ABSTRACT
PURPOSE OF REVIEW: The heavily suppressed global influenza activity during the coronavirus disease 2019 (COVID-19) pandemic is expected to return upon relaxation of travel restriction and nonpharmaceutical interventions (NPI). We reviewed the four marketed neuraminidase inhibitors (NAI e.g., oseltamivir, zanamivir, peramivir, laninamivir) and the only endonuclease inhibitor (baloxavir) on their clinical therapeutic effects and the ability of viral suppression in various groups of patients of different clinical settings based on the latest evidence.
RECENT FINDINGS: Early initiation, preferably within 48 h of symptom onsets, of antiviral treatments with NAI and baloxavir, is crucial to produce favourable outcomes in patients with influenza infection. Updated evidence does not suggest routine use of combined antiviral agents in patients with influenza infection. Treatment-emergent resistant influenza variants may occur during NAI and baloxavir use, but it has no major impact on subsequent recovery. Early treatment of index patients with influenza infection and post-exposure prophylaxis in specific populations is crucial in preventing influenza transmission.
SUMMARY: Antiviral therapy is the major defence therapeutically in the community and hospital settings to expedite early recovery and reduce influenza-related complications. Early treatment of index patients and post-exposure prophylaxis in susceptible close contacts may mitigate the spread of infection.
