Flood Points in Kut Lo, Ban Yang and Kaset Sombun: What the PRD Reported

According to the Government Public Relations Department, on 27 September 2026 the Governor of Chaiyaphum inspected six flood points in Kaset Sombun district, caused by heavy rain and the Lam Nam Phrom overflowing:

• Lam Huai Khae at Ban Mueang Kao, Ban Yang subdistrict
• The bridge over the Lam Nam Phrom at Ban Kut Lo
• Ban Rai, Moo 7, Ban Yang subdistrict
• Ban Tha Kham Rai Duea Samakkhi School, Moo 8, Ban Yang subdistrict
• Ban Hua Saphan, Moo 8, Kut Lo subdistrict
• Khum Klang Nok, Kaset Sombun subdistrict municipality

Machinery was mobilised to drain the water, with round-the-clock monitoring (source: PRD). The report did not give water depths or household numbers for each point, so this article does not guess them.

Nationally, the PRD reported Department of Disaster Prevention and Mitigation figures as of 06.00 on 7 October 2026: 27 provinces plus Bangkok, 123 districts, 984 subdistricts, 1,154,875 households and more than 3.1 million people affected. These figures change daily.

What stands out in Kaset Sombun is the mix of rural villages, a town neighbourhood and a school. Post-flood risk is therefore not only inside homes but also in buildings that many children share.

Example Case: A Mother by the Lam Nam Phrom and Her Children's Return to School

This is a typical scenario based on common situations after riverside floods, not an interview with a real person.

Kaew lives with her two children in a single-storey concrete house near the bridge over the Lam Nam Phrom. On the night of the heavy rain, the river rose quickly and spilled into the village road. She took the children to a relative's house on higher ground, where children from several families slept in one room and shared cups, towels and toys.

When the water receded, she found a thin layer of mud across the floor, swollen plywood at the bottom of the wardrobe, a smelly bathroom and cloudy sediment in the water tank behind the house. She cleaned for two days. Then her younger child developed red, watery eyes, and her older child had a cough and low fever. The doctor at the community hospital advised keeping the children home until they improved and washing hands often.

Meanwhile, the parents' LINE group was asking when the school would reopen and whether buildings that had been flooded were safe. Kaew's question was simple: if homes and classrooms are washed but germs remain, will the children just keep passing illness around?

Flood Germs in Kut Lo, Ban Yang and Kaset Sombun: Children, Schools and Shared Buildings

When a river floods villages, a town neighbourhood and a school, risk comes in two layers: germs the water and mud bring in, and germs that pass from person to person when people crowd together and then return to the same buildings. Here are twelve germs to know, with how the flood spreads them, where they hide, who is at risk and how to prevent them. This is general information, not treatment advice; see a doctor about any symptoms.

1. Leptospira (leptospirosis by the Lam Nam Phrom)

Overflow from the river crosses paddies, streams and grazing land, carrying bacteria from the urine of rats, cattle and buffalo into the villages. Rats escaping the water also move into houses, storerooms and closed classrooms. It survives in mud on floors, school grounds, under buildings, in storerooms and puddles. Sudden high fever, headache, strong calf pain and red eyes are typical. People cleaning mud, including caretakers, teachers and volunteers, are most exposed. Wear boots and gloves, keep children away from mud and puddles, cover cuts and see a doctor quickly if fever follows.

2. Adenovirus (pink eye after floods)

Conjunctivitis is common during floods because people crowd together, share face towels and rub their eyes with dirty hands. Adenovirus survives on surfaces for a long time and moves easily from hand to eye. It hides on door knobs, school desks, stair rails, towels, pillowcases and shared toys. Red, watery, gritty eyes with discharge are typical, sometimes with fever and sore throat, and it spreads fast among pupils and family members. Wash hands often, avoid rubbing eyes, keep towels personal and follow the doctor's advice on staying home.

3. Enterovirus 71 and Coxsackievirus (hand, foot and mouth disease)

Spread through saliva, nasal mucus, blister fluid and faeces. Kindergartens and childcare centres reopening after a flood are easy places for it to spread if toys and floors are not thoroughly cleaned. It hides on toys, nap mats, cups, spoons and children's toilets. Fever, mouth ulcers and blisters on hands, feet and buttocks are typical; seek urgent care if a child is drowsy, vomits repeatedly or has jerky movements. Clean and disinfect toys and keep sick children home. Hand, foot and mouth virus is listed on WHD's service page.

