These days, coughs and colds are everywhere. It seems to be very difficult for the body. Now you may be wondering, 'Do I have a simple cold, or is it the flu that everyone is afraid of?' It is very important to know the difference between the two. Because flu is a condition that can sometimes be serious. So let's talk about this clearly today.
What is the difference between the flu and the common cold?
Simply put, both are respiratory infections caused by viruses . But there are two types of viruses that cause them. The common cold is a mild condition that usually resolves in a few days. It mainly involves a runny nose , sneezing , and a slight sore throat.
But the flu , or what we medically call influenza , is a bit more serious. Flu symptoms start suddenly, almost suddenly. The physical discomfort is also much greater.
Think of a cold as a light drizzle, while the flu is like a storm that hits all at once. It can make your body feel just as tired and sore.
These are the main symptoms of the flu.
If you suspect you have the flu, watch out for the symptoms below. Not everyone will have all of them, but if you have several of them together, you are more likely to have the flu.
| Symptom | How does that feel? |
|---|---|
| Fever | A sudden onset of a high fever, usually 38 degrees Celsius (100.4 Fahrenheit) or higher. |
| Chills | Feeling extremely cold and shivering despite having a fever. |
| Muscle Aches | Severe pain in the joints and muscles. It feels like someone is hitting you. |
| Dry, hacking cough | A painful, dry cough that comes from deep in the chest, without mucus. |
| Fatigue and weakness | Feeling extremely tired and lifeless, unable to do anything. This can last for weeks. |
| Headache | Severe headache. |
| Sore throat | Sore throat, pain when swallowing. |
| Headache/nasal congestion | Some people may experience nasal congestion, sneezing, and lightheadedness. |
You definitely need to see a doctor!
Most of the time, the flu will go away with plenty of rest, fluids, and fever medicine. But sometimes it can be serious. It is especially important to seek medical advice immediately if you have any of the following: These may be warning signs.
| Situation | Why is it risky? |
|---|---|
| If you belong to risk categories: | |
| If your immune system is weak (e.g. due to conditions such as diabetes, cancer, AIDS). | The risk of developing severe complications from the flu, such as pneumonia, is higher because the body's ability to fight disease is reduced. |
| If you already have a serious illness (heart disease, lung disease, kidney disease, severe asthma). | Flu infection can cause your existing medical condition to worsen out of control. |
| If there are warning symptoms: | |
| If you feel difficulty breathing or chest tightness. | This may be a sign that the infection has spread to the lungs (pneumonia). |
| If you have a severe headache accompanied by a stiff neck . | This could be a sign of a very serious condition, such as brain fever, which requires immediate treatment. |
| If the fever persists for more than 3-4 days , if it gets worse even when resting, or if there is chest pain. | These are also strong signs that a bacterial infection such as pneumonia has developed. |
| If the nasal discharge is yellow or green and lasts for more than 10 days . | This is most likely a sinus infection caused by bacteria, which may require antibiotics. |
What do you do in an emergency?
If you experience any of the above serious symptoms, especially severe shortness of breath, loss of consciousness, blue lips, or severe chest pain , do not stay at home. Go to the nearest hospital Emergency Department (ETU) immediately. Time is of the essence in such a situation.
