Apart from the fact that they are caused by viruses, both flu and COVID-19 have certain overlapping symptoms which can make it difficult for a person at this point to differentiate between the symptoms and illness they may have.
Both the illnesses can cause a fever, muscle pain, cough, cold, congestion, headache and fatigue. However, there could be some symptoms which could be different, and act as clues to differentiating between the two illnesses.
-A stuffy nose is less likely to occur with COVID-19
-Loss of smell and taste is more of a typical COVID-19 symptom
-Other symptoms, such as skin rashes, runny eyes, and brain fog are more commonly associated with newer variants of COVID-19.
