Lopburi Flooding in Early October 2026: What the DDPM Report Says

All place facts here come from a single source: the DDPM report published by Daily News on 1 October 2026. Figures are as of that date and change daily.

• Flooding in 5 Lopburi districts: Mueang Lopburi, Tha Luang, Phatthana Nikhom, Khok Samrong and Ban Mi.
• 23 subdistricts, 84 villages and 1,657 households in total across those five districts.
• Water levels were rising at the time of the report.

The report does not give water depth, the cause of flooding in each district, or village names, so we do not state any depth or detail the source does not contain. We focus on Tha Luang, Phatthana Nikhom and Khok Samrong and use a typical farming household as the frame for the ranking. The family story below is an illustrative example, not a real person.

Flooded Areas in Lopburi: Tha Luang, Phatthana Nikhom and Khok Samrong

Per the 1 October 2026 DDPM report, five Lopburi districts were flooded. This article focuses on three of them:

• Tha Luang District, one of the five districts in the flood report.
• Phatthana Nikhom District, one of the five districts in the flood report.
• Khok Samrong District, one of the five districts in the flood report.

Readers in Mueang Lopburi and Ban Mi, the other two districts listed, can apply the same principles. For subdistrict and village details, check with the district office, the subdistrict administrative organisation or Lopburi province directly. What we can confirm is only that these three districts were in the flood report and that water was rising on the reporting date.

Example Case: A Farmhouse Where Water Reached the Cattle Pen and the Rice Store at Once

A typical scenario (illustrative, not a real person)

Prayoon farms rice and keeps five cows behind the house. His wife raises laying hens and sells eggs in the village. A small wooden rice store holds the paddy left from last season, meant to feed the family all year. When the water began to rise they led the cows to a higher road and moved the hens onto a raised bamboo platform, but the rice store could not be moved. Water crept under its floor and soaked the bottom sacks.

When the water dropped, the yard was a mix of mud and cow dung, the pen smelled strongly, and the lower rice sacks showed green mould and a musty smell. Their teenage son helped carry things in flip-flops and cut his foot on a piece of corrugated iron. Their youngest daughter came home from the subdistrict school saying several friends had fevers.

The family had questions. Can mouldy rice still be eaten? How should the pen be cleaned? Does the son need a tetanus shot? What must be done before the children sleep inside again? The wound question has a clear answer: see a doctor. The rest is why we wrote this ranking.

How WHD Built This Post-Flood Germ Ranking for Lopburi

This is an editorial ranking by WHD, not an official one, and it is not based on Lopburi case data, which we do not have. Our criteria:

1. Flood relevance in WHO, CDC and Thai Department of Disease Control guidance.
2. Fit with farming households: livestock, grain stores, farm tools and daily contact with wet soil.
3. Severity based on general medical knowledge.
4. Risk groups: farmers, people with diabetes, older adults, schoolchildren and pregnant women.
5. Persistence, described qualitatively only.
6. Ease of spread from animals to people, person to person and through food.

A lower rank does not mean a germ is safe. Protect against all ten together, and see a doctor if you feel unwell.

Post-Flood Germ Ranking Lopburi 2026: The Top 10 for Farmhouses, Pens and Grain Stores

1. Leptospira (Leptospirosis) from Rats in Grain Stores and Animal Urine in Pens

Why first: On a farm, every leptospirosis risk factor is present at once. Rats live in rice stores and sheds, cattle, buffalo and pigs can carry the bacteria, and family members must step into water and mud to tend animals and crops. Thailand's Department of Disease Control warns about it every rainy season, especially for farmers.

Where it hides: mud in pens, under the rice store, the yard, drainage ditches and sack piles where rats nest.

Symptoms and risk: sudden high fever, headache, strong calf pain and red eyes; severe cases affect the kidneys or liver. Farmers with foot or leg wounds face the highest risk. Fever after wading or working in mud means seeing a doctor and mentioning that exposure.

Prevention and disinfection: wear rubber boots and gloves when cleaning pens or moving sacks, cover wounds, remove rat food sources and wash after work. Clear mud and dung first, then spray living areas, stores and shared spaces. Leptospira belongs to the bacteria group CHEMGENE HLD4H says it covers, but no specific test result is shown online; ask WHD for data.

2. Mould in Rice Stores and Homes: Aspergillus and Penicillium

Why second: Farm families store crops in or near the house. Wet rice, maize or beans grow mould quickly, and some Aspergillus species can produce aflatoxin in damp grain, a well-known food safety concern. Walls, mattresses and wooden cupboards grow mould too.

Symptoms and risk: breathing mould dust causes coughing, congestion and eye irritation, and can trigger asthma and allergies. People with weakened immunity should not handle mouldy grain.

Prevention and disinfection: mouldy or musty grain should not be eaten or fed to animals; separate and dispose of it. Wear a mask and gloves, ventilate, and dry the store fully before refilling. Spraying treats surfaces of the store and home after cleaning. The service information covers fungi and mould in general, without separate tests for these genera, and spraying never makes mouldy rice edible.

3. Salmonella and Campylobacter from Coops and Pens

Why third: Both are common in the gut of poultry and livestock. Floodwater spreads manure across the yard, and people and animals live closer than usual, so germs reach kitchens and hands more easily.

Where it hides: the yard, paths from pen to house, shoes, temporary cage platforms, eggs and feeding trays.

Symptoms and risk: fever, diarrhoea, cramps, nausea and vomiting; children and older adults dehydrate faster.

Prevention and disinfection: keep separate shoes for the pen, wash hands after handling animals and eggs, and cook meat and eggs thoroughly. Salmonella is listed in the CHEMGENE HLD4H product information; Campylobacter is not, so it sits in the general bacteria group. After manure is washed away, spraying human areas reduces what remains. All animals stay out until the stated re-entry time.

