Many people search “sinus or COVID” when they feel sick with symptoms like a blocked nose, headache, or pressure in the face. These symptoms can feel very similar, so it can be hard to know what is causing the illness.
A sinus infection happens when the spaces inside the nose become swollen or filled with mucus. This can cause pressure in the face, a stuffy nose, and thick mucus. Sinus infections are common during colds or allergies.
COVID-19, on the other hand, is a viral illness caused by the coronavirus. It can affect the nose, throat, lungs, and the whole body. COVID can cause symptoms like fever, cough, tiredness, and loss of taste or smell.
Because both illnesses can affect the nose and head, people often feel confused about which one they might have. Knowing the difference can help people decide when to rest at home or when to see a doctor.
In this guide, we explain sinus or COVID in simple words. You will learn the symptoms, the differences, and how to tell them apart.
