Viral etiologies of hospitalized acute lower respiratory infection patients in China, 2009-2013.

ABSTRACT:

Background

Acute lower respiratory infections (ALRIs) are an important cause of acute illnesses and mortality worldwide and in China. However, a large-scale study on the prevalence of viral infections across multiple provinces and seasons has not been previously reported from China.
