The number of Aids victims is growing day by day and today there is an estimated number of about 40 millions living with HIV/AIDS. In South-East Asia, Cambodia has the highest prevalence of HIV/AIDS affected victims. This situation is alarmingly increasing every year. The national response is necessarily limited by the destruction of the health system under the Pol Pot regime and is under-funded since that time. National and Local governments rely heavily on NGOs to help with the awareness building and access to treatments. Work on HIV/AIDS is a key area of work for Caritas Network and in particular for Caritas Cambodia. It is with a sense of urgency that Caritas Cambodia has included the response to AIDS victims as a priority.
