In Ko Phlap Phla sub-district, Mueang Ratchaburi, in 2026 (B.E. 2569), floodwater reached almost four metres in places and more than a hundred households were badly hit. When the water drains away, the problems are not only mud and ruined belongings. Dermatophytes, the skin fungi behind ringworm, athlete's foot, jock itch and fungal nail infections, thrive on damp skin and spread through shed skin flakes left on carpets, mats, shoes, foot towels and floors. This guide explains what these fungi are, why cases rise after floods, the signs to watch for, how to prevent spread at home, and when ozone disinfection after the Ratchaburi flood makes sense: always after cleaning and drying, and always in an empty room.
According to Amarin TV on 2 October 2026 (B.E. 2569), Moo 2, 3 and 4 of Ko Phlap Phla sub-district in Mueang Ratchaburi were flooded, with water nearly four metres deep at some points. More than 100 households were seriously affected, more than 900 rai of farmland was damaged, and residents were evacuated during the night of 1 October. The cause was discharge from the Mae Klong Dam combined with high sea tides (source: Amarin TV, 2 Oct 2026). Figures change daily, so follow local announcements too.
Nationally, the Department of Disaster Prevention and Mitigation reported, as of 06:00 on 7 October 2026 (B.E. 2569), flooding in 27 provinces plus Bangkok, 123 districts, 984 sub-districts, 1,154,875 households and more than 3.1 million people (source: Government Public Relations Department).
Ko Phlap Phla is low land beside the Mae Klong River, where most families farm rice, vegetables and fruit. Many homes are raised wooden houses or two-storey concrete houses. With water close to four metres, some were submerged almost to the upper floor. Everything downstairs, from carpets and mats to mattresses, shoes and clothes, sat in water for days.
Example case written to illustrate a common situation. It is not an interview with any resident.
Uncle Chai and his two sons live in a two-storey concrete house near the river. On the night of 1 October the village head called for evacuation. The family carried only some belongings upstairs and went to a temporary shelter, where everyone shared bathrooms, walked barefoot or in wet sandals all day, and slept on mats laid side by side.
Back home after the water fell, the ground floor was thick with mud. The big living-room carpet was heavy with water, the vinyl mats and doormats smelled musty, and several pairs of canvas shoes left in the downstairs shoe cabinet were spotted with white mold. Everyone cleaned all day in rubber boots that never saw the sun.
Two weeks later, the younger son had itchy, peeling skin between his toes. The older son had a red ring-shaped rash on his inner thigh. Uncle Chai had a ring on his arm after cuddling the cat, which had spent days padding through mud. At the local health centre, staff said these may be fungal skin infections, gave treatment, and warned that the home mattered too: skin fungi survive in shed skin flakes on floors and carpets, and without dealing with them, infections can return or pass between family members.
The family threw out the big carpet, washed mats and fabrics in hot water, scrubbed and sun-dried shoes, mopped the tiles, opened the house to dry, and then asked about ozone for the bedrooms and living room to deal with musty air, on a day when everyone was out at the farm.
Dermatophytes are a group of fungi that feed on keratin, the protein in the outer layer of skin, hair and nails. That is why they infect only these surface tissues and do not invade deeper in healthy people. The common genera are Trichophyton, Microsporum and Epidermophyton.
The infections are named by body site:
Skin fungi come from three sources: other people, animals and soil. Some live on human skin and are shed with skin flakes onto floors, carpets, mats, foot towels and shoes; others pick them up by walking barefoot or sharing items. Some come from dogs and cats and spread through cuddling or sharing a bed. Others live in soil and can infect skin after long contact with mud.
Infected skin flakes can survive in the environment for months, especially in damp carpets, mats and shoes. That is why infections often return even after a rash clears with treatment, if the source is still in the house.
Feet wet all day. During and after the flood, people wade, work in mud and wear boots for hours. Soaked skin softens and loses its natural barrier, so fungi get in easily. The soggy "water-bitten feet" Thais call nam kat thao often begin as irritation, but left alone they can pick up fungal or bacterial infection.
Close living in shelters. Evacuation on the night of 1 October meant shared bathrooms, mats laid close together and swapped sandals, all of which make it easier to pass on infected skin flakes.
Flooded carpets, mats and shoes. The items that touch feet most absorb water and dry slowly. Reused while damp, they both store fungi and provide the moisture that helps them grow.
