Why do you suppose tuberculosis was not a factor in the chart of 1997 leading causes of death when it was so destructive the in year 1990?

By 1997, significant advances in tuberculosis (TB) prevention, diagnosis, and treatment had led to a decline in its incidence and mortality rates. The introduction of effective antibiotics, improved public health measures, and better access to healthcare contributed to this decline. Additionally, the global response to TB, including increased funding and awareness, likely played a role in reducing its impact compared to the early 1990s. Consequently, TB may not have ranked among the leading causes of death in 1997 as it had in 1990.
