For many families in Kham Khuean Kaeo District and Pa Tio District, Yasothon Province, the hard work starts when the water goes down. According to the Department of Disaster Prevention and Mitigation (DDPM), data as of 06:00 on 2 October 2026, flooding in these two districts covered 5 subdistricts, 12 villages and 243 households, and water levels were falling. What stays behind once the water retreats is mud, damp floors and walls, bacteria, mold and a stubborn musty smell. This guide helps Yasothon families understand what a flood leaves in the home, how to restore a house in the right order, and when ozone disinfection in Yasothon fits, so the house becomes healthy again for every generation living in it.
According to the DDPM report for 06:00 on 2 October 2026, published by Bangkokbiznews, the situation in Yasothon was:
The report does not break the figures down by subdistrict, give water depths, or say how long each village was under water. This article therefore uses only the combined figures for the two districts as reported, and does not guess at any others.
Nationally, the DDPM reported at 06:00 on 5 October 2026, via Daily News, that 26 provinces plus Bangkok were still affected, totalling 1,270,151 households or 3,519,416 people. The Office of the National Water Resources (ONWR) also warned of heavy rain and flash floods from 5 to 7 October 2026 in the north and parts of the south, according to Thai PBS.
Note: all figures are as of the dates in the reports and change daily. Follow the latest notices from the district office, local administration and the DDPM.
This is an example case based on situations commonly seen in rural villages after floods. It does not describe any particular home in Kham Khuean Kaeo or Pa Tio.
Grandpa Boonmee and Grandma Khampun live in the raised wooden house they built as a young couple. Their children work in other provinces, so only a grandson in primary school lives with them. The open space under the house holds a bamboo platform, hoes and spades, fertiliser sacks and a few chickens. Beside the house is a small rice barn with the grain they eat all year. When the water rose, the three of them carried everything upstairs and lived on the upper floor until it fell.
Once it receded, the ground under the house was slick, sticky mud. The bamboo platform was stained black, the timber storeroom on the lower level was damp, and a musty smell began drifting up to the bedroom. The grandson started coughing at night. Grandma complained of a rash on her legs after wading to shovel mud. Grandpa worried the damp would turn the stored rice moldy. A relative in Yasothon town phoned to ask what to do first, and whether anything would really get rid of the smell.
Questions like these come up wherever water has just receded. The DDPM's figure of 243 households may look small next to other provinces, but for each family that house is everything. Restoring it in the right order from day one saves money, time and health in the long run.
Yasothon is a farming province in the Chi river basin. Most people grow rice, and many villages still have traditional raised Isan wooden houses alongside newer single-storey concrete homes. Each type handles water differently and leaves different problems behind.
Shared village buildings such as temple halls, community halls, primary schools and childcare centres may also need thorough cleaning, since many people, especially children and older adults, use them every day. Getting them clean and dry before reopening helps limit the spread of illness across the community.
The receding phase is when several risks rise together: people move back, shovel mud and touch contaminated water and soil while the house is still damp, and mold starts growing fast. Knowing which germs come with floodwater helps people protect themselves properly.
Thailand's Department of Disease Control and the CDC agree that floodwater is dirtier than it looks and carries several groups of germs into the home.
E. coli comes from human and animal faeces in floodwater. If hands that touched mud then touch food or the mouth, it can cause diarrhoea, cramps, nausea and vomiting. Salmonella is found on contaminated food and utensils and causes food poisoning, especially when a flooded kitchen's plates and pots are used before being properly washed. Leptospira causes leptospirosis, common in rice-farming areas. It enters through cuts and skin soaked in water for a long time. Anyone who waded or shovelled mud and then develops sudden high fever, headache, muscle pain especially in the calves, or red eyes should go to a hospital or subdistrict health centre quickly and tell staff about the wading.
Norovirus and rotavirus cause diarrhoea and vomiting and spread through hands, surfaces and contaminated food. Small children are at particular risk because they can dehydrate quickly. High humidity and crowds of people helping clean the village also favour respiratory viruses such as RSV, dangerous for infants and older adults, and influenza, which peaks in the rainy season.
The World Health Organization (WHO) and the CDC advise cleaning and drying a home within 24 to 48 hours of the water receding, because mold starts to grow on damp materials in that window: mats, mattresses, pillows, blankets, wooden cabinets, floorboards and plaster. Mold causes allergies, sneezing, a blocked nose, coughing and eye and skin irritation, and can trigger asthma attacks.
Odour that lingers after the water drops is a sign of remaining moisture, rotting organic matter or growing mold. Perfume, powder or incense to cover it does nothing about the cause.
Older adults, small children, pregnant women and people with chronic conditions such as diabetes, high blood pressure, kidney or lung disease need extra care. Where possible, they should return after the house has been cleaned and dried. Whoever does the cleaning should wear boots, rubber gloves and a mask, and wash hands with soap before every meal.
Health: coughs, allergies, rashes and diarrhoea often follow a flood. If the house stays damp and moldy, symptoms can drag on for weeks, and grandparents and children fall ill more often.
Cost: farming families carry both crop losses and home repairs. Swollen plywood furniture, mattresses and appliances may need replacing, and if mold reaches the timber frame, repair bills climb further.
