A typical scenario: a temple sala in Prakhon Chai after a week as a community kitchen

Picture a village temple in Prakhon Chai (an example case) on ground slightly higher than the homes around it. When water spread over the rice fields and village roads, the sala hall became a shelter for several families. The temple kitchen cooked rice and curries for everyone each day. Mats, mattresses, blankets and relief bags covered the floor; children played on the boards, older people rested in the corners, and the temple toilets were used many times more than usual.

Late in the week, water crept into the temple grounds and up to the sala steps, flooding the lower kitchen floor. When it receded, villagers went home and left behind damp mats and mattresses, food scraps, mud in the kitchen, toilets with a strong smell, and several children with diarrhoea and fever. Within days, black spots appeared on the kitchen walls and wooden door frames.

The temple committee knows an annual merit-making festival is coming, when people from several villages will gather in the same sala. Their question is not just how to clean it, but how to make a hall and kitchen that hundreds will use safe enough. Head teachers, shop owners and market vendors in Nang Rong and Prakhon Chai are asking the same.

Note: this is a typical scenario based on common post-flood situations and does not describe any real temple or person.

Flooded areas in Buriram according to DDPM

According to the DDPM report of 2 October 2026, two districts of Buriram were affected:

These figures are for 2 October 2026 and change daily, so follow provincial, district and subdistrict announcements before planning recovery. Nationally, DDPM reported the same day that floods affected 31 provinces plus Bangkok, 1,245,581 households and 3,535,206 people, caused by heavy to very heavy rain and runoff.

Nang Rong is the trading hub of southern Buriram, with markets, wholesalers, restaurants and offices serving people from surrounding districts. Prakhon Chai combines rice-farming villages with historic sites such as Prasat Mueang Tam. Recovery therefore involves homes and the places many people share.

Why Nang Rong and Prakhon Chai should spray shared places

Rural Isan life revolves around shared spaces: one temple, one child centre, one morning market. During a flood these become the most crowded places of all. If a home is clean but the sala or classroom still carries germs, family members bring them back. Places to plan for:

• Temples, sala halls and temple kitchens: many just served as shelters and central kitchens, with crowds sharing toilets and floors for days.
• Fresh markets and weekly markets in Nang Rong: meat, fish, vegetable and cooked-food stalls and their drains collect mud and organic waste.
• Shophouses, wholesalers and grocery stores: storerooms where water reached the floor are full of wet cardboard and musty air.
• Noodle shops, som tam stalls and made-to-order kitchens: small businesses that need to reopen fast for daily income.
• Schools and child development centres: young children are most exposed to hand-foot-mouth disease, gut viruses and RSV.
• District offices, subdistrict offices and health promoting hospitals: where people seek aid, collect medicine and file documents.
• Weaving groups and community learning centres: buildings with looms, silk yarn and woven cloth are highly prone to mold when damp.
• Shops and lodging near tourist sites in Prakhon Chai: ready to welcome visitors again when travel returns to normal.

Our earlier ozone article for Buriram focused on stilt houses, rice stores and closed rooms. This one focuses on large spaces and surfaces many people touch, where spraying gives better coverage.

The many germs after the Buriram floods that farmers, children and older people should know about

Floodwater in Nang Rong and Prakhon Chai ran through rice fields, cattle and buffalo pens, chicken coops, septic tanks and village roads before entering homes, temples and markets. It carried several groups of germs, not just mud.

Bacteria

• E. coli and faecal bacteria from people and animals: contaminate floors, water jars, dishes and food, causing diarrhoea, cramps and vomiting; small children and older adults dehydrate quickly.
• Salmonella: found in contaminated water and poorly stored food, such as large batches cooked at shelters and left out too long.
• Leptospira (leptospirosis risk): rice farmers wading through fields and village streets are a key risk group. It enters through cuts or soaked skin; watch for sudden high fever, severe calf pain and red eyes.
• Melioidosis bacteria: live in soil and water in Isan. People in direct contact with mud, especially those with diabetes, are at risk. Persistent fever, cough or abscesses call for a doctor, mentioning the mud and water exposure.

Viruses

• Norovirus and rotavirus: spread fast in shelters, sala halls and schools via hands, cutlery, taps and door handles.
• Hand-foot-mouth disease virus: common in child centres, spread through toys, mats and tables.
• RSV and influenza: nights sleeping together in a damp sala help respiratory viruses spread.

Mold and spores

Mold can start growing on wet materials within about one to two days, which is why CDC and the World Health Organization advise cleaning and drying within 24 to 48 hours. In Buriram, mold favourites include reed mats, mattresses, blankets, rice sacks, silk yarn, woven cloth, wooden house walls and cardboard boxes in shops. Airborne spores trigger allergies, asthma and lingering coughs.

