But is your infection caused by a virus or bacteria — and does it really matter? Doctors treat viral and bacterial sinus infections differently. fever and headache are not reliable signs of a bacterial infection,” he says. Even your doctor can’t tell if your infection is viral or bacterial based solely on symptoms or an exam.” Instead, your doctor looks at symptom duration to determine the source of your infection. Here is what you need to know about both kinds of infection and how to treat them. How can you tell, based on symptoms, whether your infection is viral or bacterial? A viral sinus infection will usually start to improve after five to seven days. A bacterial sinus infection will often persist for seven to 10 days or longer, and may actually worsen after seven days. Whether your sinus infection turns out to be viral or bacterial, you can help to ease your symptoms early on with supportive care: If your symptoms aren’t improving after one week, it’s important to see your doctor. If your doctor suspects a bacterial infection, you’ll probably need to take an antibiotic to clear up the infection and prevent further complications. Note: Antibiotics won’t help a viral infection, and taking an antibiotic unnecessarily can do more harm than good. You risk possible side effects and increase your chances of developing antibiotic resistance, which can make future infections harder to treat, says Dr. So it’s important to wait and see how long your symptoms last. Culturing it in a laboratory will reveal which type of bacteria is causing the infection so the right antibiotic can be prescribed. The Canadian clinical practice guidelines for acute bacterial rhinosinusitis based the diagnosis of acute bacterial sinusitis on the presence of specific symptoms and their duration; imagining or cultures are not needed in uncomplicated cases. The guidelines for treatment depend on symptom severity and recommend intranasal corticosteroids (INCSs) as monotherapy for mild and moderate cases, although the benefit might be modest. The use of INCSs plus antibiotics is reserved for patients who fail to respond to INCSs after 72 hours and for initial treatment of patients with severe symptoms. The guidelines recommended that antibiotic selection must account for the suspected pathogen, the risk of resistance, comorbid conditions, and local antimicrobial resistance trends. Adjunctive therapies such as nasal saline irrigation are recommended. Failure to respond to treatment, recurrent episodes, and signs of complications should prompt referral to an otolaryngologist. The 2007 guidelines by the American Academy of Otolaryngology--Head and Neck Surgery Foundationand recommended that clinicians (1) either offer watchful waiting (without antibiotics) or prescribe initial antibiotic therapy for adults with uncomplicated acute bacterial rhinosinusitis or (2) prescribe amoxicillin with or without clavulanate as ﬁrst-line therapy for 5-10 days (if the decision is made to treat acute bacterial rhinosinusitis with an antibiotic).
