A literature review of influenza chemoprophylaxis and treatment in children.

Influenza remains a common cause of hospitalization among children, bringing substantial morbidity and mortality rates. Despite its soaring prevalence, a significant gap in therapeutic interventions persists, especially for the pediatric population. We present a literature review detailing clinical trials or case reports published in the last six years (since 2019) that discuss the prevention or treatment of influenza in children. We used search engines such as PubMed or Cochrane Library. All studies/case reports are written in English, and all the clinical trials are finished. In Europe, oseltamivir, zanamivir, and baloxavir marboxil are recommended for the treatment or prophylaxis of influenza in adults and children, while the Food and Drug Administration added intravenous peramivir to the list of anti-influenza drugs. Oseltamivir remains the first line of treatment and chemoprophylaxis. However, there are still discussions related to the duration of prophylaxis, with shorter periods of administration being explored, or the most efficient treatment dosage program (whether it is the conventional dosage of 3 mg/kg/dose for children <40 kg or 75 mg for adults, twice daily, compared to a double dosage administration program). When faced with an old disease, it is essential to constantly assess the efficacy of conventional molecules and dosages, along with new antivirals or complementary medication.
