A routine chest X-ray is not always necessary for people who have symptoms of a lower respiratory tract infection. [4] Influenza affects both the upper and lower respiratory tracts. [citation needed] Antibiotics are the first line treatment for pneumonia; however, they are neither effective nor indicated for parasitic or viral infections. Acute ...
An upper respiratory tract infection (URTI) is an illness caused by an acute infection, which involves the upper respiratory tract, including the nose, sinuses, pharynx, larynx or trachea. [ 3 ] [ 4 ] This commonly includes nasal obstruction, sore throat, tonsillitis , pharyngitis , laryngitis , sinusitis , otitis media , and the common cold .
The lower respiratory tract consists of the trachea (windpipe), bronchial tubes, bronchioles, and the lungs. [6] Lower respiratory tract infections (LRIs) are generally more severe than upper respiratory infections. LRIs are the leading cause of death among all infectious diseases. [7] The two most common LRIs are bronchitis and pneumonia. [8]
Pneumonia frequently starts as an upper respiratory tract infection that moves into the lower respiratory tract. [55] It is a type of pneumonitis (lung inflammation). [ 56 ] The normal flora of the upper airway give protection by competing with pathogens for nutrients.
Acute pain is something more than 80 million Americans fill prescriptions to treat each year, according to Vertex. As opposed to chronic pain, which can last well after an injury or illness has ...
Details of upper respiratory tract. The upper respiratory tract can refer to the parts of the respiratory system lying above the vocal folds, or above the cricoid cartilage. [4] [5] The larynx is sometimes included in both the upper and lower airways. [6] The larynx is also called the voice box and has the associated cartilage that produces sound.
One of the most common causes is Staphylococcus aureus and often follows a recent viral upper respiratory infection. Bacterial tracheitis is a rare complication of influenza infection. [ 4 ] It is the most serious in young children, possibly because of the relatively small size of the trachea that gets easily blocked by swelling.
The respiratory syncytial virus , on the other hand, is contracted by direct contact and airborne droplets. It then replicates in the nose and throat before spreading to the lower respiratory tract. [48] RSV does cause epithelium damage. [48] Human parainfluenza virus typically results in inflammation of the nose, throat, and bronchi. [49]
