Read the following passage．Complete the diagram by using the information for the passage． Write NO MORE THAN 3 WORDS for each answer. United Nations officials say now fewer people than they thought are infected with the AIDS virus. Last year, the agency known as UNAIDS thought that 39.5 million people were living with HIV．On Tuesday it reduced by 16% to a little more than 33 million. Agency officials say the low number reflects better information form more countries．The agency reduced the number for five African countries: Angola, Kenya, Mozambique, Nigeria and Zimbabwe. Also, UNAIDS says it now believes the number of new HIV cases per year reached a high in the late 1990s at more than three million．This year, it thinks that 2.5 million people became infected, and 2 million people died of AIDS. Luckily, better treatments are saving lives, and m  ore people are getting the drugs.Yet even as the number of new infections has dropped, UN officials say AIDS is still one of the leading causes of the death worldwide, and the major cause in Africa．African death rates remain high, they say, because treatment needs are not being met．Sub-Saharan Africa had almost 70% of the new cases of HIV reported this year．UNAIDS officials say this is a sharp reduction since 2001, but there is a need to further improve research method. Billions of dollars are being spent preventing and treating HIV．Experts worry that the new number may le  ad to a drop in financial support．But UNAIDS officials say they do not change the need for immediate action and more money．They warn that in some countries, infection rates that were falling are rising again now．Title: A New Report on (71) Infections
