Upper respiratory tract infection Wikipedia. Upper respiratory tract infections URI or URTI are illnesses caused by an acute infection which involves the upper respiratory tract including the nose, sinuses, pharynx or larynx. This commonly includes nasal obstruction, sore throat, tonsillitis, pharyngitis, laryngitis, sinusitis, otitis media, and the common cold. Russian For Everybody Textbook. Most infections are viral in nature and in other instances the cause is bacterial. Upper respiratory tract infections can also be fungal or helminth in origin, but these are far less common.

As of 2. 01. 4, upper respiratory infections caused about 3,0. ClassificationeditA URI may be classified by the area inflamed. Rhinitis affects the nasal mucosa, while rhinosinusitis or sinusitis affects the nose and paranasal sinuses, including frontal, ethmoid, maxillary, and sphenoid sunuses. Nasopharyngitis rhinopharyngitis or the common cold affects the nares, pharynx, hypopharynx, uvula, and tonsils generally.

Without involving the nose, pharyngitis inflames the pharynx, hypopharynx, uvula, and tonsils. Similarly, epiglottitis supraglottitis inflames the superior portion of the larynx and supraglottic area laryngitis is in the larynx laryngotracheitis is in the larynx, trachea, and subglottic area and tracheitis is in the trachea and subglottic area. Signs and symptomsedit. Time line for cold symptoms. In uncomplicated colds, cough and nasal discharge may persist for 1. Acute upper respiratory tract infections include rhinitis, pharyngitistonsillitis and laryngitis often referred to as a common cold, and their complications sinusitis, ear infection and sometimes bronchitis though bronchi are generally classified as part of the lower respiratory tract. Symptoms of URTIs commonly include cough, sore throat, runny nose, nasal congestion, headache, low grade fever, facial pressure and sneezing. Symptoms of rhinovirus in children usually begin 13 days after exposure. The illness usually lasts 71. Color or consistency changes in mucous discharge to yellow, thick, or green are the natural course of viral upper respiratory tract infection and not an indication for antibiotics. Group A beta hemolytic streptococcal pharyngitistonsillitis strep throat typically presents with a sudden onset of sore throat, pain with swallowing and fever. The common cold and most upper respiratory infections are caused by infection with germs viral infections. They usually get better in a week or two. Research Vitamin D.

INTERIM GUIDANCE DOCUMENT Clinical management of severe acute respiratory infections when novel coronavirus is suspected What to do and what not to do. Strep throat does not usually cause runny nose, voice changes, or cough. Pain and pressure of the ear caused by a middle ear infection otitis media and the reddening of the eye caused by viral conjunctivitis are often associated with upper respiratory infections. In terms of pathophysiology, rhino virus infection resembles the immune response. The viruses do not cause damage to the cells of the upper respiratory tract but rather cause changes in the tight junctions of epithelial cells. This allows the virus to gain access to tissues under the epithelial cells and initiate the innate and adaptive immune responses. Up to 1. 5 of acute pharyngitis cases may be caused by bacteria, most commonly Streptococcus pyogenes, a group A streptococcus in streptococcal pharyngitis strep throat. Other bacterial causes are Streptococcus pneumoniae, Haemophilus influenzae, Corynebacterium diphtheriae, Bordetella pertussis, and Bacillus anthraciscitation needed. Sexually transmitted infections have emerged as causes of oral and pharyngeal infections. DiagnosiseditURI, seasonal allergies, influenza symptom comparison. Symptoms. Allergy. URIInfluenza.

Vaccination against influenza viruses, adenoviruses, measles, rubella, Streptococcus pneumoniae, Haemophilus influenzae, diphtheria, Bacillus anthracis, and Bordetella pertussis may prevent them from infecting the URT or reduce the severity of the infection. Treatmentedit. Upper respiratory infections deaths per million persons in 2. The Centers for Disease Control describe protocol for treating sinusitis while at the same time discouraging overuse of antibiotics Target likely organisms with first line drugs Amoxicillin, AmoxicillinClavulanate. Use shortest effective course Should see improvement in 23 days. Continue treatment for 7 days after symptoms improve or resolve usually a 1. Consider imaging studies in recurrent or unclear cases some sinus involvement is frequent early in the course of uncomplicated viral URI4Treatment comprises symptomatic support usually via analgesics for headache, sore throat and muscle aches. Moderate exercise in sedentary subjects with naturally acquired URTI probably does not alter the overall severity and duration of the illness. No randomized trials have been conducted to ascertain benefits of increasing fluid intake. AntibioticseditPrescribing antibiotics for laryngitis is not suggested practice. The antibiotics penicillin V and erythromycin are not effective for treating acute laryngitis. Erythromycin may improve voice disturbances after one week and cough after two weeks, however any modest subjective benefit is not greater than the adverse effects, cost, and the risk of bacteria developing resistance to the antibiotics. Health authorities have been strongly encouraging physicians to decrease the prescribing of antibiotics to treat common upper respiratory tract infections because antibiotic usage does not significantly reduce recovery time for these viral illnesses. Decreased antibiotic usage could also have prevented drug resistant bacteria. Some have advocated a delayed antibiotic approach to treating URIs which seeks to reduce the consumption of antibiotics while attempting to maintain patient satisfaction. Most studies show no difference in improvement of symptoms between those treated with antibiotics right away and those with delayed prescriptions. Most studies also show no difference in patient satisfaction, patient complications, symptoms between delayed and no antibiotics. A strategy of no antibiotics results in even less antibiotic use than a strategy of delayed antibiotics. DecongestantseditDisability adjusted life year for upper respiratory infections per 1. According to a Cochrane review, single oral dose of nasal decongestant in the common cold is modestly effective for the short term relief of congestion in adults however, there is insufficient data on the use of decongestants in children. Therefore, decongestants are not recommended for use in children under 1. Oral decongestants are also contraindicated in patients with hypertension, coronary artery disease, and history of bleeding strokes.
