THE Tanzanian government has stopped importing chloroquin because of the increased resistance of the malaria-causing parasites to the drug. Deputy Health Minister Tatu Ntimizi has said. Ntimizi told parliament at Dodoma in central Tanzania on Tuesday that government-owned medical stores were no longer mporting chloroquin anti-malarials. Official records show that Malaria is Tanzania’s leading killer disease, accounting for more than 50 percent of clinical cases reported daily at dispensaries and health centres. But Ntimizi told parliament the level of resistance to chloroquin was in some cases above 50%, the independent Guardian newspaper reported.
