Many people know Uthai Thani as a quiet town on the Sakae Krang River, but the 2026 flood has spread further than expected. According to the Department of Disaster Prevention and Mitigation (DDPM) report of 2 October 2026, eight districts were affected: Nong Chang, Huai Khot, Sawang Arom, Nong Khayang, Ban Rai, Lan Sak, Mueang Uthai Thani and Thap Than, covering 4,785 households, with the water level still rising. This article looks at the places the community uses together every day (morning markets, childcare centres, schools, temples, restaurants and raft houses), shows where mold, bacteria and viruses tend to hide once the water drops, and explains where a disinfection spraying service with CHEMGENE HLD4H fits into recovery.
A typical scenario (an illustrative example, not a review from any real customer)
Every morning from four o'clock, Auntie Boonma sets out seven or eight pots of curry on a wooden stall at the morning market in Nong Chang. Her regulars are farmers heading out to the fields, teachers picking up lunch, and parents buying rice and curry in bags for their children to eat at the childcare centre. She has sold there for almost twenty years, and her three-year-old grandson has grown up to the sound of the market at dawn.
In late September it rained hard for days. Water started to back up into the market through the drain at the rear. By the third day the lower row of stalls was half submerged, and ice buckets, chopping boards and basins floated in cloudy water that smelled of sewers. The market closed. Auntie Boonma carried her pots home, and the childcare centre her grandson attends closed too, because water had entered the children's nap room.
Her worry is not how long she will be out of business. It is that when she reopens, someone might eat her curry and get diarrhoea even though she cooks as cleanly as ever, because the stalls, the floor and the drain beneath them have just spent days soaking in sewage-tainted water. She also worries about her grandson. If the centre reopens and the whole class catches hand, foot and mouth disease or a stomach bug, she will have to close the stall again to look after him. Her question is simple: "Once we've washed everything, what else do we need to do to be sure?"
The DDPM situation report of 2 October 2026 listed eight affected districts in Uthai Thani and 4,785 households, with the water level rising. The trend was reported for the province as a whole, not district by district, so the status below is the provincial trend on that day. Figures change daily; please follow the latest provincial and district announcements.
On the same day the DDPM reported flooding nationwide in 31 provinces plus Bangkok, affecting 1,245,581 households and 3,535,206 people, caused by heavy to very heavy rain together with runoff from the north.
The district list reflects the province's varied terrain: the provincial seat on the Sakae Krang River with its row of raft houses; farming plains in Nong Chang, Thap Than, Sawang Arom and Nong Khayang; and the western districts of Ban Rai, Lan Sak and Huai Khot with foothills and large forests. Water from the hills tends to move fast and carry a lot of silt, while water on the plains and along the river tends to linger. Each leaves a different germ and moisture problem behind.
In a small province like Uthai Thani, daily life revolves around a handful of places: the market in the morning, the childcare centre or school, the temple on holy days, the noodle shop near the district office in the evening. When these places flood, the whole sub-district comes back to them at once as soon as the water drops, which is why they should be disinfected systematically first.
Four features of the province matter here. First, morning markets are the food hub of almost every district, with cooked food and fresh produce displayed close to floors and drains. Second, childcare centres and sub-district schools are where small children spend most of the day, nap on the floor and share toys. Third, raft houses and riverside homes on the Sakae Krang sit beside the water all the time, and their wooden floors and walls absorb moisture easily. Fourth, farmsteads in the western districts keep animals, cattle pens and feed stores, which attract rats and add germs from animal waste.
Understanding how people in Uthai Thani share space makes it easier to get the recovery order right: not washing everywhere the same way, but tackling the riskiest spots first with the method that suits each one.
Floods bring many kinds of germs at once, but each group prefers different places. Knowing where they hide tells you where to disinfect first.
Drains under stalls, market floors and soaked chopping boards harbour E. coli and other faecal bacteria from wastewater, as well as Salmonella from animal droppings and raw meat. On a vendor's hands, utensils or food, they cause diarrhoea, cramps, fever and food poisoning. Markets that serve cooked food to large numbers of people each morning come first.
Norovirus and rotavirus cause sudden vomiting and diarrhoea in young children, survive a long time on hard surfaces and spread easily by hand. Hand, foot and mouth disease passes through toys, tables, rails and saliva. RSV and influenza spread readily in rooms where children nap close together, and cool, damp post-rain weather raises the odds of illness.
