The 2026 (B.E. 2569) Lat Krabang Road Flooding: What Was Reported

According to Krungthep Turakij (Bangkok Biz News) on 4 October 2026 (B.E. 2569), several stretches of Lat Krabang Road had standing water about 20 to 30 centimetres deep, and small vehicles were advised to avoid the route. That report covers road conditions only and gives no details about individual homes, so the family story below is an example case to illustrate common risks.

Across Bangkok, Thai PBS reported that rain on 25 and 26 September 2026 peaked at 210.0 mm in Chatuchak, 205.5 mm in Wang Thonglang and 203.5 mm in Saphan Sung, with more than 300 mm falling in about 48 hours. All 50 districts were declared disaster zones on 26 September 2026. Flooded points rose from 43 at 18:30 on 25 September to 135 on 27 September, and a DDPM figure for 6 October 2026, reported by Bangkok Biz News, put affected Bangkok households at around 329,000.

Nationally, the DDPM report as of 06:00 on 7 October 2026 (B.E. 2569), published by the Government Public Relations Department, listed 27 provinces plus Bangkok, 123 districts, 984 subdistricts, 1,154,875 households and more than 3.1 million people affected. Figures change daily; follow Lat Krabang district office and Bangkok Metropolitan Administration announcements.

A Typical Scenario: A Toddler's Ground-Floor Play Corner

Example case (not a real customer review). Prae and her husband live in a two-storey townhouse in a small soi off Lat Krabang Road. Their son Phum is fourteen months old, learning to walk and putting toys in his mouth. The ground-floor living room is his play corner, with foam crawling mats, a basket of plastic toys, soft dolls and cloth books.

On the night of heavy rain, water on Lat Krabang Road rose until small cars could not pass, and water in the soi reached the front door. Some seeped under it and soaked the edges of the foam mats. Prae carried the toys upstairs, but a few soft dolls left on the floor got wet. The next day, once the soi drained, she mopped the floor with ordinary floor cleaner, propped the mats up to dry, put the dolls out in the sun and then laid everything back down for Phum to play.

Two days later Phum had a fever, vomited several times and then had watery diarrhoea many times a day. A paediatrician assessed him for dehydration and advised on care, explaining that children his age catch gut viruses easily, especially from hands and toys, and that rotavirus is one of the important common causes in young children, though only a doctor can say which germ is responsible. This is a common picture in homes with toddlers after a flood.

What Is Rotavirus and Why Are Young Children at Risk After Floods?

Rotavirus is a leading cause of severe diarrhoea in infants and young children worldwide, according to the World Health Organization (WHO). Children aged roughly six months to two years are affected most often. Older children and adults can be infected too, usually with milder symptoms, which means an adult with few symptoms can pass it to a child without realising.

Rotavirus spreads by the faecal-oral route. Large amounts of virus leave the body in stool and end up on hands, nappies, surfaces and toys. When a child mouths a toy, or an adult changes a nappy and then prepares milk without washing properly, the virus moves on. It can survive on hard surfaces and toys for a considerable time, so it spreads easily in homes with several children, nurseries and shelters.

Floods raise the risk further. Urban floodwater often mixes with drain and septic water, so mud and water marks left on floors may carry faecal germs. Water supply or storage can be disrupted, power cuts make it harder to wash bottles in hot water, and tired parents may skip handwashing steps. All of this gives young children more chances to pick up gut infections.

Rotavirus vaccine

An oral rotavirus vaccine for infants is the most important protection. It is given within set age windows, so parents should check their child's vaccination book and talk to a paediatrician or local clinic. No room treatment or cleaning replaces vaccination.

Rotavirus Symptoms and the Dehydration Signs That Mean See a Doctor Now

Symptoms usually begin about two days after exposure. Children often start with fever and vomiting, followed by watery diarrhoea several times a day, sometimes with tummy pain, fussiness and poor appetite. Diarrhoea may last several days. The greatest danger for young children is dehydration, which can develop faster than parents expect.

See a doctor straight away if you notice:

• Much less urine, or nappies staying dry for many hours.
• Crying without tears, or a dry mouth and tongue.
• Sunken eyes, or a sunken soft spot in a baby.
• Unusual drowsiness, difficulty waking or unusual restlessness.
• Vomiting so much that milk or fluids cannot stay down.
• Blood or mucus in the stool, high fever or a seizure.

This article gives no treatment or dosing advice. Fluids and oral rehydration should follow a doctor's or nurse's guidance. In an emergency go to hospital or call 1669 in Thailand. Diarrhoea in children after a flood can also be caused by norovirus, E. coli, Salmonella or other germs, and only a doctor can diagnose it.

Others who need extra care include premature babies, children with chronic conditions, grandparents who help care for a sick child, and anyone with weakened immunity.

Rotavirus Hotspots in Lat Krabang Homes: Toys and Children's Rooms

Young children live close to the floor. They crawl, sit and roll there, so the risk spots in a home are at a child's eye level, not an adult's.

