Epidemiological characteristics of Cox A6 infected with hand-foot-mouth disease in children aged 1-12 years in Enshi / 公共卫生与预防医学

ABSTRACT

Objective To investigate the incidence and risk factors of severe cases of Cox A6 infected with HAND-foot-mouth disease in 1-12 years old children in Enshi city, and to provide reference for prevention and treatment of hand-foot-mouth disease. Methods From January to September 2021, hospitalized children aged 1-12 years with HFMD in Enshi city were collected. The samples of anal swabs and throat swabs were tested for Coxsackie virus A6 (Cox A6) nucleic acid, and the distribution of Cox A6 patients infected with HFMD and the proportion of severe cases in children aged 1-12 years were analyzed. Logistic regression was used to analyze the risk factors of severe cases. Results From January to September 2021, a total of 343 HFMD cases aged 1 to 12 years were reported in Enshi, among which 241 cases (70.26%) were infected with CoxA6. No death cases were reported during the period. The 241 cases of Cox A6 infected with HFMD were distributed from January to September. 129 males (53.53%) and 112 females (46.47%); 208 cases (44.40%) were mainly from 1 to 3 years old, followed by 66 cases (28.39%) from 4 to 6 years old, 45 cases (18.67%) from 7 to 9 years old, and 23 cases (9.54%) from 10 to 12 years old. Cox A6 was mainly infected with HFMD in 145 cases (60.17%) in rural areas and 96 cases (39.83%) in urban areas. 10 cases (4.15%) of Cox A6 infected HFMD were severe cases; There were significant differences in age, fever temperature, fasting blood glucose and fever time between the severe case group and the normal case group (P<0.05). Logistic multivariate regression analysis showed that fever temperature (OR=1.559, P<0.05), fasting blood glucose (OR=2.472, P<0.05) and fever time (OR=2.932, P<0.05) were independent risk factors for the occurrence of severe cases of Cox A6 infected with HFMWD in Enshi. Conclusion The incidence of Cox A6 infected with HFMD in Enshi is mainly concentrated in boys under 3 years old. Clinical treatment of HFMD children should focus on children with high fever temperature, fasting blood glucose and long fever time.
