What is Upper Respiratory Tract Infection?
Upper respiratory tract infections can be defined as self-limited irritation and swelling of the upper airways with associated cough and no signs of pneumonia, in a patient with no other condition that would account for their symptoms, or with no history of chronic obstructive pulmonary disease, emphysema, or chronic bronchitis.
These infections involve only the nose, sinuses, pharynx, larynx, and large airways. It is very difficult to define most of the forms of upper respiratory tract infections as it is caused by a variety of bacteria and viruses and presents as acute bronchitis, common cold, influenza and respiratory distress syndromes.
URIs are one of the most common diagnoses in the outpatient setting. Fall months see a peak in incidence of common cold caused by the rhinovirus.
The most common virus is rhinovirus. Other viruses include the influenza virus, adenovirus, enterovirus, and respiratory syncytial virus. Bacteria which may be responsible for sudden onset of pharyngitis is S. pyogenes.
Following risk factors may also be implicated:
- Close contact with children
- Underlying medical condition
- Immunocompromised host
Sign and symptoms
The organism is usually acquired by inhalation of infected droplets. The most common URTIs are rhinitis, pharyngitis, tonsillitis and laryngitis. The most common symptoms include-
- Sore throat
- Runny nose with sneezing
- Nasal congestion
- Low-grade fever with malaise and myalgia
The symptoms appear after one to three days of the exposure and lasts 7-10 days.
