0 the parts of the body that air passes through during the act of breathing, consisting of the mouth, nose, throat, and lungs:
upper respiratory tract infections such as the common cold
lower respiratory tract infections such as pneumonia
Currently, a more efficient method of delivery to the respiratory tract is necessary.
It often follows an upper respiratory tract infection, particularly with streptococci.
There is very little research to inform practice in the use of antipyretics in upper respiratory tract infection.
Common symptoms are sudden respiratory distress-particularly in cold air, during respiratory tract infections, and during stress-"wheezy chest," and nocturnal coughing.
Treatment recommendations for respiratory tract infections associated with aging.
Except for acute otitis media episodes, other upper respiratory tract infections were not included in our primary outcome measure.
In most cases, we found that the diagnosis of asthma preceded the diagnosis of pneumonia, suggesting that asthma predisposes children to lower respiratory tract infection.
At 14 months of age, the child suffered from an upper respiratory tract infection with fever, rhinitis and cough.
