Differences between the common cold and the flu
The common cold is an infection of the respiratory tract (nose, throat and lungs) caused by several virus strains. Often mistaken for the flu, it differs in terms of both its origin and its symptoms, which are rather benign.
Many of us have trouble differentiating a cold from the flu. This is understandable since both infections affect the upper respiratory tract in similar ways. Yet, they’re very different.
The best way to know if you have a cold or the flu is to pay close attention to your symptoms.

Causes
The common cold normally hits from September to February, peaking during back-to-school time, the middle of winter and the beginning of spring.
Colds can be caused by one of 200 types of virus, the most common being the rhinovirus.
Much like the flu, the common cold is also transmitted easily from one person to another through tiny airborne droplets. When a person infected with a cold coughs or sneezes, he or she projects into the air millions of virus-laden particles, ready to contaminate others.
Treatment
There is no cure for the common cold. However, the following tips can help to keep symptoms from getting worse.
- Stay home and rest. This will help you feel better and make sure you don’t pass it on.
- Keep warm and drink plenty of fluids (warm liquids reduce congestion).
- Gargle with salted water to ease your sore throat.
- Keep the ambient air moist to relieve coughing (use a humidifier if needed).
Medications
Certain over-the-counter medications can help to reduce symptoms. These include:
- Nasal decongestants in a tablet, spray or drops
- Cough suppressants for dry coughs
- Expectorants to alleviate congestion
- Antihistamines to reduce nasal discharge
- Analgesics for pain relief.
To learn more about these medications, ask your pharmacist. He can help you choose the medication best suited to your symptoms.
Ironically, the best protection against the common cold is to catch it. In fact, once you are infected with a given strain, you will be immunized against it for several months.
