Cold, Flu, or COVID? Doctor's Guide to Symptoms

As the colder months arrive, identifying the specific culprit behind coughs and sneezes becomes paramount. While colds typically manifest gradually with nasal and throat symptoms, flu strikes suddenly, leaving individuals feeling wiped out with fever and aches. COVID-19 further complicates diagnosis, sharing many flu symptoms but often featuring a loss of smell or taste, a sharp sore throat, or gastrointestinal issues.

Factors contributing to the current surge in illnesses include people congregating in warm, indoor spaces, which provide fertile ground for viruses. Schools and universities, with their close-quarters mixing, become hotspots for germ transmission, especially after holidays. NHS leaders have noted an earlier and more severe flu season this year, with a circulating strain of influenza A(H3N2) being particularly potent, though current vaccines remain effective.
