There is a very specific silence that settles over Africa in winter.
It’s in the dark mornings where your alarm suddenly feels offensive. It’s in the taxis filled with coughs and sniffles. It’s in the office, a colleague insisting they are “fine” while visibly fighting for their life over a cup of coffee and cough syrup. And every year, many people make the same mistake: treating the flu like it is just “a bad cold”.
But doctors warn the 2026 flu season is already underway, and the consequences of ignoring prevention can ripple far beyond a few miserable days in bed.
According to the National Institute for Communicable Diseases (NICD), influenza remains a significant seasonal health threat in South Africa and other countries, particularly for older adults, pregnant women, people living with HIV and those with chronic illnesses.
That is why health experts say prevention matters now more than ever.
According to Dr Karmani Murugan, medical manager at Abbott, flu prevention is fundamental to public health because it directly impacts both individual well-being and community resilience.
Winter creates the perfect environment for viruses to spread.
People spend more time indoors with windows closed; ventilation decreases and close contact increases. Add exhausted immune systems, cold weather and stress to the mix and flu viruses spread quickly through homes, schools and workplaces.
Unlike the common cold, influenza often arrives suddenly and aggressively. One day, you are functioning normally. Next, your body feels like it has been hit by a truck. Fever. Chills. Body aches. Crushing fatigue. Persistent coughing. Headaches that sit behind your eyes like pressure.
For vulnerable groups, complications can become severe. Each year, thousands of flu-related deaths occur in South Africa, with elderly people and immunocompromised individuals facing the greatest risk.
Research also shows flu-related hospitalisation rates remain particularly high among people living with HIV.
Yet despite this, flu vaccination uptake among adults remains critically low.
Part of the problem is misinformation. Many still believe flu is harmless or that last year’s vaccine still protects them, but influenza viruses mutate constantly, which is why the World Health Organization updates vaccine formulations annually to match circulating strains.
5 essential flu prevention steps you should not ignore this winter
1. Get the flu vaccine early
Health experts continue to stress that annual flu vaccination remains the most effective protection against severe illness and hospitalisation.
The vaccine does not just protect you. It also protects vulnerable people around you, including elderly relatives, newborns, pregnant women and people with weakened immune systems. Think of it as community care in action.
2. Stop treating rest like a luxury
One of the biggest modern health problems is that people push through illness instead of recovering properly.
Sleep deprivation weakens the immune system significantly. Chronic stress does too. Your body cannot fight effectively when it is already exhausted. Rest is not laziness. It is biological maintenance.
3. Wash your hands more than you think you need to
It sounds basic because it works.
Flu viruses spread through droplets and contaminated surfaces constantly touched throughout the day, such as phones, keyboards, door handles, trolley handles and petrol pumps. Proper handwashing with soap for at least 20 seconds remains one of the simplest and most effective prevention tools available.
4. Protect your body with immune-supporting habits
Winter survival is not about expensive wellness trends. It is often about consistency.
Doctors recommend prioritising hydration, nutritious meals, movement and reduced alcohol consumption during flu season. Foods rich in vitamin C, zinc and antioxidants can help support immune function.
And yes, your grandmother was right about soup.
5. Stay home when you are sick
Perhaps the most overlooked form of care is staying away from others when you are unwell.
Many people still wear “working through sickness” like a badge of honour. But showing up sick at work, school or social events increases transmission and places high-risk individuals in danger.
Resting at home protects your recovery and your community. — iolnews.com
