As cases of cough, cold, and fever rise, distinguishing between seasonal flu, common viral fever, and COVID-19 becomes challenging due to overlapping symptoms. All three can present with fever, fatigue, body aches, and cough, potentially delaying testing, treatment, and isolation. Doctors emphasize that while flu often starts suddenly with intense symptoms, viral fever is a broad term. Misinterpreting early signs can be risky, especially for vulnerable populations. Understanding the distinct patterns and knowing when to seek testing is crucial for effective recovery and prevention.
