Dec. 1 marks World AIDS Day. It's a time to remember over 35 million people who have died from the disease since the early-1980s and show support for those who are struggling with it now. It's also a chance for health organizations and charities to raise awareness about testing and treatment. [...] Across the globe, approximately 34 million people suffer from HIV/AIDS, including more than 1.2 million who live in the United States.
