Abstract:
Objective To learn the clinical manifestations and pathogenic situation of hand foot and mouth disease (HFMD) in Changchun children's hospital from 2009 to 2010.Methods We collected the faeces specimen and oropharyngeal swabs of 1 862 children patients who consulted in Changchun children's hospital from May 2009 to Nov 2010.The enterovirus 71 ( EV71 ) and Coxsackie virus A16 (CoxA16) of 1 514 faeces specimens were amplified with RT-PCR,and 530 oropharyngeal swabs' virus were isolated with rhabdomyosarcoma cell.Results The total HFMD patients were 1 175 in 2010,687 in 2009.The rate of serious patients was 6.26％ (43/687) in 2009,and 16.51％ ( 194/1 175 ) in 2010.The season of peak incidence in 2009 was June,and in 2010 were June,July and August.The gender distribution was 1 241 males and 621females.The average age of HFMD patients was ( 28.32 ± 15.22 ) months.And the distribution in city and countryside was 1:1.05.Total of 1 862 cases ( 100％ ) had rash,55.69％ ( 1 037/1 862) had fever,6.07％(113/1 862) had neurologic symptom and 1.41％ (26/1 862) had vomiting when the patients admitted in our hospital.And there were 547 cases ( 29.41％ ) emerging myocardium injury,548 cases (29.43％ ) emerging neurologic complications and 82 cases (4.39％ ) emerging respiratory complications during treatment.There were 166 positive with positive rate 31.32％ in virus isolation.The positive rate of EV71 and CoxA16 were 9.62％ and 10.57 in 2009,and 32.52％ and 39.53％ in 2010.Conclusion There were more HFMD patients in 2010 than 2009,and the proportion of serious patients was increased too.In summer and autumn,we should pay more attention to HFMD for fever children.HFMD could damage digestive system,respiratory system,circulatory system and nervous system.The nervous system of serious patients is more likely to be damaged.The pathogens of HFMD are diversity,but mainly are EV71 and CoxA16,and the pathogen of serious patients is mostly EV71.
