Shortness of breath is a common symptom in both illnesses, but COVID-19 is more likely to cause severe respiratory issues, sometimes leading to pneumonia.
While both illnesses can result in sneezing and a runny or stuffy nose, the flu often presents with more pronounced nasal symptoms, while COVID-19 tends to cause a dry cough.
An unusual symptom more associated with COVID-19 is the loss of taste or smell, which is not commonly observed in flu cases.
Digestive symptoms like nausea and diarrhea are more prevalent in COVID-19 cases than in flu cases.
Children are generally more susceptible to the flu, and severe pediatric cases are often associated with influenza rather than COVID-19.
While both illnesses can vary in duration, COVID-19 tends to have a more extended recovery period, with some individuals experiencing lingering symptoms for weeks or even months.
Muscle and body aches are typical in both illnesses, but COVID-19 may involve more widespread discomfort and severe body aches compared to the flu.
The flu typically has a sudden onset of symptoms, hitting hard and fast. In contrast, COVID-19 symptoms may develop more gradually over a few days.
The most conclusive way to distinguish between COVID-19 and the flu is through testing. PCR tests can detect the presence of viruses, helping healthcare professionals tailor appropriate treatments.
