Sanitization & Fogging figures our articles draw on
- 98%
Aerobic colony counts fell 98% after added fogging compared with post-cleaning measurements.
Read with care: System-specific; commercial technology; no patient infection or occupied-room safety endpoint.
Source: Khandelwal et al. (2022)Patient-room surfaces sampled after standard cleaning and again after a specific fogging system.
- 81%
81% reported bleach use on high-touch surfaces in contact-isolation rooms.
Read with care: 47 of 273 contacted participated; practices were reported rather than observed.

- 19-21 million
Norovirus causes 19 to 21 million illnesses, about 2,500 reported outbreaks, 109,000 hospitalizations and 900 deaths in the United States each year.

How to use these articles
Where should I start if a fogging proposal just landed on my desk?
First read the article on red flags when hiring a company. Then read the one on questions to ask before hiring. Together they help you sort through a proposal quickly. If price is your main concern, follow with the articles on cost factors and comparing bids. When you are ready to act, use the Provider Vetting Checklist tool. It turns those questions into a list you can send to each company.
Which articles help most right after someone becomes ill in the building?
Start with the article on urgent situations and what to do first. It covers separating people, handling small spills, and calling the health department. Then read what to expect during a professional visit, so you know what a company should propose. The First 24 Hours Planner tool turns those early steps into an ordered list for your own situation.
I am worried about whether insurance will pay. Which article should I read?
Read the article on whether homeowners insurance covers sanitizing fogging. It explains why routine fogging, or fogging after an illness, is rarely covered. It also shows how fogging can be part of a bigger covered claim. It has a section for landlords, condo owners, and home-based businesses too. Then the Insurance Claim Organizer tool helps you build the file if an event might be covered.
How do the fogging articles help me answer the estimator's questions about my building?
The articles explain why steps matter, like cleaning first, how long the disinfectant must stay wet, and how long to wait before re-entry. The tools apply those ideas to your building. For example, the cost factors article explains what drives the price of a fogging treatment. The Cost Range Estimator lets you describe your floor space and rooms to see which drivers apply. Reading first makes the tool's questions easier to answer.
Do the articles replace advice from my health department or state agency?
No. The articles explain general practice and the questions to ask. But they cannot tell you what your local health department, licensing agency, or state pesticide agency requires. When an article mentions one of those offices, take it as a prompt to call them. Their advice for your own setting and situation always comes before general reading.
Are the examples in the articles real events?
No. The schools, daycares, offices, and homes in the examples are made-up blends. They were written to show how choices play out. They do not describe real clients, results, or prices. Use them to see how the steps fit together. Then apply the same thinking to your own building, product labels, and local advice.
How can I use these articles with staff or a board?
Pick the one or two articles that match the choice in front of you. Share them before the meeting instead of sending the whole library. The case study article and the property manager article work well for board talks. They show a full decision from start to finish. For cleaning and facilities staff, the articles on cleaning versus disinfecting and on safety risks are practical places to start.
