A general practitioner has shared a straightforward symptom test to help individuals determine whether they are suffering from Covid or influenza. While these two illnesses share several overlapping signs, there are distinct characteristics that can differentiate them, which is crucial for ensuring appropriate medical care and treatment.
Understanding the Key Differences
During the winter months, distinguishing between Covid and flu can be particularly challenging due to their similar presentations. However, identifying the correct condition is vital to manage symptoms effectively and prevent complications. GP and medical director at Midland Health, Doctor Rupa Parmar, has provided expert insights into how to tell these illnesses apart.
Symptom Onset: Sudden vs Gradual
One of the primary ways to differentiate between Covid and flu is the speed at which symptoms appear. According to Dr Parmar, flu symptoms typically emerge "suddenly," often within a few hours, whereas Covid symptoms may start mildly and gradually increase in severity. This distinction is supported by the NHS website, which notes that flu symptoms "come on very quickly" and can include a sudden high temperature. The UK Health Security Agency also highlights that flu signs develop rapidly, with extreme tiredness being a common feature.
Shortness of Breath: A Covid Indicator
Another telltale sign that points more towards Covid than flu is experiencing shortness of breath. Dr Parmar explains that this symptom is rare in both the common cold and flu, but it is more common with Covid due to inflammation affecting the lungs. The NHS lists breathlessness as an indicator of Covid rather than flu or a cold, associating it more with respiratory conditions like Covid or respiratory syncytial virus. It is important to note, however, that if flu worsens and leads to complications such as pneumonia, respiratory problems may also occur.
Cough Characteristics
The type of cough can also help differentiate between these illnesses. Dr Parmar states that while coughs are common in all three viruses—cold, flu, and Covid—they have distinct differences. With a cold, the cough tends to be mild; with flu, it is typically dry; and with Covid, the cough is often dry and continuous. Many people with Covid may cough for more than an hour or experience three or more coughing episodes within a single day.
Loss of Smell or Taste: A Unique Covid Symptom
A loss of taste or smell is a symptom somewhat unique to Covid, according to Dr Parmar. If you are experiencing either a change in taste or a complete loss of these senses, it is most likely that you have contracted the coronavirus. Understanding which virus you have depends on the combination of symptoms and their severity. For instance, a mild cough and sore throat are unlikely to be more than a cold, a fever and severe fatigue suggest the flu, while a loss of smell or taste and a continuous cough point to Covid.
What to Do If You Have Symptoms
While there are no longer any self-isolation regulations in place, the NHS advises that individuals should aim to stay at home and minimise contact with others if they or their children exhibit symptoms and either have a high temperature or feel too unwell to attend work, school, childcare, or carry out regular activities. The health service states that you can return to your normal activities when you feel better or do not have a high temperature.
Dr Parmar emphasises that if you are still unsure about your symptoms, it is always best to consult your doctor. After all, when it comes to health, it is better to be safe than sorry. By paying attention to these key differences—such as symptom onset, presence of shortness of breath, cough type, and loss of taste or smell—you can better identify whether you have Covid or flu and seek appropriate care accordingly.
