Many Nigerians remain ignorant about Aids. Nigeria has one of the world's highest numbers of people living with the Aids virus, the health minister has said. Eyitayo Lambo said that some 2.3m Nigerians have already died from Aids, while 3.8m were HIV- positive. Only South Africa and India have more people infected with HIV. The rate of Aids infection is much lower in West Africa than in southern Africa, where 30% of the population of some countries is HIV positive. Nigeria - Africa's most populous country, with some 130m people - has been criticised for not doing enough to fight Aids.
