Flooding in Chai Nat Town, According to News Reports

According to MGR Online on 25 September 2026, more than 18 hours of continuous rain in Mueang Chai Nat caused standing water at several points:

• Phrom Prasoet Road: about 20 to 30 centimetres, worst at the Wat Si Wichai three-way junction.
• Wongto Road: about 10 to 20 centimetres.
• Chai Nat Provincial Hall area: about 20 to 30 centimetres.
• Around Anuban Chai Nat School: about 20 centimetres.
• Schools in the area announced a one-day closure.

These figures reflect the time of reporting; urban water levels change with rainfall and drainage, so follow Chai Nat Town Municipality and provincial announcements as well. Nationally, figures from the Department of Disaster Prevention and Mitigation, published by the Government Public Relations Department as of 06:00 on 7 October 2026, showed flooding affecting 27 provinces plus Bangkok, 123 districts, 984 subdistricts, 1,154,875 households and more than 3.1 million people.

From a hygiene point of view, what stands out in Chai Nat is that the water pooled in the centre of town: government offices, schools, shops, markets and residential lanes. Many children travelled past flooded roads, parents waded through water on the school run, and when schools closed, children spent more time at home. If a home still holds floodwater residue and damp, children are in contact with germs on floors, toys and furniture all day long.

Example Case: A Home Off Phrom Prasoet Road with a Toddler Who Plays on the Floor

Note: this is a typical scenario compiled from situations commonly seen after urban flooding. It is not the account of any specific customer and does not relate to any particular school or agency.

Nok is the mother of a four-year-old boy. Her single-storey house sits in a narrow lane off Phrom Prasoet Road. On the morning the rain would not stop, water in the lane rose until it spilled into the carport and under the front door into the living room. The rubber play mat where her son builds blocks, a box of toys on the floor and the base of the sofa were soaked in brown, murky water that smelled like a drain, because the drain outside could not cope and had backed up.

When the water receded, Nok swept it out, mopped with the floor cleaner she had, rinsed the toys in plain water and dried them in the sun. The next day her son was back on the floor, putting toys in his mouth as small children do. A few days later he had a low fever, loose stools several times a day and no appetite. Nok took him to a doctor and followed the advice until he recovered, but she began to wonder whether the house was truly clean. A musty smell lingered under the sofa, and small black spots had appeared along the bottom of the walls.

She contacted WHD on LINE. The team advised her to discard the rubber mat and any fabric or foam toys that had absorbed floodwater, scrub the floor and lower walls, open the house to dry, and then book spraying for the living room, bedroom, bathroom and carport. During spraying the family and their cat waited outside and came back at the time the technician gave. The same can happen to any family with young children in Chai Nat town, whether on Phrom Prasoet Road, Wongto Road or near the provincial hall.

Why Children in Chai Nat Face Higher Post-Flood Germ Risk

Young children come into contact with germs far more than adults. They crawl and sit on floors, touch everything and put their hands in their mouths, love splashing in puddles, and do not wash their hands thoroughly. Their immune systems are still developing, and their small bodies lose fluids quickly through diarrhoea or vomiting. When schools reopen, a child infected at home can carry germs into the classroom, so some infections, such as stomach viruses or hand, foot and mouth disease, can spread in clusters.

Older adults are also at risk: immunity weakens with age, and many live with diabetes, high blood pressure or lung disease, which can make infections more serious. Recovering a home after flooding in Chai Nat is not only about making it look clean. It is about protecting the most vulnerable people in the family.

Flood Germs in Chai Nat Town: Ten Organisms Parents Should Know

Urban floodwater in Chai Nat is a mix of rain, drain water, mud and street dirt, so the germs that follow include bacteria, viruses, fungi and some parasites. This is general prevention information, not treatment advice. If a child or family member becomes unwell, see a doctor and mention floodwater contact.

1. Rotavirus, a Leading Cause of Diarrhoea in Young Children

How floods spread it: rotavirus passes through faeces. When drains back up and contaminated water enters a home, the virus can persist on floors, toys and surfaces. Where it hides: floors where children crawl, plastic toys, cot rails, bathrooms and nappy-changing areas. Symptoms and risk groups: vomiting, watery diarrhoea and fever; children under five are most at risk of dehydration. Prevention: wash hands before feeding and after nappy changes, wash toys with soap and clean water before disinfecting, ask a doctor about age-appropriate vaccination, and seek care at once if a child becomes drowsy, passes little urine or cannot drink. Rotavirus belongs to the virus group WHD's product information says it covers in general; no specific test result is listed, so ask WHD if you need data.

