The World Health Organisation has said global efforts to overcome tuberculosis are making steady progress but serious problems remain in tackling the disease in Africa.
In a new report, the UN body said the disease had reached alarming proportions on the African continent, where co-infection with the HIV virus makes a lethal combination.
The WHO's Director-General, Dr Lee Jong-wook, said the rate of TB infections had tripled in some African countries since 1990.
