As South Africa’s influenza season has commenced, many might view flu as merely a bad cold. However, the true scope of flu’s impact on our health, our families, and our communities extends beyond typical seasonal discomfort. It’s a preventable illness that, when not adequately addressed, can lead to significant health challenges and hospitalisations. With the 2026 flu season already ongoing, proactive steps and prevention efforts remain an important way to protect well-being and sustain daily routines.
Understanding the Flu
Despite being vaccine-preventable, flu is often overlooked, under-recognised, and frequently confused with the common cold. Yet it carries a more substantial health impact. It begins abruptly, often with a high fever (≥38.3°C) – a symptom less common in colds – and can lead to notable seasonal increases in medical interventions and hospital admissions. South African surveillance by the National Institute for Communicable Diseases (NICD) highlights flu as a notable health consideration, with a detection rate of 10.4% in 2025¹.
For certain vulnerable groups, the health implications are considerably higher, potentially transforming what might be a temporary inconvenience for some into a more serious health event for others. Each year, an estimated 6,000 to 11,500 individuals in South Africa experience flu-related complications that, sadly, can be fatal².
This risk is particularly elevated for:
- The elderly (65+), accounting for about half of all flu fatalities.
- People living with HIV (PLWH), representing a notable 30% of flu-related deaths.
- Pregnant women, young children, and those with chronic illnesses (like diabetes, hypertension, heart or lung disease), all of whom face a significantly increased potential for severe health outcomes.
Clarifying Common Flu Misconceptions
Misconceptions can sometimes contribute to lower vaccination rates and a less cautious approach to the flu. By understanding the facts, we can make informed decisions about our health.⁴ One common belief is that flu is a mild illness, akin to a common cold, and therefore doesn’t require vaccination. Flu is distinctly more impactful than a cold, causing high fevers and potentially leading to more serious health issues². Vaccination is a crucial preventative measure against this more challenging virus.
Another misconception suggests that only children need a flu shot. Annual flu vaccination is recommended for all age groups. While children are more prone to flu infection, adults, particularly those with underlying conditions, also experience higher rates of severe flu complications. Protecting adults helps reduce transmission, benefiting everyone. South African data shows low uptake among older adults (32.3%), despite evidence of significant hospitalisation risk reduction among this group³.
Furthermore, many believe that last year’s flu shot offers continued protection.¹ However, flu viruses mutate annually, which is why the World Health Organization (WHO) updates the vaccine composition each year to match circulating types. Immune protection also naturally declines over time. Annual vaccination helps ensure the best possible match and optimal protection against the latest circulating viruses, with recent vaccine effectiveness demonstrating good protection, for example, around 51.3% in 2025¹. These factors contribute to relatively low vaccination rates (less than 3% among adults) in South Africa.³
The Personal & Community Power of Prevention
For a nation focused on growth and resilience, prioritising preventative health measures like flu vaccination means empowering individuals to live more fully and participate actively in society. “Flu prevention is fundamental to public health because it directly impacts both individual well-being and community resilience. When people can maintain their health and avoid serious illness, they are better able to pursue their daily activities and remain actively involved in their families and communities,” says Dr Karmani Murugan, Medical Manager at Abbott.
Your Path to Protection This Winter
The annual flu vaccine remains the single most effective tool for safeguarding our health and ensuring we can be present for what matters most. It’s readily available across South Africa at most local pharmacies and general practitioners (GPs). Many employers also offer vaccinations through corporate wellness programmes.
Beyond vaccination, a multilayered approach to prevention is key, and aligned with guidance from the National Department of Health⁴:
- Wash hands frequently (20 seconds minimum).
- Avoid close contact with sick individuals.
- Avoid touching your eyes, nose, or mouth.
- Stay home when unwell.
- Maintain good respiratory hygiene (e.g., covering coughs and sneezes).
Annual flu vaccination helps prevent complications, reduces hospitalisations, and contributes to protecting vulnerable communities, helping us all lead healthier, more connected lives. The ongoing and evolving nature of the flu challenge makes proactive prevention efforts especially critical for the well-being of individuals and the strength of our communities.
