Human Coronavirus NL63 Infection and Other Coronavirus Infections in Children Hospitalized with Acute Respiratory Disease in Hong Kong, China	2005-06-15		.txt	text/plain	3944	220	56	In 2001 and 2002, we performed prospective clinical and virological studies of children (age, р18 years) with acute respiratory tract infection who were admitted to Queen Mary Hospital (Hong Kong, China). We studied a systematic sample of children (age, р18 years) with acute respiratory infection admitted to Queen Mary Hospital during the period from August 2001 to March 2002. One child with HCoV-NL63 upper respiratory tract infection had positive results of only the consensus primer PCR, so no viral load could be measured. We documented that human coronavirus infection was a significant cause of hospitalization for children aged р18 years, accounting for 4.4% of all admissions for acute respiratory infections. A previous study showed that 8.2% of children aged !18 months who were admitted to a Chicago, Illinois, hospital with lower respiratory tract diseases had serological evidence of HCoV-229E or HCoV-OC43 infection [13] .	./cache/cord-301066-62qe4fb0.txt	./txt/cord-301066-62qe4fb0.txt
