Identification of hot spots (The background map shows the survey area divided into 61 clusters. Cluster 56 is excluded from the New Nets pilot surveys. The Kulldoff scanning method identifies clusters of malaria incidence with 95% confidence. These clusters are shown as circles. A hotspot is indicated by a red circle. If there is at least one red-marked child’s home in a survey cluster in this hot spot, it is considered a hot cluster. Cold zones are indicated by nothing or by black circles with the child's home in black)
