A Carer in Kham Khuean Kaeo and Thirty Nap Mats

A typical scenario based on situations that commonly happen. It is used to explain the problem and does not describe a real person.

Kru Saengduean is a carer at a subdistrict child development centre in Kham Khuean Kaeo. The centre looks after about thirty children aged two to four. Every morning parents drop off their children before heading to the fields or to work in town. On the night of the heavy rain, water flowed from low ground around the village into the centre's single-storey building, high enough to soak the nap mats laid out on the floor, the toy shelves and the cupboard where the children's cups are kept.

After the water receded, Kru Saengduean, subdistrict staff and parents shovelled out the mud, carried the wet mats out to dry, washed plastic toys in tubs and scrubbed the floor until the tiles showed again. Then new problems appeared. Mats dried in the sun for three days still smelled musty because the foam inside was damp. The lower walls showed a tide line. Several parents said they would keep their children home until they were sure, because they had heard of hand-foot-and-mouth cases in another village.

What Kru Saengduean needed was not just visible cleanliness but an answer she could give parents about what had been done and whether it was complete. The same question comes up at the women's group rice-packing house, the pillow shop where customers browse, the temple hall and the homestay expecting guests next month.

Flooded Areas in Yasothon According to the DDPM Report of 2 October 2026

The data in the table comes from the DDPM report as published in the media. Figures change daily; check the latest situation with the district office, subdistrict administrative organisation, municipality or the Yasothon provincial DDPM office.

Kham Khuean Kaeo lies south of Yasothon town and has a district-town centre with markets, shops and government offices, surrounded by farming villages. Pa Tio is known for villages that make mon khit and triangular cushions sold all over Thailand, especially Ban Si Than. Both districts therefore have many kinds of shared places, from child centres and schools to community production workshops and shops that serve customers from outside the area.

Nationally, DDPM reported on 2 October 2026 that 31 provinces plus Bangkok were flooded, with 1,245,581 households and 3,535,206 people affected by heavy to very heavy rain and runoff from the North. Yasothon is one of the Northeastern provinces in that report, and the period after the water recedes is when systematic recovery must begin.

What the Yasothon Flood Brought In: Many Germs, Mold and Musty Odour

The water that entered communities in Kham Khuean Kaeo and Pa Tio flowed through rice paddies, grain-drying yards, animal pens, pit latrines and village drains first. It brought several groups of microbes at once, each dangerous over a different time frame.

Bacteria Behind Diarrhoea and Leptospirosis

E. coli and other faecal bacteria tell us the water carried sewage from latrines and animal pens. When they sit on tables, floors, utensils or hands and reach the mouth, they cause diarrhoea, stomach pain and vomiting, which is especially dangerous for young children who dehydrate quickly. Salmonella spreads through food and food-prep surfaces, so it is a risk for kitchens, restaurants and community food-processing rooms. Leptospira, the cause of leptospirosis, lives in water and mud contaminated with rat urine. People who clean up or return to check their fields without boots are most at risk. Anyone with high fever, headache, severe calf pain or red eyes after wading needs to see a doctor quickly.

Viruses Child Centres and Schools Must Watch

Hand-foot-and-mouth disease is what parents fear most, because young children constantly put toys and hands in their mouths. Rotavirus and norovirus cause heavy diarrhoea and vomiting and can spread through a whole room within days. RSV can make small children struggle to breathe, and influenza spreads easily among adults working close together, such as community-enterprise members sharing one workshop.

Mold and the Materials Yasothon Uses Every Day

Yasothon homes and workshops are full of absorbent materials: kapok in pillows and mattresses, cotton and handwoven cloth, reed mats, timber and sacks. If they are not dried within the 24 to 48 hours that WHO and the US CDC advise, mold starts to grow. Wet kapok inside a pillow is almost impossible to dry right through, so it is better discarded than kept. Mold on walls and wood releases spores that trouble people with allergies, asthma and older relatives, and creates the musty odour that customers and guests notice the moment they walk in.

Risk Map: Shared Places in Kham Khuean Kaeo and Pa Tio

What these places share is that people from many households use them. If the 243 affected households in the two districts use the same child centre, market and temple, restoring those shared places properly protects more people than working house by house.

