||Many people still die from TB, even though it is curable. It
costs about US$2,000 per patient to treat. (The cost for Multi-Drug Resistant-TB rises to
more than US$250,000 per patient.)
TB control is difficult, which is why it is still an
important cause of death. Currently, the principal control strategy for those with TB is
contact-tracing and DOT (Directly Observed Therapy, to ensure patients complete treatment
). DOT both maximizes cure-rates and minimizes the risk of encouraging drug-resistant
strains of TB bacilli.