1. Plastic toys and teethers, mouthed dozens of times a day. If they fell where water seeped in, wash them before use.
2. Soft dolls, cloth books and absorbent toys. If floodwater soaked them, they are very hard to clean properly and should usually be thrown out.
3. Foam crawling mats and rugs, where water and mud get underneath and into joins, feeding damp, musty smells and mould.
4. Changing tables, nappy bins and baby baths, in direct contact with stool.
5. Bottles, teats and milk preparation equipment, which must only be washed with clean water.
6. Cots, cot rails and high chairs that children grip and chew.
7. Door handles, light switches and remotes touched by adults after nappy changes.

Lat Krabang has townhouses, housing estates, shophouses and dormitories near universities and the industrial estate. Many homes use the ground floor as a living room and play area. When roads flood and water backs up into the sois, the ground floor is hit first. Even shallow water leaves dampness under foam mats, tiles and wall edges, enough for musty odour and mould within days.

The Impact When a Child Falls Ill After a Flood

A child with diarrhoea and vomiting may need hospital care for dehydration, and siblings and carers, especially grandparents, may fall ill too. Parents take leave while traffic on flooded Lat Krabang Road makes every hospital trip longer. Costs add up: treatment, travel, new nappies and supplies, replacement toys and mats, and cleaning. Many parents also feel guilty for putting mats back too soon. For nurseries and kindergartens, several sick children at once can mean temporary closure and lost parent confidence.

Why Sunlight, Mopping or Scented Spray Is Not Enough for a Child's Room

• Sunlight does not clean the whole item. It dries the outside, but the stuffing of a doll or the core of a foam mat that soaked up floodwater may stay damp and hold germs from the mud.
• Ordinary floor cleaner is made for shine and scent, not for faecal germs on toys that children put in their mouths.
• Hand gel does not replace handwashing. After a nappy change, wash with soap and clean water.
• Air freshener and scented sprays do not suit children's rooms. They only mask musty odour and may irritate small noses.
• Under the mats and behind toy shelves are where hidden dampness lingers, and musty smells and mould often start there.

The right approach is to discard flood-soaked items that cannot be cleaned, wash plastic toys with soap and clean water, use a disinfectant suitable for children's items as the label directs, rinse again with clean water before play, clean floors and touch points, then dry everything thoroughly. Ozone is an additional step after that, for the air, musty smells and corners a cloth cannot reach.

Ozone for Children's Rooms After the 2026 Lat Krabang Flood With WHD

The WHD residential and building ozone disinfection service uses ozone gas (O3), which reacts with the structures of microorganisms and odour molecules and then reverts to oxygen (O2) on its own. It leaves no chemical film on toys, floors or walls, which is why many parents are interested: they do not want residue in a room where their child crawls.

According to the company's certification data, WHD's ozone system was tested by Thailand's Department of Medical Sciences and Intertek (UK) and reduced viruses, bacteria and fungi by 99.99%. These results cover groups of organisms under the test conditions; they are not a rotavirus-specific result. Ask the WHD team for the documents or test data, or visit the certificates page.

Once the room is clean and dry, ozone suits a child's room for:

• Reducing musty, muddy and drain odours carried in with standing water.
• Reducing germs in the air and on air-exposed surfaces, including under the cot and behind cabinets.
• Reducing airborne mould spores that follow post-flood dampness.
• A final step before new mats go down and the child plays in the room again.

The WHD process for a child's room

1. Survey. Send photos of the playroom, living room and smelly spots over LINE. The team estimates area and zones.
2. Clean and dry first. Discard flood-soaked soft toys and foam, wash plastic toys, clean floors and touch points, and ventilate until dry.
3. Empty and seal. Children, adults, pets and plants all leave. Close doors, windows and vents.
4. Run the ozone cycle, about 30 minutes per zone depending on room size.
5. Rest and ventilate. Wait for the ozone to break down, then ventilate as the technician directs. For a child's room, ventilate fully before the child comes back in.
6. Re-entry. Once the technician confirms, lay down the mats and bring in the washed toys.

WHD is based in Bang Khae district, Bangkok 10160, and serves Bangkok including Lat Krabang, with dates arranged by phone at 065-556-6294 or LINE @whd268. Same-day arrival cannot be guaranteed. Prices depend on area and number of zones and are quoted case by case. Under the current promotion, ozone jobs of 15,000 baht or more receive a free medical-grade disinfectant spray.

Is Ozone Dangerous? What to Watch for in a Child's Room

High-concentration ozone irritates the airways, especially for young children whose lungs are still developing. It must only be used in an empty, sealed room, and people return only after the rest and ventilation period the technician sets. Done this way, it breaks down to oxygen and leaves no residue.

• No children, adults, pets or plants in the room during treatment.
• Never open the door while the machine is running.
• Young children, people with asthma and older adults should wait until the room is fully ventilated.
• Take formula, baby food, medicines and bottles out first.
• Tell the technician about rubber toys or materials you do not want exposed, or remove them.
• If your child is ill, see a doctor first. Treating a room does not treat a child.
• Ozone does not replace washing toys, discarding soaked items or vaccination.

