Allergy or Flu? How to Tell the Difference This Season
Spring in South Africa brings longer days, blossoming trees, and a welcome change in weather. But it also marks the start of two health challenges that often overlap — seasonal allergies and flu season.
Spring in South Africa brings longer days, blossoming trees, and a welcome change in weather. But it also marks the start of two health challenges that often overlap — seasonal allergies and flu season. With symptoms that can appear similar at first, it’s easy to mistake one for the other. Knowing the difference is important so you can get the right treatment quickly and start feeling better.
Allergy vs Flu: Spot the Difference
Allergies and flu may share certain signs, like a runny nose or fatigue, but their causes and treatments are very different. Allergies are triggered by your immune system reacting to harmless substances like pollen, while the flu is caused by a viral infection.
Here’s a quick comparison to help you tell them apart:
| Symptom | Allergies | Flu |
|---|---|---|
| Onset | Gradual, often seasonal or environmental | Sudden, can feel unwell within hours |
| Fever | Rare | Common (often high) |
| Runny/Stuffy Nose | Very common | Sometimes |
| Sneezing | Frequent | Less common |
| Cough | Sometimes (dry) | Common, often severe |
| Body Aches | Unusual | Very common |
| Fatigue | Mild | Moderate to severe |
| Itchy Eyes/Throat | Very common | Rare |
When to See a Doctor
While mild allergies or flu can often be managed at home, there are times when you should seek medical attention:
High fever that doesn’t improve with medication
Shortness of breath or wheezing
Severe or persistent cough
Symptoms that last more than 10 days without relief
If you have an existing condition (like asthma or diabetes) that makes complications more likely
