General health information. Follow current local public-health and clinical advice.
Use local information for local decisions
Seasonal influenza is a respiratory infection caused by influenza viruses. A report from one country or hemisphere does not establish the level of activity in another. Check the date and location of any surveillance report, and avoid interpreting an old comparison of case numbers as a prediction of how severe the current season will be.
Discuss vaccination through the appropriate service
WHO identifies vaccination as an important way to prevent influenza and reduce its impact. Vaccine recommendations and available products depend on the country, age group, and individual circumstances. A local clinician or vaccination service can help you follow the current programme. Do not assume that a product mentioned in an overseas article is available or suitable for everyone.
Make ordinary preparation easier
Follow public-health advice on respiratory hygiene and reducing spread when unwell. Keep practical arrangements for rest, work, and caregiving in mind before illness disrupts a routine. Seek medical advice when symptoms are concerning or when a person has particular risk factors. This overview does not diagnose symptoms or provide a medication plan.
