25% of antibiotics prescribed in the US are unnecessary

From the article, "The US Centers for Disease Control and Prevention estimates that about one third of all antibiotic prescriptions in the US are unnecessary"

In another study, "The researches grouped the diagnostic codes into categories by whether they “always,” “sometimes,” or “never” merited antibiotics... Of those, 23.5% of these prescriptions were given for ailments in the “never” category"

I would be interested to hear the ratio in other countries, my father who spends time in Taiwan mentioned that they subscribe antibiotics for almost everything, almost as we do for acetaminophen or Asprin.

Wonder if the study took into account secondary infections. ear aches or rattling in the chest, sinus infections ?

Only 25%?
