This winter, health experts are seeing an unusual early surge in flu cases, especially in Scotland, driven by a mutated H3N2 strain. Many are wondering why the flu season is starting sooner than usual and what it means for public health. In this page, we explore the reasons behind the early rise, how health services are preparing, and what you can do to stay safe this winter.
-
Why are flu cases rising so early this year?
The early increase in flu cases is mainly due to a mutated H3N2 strain that is spreading rapidly. Factors like reduced immunity from last year's pandemic and delays in vaccination campaigns have also contributed to the early surge. This combination has led to more hospital admissions and increased pressure on health services.

How are health services preparing for a tough winter?
Health services are ramping up vaccination efforts, especially targeting vulnerable groups. Hospitals are also preparing for increased admissions by expanding capacity and ensuring adequate supplies of antiviral medications. Public health campaigns are emphasizing the importance of vaccination and good hygiene to prevent the spread.

What is the current status of global TB control efforts?
Globally, TB cases have declined slightly, which is a positive sign. However, funding cuts, particularly after the US withdrew support, threaten to reverse these gains. Experts warn that without sustained investment, TB control efforts could falter, leading to more cases and setbacks in eradication goals.

How can I protect myself from flu and TB this winter?
The best way to protect yourself is to get vaccinated against the flu and practice good hygiene, like washing hands regularly and avoiding close contact with sick people. For TB, if you are at risk or living in high-incidence areas, seek medical advice and consider screening. Maintaining a healthy immune system through proper nutrition and sleep also helps.
-
Is the flu vaccine effective against the new strain?
While flu vaccines are updated annually to match circulating strains, the mutated H3N2 strain has posed challenges. Vaccination still offers significant protection against severe illness and hospitalization, but effectiveness may vary. Health authorities continue to monitor and update vaccine formulations accordingly.

What are the signs of severe flu or TB infection?
Severe flu symptoms include difficulty breathing, chest pain, high fever, and confusion. For TB, symptoms like persistent cough, weight loss, night sweats, and fatigue are common. If you experience these, seek medical attention promptly to prevent complications.
