Vandvik PO, Agarwal A, Rylance J, et al. Summary of WHO clinical practice guidelines for influenza. BMJ. 2026 Feb 27;392:e087397. doi: 10.1136/bmj-2025-087397. (Evidence-based guideline)
Abstract

ABOUT THIS GUIDELINE: This BMJ Rapid Recommendation is a summary of a World Health Organization guideline published 12 September 2024. The full guideline is available in MAGICapp and in PDF on the WHO website. The WHO guideline is primarily for healthcare providers and takes a patient-centred perspective on benefits and harms. Other considerations include resource implications, acceptability, feasibility, equity, and human rights of relevance to healthcare systems. Recommendations were developed according to standards and methods for trustworthy guidelines by a panel of non-conflicted experts, as delineated in the WHO handbook (https://www.who.int/publications/i/item/9789241548960).

CLINICAL QUESTIONS: What is the role of medications in treating non-severe and severe influenza including zoonotic disease (novel influenza A), and in preventing infection among contacts? Which diagnostic testing strategies best enable rapid and accurate treatment decisions?

CONTEXT AND CURRENT PRACTICE: New randomised controlled trial (RCT) evidence, ongoing concerns about zoonotic disease, and the increasing availability of rapid diagnostic tests require updated guidance.

RECOMMENDATIONS: apply to seasonal influenza and zoonotic influenza. There are 29 recommendations; 21 related to antiviral medications and six to adjunctive therapies to prevent and treat influenza. Recommendations are stratified by severity of disease and risk of disease progression. For seasonal influenza, WHO conditionally recommends treatment within 48 hours of symptom onset with oseltamivir for severe illness, and baloxavir for patients at high risk of progression from non-severe to severe illness. WHO also conditionally recommends prophylaxis (using baloxavir, laninimavir, oseltamivir, or zanamivir) for anyone exposed to zoonotic influenza, and for those exposed to seasonal influenza who are at extremely high risk. The panel issued recommendations against the use of adjunctive therapies in patients with non-severe influenza (strong recommendation against antibiotics) and severe influenza (conditional recommendation against corticosteroids, macrolides, mTOR inhibitors, non-steroidal anti-inflammatory drugs, and passive immune therapy). A recommendation is made for diagnostic testing strategies in non-severe and severe influenza disease.

THE EVIDENCE: Four systematic reviews of RCTs provided low to very low certainty evidence on benefits and harms of antiviral medications and adjunctive therapies. A systematic review of prognostic factors provided baseline risk estimates and information on individual risk factors for disease progression. A decision analysis model informed recommendations for testing based on alternative potential diagnostic pathways.

It was very difficult to read and ascertain the relevant information for clinical practice in these guidelines. The recommendations are likely valuable, but the presentation in this document aren't.

General Internal Medicine-Primary Care(US) rater

This review article on treating moderate and severe influenza recommends that patients with moderate risk receive oselatamir at about $30 per course and patients at high risk get baloxavir for $200 per course. These recommendations are to decrease hospitalizations and mortality and should be started as soon as the diagnosis of influenza is suspected.

General Internal Medicine-Primary Care(US) rater

I doubt many providers in the US are aware of the recommendation to use baloxavir for non-severe influenza.

Infectious Disease rater

A concise review of the WHO statement regarding treating influenza.

Infectious Disease rater

The format and content of this article are very useful in supporting decision-making regarding therapeutic and prophylactic antiviral medications for influenza. It is very valuable to the practice of infectious disease specialists.

Internal Medicine rater

This is a common cause of hospitalization and death. Any evidence-based update on therapeutics is worthwhile.

Internal Medicine rater

As an internist who practices in clinic and the hospital, a significant portion of my patients have influenza. This is a useful summary.

This guideline does not adress the needs of GPs in ambulatory care. The proposed clinical pathway has nothing to do with current treatment and available treatment options in the real world.