10 Reasons Lat Krabang Homes With Young Children Should Consider Ozone After the 2026 Flood

1. No chemical film. Ozone reverts to oxygen, suiting rooms where children crawl, once ventilated.
2. It reaches corners a cloth cannot, under the cot, behind toy shelves and in room corners.
3. It reduces musty and drain odour at the source instead of scented sprays that may irritate children.
4. Company certification data: Department of Medical Sciences and Intertek testing, 99.99% for viruses, bacteria and fungi. See service details.
5. It helps with mould spores, common triggers for allergy and stuffy noses in children.
6. It is quick, about 30 minutes per zone plus rest and ventilation.
7. It suits nurseries and early childhood centres that want an extra step before reopening.
8. It gives parents peace of mind that the room has been cleaned, dried and treated in order.
9. Clear safety guidance before and after treatment. Talk to WHD.
10. It combines with other services such as disinfection spraying.

Before and After: A Toddler's Play Corner in a Lat Krabang Townhouse

Results vary by room, prior cleaning and ongoing care. This is an illustration.

Example Case: A Small Home Nursery in a Lat Krabang Soi

Example case (not a real customer review). Teacher Oi runs a home nursery for about ten children in a large single-storey house in a Lat Krabang soi. During the heavy rain in late September, water reached the front yard and seeped into part of the playroom. She closed temporarily, two children fell ill with diarrhoea at home, and parents kept asking when she would reopen and how she would clean.

She contacted WHD on LINE with photos of the playroom, nap room and children's bathroom. The team advised discarding flood-wet nap mats and soft toys, washing all plastic toys, cleaning the changing area and bathroom following public health guidance, and drying everything first. Ozone was then scheduled in three zones, with nobody in the building during treatment and everyone returning after ventilation as the technician directed.

She also updated daily routines: a separate basket for mouthed toys washed every day, a handwashing sign at the changing table, and asking parents to keep children with diarrhoea at home until a doctor says they can return. Parents felt more confident seeing clear steps.

Checklist: Rotavirus Prevention and Children's Room Recovery After the 2026 Lat Krabang Flood

Before ozone

• If your child has fever, vomiting, diarrhoea or dehydration signs, see a doctor now.
• Check the vaccination book and ask a paediatrician about rotavirus vaccine for your child's age.
• Wash hands with soap after nappy changes and the toilet, and before preparing milk or food.
• Seal used nappies in bags and clean the changing area after each use.
• Discard soft dolls, cloth books, foam mats and rugs soaked by floodwater.
• Wash plastic toys with soap, disinfect per label, rinse with clean water and air-dry.
• Wash bottles and teats only with clean water, and use boiled or bottled water for formula.
• Clean floors, wall edges and touch points, and ventilate until fully dry.

On the day and afterwards

• Move children, adults, pets and plants out.
• Take formula, baby food, medicines and bottles out of the room.
• Do not enter while the machine runs, and ventilate fully before the child returns.
• Lay new mats only on a completely dry floor, and wash mouthed toys regularly.
• If musty smells return, find the damp source and fix it.

FAQ: Rotavirus, Child Diarrhoea After Floods and Ozone in Lat Krabang

What are the symptoms of rotavirus?

Usually fever and vomiting first, then watery diarrhoea several times a day for several days. Dehydration is the main danger, so see a doctor if signs appear.

When should I take my child to a doctor for diarrhoea after a flood?

Straight away if there is little urine, dry nappies for hours, crying without tears, drowsiness, vomiting that stops feeding, bloody stool, high fever, or if the child is a young baby.

How does rotavirus spread?

By the faecal-oral route, through hands, nappies, toys and contaminated surfaces. Children who mouth objects are at high risk.

Can my child still use toys that got flood water on them?

Hard plastic toys can be reused after washing with soap, disinfecting per label and rinsing. Soft dolls, cloth books and foam toys soaked by floodwater should be thrown away.

Is the rotavirus vaccine necessary?

It is the most important protection. An oral vaccine is given to infants within set age windows. Ask a paediatrician or local clinic.

Can ozone help with rotavirus?

According to company certification data, WHD's ozone service reduces viruses, bacteria and fungi by 99.99%, but there is no rotavirus-specific test. Vaccination, handwashing and washing toys are the core of prevention. Ask WHD for the test data.

Is ozone in a child's room dangerous?

It is safe when done in an empty, sealed room with nobody inside during treatment, and when everyone returns only after full ventilation as the technician directs. Ozone reverts to oxygen with no residue.

How do I get rid of musty smell in a child's room after a flood?

Remove damp foam and rugs, find hidden moisture under mats and at wall edges, dry the room completely, then use ozone for odour trapped in the air. Avoid scented sprays in children's rooms.

How much does ozone treatment cost?

It depends on room size and zones. WHD quotes case by case at 065-556-6294 or LINE @whd268. Jobs of 15,000 baht or more receive a free medical-grade disinfectant spray under the current promotion.

Is there ozone service near me in Lat Krabang?

WHD is in Bang Khae, Bangkok, and serves Bangkok including Lat Krabang, with dates arranged by phone or LINE.
