The True Story: A Two-Storey Home in Utah After 20 Days of Isolation

In June 2022, Utah health officials and the US Centers for Disease Control and Prevention (CDC) sampled a two-storey home where two people with mpox lived together and had isolated for 20 days. The team swabbed 30 objects and surfaces across 9 areas of the home.

• 21 of 30 samples (70%) had mpox viral DNA by PCR
• All 3 fabric items were positive: a couch and blanket, a chaise lounge and a bed blanket
• Positive hard surfaces included light switches, the toilet handle and seat, the fridge and ice dispenser handle, the coffee maker, the shower door handle, taps, the banister, computer mice and keyboards
• But no sample yielded viable virus in culture

The authors concluded that the virus may have decayed or been inactivated, and that the cleaning and disinfection the patients did themselves may have limited contamination. They noted the data were limited and called for more study.

What This Means for Families in Thailand

The finding has two sides. First, patients leave traces of the virus on almost every household item hands touch. Second, regular cleaning and disinfection may genuinely reduce the risk. That is why families with a member isolating at home should have a clear cleaning plan. In Thailand, mpox patients with mild symptoms may be advised to isolate at home at a doctor's discretion, so families should know which spots to look after. Ask the Department of Disease Control on the 1422 hotline.

Around the house

• Light switches, banister, mouse, keyboard, desk chair and medicine tubes

How to Care for Your Home While Someone Is Isolating

1. Follow your doctor's and public health officials' advice on how long to isolate
2. Give the patient a separate room and bathroom if possible
3. The patient disinfects the spots they touch often, if well enough, in line with the Utah findings
4. Cover the sofa with a washable cloth, or give the patient their own furniture
5. Keep a separate computer, mouse and keyboard, or disinfect them before others use them
6. Wash laundry in hot water, do not shake it, and wear gloves when handling the patient's linen

When Isolation Ends, What Should the Household Do?

1. Wash every fabric the patient used, including sofa covers and curtains
2. Clean dirt off surfaces first, then disinfect
3. Fog fabric furniture, mattresses and carpets, which cannot be washed whole
4. Disinfect the bathroom and high-touch spots throughout the home using the checklist above

How ULV Fogging Helps

The World Health Disinfection disinfection service uses ULV fogging machines that turn the disinfectant into a fine mist. It settles across the whole area, including corners, curtains, upholstery and surfaces that hand wiping cannot fully reach.

• Whole-area coverage without relying on wiping spot by spot
• Quick return to use, typically about 30 minutes after fogging
• The team wears full protective equipment, so owners and staff do not take the risk themselves
• Report and photos after the job to show customers, management or authorities
• Tax invoice with 3% withholding tax for companies and agencies
• More than 5 years of experience in hospitals, offices, hotels and public buildings

The Disinfectant We Use: Chemgene HLD4H

The team uses Chemgene HLD4H. According to WHD's product page, it meets the EN 14476 standard for virucidal activity, is used in NHS hospitals in England, and is endorsed by Mahidol University. We do not claim that Chemgene has been tested against mpox specifically. But mpox is an enveloped virus, which suitable disinfectants can inactivate when used at the manufacturer's stated concentration and contact time.

• No harsh bleach smell
• Works on many surfaces, from desks and counters to handles and equipment
• Can be bought for daily wiping of high-touch points

10 Reasons to Fog Your Home After an Mpox Patient Isolates

1. The Utah home had virus traces on 70% of items
2. Fabric furniture was positive in every item tested
3. The team wears protective equipment, so the household does not take the risk
4. It reaches corners that wiping cannot
5. It protects children and older people at home
6. It eases worry before returning to normal life
7. It uses a disinfectant that will not damage fabrics and furniture like strong bleach
8. It suits condos and rental rooms where owners want evidence
9. It helps prevent other germs at the same time
10. You can return home quickly

Before and After

Frequently Asked Questions

Q: Does finding viral DNA mean the virus can spread? A: Not necessarily. DNA does not mean live virus. No culturable virus was found in Utah, but the results show the virus can spread widely around a home. Q: When should we fog? A: After the patient has completed isolation and the sores have healed, before others use the room again. Q: Does Chemgene HLD4H kill mpox? A: It is not claimed to be tested against mpox specifically, but it meets EN 14476 for viruses, and mpox is an enveloped virus. Q: Can I use it on a keyboard and mouse? A: Use a cloth moistened with the disinfectant. Do not pour liquid directly onto electrical equipment.
