Why is the flu season starting early this year?
The flu season is beginning earlier due to the rapid spread of a mutated H3N2 subclade K strain. This variant has changed enough to partially evade current vaccines, leading to increased infections and hospitalizations. Additionally, factors like reduced vaccination rates and international travel have contributed to the early surge.

How dangerous are the current flu and norovirus outbreaks?
Both the flu and norovirus are causing significant health concerns this season. The flu, especially with the new H3N2 strain, is leading to more severe cases and hospital admissions, particularly among vulnerable groups like children and the elderly. Norovirus cases are doubling nationwide, causing severe gastroenteritis that can lead to dehydration and hospitalization if not managed properly.

What can I do to protect myself and my family?
Getting vaccinated remains the best defense against the flu, even with reduced effectiveness. Practicing good hygiene, such as frequent handwashing with soap and water, avoiding close contact with sick individuals, and disinfecting surfaces can help prevent norovirus and flu spread. Staying home if you’re feeling unwell and seeking medical advice early are also crucial steps.
-
Are current flu vaccines effective against the new strain?
The current flu vaccines are less effective against the mutated H3N2 subclade K strain, which has evolved beyond the vaccine’s target. While they may not fully prevent infection, vaccination can still reduce the severity of illness and the risk of complications. Health officials recommend getting vaccinated to provide some level of protection.
-
Should I be worried about the severity of this flu season?
Yes, health experts warn that this could be a particularly severe flu season due to the early start, the mutated virus, and the surge in norovirus. Hospitals are preparing for increased admissions, and public health officials emphasize the importance of vaccination and hygiene measures to mitigate the impact.

How long will this early flu and norovirus surge last?
While it’s difficult to predict exact timelines, health authorities suggest that the peak of the flu and norovirus outbreaks could last several weeks into winter. Staying vigilant, practicing good hygiene, and getting vaccinated can help reduce your risk during this period.