Musty and drain odours

A musty sala, drain smells in temple toilets or a sour smell in a shop storeroom all signal ongoing moisture and microbial activity. Masking the smell does not reduce germs.

Who is most at risk

Young children, older adults, pregnant women, people with diabetes, kidney or lung disease, anyone with foot wounds, farmers wading daily, and volunteers running central kitchens or cleaning shared toilets. Anyone with high fever, calf pain, severe diarrhoea or a fever that will not break should see a doctor immediately. Spraying reduces germs in the environment; it is not medical treatment.

Mold in Buriram's sala halls, storerooms and community buildings: the right order of work

Black stains and musty smells are what people notice first. What they do not see is the moisture inside materials that lets mold return after wiping. Work in this order:

1. Sort and discard: mats, mattresses, pillows, blankets and cardboard that soaked for long or carry deep mold cannot be cleaned inside.
2. Remove mud and wash: floors, walls, table legs, shelves and kitchen equipment, with detergent, above the waterline.
3. Dry: open doors and windows, use fans, pull items away from walls, and allow one to two days if possible.
4. Spray: once surfaces are clean and reasonably dry, spraying tackles the germs still on them.
5. Monitor: check damp spots for one to two more weeks; if mold returns, find the moisture source first.

For weaving groups, wet silk yarn and cloth should be handled by the weavers' own methods and kept out of the spray zone. Wooden looms can be washed and dried, and the building sprayed once yarn and cloth are removed. Stored milled rice and paddy must always be moved out before spraying.

What Buriram risks if disinfection is skipped

Health: diarrhoea spreading through villages after shelter stays, hand-foot-mouth disease from child centres, coughs and allergies in older people living in damp homes, and leptospirosis risk for farmers.

Income: a noodle shop or store closed for a week loses a week of income; moldy stock must be thrown out; and customers who fall ill may not return.

Time: after the water drops, farmers must tend their fields and prepare for the year-end harvest. Caring for sick relatives or repeated cleaning takes that time away.

Community: festivals, village meetings and children's schooling all depend on shared spaces. If people doubt they are safe, community life recovers slowly.

Family: parents working far from home, who leave children with grandparents, worry especially when they hear the house and school back home have flooded.

Common fixes that are not enough for Buriram's temples, markets and schools

• Washing with well or village tap water only: removes mud but does not kill germs, and unclean wash water can add more.
• Mixing bleach with toilet cleaner: mixing products can release dangerous gas, and pouring on floors misses walls, table legs and touch points.
• Spreading lime everywhere: often used on outdoor ground, but unsuitable for indoor surfaces, kitchens and frequently touched items, and the dust irritates.
• Incense or air freshener: masks odour while germs remain.
• A few volunteers wiping a whole sala: large halls and schools take a long time and coverage is uneven.

These steps have a place, but none is designed to cover large areas and several germ groups at once. Professional spraying after cleaning fills that gap.

WHD disinfection spraying for Buriram: ULV mist and CHEMGENE HLD4H

World Health Disinfection (WHD) provides disinfection spraying for homes, buildings and public places. According to the service information, trained technicians spray and/or use ULV (Ultra Low Volume) fogging. The very fine mist spreads through the space and settles on sala floors, pillars, table legs, shop shelves, counters, stair rails and corners a cloth cannot reach, which suits large spaces such as sala halls, classrooms, markets and storerooms.

Spraying comes after mud removal because mud and grease shield germs. On clean surfaces the mist makes direct contact.

The disinfectant is CHEMGENE HLD4H, a medical-grade product 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-mouth disease virus, with a stated efficacy of 99.99%. The service page lists approvals or endorsements from Thailand's Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019.

How it works

1. Book: call 065-556-6294 or LINE @whd268 with the district (Nang Rong or Prakhon Chai), subdistrict, type of premises, floor area and photos.
2. Prepare: remove mud, wash surfaces, discard ruined items, and move food, rice, silk yarn, cloth and personal items out.
3. Spray: people, monks, children and pets leave the zone; technicians work from the far end towards the door.
4. Wait about 30 minutes: according to the service information, then re-enter when advised.
5. Ventilate: and resume normal use.

Coverage: WHD is based in Bang Khae, Bangkok, and has no branch in Buriram. Jobs in Nang Rong and Prakhon Chai are planned by phone or LINE, with travel date, scope and cost confirmed in advance. Same-day arrival cannot be promised. Temples, schools or shops in the same subdistrict booking the same day makes travel easier to plan.

For closed rooms where a musty smell lingers after spraying, residential ozone disinfection can be added.

Promotion: according to the service information, customers receive a free CHEMGENE spray bottle and WELLGIENIC wet tissues, and a tax invoice is available.

