Hong Kong Flu Season: What to Know, Flu Symptoms & Immune Support Tips

Hong Kong's 2026 flu season began in late June and is currently running at "high to very high" activity, according to the Centre for Health Protection (CHP). If you've noticed more coughing on the train or classmates or colleagues calling in sick, this is why.

Hong Kong is Currently in an Active Influenza Season

Earlier surveillance showed influenza A as the predominant type circulating in Hong Kong, including both H3 and H1 viruses, alongside influenza B. 

This is particularly relevant in Hong Kong because everyday life involves a lot of close contact — from packed MTR trains and buses to schools, shopping centres, offices and restaurants.

What Are the Common Flu Symptoms to Watch For?

Severe Cases Are Already Being Reported This Season

As of mid-September, CHP surveillance data show over 614 severe influenza cases across all age groups this season, including more than 390 deaths. Most severely affected adults had underlying health conditions. Still, CHP has also confirmed cases among previously healthy children and adults — a reminder that flu can turn serious for anyone, not only the already-vulnerable.

The point isn't to alarm you. Protection needs to be in place before exposure happens.

Vaccination and Good Hygiene

The 2026/27 Seasonal Influenza Vaccination (SIV) Programmes officially launched on September 17, 2026. CHP strongly recommends the seasonal flu vaccine as the most effective way to lower your risk of infection and complications. Eligible individuals can get free or subsidised vaccinations through these programmes. 

Good hygiene habits still matter alongside vaccination:

• Wash your hands regularly

• Avoid touching your eyes, nose and mouth with unwashed hands

• Wear a mask when you have symptoms or are in crowded places

• Keep indoor spaces well ventilated

• Stay home from school or work if you're unwell

• See a doctor if symptoms are severe or getting worse

Why Daily Immune Support Matters During Flu Season

Vaccination and hygiene lower your risk of exposure, but they don’t stop there. Once your body does encounter a virus, how well it responds depends on your immune system's day-to-day readiness, not just what you do on the days you feel sick.

Your immune system is a complex network of cells and processes working together, built up through consistent daily habits: a balanced diet, enough sleep, regular movement — and where diet falls short, targeted nutritional support.

This is where BElixz SHIRUTO fits in. It's formulated to support your body's natural defenses every day, so they're ready when it matters most during a season like this one.

The Takeaway for Hongkongers

Flu season shouldn't only become a priority once someone gets sick. With activity currently high, now's a good time to review your family's habits — get vaccinated, keep up good hygiene, and give your body daily immune support through balanced nutrition and BElixz SHIRUTO.

Take care of your health before the next wave hits — because in Hong Kong, staying well means keeping up with a city that never slows down.