Wet, muddy pets. Dogs and cats stuck in water and mud for days may develop rashes and patchy hair loss. Cuddling an infected animal can pass fungi to people.
Mud left indoors. River and farm mud contains many microbes. Handling it barehanded or barefoot raises the risk of fungal infection and infected wounds.
Hot, humid weather. October still brings showers. Houses closed for days stay humid, clothes dry slowly and skin folds stay sweaty.
The same spots also hold bacteria, molds and flood odours, so the fix has to be a system: discard what cannot be saved, wash what can, dry everything, then look after the room's air and surfaces.
This is general information, not a diagnosis. Many rashes look alike. See a doctor or pharmacist, and avoid using steroid creams on your own, which can make fungal rashes spread and harder to identify.
Anyone who waded through floodwater and develops a high fever, calf pain or red eyes must see a doctor promptly and mention the exposure, as this may be leptospirosis, a bacterial disease unrelated to skin fungi.
Where water reached close to the upper storey, mud lines and damp patches often run up stairwells and onto the upper landing. Wet-mop these areas too, and wash any rugs or mats that were carried upstairs in a hurry while still wet. Fabrics moved upstairs on the evacuation night may have stayed damp in bags or piles for days; open them, wash them and dry them fully before use. Upstairs bedrooms can also pick up the musty smell from below, so include them in your drying plan and, once clean, in the ozone plan if needed, so the whole house recovers together rather than one floor at a time.
Medication prescribed by a doctor works on the skin, but infected flakes remain in carpets, shoes and floors. Without dealing with the source, reinfection stays likely.
A big carpet soaked in muddy water for days stays wet underneath even when the top feels dry, and mud is trapped in the fibres. Health agencies advise discarding carpets and porous items that cannot be cleaned and dried quickly.
Shoes washed and left in the shade stay damp inside for days, and boots worn daily never dry. Keep two pairs to alternate and dry them in strong sun.
Musty smells from carpets, mats and shoes signal moisture and microbes. A spray smells nice for a while but leaves the cause in place.
Sweeping dried mud dust stirs up dust and skin flakes. Mop wet with cleaner, then dry the floor.
Even after stripping and washing, rooms closed for a long time hold musty, earthy odours and humidity in the air, curtains and furniture. This is where ozone in an empty, cleaned room can help.
Ozone (O3) is a strongly oxidising gas. According to the company, it breaks down the cell structures of viruses, bacteria and fungi and the molecules that cause odours, then reverts to oxygen (O2) with no chemical residue. The company states its service has been tested and certified by Thailand's Department of Medical Sciences and Intertek (UK) for eliminating viruses, bacteria and fungi at 99.99%, according to the company's certification.
For dermatophytes, we do not claim ozone eliminates this group specifically. Skin fungi belong to the fungi, one of the groups WHD's service targets according to the company, and you can ask the team for test data. The foundations of prevention are discarding carpets and items that cannot be saved, washing what you keep, drying everything and following medical treatment. Ozone is a supporting step for air, musty odours and surfaces in rooms that are already clean.
Ozone does not penetrate deep into a thick, wet carpet, into every damp corner of a shoe, or dry a waterlogged wall, so cleaning and drying always come first.
Room-treatment ozone irritates the airways and can cause a stinging nose, coughing and chest tightness. Follow these rules every time:
They are fungi that feed on keratin in skin, hair and nails. They spread by contact with infected people, pets, soil and items carrying skin flakes such as carpets, mats, shoes and foot towels.
Soggy flood feet usually start as irritation from long soaking; athlete's foot is a fungal infection. Softened skin can pick up fungi or bacteria, so see a doctor if it itches badly, cracks or oozes.
Usually a round or oval patch with a raised red edge and paler centre that slowly spreads. Many rashes look similar, so get it checked.
Large or thick carpets soaked in muddy water that cannot be cleaned and dried quickly should go. Small washable mats can be hot-washed and sun-dried.
Wash inside and out and dry in strong sun. Heavily molded canvas or leather shoes that still smell should be discarded.
The company states its service targets viruses, bacteria and fungi at 99.99% according to its certification. We make no claim for dermatophytes specifically; ask the team for test data, and strip, wash and dry first.
Yes, if you stay in the room. It must be empty and closed, then rested and ventilated before re-entry. Done correctly, ozone reverts to oxygen.
