You woke up at the morning, and found yourself having running nose, coughing and have that feverish feeling, how would you know if you are having just merely a common cold, or something more serious, a flu?
We are also under the Vaccination Subsidy Scheme (VSS) 2023/24, providing subsidised seasonal influenza vaccination to eligible Hong Kong residents.
Are common cold and flu the same?
Firstly, they are both contagious respiratory illnesses, however, they caused by different virus. Flu is caused by influenza viruses only. Common cold can be caused by different types of viruses, including rhinoviruses, parainfluenza and seasonal coronavirus; before jumping up, seasonal coronavirus is not the same as the virus that causes COVID-19.
Is common cold or flu more worse?
Generally speaking, flu is worse than the common cold, and the symptoms are much intense and can happen suddenly. However, people suffering from cold are more likely to have a runny nose and flu generally would have a higher chance to result in serious health problems such as pneumonia, bacterial infection, or even seeing yourself being hospitalised.
Symptoms of common cold
You will start with a sore throat, this usually goes away after a day or two. Then follows the runny nose, and congestion along with a cough by around the fourth and fifth days. Usually fever is uncommon in adults. However, for children are more likely to catch a fever.
Nose symptoms usually comes with watery and clear secretion at the first few days and later become thicker and darker.
Symptoms of flu
As mentioned earlier, Flu symptoms are much severe than common cold and Flu happens quickly. You will develop a sore throat, cough, nose congestion, fever and headache. Usually you will also experience muscle aches and soreness.
Your symptoms will improve over two to five days. However, for young and elderly or people with heart and lung problem might develop into pneumonia. If you experience shortness of breath, or your fever comes and go, please go consult your doctor immediately.

Preventing Flu and Cold
As viruses enter the body through the mucous membranes of the nose, eyes, or mouth. It is vital to keep a good hand hygiene, or else you are prone to be infected each time when you touch them with your hands.
