Question
Is there a stomach bug going around right now? Half my kid's class is out and I want to know what to watch for. Real household: caregiver juggling school week and one elder or sibling nearby. Schedule: Wed; after school. Kitchen/home right now: handwashing with soap and water. Already tried: relying only on hand sanitizer. Please answer as a practical family-care guide: what to do next tonight/today, what to avoid, and a clear decision tree. Constraints: respect «No diagnosis, no medication changes»; no dosing kids/pets/elders yourself; no mystery powders or buying prescription meds online; keep steps screenshot-friendly under ~25 minutes where cooking/care applies. Structure your help as (1) what I already tried vs better alternatives, (2) constraints/avoid list, (3) red flags—when to stop DIY and get clinical/urgent help. Keep the voice concrete and kind for a tired caregiver; stay inside kitchen/home-care/communication levers only. Name what success looks like in 24 hours without promising cures. Avoid brand shopping lists; focus on routines, food already at home, and communication scripts caregivers can screenshot.
Answer
Keep your child home from school for now and care for them at home tonight: soap-and-water handwashing (not sanitizer alone), small amounts of already-prepared oral rehydration solution if they're losing fluid, and the usual food they can tolerate.
Half the class being out is a meaningful hint that many children shared an exposure — vomiting-and-diarrhoea bugs do spread easily in schools and day care — but it does not tell you which germ it is, and I could not confirm a reported outbreak at your child's school from Thai public-health notices. So treat it as "something is going round, cause unknown" and run the plan below. This is a home-care guide, not a diagnosis.
If your child has no symptoms at all right now: you don't need to panic. Do the hygiene half of this plan, learn the signs below so you recognise them early, and if you can, keep them home for a couple of days while so many classmates are out.
1) What you've already tried → what to do instead
| You've done | Better next step |
|---|---|
| Relied on hand sanitizer as the main clean | Soap and water, 20 seconds, at the key moments: after the toilet, after nappy changes, before preparing food, before eating, after caring for a sick person. Sanitizer is a top-up, not a stand-in — the viruses behind vomiting-and-diarrhoea outbreaks are not reliably killed by it. |
| Soap and water already in the kitchen | Keep it, and add the timing plus surfaces: toilet, taps, door handles and light switches get wiped, and hands get washed the moment your child is home from school. |
| Waited and watched for signs | Instead of vague watching, use the decision tree below, and write down the times as you go. Written down, they tell you whether you are still in home care or need to move up. |
| Pulled back on food | Keep their usual meals and normal feeds. Don't stop food to "rest the gut", and don't push food during heavy vomiting. |
| Managed everyone at once | One adult with the sick child, one with the well sibling or elder. Separate cups, spoons and towels. Wash hands between them. |
| Washed laundry as usual | Fine — wash soiled bedding and clothes on a full cycle and dry them fully; don't shake them into the air. |
2) Tonight, in about 25 minutes
| # | Min | Do this |
|---|---|---|
| 1 | 2 | Write down: when vomiting started, whether diarrhoea has started, the time of the last pee, and the temperature if you have a thermometer. Take a photo of vomit or stool colour — colour matters (see the red flags). |
| 2 | 5 | Set up a "vomit station" beside the bed: a bin liner in a bucket, a spare towel, dry clothes, phone charger. This saves you time at 2 a.m. |
| 3 | 5 | If fluid is being lost: give small amounts of already-prepared oral rehydration solution (the pharmacy sachet, mixed exactly as the packet says) or their normal feeds, in small amounts they keep down. No plain water, diluted formula, juice, soft drinks or sports drinks as the fluid — those can make a child's fluid and salt balance worse. |
| 4 | 5 | Keep food coming: whatever they normally eat and tolerate, small and often. |
| 5 | 5 | Household bathroom routine: soap and water for everyone for the next few days, sanitizer only as a top-up. |
| 6 | 3 | Message the school, and ask the nurse whether other classes have reported the same thing. |
3) Constraints and avoid list
- I am not diagnosing and I am not changing any medication — nothing here starts, stops or adjusts a medicine for your child, the sibling, or the elder.
- No doses, volumes or schedules for medicine or fluid from me; those are a clinician's call.
- No mystery powders, no "family remedy" sachets from online shops, no prescription medicines bought online, no leftover antibiotics, and no anti-diarrhoeal medicine for a baby or young child.
- Don't make the child vomit, and don't give charcoal.
- Don't let sanitizer be the only clean, and don't skip the toilet-and-food handwash.
- Don't share cups, spoons, towels or medicines between the child, the sibling and the elder.
- Don't share food that has been sitting out at room temperature.
4) Decision tree — when to stop home care
Go now — emergency department or the local emergency number if your child has any of these:
- Cannot drink at all, or keeps bringing everything back up.
- Dehydration or shock signs: very sleepy or hard to wake, floppy, deeply sunken eyes, cold hands and feet, pale or blotchy skin, deep heavy breathing, or passing almost no urine.
- Vomit that is dark green (bile), or a belly that is swollen, hard or very tender.
- Blood or mucus in the stool, or diarrhoea together with fever.
- Belly pain in waves, pulling up the legs, going pale during the pain, or unexplained sleepiness between episodes.
- A severe headache with a stiff neck, vomiting after a head injury, a fit, fast or laboured breathing, or a rash that does not fade when you press it.
- Any of this in a baby under 3 months.
Same-day clinician — not tonight, but do not slip past tomorrow if: diarrhoea has run more than a couple of days or is worsening, there is fever with abdominal pain, the child is drinking poorly with diarrhoea, or the household cannot keep fluids in. And if the elder at home develops vomiting or diarrhoea, ask to be seen sooner — dehydration comes faster at that age.
5) What success looks like in 24 hours
Not "cured" — most of these settle over a few days, and I can't promise a timeline. Within 24 hours, a good sign is: fewer vomits and less diarrhoea, fluids staying down, some normal food being eaten, normal peeing, and more alert and playful. Keep the soap-and-water rule, the separate cups, and staying home from school until they've been symptom-free for 48 hours, for a couple of days after the last episode. That is where households usually pass it to each other.
6) Screenshot scripts
To the school:
> "Hi, my child has had vomiting/diarrhoea since [time]. Following the usual return-to-school rule, we'll keep them home until they've been symptom-free for 48 hours. Please send any class notice about cleaning or what to watch for. Thank you."
To a clinician, or to the nurse at the clinic:
> "Vomiting started [day, time]. Diarrhoea started [day, time]. Last pee [time]. Temperature [x] measured at [time]. [He/She] [is/isn't] keeping fluids down. Vomit colour: [yellow / green]. Blood in stool: [yes / no]. Recent antibiotics or travel: [yes / no]."
Bring with you: a photo of the vomit or stool colour, the times above, what they ate and drank, and any information about the classmates who are off.
Where I have no coverage: whether your child's school currently has a confirmed outbreak, and which germ is behind it. The school nurse or your local health centre can tell you whether a cluster has been reported there.
