Antibiotic resistance may diminish the overall efficacy of antibiotics, thus, it is strongly advised to follow-up patients to determine whether initial treatment was effective [33, 35, 39]. Clarithromycin is therapeutically equivalent to other antibiotics studied and is associated with a better bacteriological eradication and a lower risk for related adverse events in children [49]. In general, no isolation measures are necessary. Parents or mother and her sexual partner should be evaluated and treated if needed.
