Figure 1.1 illustrates the various aspects of hygiene and environmental health that are described in Table 1.1. Look at the separate drawings within the figure and match each of them to one of the descriptions.
Starting at top right, the drawing there illustrates solid waste disposal in a pit. Below that is a woman cooking at a stove to show food hygiene in a cooking area. The handpump illustrates water supply. Personal hygiene is represented by the person washing themselves. The next drawing shows a storage cupboard, again illustrating food hygiene. The drawing at top left is a pit latrine to represent human waste disposal. The central drawing illustrates healthful housing. (Vector control, institutional hygiene, occupational hygiene and water pollution are not shown.)