Time: after the water goes, everyone splits their days between cleaning, the paddies and returning to work. Incomplete cleaning means doing it all again.
Community: in villages where people visit each other, gather at the temple and send children to the same school, germs lingering in several houses spread easily between them.
Peace of mind: older people living alone with grandchildren are often exhausted after a flood. Knowing the house is clean and no longer musty helps them sleep and start again sooner.
Washed but not dried: many families wash out every trace of mud, but water soaked into timber and plaster remains. With humid air and passing showers, mold returns within days.
Disinfectant on visible surfaces only: it helps on smooth surfaces but does not reach room air, the space under floorboards, behind cabinets or inside curtain fabric. Never mix bleach with ammonia or other products.
Airing and fans: useful up to a point, but rainy-season humidity slows drying, and fans spread mold spores around.
Perfume or incense: feels better briefly but leaves the source untouched.
Painting or papering over mold: mold keeps growing underneath and returns as black spots or bubbling paint.
Each method has its place, but none deals with germs and odour in the air and unreachable corners. That gap is what residential ozone disinfection fills, once the house is clean and dry.
Ozone (O3) is a form of oxygen with three atoms and strong oxidising power. Released in a sealed, unoccupied room, it spreads evenly, reaching the air, corners and surfaces hands cannot reach. It breaks down bacteria, viruses and mold spores and the molecules that cause odour, then returns to oxygen (O2), leaving no chemical residue.
According to test results certified for the company by Thailand's Department of Medical Sciences and Intertek (UK), the ozone system used by World Health Disinfection (WHD) eliminates viruses, bacteria and mold at 99.99%. The documents are on the certification page, and equipment details are on the ozone machine page.
Remember: ozone is used only in closed, empty rooms. No people, pets or plants inside during treatment; return only after the rest and ventilation period set by the technician. Ozone comes after mud removal, washing and drying. It does not replace cleaning, repairs or seeing a doctor.
WHD is based in Bang Khae, Bangkok 10160, with no branch in Yasothon. Families in Kham Khuean Kaeo, Pa Tio and neighbouring districts can call 065-556-6294 or add LINE @whd268 to plan a job. The team confirms travel, coverage and a suitable appointment when you get in touch; same-day arrival cannot be promised. Ozone jobs of 15,000 baht or more come with a free medical-grade disinfectant spray under the company promotion, which may suit several houses in one extended family or a shared community building.
The DDPM's 2 October report says water in both districts was falling, so many families are now beginning the clean-up. The correct order is: remove mud, wash with clean water and detergent, dry the house, then treat with ozone. Treating while mud remains or floors are still wet gives poor results, because the source of germs and smell is still there.
In early October 2026 the ONWR was still warning of heavy rain in some regions. Its 5 to 7 October alert focused on the north and parts of the south, but Yasothon families should keep following the forecast and district announcements. If unsure whether water could return, clean and dry first and book ozone once conditions settle.
In homes with older relatives or small children, consider treating the bedroom first so there is a clean, fresh room to rest in, then the storeroom, under-house area or rice barn in a later round.
Results vary with the condition of the house and preparation. Soaked items such as mattresses or swollen plywood should be replaced.
This example case explains the process; it is not a review from a real customer.
Nid, the eldest daughter, works in another province. When she heard her parents' village in Kham Khuean Kaeo had flooded, she took leave and arrived as the water began to fall. The family shovelled mud from under the house, washed the posts and floorboards, threw out soaked mats and mattresses, washed the kitchen pots and plates in clean water, and kept the house open to the breeze for several days.
The house looked clean, yet her five-year-old son still coughed every night and her father said the bedroom smelled of wet earth. Nid called WHD, described the house and sent photos on LINE. The team asked whether the timber and walls were fully dry, advised waiting until they were, then confirmed travel to Yasothon and a date that suited both sides.
On the day, the team worked in three parts: the upstairs bedroom, the hall and kitchen, and the walled storeroom under the house. The family waited at a relative's home, and the chickens were moved away from the treated area. After the contact time and rest period, the technician opened the windows to ventilate before the family returned. Nid noticed the bedroom no longer smelled of wet soil and her son slept better. Even so, she took him to the hospital for a check-up as the team suggested, because a lasting cough should always be assessed by a doctor.
Moisture is still trapped in timber, plaster, fabric and corners, and mold has started to grow. The smell fades once the house is truly dry and the germ sources are dealt with; ozone after washing and drying helps.
No. WHD is based in Bang Khae, Bangkok. Customers in Kham Khuean Kaeo and Pa Tio can call 065-556-6294 or LINE @whd268; travel and coverage are confirmed when you contact us.
No. In wooden houses air passes between floors through the boards, so everyone should leave the house and return after the rest and ventilation period.
Yes. Mud removal, washing and drying always come first; ozone handles the germs and odour left over.
Do not rely on ozone to rescue flood-soaked or moldy rice. Sort it and consult agricultural or health officers. An empty rice barn can be considered for treatment.
See a doctor or the subdistrict health centre quickly and mention the floodwater, especially with calf pain or high fever, which may point to leptospirosis. Ozone at home is never a substitute for treatment.
