From when it starts to how to protect yourself this winter
Flu season in South Africa tends to sneak up on us — one minute it’s just a drop in temperature, the next you’re bundled up with a sore throat, body aches, and a nagging cough. But while the flu might feel unpredictable, there’s plenty you can do to prepare and protect yourself.
Here’s what to know about flu season in South Africa — including when it hits, how to tell the difference between a cold and the flu, and how to stay one step ahead.
When does flu season start in South Africa?
South Africa’s flu season typically begins in May and continues through August, often peaking during the coldest winter months of June and July. Colder weather pushes people indoors, which makes it easier for flu viruses to spread — especially in schools, workplaces, and busy public spaces.
Each year, the National Institute for Communicable Diseases (NICD) monitors circulating flu strains and recommends updates to the annual flu vaccine to keep up with any changes.
Should you get the flu vaccine?
While it’s a personal decision, getting the flu vaccine is strongly encouraged — especially if you’re in a high-risk group. These include:
- Children under 5
- People over 65
- Pregnant women
- Anyone with chronic conditions like asthma, diabetes, or heart disease
- Healthcare workers
- Those with weakened immune systems
Even if you’re healthy, the flu can still leave you feeling wiped out for days — and the vaccine helps reduce both the severity and the spread of the illness.
Cold or flu? How to tell the difference
The flu and the common cold share similar symptoms, but there are a few key differences:
| Symptom | Cold | Flu |
|---|---|---|
| Onset | Gradual | Sudden |
| Fever | Rare | Common (high) |
| Fatigue | Mild | Intense |
| Body aches | Rare | Common |
| Chills & sweats | Rare | Common |
| Headache | Uncommon | Common |
| Runny/stuffy nose | Common | Sometimes |
| Sore throat | Common | Sometimes |
If symptoms appear suddenly and hit hard, there’s a good chance it’s the flu.
What to do if you catch the flu
If the flu hits, the best thing you can do is rest and focus on recovery:
- Stay home to avoid spreading the virus
- Rest and give your body time to heal
- Drink plenty of fluids to stay hydrated
- Manage symptoms with paracetamol or flu meds
- See a doctor if you’re in a high-risk group or symptoms get worse
Some clinics, such as M-KEM in Bellville, offer extended hours and walk-in doctor consultations for those needing extra support during flu season.
Stay prepared this flu season
Flu season doesn’t have to catch you off guard. A little planning — whether it’s getting vaccinated, stocking up on essentials, or scheduling a wellness check — can go a long way in keeping you and your family healthy.
