In the project, PandemicClean – Safe and Effective Cleaning in Pandemic Situation, research findings will be gathered about factors affecting professional cleaning in a pandemic situation. During the three-year project at least 30 research will be documented.
This is the first research summary.

Toilets – the source of viruses
Abney, S.E. et al. 2021. Toilet hygiene—review and research needs
The goal of good toilet hygiene is minimizing the potential for pathogen transmission. Control of odours is also socially important and believed to be a societal measure of cleanliness. Understanding the need for good cleaning and disinfecting is even more important today considering the potential spread of emerging pathogens such as SARS-CoV-2 virus. While the flush toilet was a major advancement in achieving these objectives, exposure to pathogens can occur from failure to clean and disinfect areas within a restroom, as well as poor hand hygiene. The build-up of biofilm within a toilet bowl/urinal including sink can result in the persistence of pathogens and odours. During flushing, pathogens can be ejected from the toilet bowl/urinal/sink and be transmitted by inhalation and contaminated fomites.
We made short notice about research and full article link is below.
•Viruses were found
- In 78 % of surface samples
- In 62 % of flush handle samples
- In 52 %of lid samples
- In 59 % of toilet seat ring samples
- In 66 % of door handle samples
- In 81 % of air samples
- In 89 % of bowl water samples
•If the lid is up when flushing
- Microbes can be found 0-25 cm above the toilet seat ring and 0-15 cm around the toilet seat
•The origin of many infections has proved to be a toilet, caused by e.g.
- In a seeded toilet experiment salmonella was found in bowl water after 5 days and isolated from the biofilm below the water line in the bowl for up to 50 days
