The expert explains which diseases can be transmitted if you flush the toilet with the toilet lid open

Flushing the toilet after using the toilet seems to be a simple and routine task. But do the shooting with the lid open is harmful and can generate serious health risks by spreading particles of water, urine, feces and waste into the air, a phenomenon known as the “aerosol effect”.




When the flush is flushed, the force of the water creates a fine spray that can contain bacteria, viruses and other pathogens found in the waste. These particles can spread throughout the bathroom, contaminating nearby surfaces such as toothbrushes, towels and other personal hygiene items.

“This risk is particularly relevant in environments where multiple people use the same toilet, increasing the chances of disease transmission. Therefore, it is recommended to close the lid before flushing to minimize the dispersion of these contaminants into the air,” explains pharmacist Margareth Wedge.
