COVID-19: Symptoms, Treatment, Testing and When to Seek Medical Advice
By Doctors On Demand, South Africa
What Is COVID-19?
COVID-19 is a respiratory illness caused by the SARS-CoV-2 virus. Although the global pandemic phase has passed, COVID-19 continues to circulate worldwide and remains a significant cause of respiratory infections.
Most people experience mild to moderate symptoms and recover without requiring hospital treatment. However, some individuals are at increased risk of severe illness and may need medical care. Older adults, pregnant women, people with weakened immune systems and those with chronic health conditions remain at higher risk of complications.
How Does COVID-19 Spread?
COVID-19 spreads primarily through respiratory droplets and airborne particles released when an infected person talks, coughs, sneezes or breathes. Transmission is more likely in crowded indoor environments with poor ventilation.
The virus can spread even before symptoms develop, therefore some infected individuals may have few or no symptoms while still transmitting the infection.
Common COVID-19 Symptoms
COVID-19 symptoms can vary from person to person and may range from mild to severe.
Common symptoms include:
- Fever or chills
- Sore throat
- Cough
- Fatigue
- Runny or blocked nose
- Headache
- Muscle aches
- Loss of, or change in taste or smell
- Nausea or vomiting
- Diarrhoea
- Shortness of breath
Symptoms typically appear within a few days of exposure to the virus, although timing can vary. (World Health Organization)
COVID-19 vs Cold and Flu
Many COVID-19 symptoms overlap with the common cold and influenza, making it difficult to tell the difference without testing.
Common Cold
- Usually mild
- Runny nose and sneezing are common
- Fever is uncommon
Influenza (Flu)
- Often a sudden onset
- Fever
- Body aches and fatigue
COVID-19
- May cause respiratory, gastrointestinal or flu-like symptoms
- Can include loss of taste or smell
- Symptoms vary significantly between individuals
If you are unsure about your symptoms, a healthcare professional can help determine whether testing or treatment is appropriate.
When Should You Get Tested?
Testing may be appropriate if:
- You develop symptoms consistent with COVID-19
- You have been exposed to someone with COVID-19
- You are at high risk of severe illness
- You need confirmation for work, travel or medical reasons
A healthcare provider can advise on the most suitable testing options based on your circumstances.
Treatment for COVID-19
Most people with mild COVID-19 can recover at home with supportive care.
Self-Care Measures
- Rest and recovery
- Adequate hydration
- Fever and pain relief medications as needed
- Monitoring symptoms closely
Prescription Treatments
Some individuals experiencing more severe disease may qualify for other treatments in addition to simple supportive management. Early medical assessment is important because certain treatments are most effective when started within a specified window. (World Health Organization)
Warning Signs That Need Urgent Medical Attention
Seek immediate medical care if you experience:
- Difficulty breathing
- Persistent chest pain or pressure
- Confusion
- Blue or pale peripheries
- Inability to stay awake
- Severe worsening of symptoms
These may indicate a serious illness requiring urgent evaluation. (World Health Organization)
What Is Long COVID?
Some people continue to experience symptoms weeks or months after the initial infection. This condition is often referred to as long COVID or Post COVID-19 condition.
Symptoms may include:
- Persistent fatigue
- Shortness of breath
- Brain fog or difficulty concentrating
- Sleep disturbances
- Muscle or joint pain
- Ongoing cough
If symptoms continue for more than 2 months after initial diagnosis, medical assessment can help identify appropriate management strategies. (World Health Organization)

Individuals at increased risk include:
- Adults over 60 years of age
- People with diabetes
- Individuals with heart disease
- People with chronic lung conditions
- Those with obesity
- People with weakened immune systems

These individuals should seek medical advice promptly if COVID-19 symptoms develop. (World Health Organization)
