I'm so confused by this take. Are you saying that washing your hands isn't an effective infection mitigation strategy? That is 100% proven empirical fact. That is literally the most effective thing that you can do to prevent ANY infection. If you're saying that just washing your hands doesn't prevent you from transferring microbes from contact fomites during facial contact, yes, you also have to avoid touching your face. Fellow health care workers know this can be one of the most difficult things in the world to get used to, but you have to make a conscious effort to avoid doing so until you break the habit. That doesn't make hand hygiene an ineffective practice though.