Wooden halls, storerooms full of mats and blankets, book cabinets and soaked ceiling boards are where mold thrives. It can start growing within a day or two of materials getting wet and staying wet, according to general public-health guidance, and it releases airborne spores that trigger allergies, asthma and lingering coughs, especially among the older people who visit temples regularly.
Leptospira, the cause of leptospirosis, comes from the urine of rats and other animals and lingers in standing water and mud, particularly around pens, feed stores and the open ground beneath houses in farming districts. It enters through cuts and mucous membranes, so anyone clearing mud should always wear boots and gloves.
Drain smells, rotting mud and mustiness come from leftover organic matter and active microbes. They keep diners away from restaurants and make parents hesitate to send children back to the childcare centre.
Children under five, older people, pregnant women, people with diabetes, kidney or lung disease, and anyone with cuts on their hands or feet need the most care. If someone has a high fever, muscle pain (especially in the calves), red eyes, nonstop diarrhoea, vomiting that stops them eating, mouth sores with spots on the hands and feet, or fast breathing, see a doctor immediately and mention flood exposure. Spraying looks after places. It does not treat people.
Health. When one child at a childcare centre falls ill, several more usually follow within days, and the germs travel home to siblings and grandparents. In a market, if someone gets diarrhoea after eating from one stall, word spreads through the district in a single day.
Income. A vendor who has already lost a week to the flood cannot afford to lose another because customers stay away. Restaurants closed by sick staff and homestays losing bookings over musty rooms all suffer a second loss.
Time. A childcare centre that closes again because of an outbreak forces parents who farm or work for daily wages to stay home, and puts more childcare on grandparents.
Community trust. Where almost everyone knows everyone, the reputation of a stall, shop or childcare centre matters enormously. Being able to say clearly "we washed and we disinfected" brings people back sooner.
Repeat repairs. Untreated mold comes back under new paint, wooden walls rot faster, and childcare items like nap mattresses need replacing sooner than they should.
1. "The sun is strong now, so the germs are dead." Sunlight helps things dry and reduces germs on surfaces it hits directly, but the undersides of stalls, children's nap rooms, the backs of cabinets and gaps in wooden floors never see the sun.
2. "A powerful hose is enough." Hosing removes mud but does not disinfect, and the spray can splash germs onto walls and higher objects.
3. "Stronger bleach is better." Too strong a solution stings the nose and irritates skin, especially in small children. Mixing it with some toilet cleaners can release dangerous gas, and it still misses places you cannot see.
4. "A fresh coat of paint finishes the job." Mold under paint comes back with its smell, and the work has to be redone within months.
5. "No smell means no germs." Many viruses and bacteria have no smell. A room that smells better thanks to air freshener or open windows does not have germ-free surfaces.
World Health Disinfection (WHD) is based in Bang Khae, Bangkok, and has no branch in Uthai Thani. People in the province can contact the team to plan a job, but coverage, travel and dates must be confirmed by phone on 065-556-6294 or LINE @whd268 beforehand, and same-day arrival cannot be guaranteed.
According to the service information, trained technicians use spraying and/or ULV (Ultra Low Volume) fine-mist fogging with CHEMGENE HLD4H, a medical-grade disinfectant from the United Kingdom containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. The service page lists viruses, bacteria and fungi, including COVID-19, RSV, H1N1, H5N1 and hand, foot and mouth virus, at a claimed 99.99%, and lists approvals or endorsements from Thailand's Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019.
Mud and grease act like a shield around germs. Disinfectant sprayed onto mud binds to the mud instead of reaching the germs, so the surface must be cleaned first. Once it is clean, spraying coats the surfaces hands touch most: stalls, counters, rails, toilet doors, children's dining tables and the lower walls that were under water. ULV fogging turns the disinfectant into a very fine mist that drifts and settles on hard-to-reach surfaces such as the undersides of toy shelves, behind mattress cupboards, the gaps between raft-house floorboards and market roof frames. The two methods can be combined.
Spraying comes after washing and drying. It does not replace cleaning, and you should not assume it leaves no residue at all. In closed rooms that still smell musty, such as nap rooms or raft-house bedrooms, residential ozone disinfection can be added. According to the service information, WHD's customers include hospitals, schools, malls, airports, offices, airlines, banks and residential buildings. A promotion includes a free CHEMGENE spray bottle and WELLGIENIC wet tissues, and a tax invoice is available.
