This year's flu season in the US is hitting levels not seen in nearly 30 years. With rising cases, hospitalizations, and deaths, many are wondering what makes this season so severe. The emergence of a new H3N2 subclade K strain is a key factor, along with changes in vaccine effectiveness and public health policies. Below, we explore the reasons behind this intense flu season and what you can do to stay safe.

What makes this flu season so severe?
This flu season is considered the worst in decades mainly because of the emergence of a new H3N2 subclade K strain. This variant has led to higher infection rates and more hospitalizations, especially among vulnerable groups like children and older adults. Additionally, the vaccine's effectiveness has been reduced due to strain mismatch, making it harder to prevent infections.

What is the H3N2 subclade K strain?
The H3N2 subclade K strain is a new mutation of the flu virus that has recently become dominant in the US and internationally. It differs from previous strains and is less well-covered by current flu vaccines, which contributes to the higher number of cases and severe outcomes seen this season.
-
Should I still get vaccinated despite lower effectiveness?
Yes, health experts strongly recommend getting vaccinated even though the current flu shot may be less effective against the new strain. Vaccination can still reduce the severity of illness, prevent hospitalizations, and protect vulnerable populations. It remains a key tool in managing the flu season.
-
When will the peak of this flu season hit?
According to health officials, the peak of this flu season is still ahead. Cases and hospitalizations continue to rise, and experts warn that the worst period may occur in the coming weeks. Staying vigilant and following public health advice is crucial during this time.
-
Why did the government stop recommending flu vaccines for children?
The government recently shifted its policy, citing concerns over vaccine efficacy and the strain mismatch. Some experts warn that this decision could lead to worse outcomes for children, who are typically vulnerable to severe flu complications. The CDC still recommends vaccination for all children over six months old, despite these policy changes.

How can I protect myself during this severe flu season?
To stay safe, get vaccinated if you haven't already, practice good hygiene like frequent handwashing, avoid close contact with sick people, and wear masks in crowded places. If you develop flu symptoms, seek medical advice promptly to manage your health effectively.
