave children with elderly relatives — a group at far higher risk than the children. Closing the centre moves the risk onto the people least able to absorb it.
Why the usual approach is not enough
Washing toys with disinfectant every evening
Toy washing is done seriously by staff and genuinely works on the contact route. It does nothing about the air in a hall where sixty-eight children breathed together for two hours.
Washing children's hands before meals and after play
Handwashing is one of the most correct measures for small children and should continue. But it addresses the contact route, not the air route — they are different pathways.
Morning temperature screening
A morning temperature check catches only children who already have a fever. It misses those just starting, or with only a runny nose — which in this age group is so common it cannot be used as a screening criterion.
Opening doors and windows during nap time
The centre cannot leave doors open while children sleep: mosquitoes, insects and child safety. The heat would also stop the children sleeping, which disrupts the centre's whole daily schedule.
Closing for a deep clean after the outbreak
A ten-day closure for a deep clean makes the centre spotless on the day it happens, and the first week back puts everything in place again. Its real cost is not the disinfectant — it is the income of an entire community.
What the nap hall actually needs
The requirement is not washing toys more often. It is a treatment aimed at the volume of air in the activity hall, that takes minutes, and that runs every day in the evening after the children go home and in the morning before they arrive.
That is exactly what ULV cold fogging is designed for. ULV, ultra-low volume, means the machine breaks disinfectant into droplets fine enough that the output behaves more like fog than spray. The mist stays airborne long enough to fill the room, then settles evenly on every surface, including the ceiling, the vents, and the large toys that cannot be carried away to be washed.
The machine Teacher Amporn's centre chose is the AIROFOG U260: a German-engineered ULV cold fogger with an 800-watt motor and an adjustable nozzle producing 15-30 micron droplets, running on water plus the disinfectant the centre selects.
10 reasons to choose the AIROFOG U260 from World Health Disinfection
1. 15-30 micron droplets treat the whole activity hall
A hall used for lessons, meals and naps has more surface than anyone can wipe daily. Droplets in this range fill the room's volume and settle across every surface, including the ceiling and vents, in one pass.
2. It reaches large toys that cannot be carried away to wash
Ball pits, large plastic play equipment, shelving and the reading corner cannot be washed daily. Fogging covers all of them along with the whole room in a single pass.
3. It runs in the evening after the children go home
The hall takes only a few minutes to fog, then stays closed overnight — a window when it is already empty for fourteen hours. Not one minute of the centre's schedule is affected.
4. An 800-watt motor covers the whole building
One machine serves the activity hall, the children's bathrooms, the dining area and the staff room. The centre does not need several units, which matters greatly for a municipal budget.
5. The adjustable nozzle is safe around bedding and toys
Sleeping mats, blankets and soft toys must not be left damp. A drier nozzle setting means everything is dry and ready by the next morning.
6. It runs on a disinfectant chosen as suitable for a children's setting
The U260 is a delivery system, not a chemical lock-in. The centre can pick a low-odour product appropriate for a space used by small children, and we work out the correct dilution.
7. Staff can run it themselves, without waiting for a contracted budget
No waiting for the municipality to hire a contractor for the occasional visit, which usually means a few times a year. Staff can fill and fog every day, and learn it in an afternoon.
8. The daily cost is very low against the cost of closing
The consumables are water and disinfectant. For a centre this size the daily cost sits comfortably inside an annual materials budget, while a ten-day closure costs the community tens of thousands of baht.
9. It is the same class of equipment hospitals use
The U260 was designed for COVID-19 disinfection and is used in hospital and laboratory settings. For a centre reporting to the municipality and answering parents, that provenance is a clear answer.
10. It lets parents see what the centre is doing
A centre that fogs daily can post the schedule at the entrance and share photos in the parents' group chat, which builds far more community confidence than quietly washing toys where nobody sees it.
Before and after
Before
- Cleaning limited to toys, floors, bedding and children's handwashing
- The activity hall's ceiling and air vents never disinfected
- 68 children napping together in a sealed hall for two hours a day with no air management
- 31 children and 4 of 6 staff ill within nine days
- Centre closed for 10 days; around 40 families had someone off work for at least 5 days
- Roughly 70,000 baht of income lost from the community, and 20 children placed with elderly relatives
After
- ULV fogging of the activity hall every evening after the children leave and every morning before they arrive
- Coverage of the ceiling, vents, large toys, shelving and the reading corner
- Bedding and soft toys dry and ready by the next morning
- No further closure across the following school year
- Staff no longer falling ill together; the staff-to-child ratio stayed within standard throughout
- The fogging schedule posted at the entrance and reported daily in the parents' group chat
Three-step use
1. Look at the actual building, not just the number of children
Activity hall size and ceiling height, how many air conditioning units and where, how much large play equipment and bedding there is, the children's bathrooms and dining area, and when the building is genuinely empty. Those five things decide the route and the timing. Send us the floor plan or a short video.
