RESPIRATORY HEALTH
Is It Just a Cold or the Flu?
Flu season in South Africa can affect people of all ages, causing uncomfortable symptoms that interfere with work, school, and daily life. Influenza, commonly known as the ‘flu’, is a contagious viral infection that spreads easily through coughing, sneezing, and close contact with infected individuals.
While many cases improve with rest and home care, some people may develop complications that require medical attention. Understanding the symptoms of the flu, available treatment options, and when to consult a doctor can help you recover faster and avoid serious illness.
At Doctors on Demand South Africa, you can book an online consultation with a qualified doctor from the comfort of your home and receive professional medical advice quickly and conveniently.

What Is the Flu?
The flu is a respiratory infection caused by influenza viruses. It typically affects the nose, throat, and lungs and can range from mild to severe.
Flu viruses spread rapidly, especially during colder months and in crowded environments such as schools, offices, and public transport.
Common Flu Symptoms
Flu symptoms usually appear suddenly and may include:
- Fever or chills
- Sore throat
- Dry cough
- Runny or blocked nose
- Headaches
- Muscle and body aches
- Fatigue and weakness
- Sweating
- Loss of appetite
- Nausea or vomiting (more common in children)
These symptoms may also be confused with the common cold, bacterial upper respiratory infection or allergies.

Some individuals are more vulnerable to severe flu symptoms and complications, including:

If you fall into a high-risk category, it is important to seek medical advice early.
Flu Treatment
It is important to know that flu symptoms are NOT treated with antibiotics. Most people recover with symptom relief, fluids and rest in 1 week. Your doctor may prescribe antibiotics only when a bacterial infection is suspected.
Rest and Hydration
Getting enough rest and drinking plenty of fluids helps your body fight the infection and prevents dehydration.
Over-the-Counter Medication
Pain relievers and fever reducers may help manage symptoms such as headaches, fever, and body aches.
Monitoring Symptoms
Seek urgent medical attention if you experience:
- Difficulty breathing
- Chest pain
- Persistent high fever
- Severe dehydration
- Confusion
- Blue lips or blue face
How to Prevent the Flu
You can reduce your risk of getting the flu by:
- Washing your hands regularly with soap
- Covering coughs and sneezes
- Avoiding close contact with sick individuals
- Staying home when unwell
- Getting an annual flu vaccine
When Should You See a Doctor?
At any point when you suspect you have the flu and it impairs your function at work or home. It is important to stay home from work to rest, and this may lead to you needing to see a doctor for a medical certificate. It is also important to note that if you are working around high-risk groups (newborns, elderly) that you rather stay home or wear a mask if needed.
An online consultation allows you to receive medical guidance without visiting a clinic or exposing others to infection.
