This year's World AIDS Day is an occasion to recognize the burden that women and girls bear in the age of HIV/AIDS, but equally, to celebrate their achievements in the fight against the epidemic. Women are our most courageous and creative champions in the fight against HIV/AIDS. In most countries and communities I have visited around the world, it is women's voices that are heard above all others; women advocates and activists who are moved to act selflessly and speak publicly, often risking prejudice, abuse or violence, in order to improve the lives of others.