4. Respiratory Syncytial Virus (RSV)

RSV circulates among children in the rainy season, and crowding plus long hours in wet clothes help it spread through droplets and hands. It lingers on frequently touched surfaces, toys, cots and shared blankets. Runny nose, cough, fever, fast or wheezy breathing are common; babies, toddlers, older people and those with heart or lung disease are at greatest risk. Wash hands before holding babies, separate children with symptoms and seek care for laboured breathing. RSV is listed in WHD's service information.

5. Influenza A, including H1N1

Flu circulates all year and peaks in the rainy season. Shelters, crowded relatives' homes and whole classes returning at once help it spread. It sits on desks, chairs, door knobs, remotes and phones. High fever, body aches, cough and exhaustion are typical; young children, older people, pregnant women and people with chronic illness risk complications. Mask up when ill, wash hands and ask a health worker about yearly flu vaccination. H1N1 is listed in WHD's service information.

6. Norovirus (vomiting and diarrhoea outbreaks)

Norovirus spreads through faeces and vomit via water, food and surfaces. When meals and drinking water are distributed to many people during a flood, one sick person can start a cluster of cases. It hides in bathrooms, taps, dining tables and wherever someone has vomited. Sudden vomiting, diarrhoea and cramps can dehydrate children and older people. Clean up vomit wearing gloves, then disinfect, and sick people should not prepare food for others. Norovirus is listed in the CHEMGENE product information.

7. Salmonella Typhi (typhoid fever)

Typhoid spreads through water and food contaminated by the faeces of patients or carriers. Floodwater mixing with septic tanks and community water supplies raises the risk. It hides in water tanks, shallow wells, flooded drinking-water machines and food prepared with unclean hands or water. Persistent high fever over several days, headache, weakness and abdominal pain are typical. Drink bottled or boiled water, clean and disinfect water tanks and see a doctor for prolonged fever. Salmonella is a genus named in the product information; ask WHD for test data on the typhoid type specifically.

8. Bacillus cereus (food poisoning from rice left out too long)

Found in soil and dust, it forms heat-resistant spores. During floods, when power is cut and fridges stop working, large batches of cooked rice and food left at room temperature for hours let it multiply and produce toxins. It hides in rice cookers, food boxes and kitchens still dusty with mud. Vomiting or diarrhoea within hours of eating is typical, usually short-lived but dehydrating for children and older people. Eat freshly cooked food, refrigerate leftovers promptly and clean pots and the kitchen thoroughly.

9. Legionella pneumophila (water systems in buildings left closed)

Legionella grows in warm, stagnant water inside pipes, tanks and building water systems. Schools, offices and homes closed during a flood leave water sitting in pipes far longer than normal. It hides in showerheads, unused taps, rooftop tanks and water heaters, and infects people who breathe in contaminated droplets, causing anything from flu-like illness to pneumonia. Older people, smokers and those with weak immunity face higher risk. Before reopening, run taps and showers to flush them, clean water tanks and have building managers check water systems according to public health advice.

10. Necator americanus (hookworm from walking barefoot in mud)

Hookworm larvae live in soil contaminated by faeces and can burrow straight through the skin. Floods leave sewage in yards and school fields, so walking barefoot is risky. It hides in damp soil near latrines, freshly drained lawns, dirt paths and vegetable plots. An itchy rash where larvae enter, sometimes cough and abdominal pain, and anaemia with long-term infection are possible; barefoot children are most at risk. Always wear shoes on soil and ask a health worker about checking or deworming. As a parasite, hookworm is prevented mainly by footwear and hygiene, not by spraying.

11. Stachybotrys chartarum (black mould in wet walls and ceilings)

This black mould favours cellulose materials that stay wet for days, such as gypsum board, paper, plywood and ceiling panels, which are common in homes and classrooms alike. It hides in the lower parts of gypsum walls, leaking ceilings, plywood cabinets, document boxes, textbooks and notice boards, irritating the nose, eyes and throat and triggering asthma in allergic children. Remove mouldy porous materials, dry buildings fast and wear a mask when stripping out. Fungi and mould are listed in WHD's service information as covered.

