Influenza is a viral respiratory infection causing fever, coryza, cough, headache, and malaise. Mortality is possible during epidemics, particularly among high-risk patients (eg, those who are institutionalized, at the extremes of age, have cardiopulmonary insufficiency, or are in late pregnancy). Diagnosis is usually clinical and depends on local epidemiologic patterns. High-risk patients, their caregivers and household contacts, health care practitioners, and all children aged 6 to 24 mo should receive annual influenza vaccination. Antiviral treatments include the neuraminidase inhibitors zanamivir and oseltamivir, which are effective for both influenza A and B, and amantadine and rimantadine, which are effective only against influenza A.
Please see the web pages for more details on Influenza.
