Key Differences
The Common Cold
Usually mild and resolves within a few days.
Symptoms include a runny nose, mild cough, and sore throat.
Rarely causes a fever.
Influenza (Flu)
Symptoms come on suddenly and are more severe than a cold.
High fever, intense fatigue, and body aches are hallmarks.
Can lead to complications like pneumonia in severe cases.
COVID-19
Symptoms range from mild to severe and can appear 2-14 days after exposure.
Unique symptoms include a sudden loss of taste or smell.
Can cause serious complications such as respiratory distress.
When to Seek Urgent Care
While mild symptoms of these illnesses can often be managed at home, there are situations where seeking urgent care is essential:
High or persistent fever (above 103°F for adults or 102°F for children).
Difficulty breathing or shortness of breath.
Chest pain or pressure.
Severe dehydration (dry mouth, minimal urination, dizziness).
Worsening symptoms despite home care.
