Trends
One of the major
trends in TB in Michigan has been a gradual decline in the
number of cases reported. In 2008, TB Control Program reported
185 TB cases and a case rate of 1.9 per 100,000 population.
This represents a 18.1% decrease from the number of cases reported
in 2007. TB cases in the State of Michigan have decreased
by 47.3% over the ten-year period from 1999 - 2008.
In Michigan, certain ethnic and minority
groups are disproportionately affected by TB. This is a chart
showing the percentage of disease compared to the percentage
of total population in 2005.
