This study from the American Society of Microbiology specifically demonstrates how air driers at least add 3 bacterial colonies, and up to 254 colonies, when using an air drier in a public restroom: https://journals.asm.org/doi/10.1128/aem.00044-18. In addition, a Harvard review of the research also identifies that the chances of picking up a serious pathogen in the bathroom are quite small.

So, having little chance in general yet using the air drier, which has shown to add bacteria to your hands in every single test, doesn’t make sense after understanding this data. I’m a man of science, and this involves assessing all available data regarding the topic at hand. This being the case, the data provided above highlights how just not touching your face and washing your hands at the next opportunity after leaving a bathroom with only hand driers is the most logical move. But to each their own, I know microbiologist and virologist who are much smarter than I that refuse to use air driers, so I took note and make moves accordingly.
