Respiratory tract infection

Respiratory tract infections are infectious diseases involving the respiratory tract including the sinuses, throat, airways and lungs. Respiratory tract infections are usually classified as upper respiratory tract infection or lower respiratory tract infection. Upper respiratory tract infections affect the parts of the respiratory tract including the nose, sinuses, and throat, while lower respiratory tract infections affect the airways and lungs.

 

Common types of upper respiratory tract infection include common cold, sinusitis, tonsillitis, and laryngitis. Common types of lower respiratory tract infection include bronchitis, bronchiolitis, chest infection, and pneumonia. Lower respiratory tract infections are generally more serious than upper respiratory tract infections.

 

Respiratory tract infections are caused by microorganisms, known as bacteria or viruses. Antibiotics are only used to treat bacterial infections. Antibiotics are not effective in treating infections caused by viruses.

呼吸道感染

呼吸道感染是指呼吸道包括鼻竇、咽喉、氣道或肺部的任何部位受到感染引起的疾病。呼吸道感染通常分為上呼吸道感染或下呼吸道感染。上呼吸道感染影響呼吸道的部位包括鼻腔、鼻竇和咽喉,下呼吸道感染影響的部位包括呼吸道和肺部。

 

上呼吸道感染的常見類型包括普通感冒、鼻竇炎、扁桃體炎和喉炎。下呼吸道感染的常見類型包括支氣管炎、細支氣管炎、胸部感染和肺炎。下呼吸道感染通常較上呼吸道感染更嚴重。

 

呼吸道感染是由包括細菌或病毒的微生物引起的。抗生素僅適用於治療細菌感染。抗生素對治療病毒引起的感染無效。
