Abstract:
Objective To analyze the epidemiological characteristics of malaria in Nanjing City,so as to provide the evi?dence for further formulating and adjusting the malaria prevention and control strategy. Methods The data of malaria situation, malaria cases and epidemiological investigations were collected from the Internet Reporting System in Nanjing City from 2010 to 2015 and analyzed statistically. Results A total of 137 confirmed malaria cases were reported in Nanjing City from 2010 to 2015,including 102 falciparum malaria cases(74.45%),33 vivax malaria cases(24.09%),one ovale malaria case(0.73%) and one quartan malaria case(0.73%). Among the 137 malaria cases,126 cases(91.97%)were imported from foreign coun?tries,2 cases(1.46%)were infected locally,and nine cases(6.57%)were imported from other provinces in China. Among the 126 overseas imported cases,117 cases were imported from African countries and 9 from Asian countries. These malaria cases were majorly young men working as migrant workers,laborers and technical persons. About 19.30%of the cases went to hospital on onset day,and 55.65%were confirmed by medical institutions as malaria in the same day. The majority of diagnosis institu?tions were municipal hospitals(74.45%). Conclusions The number of malaria cases in Nanjing City is declining year by year. The local infections are eliminating gradually. However,the situation of imported malaria from overseas is still serious. There?fore,the surveillance work and health education still should be strengthened,so as to reduce the risk of imported malaria.