2. Enteroviruses and Hand, Foot and Mouth Disease

How floods spread it: enteroviruses such as coxsackievirus and enterovirus 71 spread through saliva, nasal mucus, blister fluid and faeces. In the rainy season, children cluster indoors or in shelters while surfaces stay damp, which helps the virus pass on. Where it hides: toys, spoons, shared cups, door handles and stair rails. Symptoms and risk groups: fever, mouth ulcers, and a rash or blisters on the hands, feet and buttocks; kindergarten and early primary children are most at risk. Prevention: separate personal items, wash hands often, clean toys daily, and keep a sick child home and see a doctor. According to WHD's service and product information, hand, foot and mouth disease virus is one of the organisms stated to be covered.

3. RSV (Respiratory Syncytial Virus) in the Rainy Season

How floods spread it: RSV does not come from floodwater, but it peaks in the rainy season, and wet, tired children in crowded spaces catch it through droplets and contaminated hands. Where it hides: cot rails, toys, phones, remote controls and dining tables. Symptoms and risk groups: runny nose, cough, fever, fast or wheezy breathing; babies, toddlers and older adults risk pneumonia. Prevention: wash hands before holding babies, separate sick family members, clean shared touch points, and seek care urgently for breathing difficulty. According to WHD's service information, RSV is one of the organisms stated to be covered.

4. Shigella and Dysentery

How floods spread it: Shigella spreads easily even in small doses, through water, food and hands contaminated with faeces, so sewage-tainted floodwater raises the risk. Where it hides: taps, sinks, chopping boards, food containers and toilets. Symptoms and risk groups: diarrhoea with mucus or blood, straining and fever; young children and older adults face more severe illness. Prevention: drink boiled or bottled water, wash produce in clean water, discard flood-touched food, and wash hands after using the toilet. Shigella is within the bacteria group the product says it covers in general, without a specific listed result.

5. Salmonella from Flooded Kitchens

How floods spread it: Salmonella lives in the gut of poultry, pets and reptiles; floodwater carries it from droppings and wastewater into kitchens and food stores. Where it hides: fridges left without power, food shelves, chopping boards and kitchen floors. Symptoms and risk groups: diarrhoea, cramps, fever and nausea; children, older adults, pregnant women and people with weak immunity are most at risk. Prevention: discard flood-touched food and anything from a fridge that lost power for long, cook food thoroughly, and keep separate boards for raw and cooked food. According to WHD's product information, Salmonella is one of the organisms stated to be covered.

6. Hepatitis A Virus from Contaminated Water and Food

How floods spread it: hepatitis A spreads through food or water contaminated with faeces, a higher risk when water supplies may be affected. Where it hides: water containers, storage tanks, cups and kitchen surfaces. Symptoms and risk groups: tiredness, loss of appetite, nausea, upper right abdominal pain and yellow skin or eyes; adults usually show clearer symptoms than children. Prevention: drink clean water, wash hands before cooking, clean water tanks after the flood, and ask a doctor about vaccination. It belongs to the virus group the product says it covers in general; ask WHD for specific test data if needed.

7. Leptospira and Leptospirosis in Town

How floods spread it: rats in drains, markets and behind shops shed the bacteria in urine; it mixes into standing water and mud and enters through cuts, soaked skin, eyes, nose or mouth. Where it hides: damp mud in carports, front lawns, drains and shoes worn while wading. Symptoms and risk groups: sudden high fever, headache, calf pain and red eyes; parents who wade on the school run, waste collectors and people with foot wounds are most at risk. Prevention: wear boots, keep children out of puddles, cover wounds, wash feet with soap, and see a doctor for fever after wading. Leptospira is within the bacteria group the product says it covers in general, with no specific listed result.

