Upper Respiratory Tract Infections (URI) is a nonspecific term used to describe acute infections involving the nose, paranasal sinuses, larynx, bronchi and trachea. Upper Respiratory Tract Infections is largely caused by viruses. Some of the common symptoms of Upper Respiratory Tract Infections include fatigue, fever, headache, wheezing and pain during swallowing.
HOW IS UPPER RESPIRATORY TRACT INFECTIONS DIAGNOSED?
Because viruses cause most URIs, the diagnostic role of laboratory investigations and radiologic studies is limited. Viral culture, rapid antigen detection, or polymerase chain reaction (PCR) assay of influenza virus on a nasopharyngeal swab is indicated in patients for whom specific antiviral therapy is recommended. Plain radiography has been largely replaced by computed tomography (CT) in the evaluation of sinusitis, particularly in preparation for corrective surgery.
HOW IS UPPER RESPIRATORY TRACT INFECTIONS TREATED?
People with upper respiratory infections typically diagnose themselves and treat their symptoms at home without requiring doctor's visit or prescription medications. Rest is an important step in treating upper respiratory infections. Usual activities, such as, working and light exercising may be continued as much as tolerated. Increased intake of oral fluids is also generally advised to keep up with the fluid loss from runny nose, fevers, and poor appetite associated with upper respiratory infections.

In many cases, respiratory disorders or infection start off mild but due to lack of proper care turn more serious, which leads to acute complications in the system.