Hidden Damage to Yasothon Communities When Disinfection Is Skipped

Several young children fall ill at once. A child centre that reopens too early without disinfection may face a hand-foot-and-mouth or diarrhoea outbreak and have to close again. Parents lose working days, and lost trust takes a long time to rebuild.

Community products lose their name. Rice packed in a room that still smells musty, or pillows that reach customers with mold spots, can lead shops and online buyers to cancel orders. A group that spent years building its brand can lose regular customers in one round.

Homestay reviews suffer. Guests who come to experience village life remember a musty bedroom longer than a good meal, and online reviews stay up for a long time.

Labour and time are spent twice. Hand-wiping big spaces like mills, storerooms or temple halls takes people days, and when mold returns the work starts again, just as members need to get back to their fields.

Older relatives pay a higher price. Many Yasothon families have grandparents at home looking after grandchildren while the parents work. Older people with diabetes, heart or lung conditions react more strongly to mold spores and to gut infections than working-age adults, and a bout of diarrhoea that a young adult shrugs off can leave an older person dehydrated and in hospital. Restoring the home and the shared places they visit, such as the temple and the market, protects them as well.

Why Washing Alone Is Not Enough for Shared Places in Yasothon

• Water and detergent remove dirt but do not disinfect. It is a necessary step, but many germs remain on surfaces afterwards.
• Cloths cannot reach every spot: under sack racks, behind machines, between pillow display slats and around children's table legs.
• Home-mixed bleach can be ineffective or dangerous. The wrong concentration may not disinfect or may sting eyes and noses, and it must never be mixed with other toilet cleaners because toxic gases can form.
• Air fresheners and incense mask the musty smell for a while, but the mold and moisture remain.
• Painting over mold just hides it until black spots return within months if the wall is still damp.

None of this means washing is unimportant. Shovelling mud, washing, discarding damaged items and drying are the core work and always come first. Spraying is the next step that treats every surface in the area.

WHD Disinfection Spraying in Yasothon: Principle, Disinfectant and Process

World Health Disinfection (WHD) provides a disinfection spraying service carried out by trained technicians. According to the service information, technicians use both direct spraying and ULV (Ultra Low Volume) fogging, which turns the disinfectant into a very fine mist.

How the Mist Reaches Surfaces After Cleaning

Once a space has been washed and is drying, the ULV mist spreads through the room, drifting into gaps between shelves, under tables, behind machines and around complicated shapes, then settling on surfaces in a thin, even layer. Unlike wiping, it does not depend on where someone's hand happens to reach. Direct spraying is used where a clear wet coat is needed, such as bathroom floors, counters and worktables. The disinfectant needs time on the surface to work fully, which is why everyone waits about 30 minutes before going back in.

CHEMGENE HLD4H

The disinfectant is CHEMGENE HLD4H, a medical-grade disinfectant from the United Kingdom containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. According to the service information it covers viruses, bacteria and fungi, including COVID-19, RSV, H1N1, H5N1 and hand-foot-and-mouth virus, with a stated efficacy of 99.99%. The service page cites approvals and endorsements from Thailand's Department of Medical Sciences, Mahidol University, NHS England and the EN 14476:2013+A2:2019 standard, and lists customers including hospitals, schools, malls, airports, offices, airlines, banks and residential buildings.

4. Mist reaches what hands miss: under sack racks, behind machines and around little table legs.
5. Help keep mold from returning when combined with fully drying walls and timber.
6. Get homestays guest-ready: a bedroom without a musty smell earns good reviews.
7. Save members' labour while they need to tend their fields.
8. Short wait: about 30 minutes, or as advised.
9. Tax invoices and follow-up tools: a spray bottle and wet tissues for daily touch points.

Before and After: A Child Development Centre in Kham Khuean Kaeo

Example Case: A Community Enterprise Rice-Packing House in Pa Tio

An example case to explain the process. It is not a verified customer review.

