The Joint UN Programme on HIV/AIDS (UNAIDS) on Wednesday marked Zero Discrimination Day with a Make Some Noise campaign urging people to speak up against discrimination. Discrimination takes many forms and can be based on race religion gender sexual orientation or age Xinhua news agency quoted UN spokesman Stephane Dujarric as saying. For this year's campaign UNAIDS is putting particular focus on the need for zero discrimination in health-care settings Dujarric added. According to UNAIDS people living with disabilities are nearly three times more likely to be denied health-care than other people. Healthcare settings should be safe and supportive environments.
