CONCLUSIONS: HPIV infection led to a wide spectrum of symptoms, and similar clinical manifestations were found in the patients with four different types of HPIVs. The study suggested pathogenic activity of HPIV in gastrointestinal illness. The HPIV-1, HPIV-2 and HPIV-3 are second only to respiratory syncytial virus (RSV) as a cause of hospitalizations (2%-17%) for acute respiratory infection among children aged younger than 5 years in the United States [1, [8] [9] [10] . The aims of this study were to explore the epidemiologic features and clinical manifestations of HPIVs and other common respiratory pathogens in children and adults with acute respiratory tract illness (ARTI) in Guangzhou, southern China, and to uncover clues that might help to establish clinical distinctions between different HPIV types.	./cache/cord-275211-1b56a6zc.txt	./txt/cord-275211-1b56a6zc.txt
