The line graph depicts the figure for new cases of Measles, Rubella and Mumps over a thirteen-year period from 1991. Overall, there was a gradual increase in the number of new cases of Measles and Rubella. In contrast, the number of patients of Mumps rose significantly over the period.
Regarding Measles, its figure for new cases remained stable at around 12 thousand from 1991 to 1993 before reaching a peak of nearly 25 thousand in 1994. Following this, the number fell tremendously to 10 thousand in the next year. After that, there was a downward fluctuation between 10 thousand and 4 thousand from 1995 to 2004. Similarly, looking at Rubella, its figure fluctuated between around 10 thousand and 12 thousand cases from 1991 to 1996. Consequently, from 1996 to 1997, the number of new cases witnessed a significant drop to 5 thousand. It then continued to experience a slight decrease to 2. 5 thousand in the next 8 years, accounting for the lowest figure.
As the graph showed, the number of patients of Mumps remained stable at around 4 thousand from 1991 to 2002 before reaching a peak of 22 thousand cases, accounting for the highest statistic in 2004.
