[Study on the epidemiological characteristics and strategy of surveillance in low endemic areas of malaria in Hubei].
Due to good programs on case finding and control, malaria has decreased to a low level in China. Hence, the existing surveillance program of undertaking blood smear from cases with fever finds very few positives in the millions of examinees. Previously, all blood slides were collected from clinically diagnosed cases of malaria (group 1), suspected malaria cases (group 2), fever of unknown reasons (group 3) or common cold (group 4) in low or moderate malaria endemic areas in Hubei Province. In low prevalence areas, the positive rates on slides were 0.6/10,000 and 0.1/10,000 in group 3 and group 4 while 95.38% of the confirmed malaria cases were from those having clinical malaria or suspected malaria. It is suggested that group 3 and group 4 be dropped from low prevalence areas to encourage greater efficiency in case detection in the clinical and the suspected malaria groups.
