Abstract: A retrospective analysis was performed on 47 children diagnosed with paragonimiasis in Ningbo Women and Children’s Hospital from January 2004 to December 2014. The 47 children comprised 32 boys （68.1%） and 15 girls （48.9%）, and 24 cases（51.1%） in urban areas and 23 （48.9%） in rural areas （P>0.05）. There was a trend of increase in paragonimiasis occurrence in preschoolers since 2010. Forty-three cases had a history of eating raw or wine-preserved crabs and 4 cases had a history of drinking raw stream water． There were 2 cases of paragonimus encephalopathy and one case accompanied by subcutaneous nodules. Thirty-nine cases showed increases in eosinophil number and proportion in peripheral blood, and 29 cases showed increased serum IgE level. Forty-seven cases had negative results for detection of paragonimus eggs in sputum and stool. The dot immuno-gold filtration-assay and ELISA showed a 100% positive rate for paragonimus serum antibody. All the 47 cases were administered with praziquantel after diagnosis, and no adverse effect was reported during the treatment.
