When rural road Chor Chor 4023 (ฉช.4023), running through Ratchasan, Bang Khla and Khlong Khuean districts in Chachoengsao, went under water in early October 2026, daily life for everyone who depends on it changed overnight. Getting to work, school, the market or hospital meant riding in trucks arranged by the authorities, and many people had to wade a short distance to climb aboard. Homes, shops and community buildings in the low-lying land around the route are also prone to standing floodwater. This guide summarises the news facts, explains at least eight flood-borne germs linked to flooded roads and farmland around Chor Chor 4023, and shows how cleaning followed by a professional disinfection spraying service helps roadside homes and businesses reopen more safely.
According to Manager Online, on 6 October 2026 the Department of Rural Roads reported that six rural road routes in Chachoengsao were flooded. Route Chor Chor 4023, which passes through Ratchasan, Bang Khla and Khlong Khuean districts, had water 80 centimetres deep, and 50 centimetres in some sections. Other routes named in the report were Chor Chor 4049 at 60 centimetres and Chor Chor 3003 at 50 centimetres. Trucks were mobilised to carry people who needed to travel along the flooded routes.
Nationally, according to Department of Disaster Prevention and Mitigation (DDPM) data published by the Government Public Relations Department, as of 06:00 on 7 October 2026 flooding covered 27 provinces plus Bangkok, 123 districts and 984 subdistricts, affecting 1,154,875 households, or more than 3.1 million people. Figures change daily; check route conditions and the latest announcements before travelling.

The report does not give a number of affected homes along the road, so this article does not include one and uses an example case to describe common situations.
Note: this is a typical scenario based on what often happens when rural roads flood. It is not about any real person or business on Chor Chor 4023.
Noi has run a small curry-and-rice shop in front of her house on a rural road in Bang Khla District for years. Her regulars are workers on motorbikes, teachers on their way to school and villagers heading into town. When heavy rain pushed water from the surrounding fields over the road, the shop had to close. The forecourt went under, water seeped into the kitchen at road level, and the floor-standing chest freezer went off when the power had to be cut.
While the road was still deep in water, Noi and her son waded out to catch the truck the authorities had arranged so they could buy essentials. Her son cut his foot on hidden debris without noticing, and by the next day the wound was red. When the water receded, a thin layer of mud covered the kitchen. Wooden chopping boards and tables bore water stains, food trays sat in a puddle under the counter, the smell of spoiled food mixed with mud, and the lower concrete wall began showing green-black mould spots.
Noi wanted to reopen quickly because the shop is the family's main income, but she worried customers might get sick from food cooked in a kitchen that had just flooded. Her question is shared by many homes and shops along rural roads: what has to be done before it is safe to cook and use the space again?
Water covering rural roads around Ratchasan, Bang Khla and Khlong Khuean is not clean rainwater. It has flowed across rice fields, orchards, animal pens, household septic tanks and roadside drains, picking up mud, animal droppings, fertiliser, farm chemicals and rubbish. With water 50 to 80 centimetres deep on the road, as reported, anyone wading or waiting for transport is in direct contact with it up to the legs.
Second, the trucks carrying residents are shared spaces used by older people, schoolchildren and workers in wet clothes and shoes, so germs pass easily through hands and shared surfaces. Third, homes, shops, schools, temples and community buildings along the road are often built at roughly road level, so when the road floods, water tends to enter their yards and ground floors too.
Finally, the farmland around the route is a source of mud that may contain soil bacteria. When the water drops, that mud settles on roads, yards and floors. Correct cleaning matters both for families at home and for customers of roadside shops.
The following is general public-health information about germs found after floods on roads and farmland. It is not a test result from this area and not treatment advice. If you feel unwell after wading or after the water recedes, see a doctor.
