Perhaps. But the other side of the coin is, a more health guts is also possible from such exchanges. I would imagine it's going to depend on who you associate with and their gut health. For example, studies have shone that people who are married generally live longer*. Is that from companionship or the exchange of microbes? Moi? I'm curious to know the affects of the pandemic isolation / lock downs on collective gut health. Did the attempts to prevent the spread of the virus help or hinder gut health? I suspect the latter, if only because the lock down violates evolution. * People with dogs also live longer, which raises the same question.
