The 2026 (B.E. 2569) Huai Khwang Flood: What Was Reported

According to Nation TV, on the morning of 25 September 2026 Vibhavadi Rangsit Road through Huai Khwang had 10 to 15 centimetres of standing water along about 600 metres, and Phetchaburi Road had 5 to 10 centimetres. Thai PBS reported that on 26 September 2026 the BMA measured 14.7 centimetres on New Phetchaburi Road, where water had been collecting since 15:10 on 25 September.

Naewna reported that at 18:30 on 25 September 2026, the BMA listed Pracha Uthit Road opposite the Huai Khwang District Office as a flooding point, and it was reported that DDPM declared flood-assistance zones in Bang Kapi, Samsen Nok and Huai Khwang subdistricts.

Across Bangkok, Thai PBS reported more than 300 millimetres of rain in about 48 hours over 25 to 26 September 2026, and all 50 districts were declared disaster areas on 26 September. DDPM reported on 6 October 2026 that about 329,000 Bangkok households were affected. Nationally, DDPM reported, as of 06:00 on 7 October 2026, that 27 provinces plus Bangkok were affected, covering 123 districts, 984 subdistricts and 1,154,875 households, with more than 3.1 million people affected. These figures reflect report dates and change daily; follow the Huai Khwang District Office and the BMA.

Huai Khwang is an inner-city district of condominiums, apartments, dormitories, shophouses, soi communities, offices and nightlife. Many residents ride the MRT and walk the rest of the way, crossing flooded pavements and roads.

A Typical Scenario: A Small Rented Room Where Everyone Got Pink Eye

Example case written to illustrate a common post-flood situation. It is not an interview with any Huai Khwang resident.

Mint rents an apartment room off Pracha Uthit with her university-student sister. On the night of the heavy rain, both waded from the mouth of the soi to their building. Passing cars splashed dirty water into their faces, and her sister wiped her eyes with the back of her hand on the way. At home they shared one towel because the other was still damp in the bathroom.

A few days later her sister woke with a red right eye, constant watering, a gritty feeling like sand, swollen lids and a slightly sore throat. Within days the left eye turned red too, and soon Mint's eyes were itching and irritated as well. They had been washing their hands, but they still slept in the same bed on the same pillows.

The doctor diagnosed viral conjunctivitis, noting that adenovirus is a common cause, and advised: no self-bought eye drops, no rubbing, separate towels and pillowcases, wash fabrics daily, and stay home from class or work as advised to avoid spreading it.

Once their eyes cleared, the room still smelled musty from days of indoor drying, and the curtains and doormat smelled of sewage from wet shoes. The right order is to wash towels, pillowcases, sheets and curtains in water as hot as the fabric allows, sun-dry them fully, throw out the smelly doormat, wipe handles, switches and taps, dry the room, and only then consider ozone on a day when the room is empty, to help reduce airborne germs and lingering odour.

What Is Adenovirus, and How Is It Linked to Pink Eye?

Adenoviruses are a group of viruses with many types that cause a range of illnesses: conjunctivitis (pink eye), colds, sore throat, fever, bronchitis and, for some types, diarrhoea in children. Adenoviral pink eye is highly contagious and can spread through homes, dormitories, schools and workplaces.

A key feature of adenovirus is its hardiness. It survives on surfaces and objects for a long time and resists many common cleaning products better than some other viruses. That is why prevention focuses on handwashing, not sharing items, and regularly laundering anything that touches the face and eyes.

Not every case of pink eye is adenovirus. Bacteria, allergies or irritation from dirty floodwater and chemicals can also cause it, and a doctor is needed to tell them apart. Thailand's Department of Disease Control routinely lists conjunctivitis among common flood-season illnesses, alongside skin infections, diarrhoea and leptospirosis.

How does pink eye spread?

• Hand to eye, the most common route: touching something contaminated and then rubbing or wiping the eyes.
• Towels, face cloths and pillowcases carrying tears and discharge, passed to the next user's eyes.
• Shared personal items such as eye drops, eye make-up, glasses and contact lenses.
• High-touch surfaces such as door handles, switches, remotes, taps and phones.
• Droplets from coughs or sneezes when the patient also has respiratory symptoms.
• Unclean water, such as floodwater or poorly maintained pools, splashing into the eyes.

Why Huai Khwang Residents Need Extra Care with Pink Eye After the Flood

• Dirty water splashing into eyes while wading along New Phetchaburi, Pracha Uthit or Vibhavadi, especially when cars pass.
• No way to wash hands on the way home, so people wipe their faces with dirty hands.
• Towels that will not dry during days of rain, leading people to share.
• Small shared rooms in city rentals and dormitories, where separating bedding is hard.
• Fatigue and stress from difficult commutes and short sleep.
• Irritation from contaminated water that makes people rub their eyes more often.