How floodwater spreads it: urine from rats and field animals mixes into water running across the road, so people who wade to the trucks or stand in water for long periods can be exposed through cuts or skin softened by soaking. Where it hides after the water recedes: roadside puddles, drains, yards and wet mud in sheds or storerooms. Symptoms and who is at risk: sudden high fever, headache, calf pain and red eyes; farmers and frequent waders face higher risk. Prevention: wear boots, wash legs and feet with soap after wading, and tell a doctor about wading if a fever appears.
How floodwater spreads it: a soil and surface-water bacterium found in many parts of Thailand, especially in paddy soil and wet ground; floods carry field mud onto roads and into homes. Where it hides: mud in yards, in front of shops and on ground-floor rooms. Symptoms and who is at risk: persistent fever, cough, abscesses or wounds that will not heal; people with diabetes or kidney disease and those working in mud are at risk. Prevention: wear boots and gloves when shovelling mud, cover wounds fully, and mention mud exposure to a doctor if fever develops.
How floodwater spreads it: septic tanks of roadside homes, animal droppings and wastewater mix into water covering the road and entering buildings. Where it hides: restaurant kitchens, chopping boards, dishes, bathrooms and flooded freezers. Symptoms and who is at risk: diarrhoea and cramps, sometimes bloody diarrhoea with certain types; children and older people can become dehydrated. Prevention: discard food and ingredients that touched floodwater, clean then disinfect food-preparation surfaces, and wash hands before cooking.
How floodwater spreads it: through hands, food and water contaminated with faeces, common when tap water stops and toilets are unusable. Where it hides: taps, water scoops, stored-water buckets and kitchen surfaces. Symptoms and who is at risk: diarrhoea with mucus or blood, fever and straining; young children are at higher risk. Prevention: wash dishes in clean water, drink bottled or boiled water, and wash hands with soap.
How floodwater spreads it: through contaminated food and water, especially items not heated, such as ice, raw vegetables and desserts. Where it hides: ice buckets, water containers and food prepared with unclean hands. Symptoms and who is at risk: fatigue, nausea, and yellow skin or eyes. Prevention: discard ice that may be contaminated, clean ice buckets before reuse, cook food thoroughly, and ask a doctor about vaccination if you are in a risk group.
How floods spread it: it passes through saliva, nasal mucus, faeces and shared toys. During floods children often gather in shelters or relatives' homes, and when schools reopen it can spread in classrooms. Where it hides: toys, school desks, stair rails and seats in shared transport. Symptoms and who is at risk: fever, mouth ulcers and a rash or blisters on hands and feet; young children are most at risk. Prevention: wash children's hands often, clean toys and shared surfaces, and keep sick children home as a doctor advises.
How floodwater spreads it: cuts from wood, glass or sharp debris hidden under water on the road let bacteria into the skin. Where it hides: wet shoes and socks, towels and unclean bandages. Symptoms and who is at risk: red, swollen, warm, painful wounds or pus; wounds heal slowly in people with diabetes. Prevention: wash wounds with clean water and soap, keep them covered and dry, avoid wading with an open wound, and ask a doctor about tetanus vaccination for cuts from sharp or dirty objects.
How floodwater spreads it: a moisture-loving bacterium that thrives in still water and on surfaces that stay wet. Where it hides: drains, dish sponges, water buckets and boots that were never dried. Symptoms and who is at risk: skin inflammation, wound infection, and ear infection when water gets into the ear; people with weak immunity are more vulnerable. Prevention: dry boots and equipment thoroughly, replace sponges that sat in floodwater, and flush out drains.
How floods spread them: feet soaked in water or kept in wet shoes all day soften, letting fungi grow. Where they hide: shoes, socks, doormats and bathroom floors. Symptoms and who is at risk: itching between the toes, peeling, soggy and red skin; people who wade to work every day are most at risk. Prevention: wash and dry feet carefully, especially between the toes, change socks often, and do not share shoes.
