Winter Viral Infections Linked to Prolonged Symptoms, Including Loss of Smell and Taste

Loss of smell and taste, once strongly linked to COVID-19, is now being reported more frequently following common viral infections and seasonal colds. Clinicians note this winter's respiratory illnesses are more intense and prolonged, with symptoms like persistent cough, sore throat, and extreme fatigue lasting longer than usual. Doctors attribute the surge to weather fluctuations, poor air quality, reduced sunlight, and indoor crowding, which facilitate virus spread and weaken immunity. While fever, cough, and congestion are common, the severity of fatigue and the re-emergence of smell/taste loss are notable.
