Well apparently most of those bacteria are perfectly harmless and some even postulate that they could be beneficial.

"I would advise any new parent to roll their child on the floor of the New York subway," Chris Mason, the author of the subway-pathogen study recently said at a public event.

“Some research has suggested that the idea could partially explain why children who grow up around animals and in rural areas appear to develop conditions like asthma less often than children who don't,” Business Insider explains. “And even for people other than young children, the hygiene hypothesis makes intuitive sense: After all, literally every surface in the world is covered in bacteria. The idea that things can be "perfectly clean" is a myth — humans need bacteria to live.”
