[Influenza: prevention and treatment]

Area of Science:

• Virology
• Epidemiology
• Immunology

Context:

• Influenza remains a significant public health concern, necessitating effective prevention and treatment strategies.
• Current vaccination guidelines for influenza have limitations, particularly regarding age cut-offs for at-risk populations.

Purpose:

• To review current strategies for influenza prevention and treatment.
• To discuss the potential benefits of lowering the vaccination age and expanding healthcare worker immunization.
• To evaluate the role of neuraminidase inhibitors in chemoprophylaxis and treatment.

Summary:

• Inactivated influenza vaccines are crucial for preventing severe illness in at-risk individuals.
• Lowering the vaccination age to 45 years is proposed based on mortality data.
• Immunizing healthcare workers is vital for patient safety and reducing absenteeism.
• Intranasal live attenuated influenza vaccines show promise, especially for children.
• Neuraminidase inhibitors may be effective for outbreak control and influenza treatment, potentially reducing antibiotic misuse.

Impact:

• Optimizing influenza vaccination strategies can mitigate the impact of epidemics.
• Enhanced immunization of healthcare workers can improve patient outcomes and healthcare system resilience.
• Further research into neuraminidase inhibitors could lead to improved influenza management and reduced antibiotic resistance.
