Respiratory Viral Infections

 Viral infections  commonly affect the upper or lower tract. Severity of viral respiratory disease varies widely; severe disease is more likely in older patients and infants. Morbidity may result directly from virus infection or could also be indirect, thanks to exacerbation of underlying cardiopulmonary conditions or bacterial superinfection of the lung, paranasal sinuses, or tympanic cavity . Viral respiratory infections are typically diagnosed clinically supported symptoms and native epidemiology. For patient care, diagnosing the syndrome is typically sufficient; identification of a selected pathogen is never necessary.  Pathogen identification are often important within the rare instances when specific antiviral therapy is contemplated. Antibacterial drugs are ineffective against viral pathogens, and prophylaxis against secondary bacterial infections isn't recommended. Antibiotics should tend only secondary bacterial infections develop. In patients with chronic lung disease, antibiotics could also be given with less restriction. Aspirin shouldn't be utilized in patients who are ≤ 18 years and have respiratory infections  because Reye syndrome may be a risk. Some patients still cough for weeks after resolution of an upper respiratory infection; these symptoms may lessen with use of an inhaled bronchodilator or corticosteroids.
