The number of tuberculosis cases in Tanzania has risen from 39,000 a decade ago to 64,200 in 2005, a trend blamed on high HIV/AIDS prevalence, the Health Minister, David Mwakyusa, said on Thursday. "Research conducted in many parts of the country by the Ministry of Health between 2003 and 2004 established that HIV/AIDS contributes to increased TB cases by about 60 percent," the minister said.
