South Africa’s influenza season has begun. While many people recover from the flu within a week or two without needing medical intervention, the virus can lead to serious illness in high-risk groups, including older adults, pregnant women, and young children.
Even if you don’t fall ill, you can still carry and spread the virus to others, increasing the risk of widespread community transmission. This makes it essential for everyone to play a role in prevention by practicing proper hygiene, covering coughs and sneezes, and staying home when feeling unwell.
“The influenza virus is quick to adapt and constantly evolves to outsmart our immune defences,” explains Dr Michael de Villiers, a general practitioner at Netcare Medicross The Berg. “It’s a group of viruses that spreads very efficiently, lingering in the air or on surfaces long after contamination.” Typical flu symptoms include fever, body aches, fatigue, nasal congestion, and coughing – symptoms that can significantly interfere with work, school, or daily routines.
To combat the changing nature of the virus, scientists develop a new flu vaccine each year, targeting the most severe and common strains. While it’s not possible to include protection for every variant, the vaccine remains a key tool in reducing illness.
“The annual flu shot is especially important for those more likely to experience complications,” says Dr De Villiers. “That includes people with chronic health conditions, the elderly, pregnant women, and those working in healthcare or caregiving roles.”
Although the vaccine doesn’t offer total protection, it helps lessen symptom severity and shortens recovery time. “Think of it as preparing your immune army before the battle,” adds Dr De Villiers.
Most people with the flu benefit from rest, staying well-hydrated, eating nutritious foods, and using over-the-counter remedies where appropriate. Recovery typically takes about a week, though some symptoms may linger for up to 10 days. Dr De Villiers also advises against exercising while sick, especially with chest-related symptoms, as it could strain the heart and lead to serious complications.
If symptoms worsen – such as chest pain, rapid breathing, confusion, or persistent high fever – seek medical help immediately. In children, signs like blue lips, severe headaches, or unusual drowsiness should never be ignored.