12. Alternaria (allergy-triggering mould in damp homes)

A common mould from soil and plants that grows on window frames, door seals, curtains and muddy materials once a house stays damp. It causes sneezing, runny nose, itchy eyes and asthma flare-ups. Children with allergies or asthma should stay away from mouldy rooms until cleaning is finished. Wash curtains and rugs, sun-dry them, ventilate and dry window frames.

How this links to disinfection in homes and schools: person-to-person germs such as adenovirus, hand, foot and mouth virus, RSV, flu and norovirus sit on frequently touched surfaces, while water and soil germs stay in mud and damp. CDC and WHO advise cleaning, drying and then disinfecting. According to the product information, organisms WHD names include RSV, H1N1, H5N1, hand, foot and mouth virus, norovirus, Salmonella and fungi. Leptospira, adenovirus, Bacillus and Legionella are not named individually but belong to the bacteria or virus groups the product says it covers. For hookworm, a parasite, shoes and hygiene are the key. Ask WHD directly for organism-specific test data.

What Kaset Sombun Families and Schools Risk by Skipping Disinfection

Illness circulating in class: when schools reopen, children who caught pink eye, hand, foot and mouth disease or flu while crowded together can pass it on. If desks, door knobs and toilets have not been cleaned and disinfected, illness can keep coming back.

Parents missing work: every sick child means a parent taking leave or losing a day's wages, on top of flood losses.

Disrupted learning: a school that has to close again because of a post-flood outbreak costs children more lessons and leaves parents searching for childcare.

Grandparents at risk: children bring respiratory and diarrhoea germs home to older relatives with chronic illnesses.

Community confidence: shops, restaurants and public places in the municipality want customers to know the premises have been cleaned and disinfected.

Why Washing Homes and Classrooms After the Lam Nam Phrom Flood Is Not Enough

• Person-to-person germs are not only in the mud: pink-eye, flu and hand, foot and mouth viruses sit on desks, rails and toys that look clean.
• Shared buildings have hundreds of touch points: desks, chairs, knobs, taps and switches are easy to miss when wiping by hand.
• Household bleach does not suit every surface: it can corrode metal, damage fabrics and learning materials and irritate children with its strong smell.
• Hidden damp: black mould can start behind notice boards or above ceilings before it is visible.
• Water systems need attention: pipes and tanks unused for days must be flushed and cleaned.

CDC flood guidance sets out the order: remove mud, clean with soap and water, disinfect, and dry quickly to prevent mould. WHO and Thailand's Department of Disease Control add hand hygiene, safe water and food, separating sick people and prompt medical care. Professional spraying makes the disinfection step thorough and consistent across many rooms. It does not replace cleaning, drying or seeing a doctor.

How WHD's Post-Flood Disinfection Spraying Works for Homes and Buildings in Kaset Sombun

World Health Disinfection (WHD) is based in Bang Khae, Bangkok 10160, and has no branch in Chaiyaphum. Jobs in Kut Lo, Ban Yang or the Kaset Sombun municipality are arranged by phone on 065-556-6294 or LINE @whd268. Visit dates depend on the schedule and road conditions, so same-day service cannot be promised.

According to the service information, trained technicians spray and/or apply ULV (Ultra Low Volume) fine mist using CHEMGENE HLD4H, a medical-grade UK disinfectant containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. The page lists viruses, bacteria and fungi including COVID-19, RSV, H1N1, H5N1 and hand, foot and mouth virus, claims 99.99% effectiveness, calls the product broad-spectrum, and cites the Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019. Listed customers include hospitals and schools, which suits a community with a school among its flood points.

1. Survey: send photos, building size, number of rooms and priority areas such as kindergarten rooms, toilets, the canteen or children's bedrooms via LINE.
2. Clean first: remove mud, wash surfaces with clean water and detergent, strip out mouldy materials and dry. Spraying always follows this step.
3. Zone: classrooms, toilets, canteen and staff rooms, or at home the kitchen, bathroom and bedrooms, are planned separately; food, dishes and personal learning materials are put away; people and pets leave the zone.
4. Spray: focus on touch points such as desks, chairs, knobs, rails, taps, switches, toilets and floors, with ULV mist in large rooms.
5. Re-entry: the service information says about 30 minutes before normal use; follow the technicians' on-site timing and ventilate before children come back in.

The promotion includes a free CHEMGENE spray bottle and WELLGIENIC wet tissues, and tax invoices are available. For rooms that still smell musty, ask about residential ozone disinfection.
