Difference between a cold and the flu

Many people struggle with coughs, sniffles or fever during this time. But not every cold is the flu – and vice versa. Understanding the differences allows you to take more targeted action and protect yourself better.

While many people talk about ‘the flu’ when they feel ill, in most cases it is a cold – a so-called flu-like infection. Both illnesses are caused by viruses and affect the respiratory tract, but they differ significantly in their course, severity and symptoms.

A cold is caused by rhinoviruses and develops gradually, often starting with a scratchy throat or a slight runny nose, and in most cases is milder than the flu. Sore throat, cough, headache and a runny or blocked nose are among the most common symptoms.

Flu (influenza viruses) usually starts suddenly, often within a few hours, and is accompanied by high fever, severe malaise, chills, severe headache and aching limbs. The condition typically lasts one to two weeks and often results in significant fatigue, which may continue even after the symptoms have improved.

Good hygiene measures such as frequent hand washing, avoiding close contact with sick people or crowds, regularly cleaning surfaces and boosting the immune system help to prevent flu and colds.

You can also have a flu jab if you wish.
