For many, the flu and the common cold are mundane illnesses that don’t warrant much concern. However, these ailments can lead to dangerous complications if left untreated.
According to Dr. Hao-Chun Hu, Head of the Department of Otolaryngology at Fu Jen Catholic University Hospital in Taiwan, the flu and the common cold usually differ in the speed of onset, the extent of debilitation, fever, and muscle aches.
The US Centers for Disease Control and Prevention (CDC) states that the common cold is typically milder than the flu. Compared to the flu, people with a cold are more likely to have a stuffy or runny nose. Additionally, a cold rarely leads to serious complications such as pneumonia or bacterial infections, whereas the flu can.
Differentiating Between the Flu and the Common Cold
– The Flu Usually Onsets Faster
As per Dr. Hu, the flu typically develops more rapidly. Patients may feel unwell after just one night, with symptoms evolving quickly. Initially, one might only experience coughing, but by the next night, other discomforts could emerge. The patient could even feel so exhausted that getting out of bed becomes a challenge.
In contrast, cold symptoms tend to appear gradually. One might feel progressively worse over a few days, with varying levels of discomfort.
– The Flu is Often Accompanied by Severe Systemic Weakness
The doctor also points out that the flu can be accompanied by severe systemic weakness, leaving patients feeling exhausted, feeble, and helpless. It may cause significant disruptions to daily life. While a cold also affects one’s physical well-being, it is usually relatively mild.

The flu and the common cold have some distinct differences.
– The Flu Often Includes High Fever
The flu is often characterized by a high fever, sometimes exceeding 38°C and lasting for several days. In contrast, a cold may also cause a fever, but it is usually milder, and the affected individual may not experience any fever at all.
– Sore Throat is Not a Primary Symptom of the Flu
A sore throat is not considered a primary symptom of the flu, whereas it is a common occurrence with a cold, often causing throat pain and itchiness.
– The Flu Typically Causes Severe Muscle and Joint Aches
One of the hallmark symptoms of the flu is severe muscle and joint pain, which can be debilitating and impact daily life. In contrast, muscle and joint aches caused by a cold are typically much milder, and one may not experience any such symptoms at all.
When to Seek Medical Attention
Whether it’s the flu or a cold, it’s important not to be complacent. If symptoms become severe, it is best to seek medical attention. If you find yourself unable to perform normal functions, are having difficulty breathing, eating, or drinking, or are experiencing cognitive issues, go to the hospital as soon as possible. This is especially important for individuals with chronic illnesses.
