Childcare Cleaning After a Gastro or Illness Outbreak: Victorian Protocol

Quick answer
In Victoria, two or more related cases of gastro in a children’s service is treated as an outbreak and should be reported to the Department of Health (1300 651 160). During the outbreak, clean then disinfect toilets, nappy areas and high-touch surfaces at least twice daily with a chlorine-based disinfectant, clean vomit and diarrhoea immediately with a spill kit, remove soft toys, discard playdough and stop sandpit and water play. Sick children are excluded until 48 hours after symptoms stop. Finish with a thorough final clean once the outbreak is declared over.
A gastro outbreak can move through a childcare centre in days, taking out children, families and educators. Cleaning will not end an outbreak on its own — exclusion and handwashing matter as much — but poor cleaning will keep it going.
This guide follows the Victorian Department of Health guide to managing gastroenteritis outbreaks in children’s centres and the NHMRC Staying Healthy guidelines. Always follow any specific advice the Department gives your service.
Key takeaways
- Gastro (often norovirus) spreads fast and survives on surfaces — detergent alone is not enough during an outbreak.
- Use a chlorine-based disinfectant: many other products are unreliable against norovirus.
- Clean before disinfecting, every time.
- Fogging and misting are not a substitute for physical cleaning.

Is it an outbreak? Who to notify
- Outbreak definition: two or more cases of vomiting and/or diarrhoea linked by time and place (for example, the same room in the same few days).
- Notify: the Victorian Department of Health on 1300 651 160 — they can advise on control measures and testing.
- Notify your regulatory authority if required under the National Regulations, and inform families.
- Exclusion: children and staff with gastro stay home until 48 hours after the last episode of vomiting or diarrhoea.
Cleaning up vomit and diarrhoea
- 1
Clear the area
Move children away. Vomit can spread virus particles through the air around it.
- 2
Protect yourself
Disposable gloves, apron and, for large spills, a mask and eye protection.
- 3
Remove the bulk
Use absorbent granules or paper towel, scoop into a plastic bag and seal it.
- 4
Clean
Clean the area with detergent and warm water, working from the outside in.
- 5
Disinfect
Apply chlorine-based disinfectant at the label dilution and leave for the full contact time. Extend the clean about 2 metres around a vomit spill.
- 6
Dispose and wash
Bag gloves and cloths, put soiled fabrics in a sealed bag for hot washing, then wash hands thoroughly.
Keep spill kits stocked
Every room should have a body-fluid spill kit: gloves, apron, mask, absorbent granules, scoop, bags, disposable cloths and disinfectant. Restock after every use.
Daily cleaning during the outbreak
- Clean then disinfect toilets, potties, taps, flush buttons and door handles at least twice daily
- Clean then disinfect nappy change tables after every change
- Disinfect all high-touch surfaces at least twice daily
- Remove soft toys and hard-to-clean toys; wash and disinfect plastic toys twice daily
- Discard playdough in affected rooms; stop sandpit and water play
- Use disposable cloths or launder cloths on a hot cycle after each use
- Launder soiled linen separately on the hottest suitable cycle
- Keep affected rooms’ equipment in those rooms where possible
- Stop children helping with food preparation; reinforce handwashing
Want this cleaning done for your centre?
WWCC-verified, police-checked teams cleaning after hours across Melbourne. A typical 3-hour visit is around $180 + GST, with one fixed price per visit after a free walk-through.
The final clean when the outbreak ends
Once the Department confirms the outbreak is over (usually after a period with no new cases), do a thorough final clean of affected rooms before returning to normal routines. This is a top-to-bottom clean and disinfection of all hard surfaces, toys, equipment, bathrooms and nappy areas, plus washing of all linen, soft furnishings and soft toys.
- Steam or hot-water extract carpets and rugs in affected rooms — see the carpet cleaning guide
- Wash cot sheets, blankets, cushions, dress-ups and soft toys
- Replace sandpit sand if it may have been contaminated
- Restock spill kits and record the clean in your cleaning log
What about fogging?
Disinfectant fogging or misting does not remove the dirt and organic matter that protect viruses, and adds chemical exposure. Physical cleaning followed by disinfection is what the guidelines recommend.
When to bring in professional help
Twice-daily disinfection on top of normal programming stretches educators thin. An outbreak visit from a professional team typically costs $250–$600 + GST depending on centre size and scope. Our childcare cleaning team can add midday visits and run the final clean after hours so rooms are ready the next morning.
Frequently asked questions
What is the best disinfectant for gastro in childcare?
A chlorine-based (bleach) disinfectant, used after cleaning with detergent. Many other disinfectants are not reliably effective against norovirus.
How long should a child stay home after gastro?
In Victoria, children with vomiting or diarrhoea should be excluded until 48 hours after symptoms stop.
Do we need to close the centre for a gastro outbreak?
Usually not. The Department of Health will advise on control measures. Closure is rare and only recommended in specific circumstances.
How much does outbreak cleaning cost?
A professional outbreak clean in Melbourne typically costs $250–$600 + GST, depending on the size of the centre, number of affected rooms and whether carpets and soft furnishings are included.
