** Globally, tuberculosis "kills around 2 million people each year. One-third of the world's population is currently infected with TB and someone is newly infected every few seconds. . . . TB is the leading cause of death among HIV infected people; the WHO estimates that TB accounts for up to a third of AIDS deaths worldwide" ("AIDS, HIV, & Tuberculosis (TB)" <http://www.avert.org/tuberc.htm>). -- Yoshie
