Analysis of factors for early reporting of imported malaria cases

Abstract

Abstract:

From 2012 to 2016, a total of 159 imported malaria cases were reported, predominated by falciparum malaria (76.1%, 121/159).The average time interval from disease onset to diagnosis was 4.07±6.74 days.Sixty-one cases (38.4%) first visited medical units, while 66.7% (106/159) were diagnosed in CDCs, and 64.8% (103/159) visited hospitals after disease onset.Univariate analysis identified the way of going abroad, a history of malaria, the origin of imported malaria, medical unit of first visit, the way of case-finding, and malaria onset type as factors for early reporting of malaria.Multivariate analysis identified the place origin of imported malaria, medical unit of first visit, the way of case-finding as factors for early reporting of malaria.

Key words: Import malaria, Finding pattern, Factor
