This open-label study will assess the pharmacokinetics and safety of oseltamivir [Tamiflu] in 3 cohorts of infants, aged 0-30 days, 31-90 days and 91-<365 days with influenza infection. Patients will receive 10 doses of intravenous oseltamivir [Tamiflu] therapy over 5 or 6 days. Optional oral therapy with oseltamivir [Tamiflu] may be considered following the intravenous dose associated with pharmacokinetic blood sampling. Evidence of continued virus shedding at day 6 can allow for up to 5 additional days (10 doses) of oral or intravenous administration. Anticipated time on study drug is 5-11 days. Target sample size is <50 patients.

Primary Outcome Measures:
  • Steady-state pharmacokinetics parameters AUC0-12 and Cmax of oseltamivir and oseltamivir carboxylate [ Time Frame: Multiple sampling day 3 or 4 ] [ Designated as safety issue: No ]
  • Safety Profile: AEs, vital signs, laboratory parameters [ Time Frame: Days 1-11 and on follow up days 15 and 30 ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Viral load and shedding [ Time Frame: Assessment days 1, 3 or 4, 6, 11, and optional at days 15 and 30 ] [ Designated as safety issue: No ]
  • Development of resistance to oseltamivir [ Time Frame: Assessment days 1, 3 or 4, 6, 11, and at days 15 and 30 if samples are collected ] [ Designated as safety issue: No ]
