How to distinguish between the flu and a cold?
The flu starts suddenly, with a high fever and severe fatigue. A cold comes on gradually and is milder.
During the fall and winter months, both flu and common cold cases increase. Since these conditions share similar symptoms, they are often confused with one another. However, knowing the differences between them is essential for accurate diagnosis and effective treatment.
What is the flu?
Flu (influenza) is an acute infectious respiratory illness of viral origin, characterized by sudden onset, high fever, muscle aches, and general weakness. Symptoms usually appear within 1–2 days and can last for a week or longer.
The main symptoms of the flu are:
- Sudden high fever (38°C and above)
- Severe headache, muscle, and throat pain
- Dry cough and general weakness
- Vomiting or diarrhea (especially in children)
What is a cold?
A cold is a milder virus upper respiratory infection, often accompanied by a runny nose, sore throat, and sneezing. It usually starts within a few days and resolves in 5–7 days.
The main symptoms of a cold:
- Runny and stuffy nose
- Itchy and mildly sore throat
- Sneezing
- Low or normal body temperature
- Mild fatigue
How to Prevent Flu and a Cold?
- Frequent hand washing – prevents the spread of viruses.
- Strengthening immunity – balanced nutrition, vitamins and healthy sleep are important.
- Avoid crowded and enclosed spaces – this reduces the risk of infection.
- Fever and symptom control – early intervention prevents complications.
- Flu vaccination – especially recommended for people at risk.
Although the flu and the cold may appear similar, their symptoms and progression are different. A proper diagnosis and timely measures can help protect both yourself and those around you.
