How Long Does A Sinus Infection Last? A sinus infection can last anywhere from 10 days to several weeks. The length of a sinus infection usually depends on whether the cause is viral (i.e. a cold or flu) or bacterial (i.e. Streptococcus pneumonia - “strep throat” or Haemophilus influenzae).
Are sinus infections contagious? No. Sinus infections are not contagious. Sinus infections are sometimes the result of contagious viruses, such as the common cold or influenza. In many cases, people are experiencing common symptoms, including a sinus infection, in response to a viral infection (which is contagious). In other cases, sinus infections are the result of airborne bacteria, fungi, and allergens.
What Is A Sinus Infection? A sinus infection is commonly identified by the swelling and inflammation of the sinus lining. Symptoms of a sinus infection may include a stuffy and congested nose, discolored discharges, post-nasal drip (an overproduction of mucus in the back of the throat), anosmia (reduced or no sense of smell or taste), and swelling and tenderness around your eyes.
