It is known that after flushing the toilet, some of the microbes fly away.
This is one of the reasons why you need to close the lid - this way the germs remain under the lid.
Otherwise, pathogens can be sprayed over a distance of 150 cm or more, resulting in contamination of walls and other surfaces.
Even after cleaning with a brush, significant dirt remains - it is important to use disinfectants.
Using a disinfectant and a toilet brush will reduce toilet contamination by 99.99%.
A closed lid simply changes the direction of the spray of viruses - this simply results in the microbes settling in a different place.
Regular cleaning is especially important for public toilets, so it is important to be extra careful in such areas.