Spraying plans for each kind of place in Nang Rong and Prakhon Chai

• Temples, sala halls and kitchens: collect shelter mats and blankets, wash and sun-dry what can be saved, discard what soaked; wash the sala, toilets and kitchen; discard food and condiments the water reached; then spray before the festival.
• Nang Rong markets and food stalls: discard soaked wooden boards, wash stalls, trays and drains, and spray after closing with all food removed or covered.
• Shophouses, wholesalers and storerooms: lift saleable stock high or move it out, discard wet cardboard and contaminated goods, wash and dry shelves and floors, then spray floors, lower shelves, counters and customer touch points.
• Noodle shops and restaurants: discard all ingredients the water touched, wash pots, mortars, fridges and drains, spray kitchen, dining area and toilet, then rinse food-contact surfaces as advised.
• Schools and child centres: ground-floor classrooms, toilets, canteen and nap rooms first; discard soaked mats and books; spray on a day with no children.
• Government offices and health centres: counters, waiting chairs, rails, handles and public toilets, outside service hours.
• Weaving groups and lodging near tourist sites: remove yarn and cloth, wash and dry looms, then spray the building; for lodging, change wet linen, wash bathrooms and spray rooms and common areas before guests return.

10 reasons Buriram temples, shops and schools should spray after the flood

5. Endorsements on the service page: Department of Medical Sciences, Mahidol University, NHS England and EN 14476.
6. About a 30-minute wait: according to the service information, so shops and markets reopen quickly.
7. Confidence for festivals and classes: temples and schools can tell the community disinfection has been done.
8. Tax invoice available: useful for shops, schools and agencies; see the disinfection service page.
9. Free follow-up items: CHEMGENE spray bottle and WELLGIENIC wet tissues for touch points.
10. Experience across many settings: according to the service information, customers include hospitals, schools, malls, airports, offices, airlines, banks and residential buildings.

Before and after spraying in Buriram temple halls and shops

Results depend on cleaning, drying and ongoing care. If materials stay wet inside, mold can return.

Example case: a grocery wholesaler in Nang Rong town

Chai (a fictional name) runs a grocery wholesale business in a double shophouse in Nang Rong town. Most customers are village grocers from outlying areas who restock weekly. Water about a hand-span deep entered the shop and back storeroom, soaking drinking-water cases, instant-noodle cartons, sugar sacks and floor-level boxes.

After it receded, Chai and his staff removed everything with damaged or wet packaging, threw out the cardboard, lifted good stock onto high shelves, washed floors and shelving with detergent and left both doors open for two days. The storeroom still smelled musty, and one employee started sneezing and itching every time he went in.

He contacted WHD on LINE with photos and the floor area. The team planned the trip from Bangkok in advance. On the day, Chai closed for the afternoon, covered stock on the high shelves and cleared everyone out. The technicians sprayed floors, lower shelves, the counter and the toilet. After the advised wait he ventilated, restocked and opened the next morning, and he now plans to raise pallets off the floor and keep watching damp spots for two weeks.

Note: this is an illustrative example case. Names and details are fictional.

Buriram flood recovery checklist, before and after spraying

Before

• Cut power to flooded areas and have an electrician check.
• Wear boots, rubber gloves and a mask; cover wounds before handling mud.
• Remove mud and wash hard surfaces with detergent.
• Discard mats, mattresses, pillows, cardboard, moldy materials and any food or condiments the water touched.
• Move milled rice, paddy, silk yarn, cloth and farm chemicals out of the area.
• Ventilate and dry; send photos to LINE @whd268.

On the day

• Everyone and all pets leave the zone; dishes, food and personal items are put away.
• Wait about 30 minutes and re-enter when the technicians advise.

After

• Ventilate and watch damp spots for one to two weeks; wipe shared toilets and counters with the free spray.
• If mold or smell returns, find the moisture source, then consult the team.
• Anyone with high fever, calf pain, severe diarrhoea or a persistent fever should see a doctor immediately.

FAQ: post-flood disinfection spraying in Buriram

Does WHD have a branch in Buriram?

No. WHD is in Bang Khae, Bangkok. Work in Nang Rong and Prakhon Chai is planned by phone on 065-556-6294 or LINE @whd268, with the travel date confirmed in advance. Same-day arrival cannot be guaranteed.

Monks still live at the temple. How does spraying work?

By zones, for example the sala first, then the kitchen and toilets. Everyone leaves each zone while it is sprayed and returns when the technicians advise.

Can a shop be sprayed with stock on the shelves?

Food and unsealed goods should be moved out or tightly covered. The team will advise from your photos.

Will mold never come back?

That cannot be guaranteed. If materials stay wet or leaks continue, mold may return, so deal with moisture and ventilation as well.

Spraying or ozone?

Spraying suits surfaces in large shared spaces. Ozone treatment works in closed, empty rooms for airborne odour.

Someone got sick after wading. What now?

See a doctor immediately and mention the water and mud exposure, especially people with diabetes or anyone with high fever and calf pain. Spraying is not medical treatment.
