Flu 2026 in George: Symptoms, Vaccine, and When to See a GP

The 2026 flu season in South Africa

The National Institute for Communicable Diseases (NICD) declared the 2026 flu season open in week 11, the week starting 9 March. This is roughly four weeks earlier than the long-term average and similar to 2025's early start. RSV started in the same week, which is unusual: two respiratory virus seasons running together puts compounded pressure on clinics and hospitals, and many households are seeing successive viral illnesses through their children. The Western Cape Department of Health and Wellness has secured 105,000 public-sector doses for high-risk groups across the province. Cold and wet weather from the early-May Garden Route storm will further accelerate respiratory virus transmission over the coming weeks, particularly across George, Wilderness, Mossel Bay, and Knysna.

In March 2026 private-sector laboratory surveillance (PathCare and Ampath), influenza A positivity rose from around 10% to 13% through the month, reaching above 16% by week 13. Both A(H3N2) and A(H1N1)pdm09 are co-circulating, roughly 57% and 43% of typed influenza A samples respectively. Influenza B is also circulating, all of it Victoria lineage. H3N2-dominant seasons have historically driven higher hospitalisation and death rates, particularly in adults over 65.

The paediatric data is more striking. RSV positivity in babies under 1 year rose from 4.7% in February to 17.1% in March, and from 6.1% to 14.3% in 1 to 5 year-olds. Influenza A in school-age children (6 to 12 years) more than doubled in the same window, from 6.0% to 13.6%. Adenovirus is also circulating heavily in 1 to 5 year-olds (around 20% positivity).

Why flu is not just a bad cold

Each year in South Africa, roughly one in five people will have an influenza-associated illness. NICD burden estimates put this at around 10.7 million cases annually, with approximately 128,000 severe cases and 11,500 deaths.

Flu causes serious illness through several mechanisms:

• Direct viral pneumonia, which can progress rapidly in the first 48 to 72 hours
• Secondary bacterial pneumonia, often presenting as a "biphasic" illness where someone improves from flu and then deteriorates again with new fever, productive cough, and breathlessness
• Worsening of underlying heart, lung, or metabolic disease, particularly in older adults
• Hospitalisation and ICU admission complications including blood clots, sepsis, and rare but devastating neurological complications in children

International data from the 2024 to 2025 northern hemisphere season is sobering. Among hospitalised flu patients, around 89% had at least one underlying medical condition, 17% required ICU admission, and 3% died in hospital. In adults aged 75 and older, hospitalisation rates reached 599 per 100,000.

In South African data specifically, around 30% of flu-associated deaths in people aged 5 years and older occur in people living with HIV. TB is an independent risk factor as well. This pattern is one reason annual flu vaccination matters more here than in many other countries.

Who is at higher risk

NICD 2025 guidelines identify the following groups as priorities for vaccination and antiviral treatment:

• Adults aged 65 and older
• Children under 5, especially those under 1
• Pregnant women in any trimester, and women up to 6 weeks postpartum
• People living with HIV, regardless of CD4 count
• TB patients, current or recent
• Chronic conditions: asthma, COPD, cardiac disease (excluding uncomplicated hypertension), diabetes, chronic kidney or liver disease, neurological or neurodevelopmental conditions, haemoglobinopathies
• Immunosuppression: cancer, immunosuppressive medications, post-transplant
• BMI of 40 or higher
• Healthcare workers and residents of long-term care facilities
• Children on long-term aspirin therapy

If you are in any of these groups, you should be vaccinated annually and seen early if you develop flu symptoms. The risk is not just the flu itself; it is what flu does to the underlying condition you already have.

A practical note. Many patients underestimate their own risk. Mild-to-moderate COPD, well-controlled diabetes, or a medication like a biologic for inflammatory arthritis can place you in a higher-risk group without you realising it. A clinical assessment puts the picture together and decides whether vaccination, post-exposure prophylaxis, or early antiviral treatment is the right move for you.

Telling flu from a cold, RSV, or COVID-19

There is no symptom checklist that gives you a definite answer. Studies of community respiratory virus cases show heavy overlap between flu, RSV, common colds, and COVID-19. A few patterns help, though:

• Flu typically starts abruptly with fever, body aches, headache, and dry cough. Adults often describe feeling "knocked sideways" within hours.
• A common cold tends to be slower in onset, milder, and centred on the nose and throat without significant body aches or high fever.
• RSV in adults often looks like a heavy chest cold with wheezing, particularly in older or immunocompromised people.
• COVID-19 still circulates and can present with fever, cough, sore throat, and headache, sometimes with loss of smell.

Two practical implications follow. First, you cannot reliably self-diagnose. Second, the treatments differ. Antiviral medicine for flu does not work for any of the other respiratory viruses. Combined point-of-care tests for flu, RSV, and COVID-19 are now available and can guide treatment within minutes during a consultation at NeoHealth George.