8. Giardia lamblia, a Hardy Waterborne Parasite

How floods spread it: Giardia is a single-celled parasite that forms tough cysts and spreads through water and food contaminated with faeces. Children who play in puddles or swallow water by accident are at risk. Where it hides: water left in containers, garden puddles, storage tanks and soaked toys. Symptoms and risk groups: prolonged diarrhoea, bloating, greasy stools and weight loss; young children most of all. Prevention: drink boiled water, keep children out of standing water, empty containers and wash hands often. Parasites are not on WHD's listed organisms, and some parasite cysts resist common disinfectants, so clean water, washing and removing standing water are the main defences. Spraying is only a supporting surface step after cleaning.

9. Streptococcus pyogenes and Impetigo in Children

How floods spread it: children who play in water and get scrapes, mosquito bites or scratched skin let skin bacteria such as streptococci and staphylococci in, causing impetigo. Where it hides: towels, bedsheets, pillows and shared toys. Symptoms and risk groups: small blisters that burst and form honey-coloured crusts around the nose, mouth, arms and legs; it spreads easily among young children. Prevention: clean wounds, trim nails, use separate towels, and see a doctor if sores spread. It belongs to the bacteria group the product says it covers in general.

10. Household Mould: Cladosporium and Aspergillus

How floods spread it: when floors, lower walls, mattresses or rugs stay wet for more than 24 to 48 hours, airborne mould spores germinate and spread fast. Where it hides: behind wardrobes, under mattresses, bedroom wall corners, curtains, picture books and soft toys. Symptoms and risk groups: sneezing, stuffy nose, coughing, itchy rashes and asthma flare-ups; children with allergies or asthma and older adults are most affected. Prevention: dry the house fast, discard mouldy materials, scrub mould before disinfecting, and consider ozone treatment for musty closed rooms. According to WHD's service information, fungi are among the groups the spraying service is stated to cover.

How Cleaning and Spraying Work Together in Chai Nat Homes

WHO and the US CDC both advise removing mud and dirt from flood-contaminated surfaces first and then disinfecting. Items that cannot be cleaned, such as soft toys, sponges or soaked mattresses, should be thrown away, and homes should be dried within 24 to 48 hours to limit mould. Thailand's Department of Disease Control also warns about flood-related illness such as leptospirosis, diarrhoeal disease and skin infections.

According to WHD's product and service information, CHEMGENE HLD4H is stated to cover organisms including hand, foot and mouth disease virus, RSV, influenza H1N1 and H5N1, COVID-19, human coronavirus 229E, norovirus, Salmonella, Bordetella pertussis, mycobacteria, and bacteria and fungi in general, with the service page claiming 99.99%. Organisms not on that list, such as rotavirus, Shigella, hepatitis A, Leptospira or Streptococcus, should be treated as members of the bacteria or virus groups the product says it covers; ask WHD for organism-specific data. Parasites such as Giardia depend mainly on clean water and washing. Spraying is the final step after cleaning and drying, never a replacement for them or for medical care.

WHD's Post-Flood Spraying Process for Chai Nat Homes, Shops and Offices

According to the service information, WHD's trained technicians spray and/or ULV-fog (Ultra Low Volume fine mist) CHEMGENE HLD4H, a medical-grade UK disinfectant containing benzalkonium chloride and didecyldimethylammonium chloride. The service page cites the Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019. The usual steps:

1. Survey: send photos of each room, the flood line and the places children use most by phone or LINE.
2. Mud removal and washing first: discard soaked and damaged items, scrub floors and lower walls, wash plastic toys with soap and clean water, and open up the house to dry.
3. Zoning: separate the living room, children's bedroom, kitchen, bathroom and carport.
4. Everyone leaves the zone: children, older adults and pets leave; food, bottles, dishes and personal items are put away.
5. Spraying: floors, lower walls, furniture, touch points and hidden corners.
6. Re-entry: per the service information, wait about 30 minutes, following the technicians' timing on site, and wipe food-contact surfaces and items children mouth as advised.

WHD is based in Bang Khae, Bangkok 10160, with no branch in Chai Nat. Provincial jobs are arranged by phone and LINE according to the schedule, so book ahead. Pricing depends on size and condition. The service information lists a free CHEMGENE spray bottle and WELLGIENIC wet tissues, and tax invoices are available. Customers include hospitals, schools, malls, airports, offices, airlines, banks and residential buildings.
