Cold, Flu, or COVID? Spot the Difference Fast

Summary
- Bronchitis, caused by viruses or bacteria, inflames airways.
- Flu season peaks December-February; COVID-19 symptoms can linger.
- New COVID variant XFG (Stratus) shares symptoms with other strains.

As the winter months arrive, identifying the cause of your illness—be it a common cold, the flu, or COVID-19—becomes increasingly important. Bronchitis, characterized by inflamed bronchial tubes filled with mucus, is typically caused by viruses or bacteria, though the condition itself isn't contagious. Acute bronchitis is temporary, while chronic bronchitis is long-term.
The flu, a common respiratory illness caused by the influenza virus, typically sees its peak season between December and February. Symptoms often include fever, sore throat, fatigue, and body aches. Meanwhile, COVID-19, caused by a coronavirus, shares some symptoms like fever and cough, but can also lead to a loss of taste or smell and potentially long-lasting effects.
New variants of COVID-19 continue to emerge, with XFG, also known as the Stratus variant, being the most recent. Its symptoms, including congestion, cough, and fever, are similar to other strains. Understanding these distinctions, alongside preventative measures like vaccinations, helps in managing and preventing the spread of these widespread winter illnesses.