Morning markets. Markets in Nong Chang, Thap Than and town usually wind down between late morning and noon, so the afternoon is the time to clear drains, scrub stalls and spray, leaving the waiting and airing time complete before vendors arrive at four in the morning. Start with fresh food and cooked food sections, shared toilets and washing-up points.
Childcare centres and schools. Spray at least a day or two before reopening. Prioritise nap rooms, children's toilets, toy corners, canteens and stair rails. Wash or replace fabric toys and nap mats; wash plastic toys and let them dry first, then wipe anything children put in their mouths after spraying, as the technicians advise.
Temples and halls. If the temple served as a shelter, spray the hall, shared toilets and kitchen before the next holy day or ceremony, so older regulars can use the space safely.
Raft houses and Sakae Krang riverside homes. Dry wooden floors and walls as much as possible first. ULV is especially useful for gaps between boards. Arrange for everyone on the raft to wait on shore during spraying.
Restaurants, shops and homestays. Book on a closing day or before guests arrive, focusing on kitchens, toilets, guest rooms and dining areas.
Farmsteads in Ban Rai, Lan Sak and Huai Khot. Separate the living area clearly from animal pens. Clear manure and mud and deal with rats first. Spraying inside the house reduces germs on surfaces the family touches.
An illustrative example to explain the process, not a review or the words of a real person
Imagine a childcare centre in Sawang Arom caring for about forty children aged two to five. It is a single-storey building with two classrooms, a nap room, children's toilets and a small kitchen. Water came in about a hand-span deep and stayed for several days. When it receded, the head teacher (call her Teacher Ann for this example) found every nap mat soaked, the wooden toy shelves swollen, a tide line on the walls and an unmistakable musty smell in the nap room.
Teacher Ann and volunteer parents threw out wet mats and pillows, washed blankets in hot water, set aside fabric toys that could not be washed, scrubbed plastic toys with soapy water and dried them in the sun, shovelled out mud and scrubbed floors, walls and toilets. They left every door and window open for three days until the floor was dry. Then they sent photos of each room to WHD on LINE. The team confirmed a date based on road conditions and asked them to store the washed toys in closed boxes outside during spraying.
On the day, technicians sprayed the floors, lower walls, dining tables, washbasins and child-size toilets, then used ULV in the nap room and classrooms so the mist reached under shelves, corners and the backs of cupboards. Teachers and parents waited outside. When the waiting time was up and the technicians gave the all-clear, Teacher Ann opened the windows, wiped the dining tables and basins again and brought the toys back. The centre posted in the parents' group what had been done and asked parents to watch for fever, mouth sores or diarrhoea, to see a doctor if they appeared and to keep the child home for a while. The realistic outcome is cleaner rooms, less mustiness and more confident parents, not a guarantee that no child will ever get sick.
Does WHD have a branch in Uthai Thani?
No. WHD is in Bang Khae, Bangkok. Plan a job in Uthai Thani on 065-556-6294 or LINE @whd268. Coverage, travel and dates are confirmed job by job, and same-day arrival is not guaranteed.
Is spraying a childcare centre safe?
Children, staff and pets must be outside during spraying. Per the service information, wait about 30 minutes and re-enter when the technicians say so, then ventilate and wipe anything children put in their mouths as advised. Book at least a day before children return.
How long does a market need to close?
It depends on the size of the market and its condition after washing. Spraying can usually be booked for the afternoon after the market closes; the team estimates timing from your photos.
The water has not dropped yet. What should we do first?
You can plan ahead now, but spraying must wait until the water is gone and mud has been cleared and washed. In the meantime, put safety first and avoid wading unless necessary.
After spraying, can we stop worrying about leptospirosis?
No. Spraying reduces germs on indoor surfaces, but wading and mud outside are still a risk. Wear boots, cover cuts and see a doctor at once for fever, calf pain or red eyes after exposure.
Does the disinfectant leave a smell or residue?
Do not assume there is no residue at all. Follow the technicians' advice on ventilation and on wiping food-contact surfaces afterwards.
Send photos, your district and the type of site. The team will assess it and confirm a feasible date.