Adenoviral Pink Eye Symptoms and Who Is Most at Risk

• Redness, often starting in one eye and spreading to the other within days
• Heavy watering with clear or slightly sticky discharge; lids may be stuck in the morning
• Gritty, sandy or itchy feeling
• Swollen eyelids and sensitivity to light
• Sometimes fever, sore throat or a swollen gland in front of the ear

Most viral pink eye improves on its own within about one to two weeks, sometimes longer. While the eye is red and watering, it spreads easily, so keep items separate and stay home as the doctor advises.

Groups needing extra care

• Young and school-age children, who rub their eyes and share items
• Newborns: any red eye or heavy discharge needs a doctor right away
• Contact lens wearers
• Older adults and people with weakened immunity
• People living together in rentals, dormitories or shelters

When to see a doctor quickly

See a doctor promptly for severe eye pain, blurred vision, strong light sensitivity, thick pus, redness in a newborn, redness while wearing contact lenses, or no improvement after several days. Never self-medicate with steroid eye drops, which can harm the eye. If you waded through floodwater and have high fever with severe calf pain or deeply red eyes with fever, tell the doctor, because leptospirosis can also cause red eyes. This article is general information, not treatment advice.

Towels, Pillows and Bedroom Hotspots After the 2026 Huai Khwang Flood

• Towels and face cloths: one per person, washed after every use by the patient and dried completely.
• Pillowcases and sheets: tears and discharge soak into them nightly, so change them often while symptoms last.
• Pillows and mattresses that cannot be washed: use protective covers and air them in the sun; consider discarding them if they sat in floodwater.
• Blankets pulled over the face.
• Door handles, switches, taps and remotes touched after wiping the eyes.
• Phones and glasses held close to the face.
• Bathroom towel rails with damp towels hanging side by side.
• Doormats and shoes that went through floodwater and smell of sewage.
• Curtains and damp corners in rooms used for indoor drying, which turn musty and may grow small mould spots.

The Impact on Huai Khwang Residents

Pink eye makes reading and screen work hard, and some people cannot face bright light for days. Patients often stay off work or school as advised, hitting service workers in Huai Khwang's hotels, restaurants and shops directly. In dormitories and small rentals with shared bathrooms, one case puts roommates and neighbours at risk, and landlords and hotels find that musty rooms after a flood or after sick guests make new occupants doubt their cleanliness.

Why Ordinary Laundry, Wiping or Air Freshener Are Not Enough

• Washed but not dried. Towels and pillowcases dried indoors in the rain stay damp, smell musty and get mixed up on a shared rail.
• Separate towels but shared pillows. Pillows are where a patient's tears and discharge collect most.
• Wiping only the obvious spots. Handles and taps matter, but hands also touch bed frames, chargers and towel rails.
• Fragrance only masks. Mustiness from indoor drying and sewage-soaked mats remains, and strong spray can sting irritated eyes.
• Chemicals on dirty surfaces. Adenovirus is hardy and disinfectants work poorly on grime, so wash with water and detergent first and use products as labelled.
• Closing a damp room. Mould starts in corners and behind curtains. The CDC advises cleaning and drying within 24 to 48 hours after flooding.

Bedroom Ozone After the 2026 Huai Khwang Flood with WHD: How It Helps

World Health Disinfection's residential ozone disinfection service releases ozone gas (O3) into a closed, empty room. Ozone is a strong oxidiser that reacts with micro-organism structures and odour molecules, then reverts to oxygen (O2), leaving no chemical film. As a gas it reaches the air, corners, under beds and behind curtains.

According to the company's certification, based on testing by Thailand's Department of Medical Sciences and Intertek (UK), the service eliminates virus, bacteria and mould groups at 99.99%. The service page does not list an adenovirus-specific test, so we describe adenovirus as belonging to the virus group the service targets. Detailed test data can be requested from WHD via the certificates page, by phone or on LINE.

For pink eye, the main protections are handwashing, not rubbing eyes, never sharing towels, pillows or eye drops, and laundering anything that touches the face and drying it fully. Ozone does not replace laundry, does not treat pink eye and does not protect anyone from a person who still has symptoms. Its role is a supporting step after recovery, laundry and room cleaning, to help reduce germs in the air and on hard-to-reach surfaces and to cut mustiness from indoor drying and sewage smells from shoes.

