X-axis labeled year starts with 1991 to 2007 in two-yer increments. Y-axis labeled number of reported cases (in thousands) starts with 0 to 105 in increments of 15. The line begins at 90 in 1991 then dips and rises again several times until it reaches 75 in 1997. The line then falls steadily to approximately 15 in 2007
