It is estimated that over 40 million people are living with HIV worldwide and around three million people die from AIDS each year. AIDS develops when the immune system has been weakened by the HIV virus and can no longer fight infections. How is HIV transmitted and how can it be prevented? This book looks at the AIDS epidemic globally and at HIV and AIDS in the UK. The information comes from a variety of sources, including government reports and statistics, newspapers and magazine articles, surveys and polls, academic research and literature from charities and lobby groups; articles have been tailored to an 11 to 14 age group. Additionally, at the end of each chapter are two pages of activities relating to the articles and issues raised in that chapter.