4. E. coli (Escherichia coli) from Latrines and Livestock Manure

Why fourth: In rural areas E. coli comes both from household latrines and from livestock manure, and floods mix the two. Some strains live in cattle and can cause serious illness in people. It ranks fourth because the main route is water and food, which families can protect fairly directly.

Symptoms and risk: diarrhoea and cramps, sometimes bloody stools. Bloody diarrhoea or reduced urination needs a doctor.

Prevention and disinfection: drink boiled or bottled water, avoid flooded shallow wells until checked, discard flooded garden vegetables and wash hands before eating. E. coli falls in the general bacteria group, without a specific test shown online.

5. Burkholderia pseudomallei (Melioidosis) from Soil and Muddy Water

Why fifth: This bacterium lives in soil and water in many parts of Thailand and is well known to be linked with farm work in wet soil, especially in the rainy season. Infection can occur through skin wounds, inhalation or ingestion, and people with diabetes are a key risk group.

Symptoms and risk: fever, cough, abscesses or non-healing wounds and many other presentations. Diabetes, kidney disease and heavy drinking raise risk. Persistent fever after working in mud means seeing a doctor and mentioning your occupation.

Prevention and disinfection: wear boots and gloves, cover wounds and wash promptly. Spraying cannot treat soil in fields, but it reduces germs on indoor surfaces where mud was tracked in. This organism is not on WHD's list, so it sits in the general bacteria group only.

6. Tetanus Risk (Clostridium tetani) from Farm Tools and Debris

Why sixth: Post-flood clean-up on a farm means corrugated iron, nails, barbed wire and tools. Tetanus spores live in soil and manure, so deep dirty wounds carry risk. This is about wound care and vaccination, not home disinfection.

Prevention: wear closed shoes and gloves, rinse wounds with clean water and see a doctor about vaccination. Bacterial spores resist many disinfectants, so we do not claim spraying prevents tetanus.

7. Hand, Foot and Mouth Disease Viruses in Subdistrict Schools and Childcare Centres

Why seventh: When children return to classrooms that have just been flooded, shared toys and desks spread germs easily. Hand, foot and mouth disease is common in the rainy season and spreads through saliva, mucus and stool.

Symptoms and risk: fever, mouth sores, and spots on the hands, feet and buttocks. Drowsiness, frequent vomiting or trembling needs urgent care.

Prevention and disinfection: frequent handwashing, sick children stay home as advised by a doctor, and daily toy cleaning. The service information lists hand-foot-mouth virus among covered organisms, so schools can book spraying after classrooms are cleaned, with children and staff out of the area.

8. Norovirus in Temple Kitchens and Community Halls

Why eighth: During floods, rural communities often run shared kitchens at temples or halls. Large batches cooked with uncertain water, plus many people sharing toilets, suit norovirus well.

Prevention and disinfection: people with vomiting or diarrhoea stay out of the kitchen, everyone washes with soap, and toilets are cleaned often. Norovirus is listed in the product information, making spraying a good fit for shared kitchens, toilets and halls after cleaning.

9. Influenza and COVID-19 at Gathering Points

Why ninth: Village meetings, relief handouts and temporary shelter bring many people together. These viruses do not come from floodwater, but floods help them spread.

Prevention and disinfection: masks when sick, handwashing and ventilation. COVID-19, H1N1 and H5N1 are listed by the service, so spraying halls after use reduces them on surfaces, without replacing personal hygiene.

10. Skin Fungi (Dermatophytes) and Staphylococcus aureus

Why tenth: Farmers in water and mud all day often get immersion foot, followed by fungal or bacterial infection. Usually mild, but troublesome for work and riskier for people with diabetes.

Prevention and disinfection: dry feet, change socks, dry shoes, and see a doctor for red, swollen or pus-filled wounds. Wash and spray bathroom floors and shoe-off areas; these organisms fall in the general fungi and bacteria groups.

What Flooding Costs Lopburi Farming Families

Health: farmers return to the mud as soon as the water drops, so they meet soil and animal germs more than most people, while children go back to school and elders stay in damp homes. Income: mouldy stored rice must be thrown out, stressed animals may fall ill and tools are damaged, all while income drops. Time: the house, pens, store and fields all need attention at once. Community: temples, schools, halls and village shops are shared by everyone, so if they stay dirty, germs travel from one home to the next.

Warning Signs That Mean See a Doctor Now

Disinfection protects surfaces, not people who are already unwell. In a farming household, symptoms are easy to dismiss as tiredness from clean-up work, so agree as a family on the signs that mean someone goes to the clinic or hospital without waiting:

• Fever after wading or working in mud, especially with strong calf pain or red eyes.
• Diarrhoea with blood or mucus, repeated vomiting, or very little urine.
• A wound that becomes red, hot, swollen or full of pus, or any deep, dirty puncture wound.
• Persistent fever or a non-healing sore in someone with diabetes who has worked in wet soil.
• A child with mouth sores who becomes drowsy, vomits often or trembles.
• Shortness of breath in an older person or someone with asthma after cleaning mouldy rooms or grain.

Always tell the doctor that you have been in floodwater, mud or around livestock. That single detail helps them consider the right causes early.

Why Ordinary Cleaners Alone May Not Be Enough on a Farm

• Many different areas and materials: wood, concrete and corrugated iron across the house, kitchen, bathroom, store and shed.
• Organic soil from manure weakens disinfectants unless it is washed off first.
• Home-mixed bleach risks the wrong strength or dangerous gases if mixed with other products.
• Short contact time when surfaces are wiped and rinsed immediately.
• Limited labour, since family members must also care for animals and fields.

CDC advises cleaning before disinfecting. Spraying by trained technicians is the follow-up step that reaches surfaces more evenly.