How floods spread them: walls, ceilings, wooden furniture and paper that stay wet for more than 24 to 48 hours begin to grow mould. Where they hide: lower concrete walls, wooden shop cabinets, cardboard boxes in storerooms and behind fridges. Symptoms and who is at risk: coughing, sneezing, a blocked nose and asthma flare-ups; people with weak immunity risk fungal lung infection. Prevention: discard porous items that stayed wet, ventilate, dry thoroughly and wear a mask when cleaning mould.
How this links to disinfection spraying: WHO and CDC advise cleaning flood-contaminated surfaces first and then disinfecting. According to WHD's service information, CHEMGENE HLD4H is stated to cover viruses, bacteria and fungi, with named organisms including hand-foot-and-mouth virus, norovirus, Salmonella, RSV and influenza H1N1. The other germs in this list, such as Leptospira, Burkholderia, E. coli, Shigella, hepatitis A, Staphylococcus, Pseudomonas and dermatophytes, belong to the bacteria, virus or fungi groups the product says it covers, but this article claims no specific test result for them. Ask WHD directly for test data on any particular organism.
Health: people who wade to work or school every day face leptospirosis, foot fungus and wound infections, while customers of roadside eateries face stomach illness if kitchens are not properly cleaned.
Income: shops, eateries and small roadside businesses close while the road is flooded. Once the water drops, owners want to reopen fast, but a single case of customers falling ill can damage a shop's reputation for a long time.
Time and travel: relying on transport trucks makes every trip longer, leaving little time to clean homes and shops.
Community: schools, temples, community halls and other shared buildings must be clean and safe before reopening so they do not become places where germs spread after the flood.
After mud removal and washing, disinfection spraying by trained technicians is a useful extra step that reduces germs on surfaces systematically before a shop or building reopens or a family moves back in.
According to World Health Disinfection (WHD) service information, trained technicians spray and/or apply a fine ULV (Ultra Low Volume) mist using CHEMGENE HLD4H, a medical-grade disinfectant from the United Kingdom containing Benzalkonium Chloride and Didecyldimethylammonium Chloride. The service page states it covers viruses, bacteria and fungi, including COVID-19, RSV, H1N1, H5N1 and hand-foot-and-mouth virus, claims 99.99% efficacy, and lists approvals or references from the Thai Department of Medical Sciences, Mahidol University, NHS England and EN 14476:2013+A2:2019. Customers listed on the page include hospitals, schools, malls, offices, banks and residential buildings.
WHD is based in Bang Khae, Bangkok 10160. Jobs in Chachoengsao, including Ratchasan, Bang Khla and Khlong Khuean, are arranged via 065-556-6294 or LINE @whd268. There is no branch in the province and flood-season demand is high, so contact the team early. Agencies wishing to treat shuttle vehicle cabins or other non-building spaces can ask the team directly whether this is possible, and if musty smells remain after spraying, ask about the complementary residential ozone disinfection service.
While the road is still flooded
When the water recedes
Before and after spraying
Q: Should an eatery be disinfected before reopening?
A: Yes, after mud removal and washing, to help reduce germs on kitchen and customer-area surfaces, together with discarding food that touched floodwater and washing dishes properly.
Q: How long before we can use the space?
A: According to the service information, about 30 minutes, but follow the technicians' time on the day and ventilate first.
Q: I waded on the road and now have a fever. What should I do?
A: See a doctor promptly and mention the wading, as it may be leptospirosis or another infection. Disinfecting a home is not a substitute for medical care.
Q: Can spraying replace washing?
A: No. Mud removal and washing always come first, because mud and grime block the disinfectant from reaching germs.
Q: Does WHD serve Ratchasan, Bang Khla and Khlong Khuean?
A: WHD is in Bang Khae, Bangkok, and arranges Chachoengsao jobs via 065-556-6294 or LINE @whd268. Dates depend on the queue.
Q: Can schools or agencies get a tax invoice?
A: According to the service information, yes. Pricing depends on area size and condition; send photos for an assessment first.
Q: Is the product residue-free?
A: This article makes no residue-free claim. For food-preparation areas, follow the team's guidance and ask for the product's safety information.
