Need biology help with Tuberculosis in a social context paper

Tuberculosis causes nearly 2 million deaths worldwide each
year. Between 1985 and 1992, cases of TB in the United States increased by 20
percent. Write a paragraph suggesting a few reasons why this resurgence of TB
might have occurred in the United States. 
The resurgence lasted until approximately 1992, then, in the United
States, it began to abate. In 2005 the TB case rate in the U.S. was 4.8 per
100,000, as the U.S. medical community brought the epidemic under control (Centers
for Disease Control & Prevention, National Prevention Information Network,
n.d.). However, in U.S. prisons and all over the world TB remains a serious
health problem. In the U.S., zero tolerance drug laws have resulted in a
burgeoning incarcerated population, which constitutes a significant reservoir
of disease, with a far higher incidence rate than the general population. In
New York prisons, the incidence rate of TB is 156.0/100,000 compared to the
rate of 10.4/100,000 in the general population (U.S. Agency for International
Development, 2009). Considering all you have learned, discuss why these rates
may be so much higher in prison.