Antiviral treatment: the 48-hour window

There is one widely used antiviral medicine for influenza, with a robust evidence base when started early:

• Started within 48 hours of symptom onset, the antiviral reduces illness duration by approximately one day in adults, reduces lower respiratory tract complications requiring antibiotics by 44%, and reduces hospital admissions by 63% in higher-risk patients
• Benefit is greatest in the first 48 hours but remains meaningful at 48 to 72 hours, particularly in older patients and those with comorbidities
• For severe, complicated, or progressive illness, treatment is started regardless of how many hours have passed

The clinical implication is simple. If you are in a higher-risk group and you develop flu symptoms, you should be seen promptly. Treatment is most effective when it starts early, and the decision to treat does not need to wait for a positive test result. NICD guidelines explicitly recommend starting antivirals based on clinical assessment when flu is circulating, rather than delaying for laboratory confirmation.

For otherwise healthy adults with mild illness, antivirals are not routinely recommended. Rest, fluids, paracetamol, and a clear plan for what to watch for are usually enough. The point of an early consultation is not to insist on a prescription; it is to risk-stratify accurately so that those who need treatment get it in time.

The flu vaccine at NeoHealth George

The 2026 Southern Hemisphere flu vaccine is trivalent. This change reflects the global disappearance of the B/Yamagata lineage of influenza B since 2020, after which the World Health Organization recommended dropping it from seasonal vaccines. The current formulation includes updated A(H1N1) and A(H3N2) components alongside the B/Victoria component.

Real-world effectiveness data from the 2025 Southern Hemisphere season, pooled across eight countries including South Africa, showed about 50% protection against medically attended flu illness and around 50% against hospitalisation. NICD's 2025 sentinel surveillance data showed similar numbers locally. This is in line with global expectations: a "moderately effective" flu vaccine still meaningfully reduces severe disease and hospitalisation in a high-burden setting like ours.

At NeoHealth in George Central we administer the trivalent flu vaccine during a brief vaccination consultation. This includes screening for contraindications (severe egg allergy, previous Guillain-Barré syndrome, active febrile illness), the injection itself, and basic post-injection observation. The vaccine is funded by most major medical aid schemes from the preventive benefit basket, typically without affecting your day-to-day or savings, and the cash price for self-paying patients is R250.

We do not administer routine childhood vaccines on the EPI-SA schedule (those are provided by state primary healthcare clinics). We do offer the seasonal flu vaccine for at-risk children from 6 months of age, and tetanus boosters for adults and children when clinically indicated.

When to bring your child in

Most children with flu recover at home with rest, fluids, and paracetamol. The reasons to bring a child in promptly are about identifying severe disease early, not about getting an antibiotic. Antibiotics do nothing for flu, and inappropriate antibiotic use causes more harm than good.

Get to a clinic or emergency department immediately if a child shows any of the following:

• Fast breathing: more than 50 breaths per minute in a child aged 1 to 5 years, or more than 40 in older children, when calm and resting
• Chest retractions, where the skin pulls in with each breath, or nasal flaring
• Pauses in breathing, blue or pale lips or fingernails
• Inability to drink or breastfeed, or persistent vomiting
• Fewer than four wet nappies in 24 hours, or signs of dehydration in older children
• Unusual drowsiness, floppiness, or difficulty rousing
• New confusion, an unsteady gait, abnormal movements, or a seizure
• A child who improved and then got worse again after several days

Approximately half of paediatric flu deaths internationally occur in children with no known underlying medical condition. Healthy children can develop fulminant flu, including rare but devastating complications such as influenza-associated encephalopathy. This is the rationale for an early in-person review in any child with significant flu symptoms, rather than reflexive home management.

For children under 5, particularly under 1, and for any child who is HIV-exposed, premature, or has a chronic lung, heart, or neurological condition, we have a low threshold for in-person review.

When to come in for adults

Same day:

• High fever with severe body aches, dry cough, and feeling profoundly unwell
• Symptoms in a higher-risk group (any of the categories above)
• Symptoms in pregnancy
• Symptoms with shortness of breath at rest, chest pain, confusion, or dehydration
• Sudden re-deterioration after seeming to improve

Within the week:

• Mild to moderate symptoms in an otherwise healthy adult that are not improving by day five
• A persistent cough four weeks after the acute illness, particularly with weight loss or night sweats (this needs evaluation for TB and post-viral complications)
• Concerns about household members at high risk who may need post-exposure consideration

After exposure: can antivirals prevent flu?

If a household member has confirmed flu and you are at high risk for severe disease (older, pregnant, immunocompromised, on chronic medication for a major condition), there is a 48-hour window after exposure during which an antiviral medicine taken preventively can substantially reduce your risk of becoming ill yourself. International data shows household transmission rates of 12 to 17% without this preventive course, dropping to about 1% with it.

This is a clinical decision, not a "just in case" prescription. We weigh your vaccination status, the type and duration of contact, your risk factors, and the timing. If it's appropriate, we prescribe a 10-day course at the prophylaxis dose. If not, we focus on early symptom recognition and rapid review if anything develops.