WHD's post-flood bedroom ozone process

1. Survey and assessment. The team asks about room size, property type, odour spots and when the patient recovered, by phone, LINE or on site.
2. Wash, clean and dry first. Launder towels, pillowcases, sheets, blankets and curtains and dry them fully; discard smelly doormats and flood-soaked absorbent items such as foam mattresses, rugs or swollen mouldy gypsum; wipe high-touch surfaces; dry the room.
3. Empty and seal the room. All people, pets and plants leave; doors and windows close; air conditioning off as advised.
4. Ozone cycle. Typically about 30 minutes per zone, depending on size and condition.
5. Rest and ventilate. The ozone breaks down, then doors and windows open for the time the technician sets.
6. Re-entry only when the technician confirms it is safe, followed by regular ventilation.

Is ozone dangerous? Safety rules

• High-concentration ozone irritates the eyes, nose, throat and lungs. No people, pets or plants in the room during treatment.
• Anyone whose eyes are still red or irritated, children, older adults and people with asthma should wait until ventilation is complete.
• Rooms must be clean and dry first. Ozone does not replace laundry, scrubbing, removing soaked materials or fixing leaks.
• Ozone does not penetrate deep into pillows, mattresses or waterlogged walls. Fabrics still need washing, and soaked, mouldy materials should go.
• Anyone with red eyes, eye pain or blurred vision must see a doctor. Ozone treats the environment, not disease.

10 Reasons Huai Khwang Homes and Rentals Should Consider Ozone After the 2026 Flood

1. Treats the air and corners a cloth cannot reach.
2. Helps cut mustiness from indoor drying and sewage smells from wet shoes, the top reason people search for ozone odour removal.
3. A final step for rooms where someone had pink eye, after laundry and cleaning.
4. Targets virus, bacteria and mould groups, per the company's certification citing 99.99%.
5. No chemical residue on pillows, mattresses or items near the face.
6. Helps reduce odour from small mould spots in corners after they are wiped away.
7. Short treatment time: about 30 minutes per zone plus rest and ventilation.
8. Suits condos, apartments, dormitories and hotels in Huai Khwang preparing rooms for new occupants.
9. Follows laundry and cleaning seamlessly, without moving out for days.
10. Consult first on 065-556-6294 or LINE @whd268, or read the ozone service page.

Example Case: An Apartment Near the MRT Where Several Tenants Got Pink Eye

Example case written to illustrate a common situation. It is not a review by any customer.

Pom manages a five-storey apartment block off Pracha Uthit Road, mostly let to office workers and students. While the soi was flooded, many tenants waded home from the MRT. Soon three rooms reported pink eye, and the housekeeper who cleaned rooms began to feel eye irritation too.

Pom posted notices asking affected tenants to see a doctor and avoid the shared laundry room while symptomatic where possible, put hand gel by the lift, and had the housekeeper wear gloves and wipe lift buttons, rails and shared handles several times a day. The sewage-soaked mat by the lift was thrown out and replaced.

When tenants recovered and vacant rooms needed preparing, those rooms still smelled musty from indoor drying. Pom had the curtains washed and rooms cleaned until dry, then consulted an ozone service. The team treated vacant rooms one at a time, sealed each one, informed neighbours and ventilated before handover. Ozone came after patient care, laundry and cleaning, never in place of them.

FAQ: Pink Eye After Floods, Adenovirus and Ozone in Huai Khwang

What causes pink eye after a flood?

Viruses such as adenovirus, bacteria, allergies or irritation from dirty water. A doctor can best tell which.

What does viral pink eye look like?

Red, watery eyes with clear discharge, a gritty feeling and swollen lids, often starting in one eye. Some people also have fever or sore throat.

How does pink eye spread? Can we share a towel?

Through hands that touch the virus and then the eyes, and through towels, face cloths, pillowcases and items near the eyes. Never share towels or pillows while someone has pink eye.

How long does pink eye last? Should I stay off work?

Viral pink eye usually improves within one to two weeks, sometimes longer. Follow your doctor's advice on staying off school or work.

How should I wash towels and pillowcases when someone has pink eye?

Wash them separately with detergent, in water as hot as the label allows, sun-dry fully and wash your hands after handling them.

Does ozone eliminate adenovirus?

According to the company's certification, the service eliminates virus, bacteria and mould groups at 99.99%, but no adenovirus-specific test is listed on the service page. Ask WHD for the data. Ozone does not replace laundry or handwashing.

Is ozone harmful to the eyes?

High-concentration ozone irritates the eyes and airways, so nobody may stay in the room during treatment, and the room must be ventilated for the time the technician sets before re-entry.

How do I fix a musty room after drying laundry indoors?

Rewash and sun-dry fabrics, ventilate, wipe mould spots and discard smelly mats. If odour remains, ozone in the empty room can help.

How much does ozone treatment cost?

It depends on area, rooms and condition. WHD quotes per job. Call 065-556-6294 or LINE @whd268.
