Popis: Abstract Background In a previous retrospective observational study, a 3-day regimen of oseltamivir as post-exposure prophylaxis (PEP) for preventing transmission of influenza in wards was shown to be comparable to 7- to 10-day regimens provided index cases were immediately separated from close contacts. In order to confirm the efficacy of a 3-day regimen, we started to conduct a prospective, multi-center, single-arm trial. Methods This study is a prospective, multi-center, single-arm study designed by the Sectional Meeting of Clinical Study, Japan Infection Prevention and Control Conference for National and Public University Hospitals. Index patients with influenza are prescribed a neuraminidase inhibitor and are discharged immediately or transferred to isolation rooms. The close contacts are given oseltamivir as 75 mg capsules once daily for adults or 2 mg/kg (maximum of 75 mg) once daily for children for 3 days as PEP. All close contacts are monitored for development of influenza for 7 days after starting PEP. Discussion A 3-day regimen of oseltamivir as PEP has advantages over 7- to 10-day regimens in terms of costs, medication adherence and adverse effects.