2. Install the machine and train the childcare staff
We deliver the U260 with the nozzle set dry enough for a room with bedding and soft toys, the correct dilution for the product the centre selects, and a route mapped to your building. Training the staff takes an afternoon, and we prepare documentation you can use for the municipal purchasing process.
3. Fit it into the evening closing routine you already have
The routine that works is boring and repeatable: fog every evening after the children go home, and add a morning pass during a local outbreak. Once it sits inside the existing toy-washing step, it becomes simply what the centre does.
We washed the toys every day and washed the children's hands before every meal — the staff always did everything properly. But the hall where sixty-eight children breathe together for two hours a day, we had never done anything about the air in it. When we had to close for ten days, parents came and pleaded with us to reopen because they genuinely had nobody to mind their children. Now we fog every evening before we leave, and we have not had to close once this school year.

Why closing a childcare centre costs more than any budget line shows
When a secondary school closes, students can stay home alone. When an office closes, staff can work from home. When a childcare centre closes, one adult must genuinely stop working to look after one child, because a two- to five-year-old cannot be left alone for a minute.
In a community where most parents are daily-wage workers that multiplier is severe. Closing one centre for ten days means dozens of adults losing income simultaneously, in the same community, in the same week.
The alternatives families fall back on create further risk. Children left with grandparents put the highest-risk group in close contact with children who have just come out of an outbreak. Children taken to a parent's workplace end up somewhere not designed for them.
This is why prevention at a childcare centre has an economic value far above what the centre's materials budget suggests. What you are really protecting is not the cleaning cost — it is the income of a whole community.
What 15 to 30 microns actually means in practice
Droplet size is the specification that decides whether a machine solves this problem or merely makes things wet. Below roughly 10 microns, droplets are so light they can drift away before doing useful work. Above about 50 microns they behave like spray: they fall fast, and they leave sleeping mats and soft toys damp.
The 15-30 micron band is the working range. Droplets stay airborne long enough to fill the activity hall's volume and reach the ceiling and vents, then settle as a thin, even, fast-drying film. Bedding is dry and ready by the next morning.
It is also why an adjustable nozzle matters more than tank size. A hall with bedding and soft toys needs a drier setting than a tiled children's bathroom. Adjusting the nozzle gets you both from one machine.
For a childcare centre the practical test is simple: the next morning the mats should not feel damp to the touch, the plastic toys should be completely dry, and the ceiling corner above where the children sleep should genuinely have been treated.
Frequently asked questions
Is it safe around small children?
Fogging is done only when no children are in the building — after they go home or before they arrive — with a waiting period afterwards depending on the solution used. We recommend low-odour products suitable for spaces used by small children.
Will mats, blankets and soft toys be left damp?
No, with the nozzle set dry enough. ULV cold fogging at 15-30 microns leaves a very thin film that dries by itself within minutes. We configure it for a room with bedding at installation.
How long does the activity hall take?
Only a few minutes to fog, plus a closed-room period — and if you fog in the evening, that can simply be overnight. It does not affect the centre's schedule at all.
Can the childcare staff run it themselves?
Yes. Fill, set the nozzle, walk the route, close the door. We train them at handover — it takes an afternoon — with no waiting for an occasional contractor visit.
What disinfectant works with the U260?
The machine runs on water plus the solution you choose. It is not tied to one brand. We recommend products suitable for small children's spaces and work out the correct dilution.
Can a municipality purchase it through its normal budget?
We provide complete machine specifications and product documentation for the procurement process. Many centres purchase through their municipality's annual materials or equipment budget.
How often should a childcare centre fog?
Every evening after the children go home as standard, with an additional morning pass before they arrive during a local outbreak. Consistency matters far more than intensity.
Can it be used on the children's bathrooms and dining area too?
Yes, one machine covers the whole building. The bathrooms and dining area should be in every fogging round.
Prevention at a childcare centre protects the income of a whole community
Teacher Amporn's centre closed for ten days, costing about forty families at least five days of income each — roughly 70,000 baht out of the community — and placing twenty children with elderly relatives at higher risk.
A daily ULV fogging routine costs a sum an ordinary municipal materials budget can carry, and runs when the building is already empty. It covers the whole hall including the ceiling and vents, and it keeps the centre open.
If you run a childcare centre, a kindergarten, a nursery or any setting caring for small children, send us the floor plan and we will tell you exactly what it needs, with documentation for procurement.
