medica-seed-editor · October 25, 2026, 3:35am

Understanding the term common cold in English helps in distinguishing its symptoms from allergies and the flu, which is essential for determining the appropriate treatment for each condition.

Cold vs Allergies: Key Differences

Colds occur due to infectious viruses transmitted from person to person, while allergies result from an overreaction of the immune system to non-infectious triggers such as dust and pollen.

Main differences in symptoms:

Mucus: It is typically clear in allergy cases, whereas it becomes thicker in a cold and often turns yellow or green due to white blood cells.
Itching: Itchy eyes and nose are strong indicators of allergies and are rare in cases of a cold.
Fever and Aches: Fever and body aches usually indicate a cold, while seasonal allergies never cause a fever.
Duration: Colds last from one to two weeks, but allergies may persist for six weeks or more as long as exposure to the trigger continues.

How to Distinguish a Cold in English from the Flu?

Both are viral respiratory illnesses, but the flu is more severe, and its symptoms appear suddenly and acutely.

Flu: Characterized by high fever (often 38°C or higher), severe fatigue and exhaustion that may last for weeks in older adults, muscle aches, and a dry cough.
Cold: This is milder, often characterized by nasal congestion and runny nose, with symptoms developing gradually.

Head Cold in Children and Infants

A runny nose or congestion is one of the most frequent illnesses in children, and a child may experience more than five episodes in a single winter.

Common symptoms:

Sore throat and burning as an initial sign.
Runny or blocked nose, sneezing, and coughing.
Headache and a slight increase in temperature with a loss of appetite.

Tips to relieve symptoms:

Use saline spray to clear the nose.
Humidify the room with steam.
Use petroleum jelly externally to soothe nasal irritation.
Ensure plenty of rest and fluid intake.

Prevention and Infection

Infection is transmitted through respiratory droplets or by touching contaminated surfaces; viruses can move from the eyes to the nose and then to the throat.

For prevention, it is recommended to:

Wash hands frequently.
Cover the mouth and nose when coughing or sneezing.
Keep children away from smokers and those with a cold.
Avoid sharing towels and eating utensils.
