Cold vs COVID: 20 Key Differences Everyone Should Know
15. Loss of Appetite and Weight Loss

The common cold usually doesn’t significantly impact appetite, though some may experience a temporary loss of taste due to nasal congestion. However, COVID-19 often leads to a noticeable loss of appetite, even in those who don’t experience nausea or vomiting. Some patients report losing a significant amount of weight during their illness due to prolonged fatigue, nausea, and changes in taste perception.
16. Night Sweats and Chills
One lesser-known but telling symptom of COVID-19 is night sweats—intense sweating that soaks your clothes or bed sheets, even in a cool room. While fever and chills can happen with both a cold and COVID-19, night sweats tend to be more common with COVID-19 and can persist for days, often appearing alongside a fever or extreme fatigue.