A women's group in a Pa Tio subdistrict runs a community enterprise that mills rice from members' fields, vacuum-packs it and sells to shops and online customers. Their single-storey building has a milling room, a sorting and packing room and a finished-goods store. When water rose to about mid-shin, some paddy sacks on low pallets got wet and the stacked cardboard boxes in the corner fell apart.

Khun Malai, the group's chair, decided at once that all flood-soaked rice must be separated and not sold, and the ruined boxes thrown away. After the water went down, members shovelled mud, washed floors and pallets, wiped the scales and sealing machine and kept the doors open for days. Yet the store still smelled musty, and grey-green mold spots appeared in the corners. Khun Malai worried that packing a new batch in that room might let the smell reach the product, disappointing customers who buy community rice because they trust its cleanliness.

She contacted WHD on LINE with photos of every room. The team advised scraping and washing off visible mold first, moving every sack, bag and label out of the building, and removing detachable parts that touch rice directly for separate washing. On a date confirmed in advance around the travel schedule, technicians treated the milling, packing and storage rooms one at a time, with ULV in rooms that could be closed and direct spraying on floors and pallets. Members waited outside for about 30 minutes as instructed, then ventilated, rinsed rice-contact surfaces with clean water as advised and let everything dry before packing a new batch.

Because the group sells certified rice, Khun Malai also asked its certification body how to record the use of disinfectant on the building structure, something any certified group should always do. Members now wipe handles, scales and the packing table with the spray bottle and wet tissues every morning and check the wall corners weekly.

Yasothon Flood Recovery Checklist

Before Spraying

• Cut power to flooded sections and have electrics, rice mills and machines checked before restarting.
• Wear boots, gloves and a mask, and cover cuts before cleaning.
• Shovel mud and wash floors, walls and pallets with detergent.
• Discard flooded rice, food, medicine, kapok pillows, mattresses and cardboard.
• Launder usable sheets, curtains and woven cloth and dry them completely.
• Move stock, packaging, documents and Buddha images out of the zone to be sprayed.
• Open doors and windows and run fans to dry the building as fast as possible.
• Photograph the damage for assistance claims with the subdistrict or district office.

After Spraying

• Wait about 30 minutes or as advised, then ventilate.
• Rinse or wipe food, rice and toy surfaces as instructed.
• Wipe frequent touch points daily with the spray bottle and wet tissues.
• Check for mold weekly and find the moisture source if it returns.
• Anyone with fever, calf pain or severe diarrhoea should see a doctor.
• For closed homestay bedrooms that still smell musty, consider the ozone disinfection service as an add-on.

FAQ: Flood Disinfection Spraying in Yasothon

Can WHD serve Kham Khuean Kaeo and Pa Tio?

Contact the team on 065-556-6294 or LINE @whd268 to plan. WHD is based in Bang Khae, Bangkok, with no branch in Yasothon. The team will confirm a travel date; same-day arrival cannot be guaranteed.

Can a rice-packing house be sprayed without affecting the rice?

Only the building and equipment are sprayed, after all rice and packaging have been removed. Never spray rice or food. Rice-contact surfaces must be rinsed as advised, and certified groups should also check with their certification body.

Can flood-soaked pillows be sprayed and sold?

Not recommended. Wet kapok and foam are very hard to dry right through, and spraying treats surfaces, not pillow filling. Wet stock should be pulled.

Can spraying replace mud removal?

No. Mud must always be removed and surfaces washed first, because the disinfectant only works well on clean surfaces. Spraying is the step that follows cleaning and drying, not a shortcut around them.

Can several places in one village be done on the same trip?

Yes, and it is often the sensible way to plan. A child centre, temple hall and community workshop in the same subdistrict can be scheduled together so the team travels once. Tell the team about every site when you first make contact.

Do we have to leave during spraying?

Yes, everyone including children, older people and pets. Return when the technicians say, usually after about 30 minutes.

Will there be no residue at all?

Do not assume so. Food-contact surfaces and children's toys should be wiped or rinsed as advised before use.

What if someone is ill after the flood?

See a doctor first, especially for children weak from diarrhoea or vomiting and adults with fever or calf pain after wading. Spraying reduces environmental germs; it is not medical treatment.
