Sickness and Disease: Although progress has been made in ensuring an effective health care system in African states, Africa as a whole still suffers major problems as the scourge of sickness and disease. Talk of the recent outbreak of Yellow Fever in Angola, which is feared to have killed hundreds in Angola and is now spreading to the Congo, where it has already claimed the lives of 21 persons; talk of the outbreak of the deadly Ebola virus in West Africa, which claimed the lives of thousands. Malaria-related deaths and HIV/AIDS transmission levels have reduced in some places, but they continue to affect millions.
