The compilation of this report is an important step in the provision of strategic information for the national response to the HIV epidemic. This document provides updated information on the HIV situation in the country and these data are the cornerstone for planning, resource allocation, advocacy, and HIV policy formulation, in addition to the design of prevention, behaviour change, treatment, care and support programs in Papua New Guinea. The compilation of this report satisfies one of the key objectives of the government through the National AIDS Council and the National Department of Health to provide up to date information on the HIV epidemic so that all stakeholders can access and use this information to plan and implement their response to HIV. The data used in this report were collected from STI, HIV, ANC and TB clinics, VCT sites and behavioural surveillance sites. About 4,017 people tested HIV positive in 2006; 30% more than in 2005. Sero-surveillance sites showed an increase in prevalence levels with the total number of reported HIV infections reaching 18,484 by the end of 2006. Despite the lack of comprehensive information about the age and sex of people diagnosed with HIV, as age was not recorded in one-third of the data; where age was recorded, the majority of HIV infections were in people aged between 20 and 35, with higher numbers of HIV infections found in female youth and younger women. According to the data available, the most common age at diagnosis for men is in the 25-29 and 30-34 year age groups, with 60% of all infections in males under the age of 35 and three quarters below the age of 40. More female youth and young women are diagnosed with an HIV infection at an earlier age particularly in the 20-24 and 25-29 year old groups, with 61% of infections by the age of 29, over three quarters of infections diagnosed by the age of 34, and 94% by the age of 44. The national HIV prevalence is estimated to be 1.28% among adults aged 15- 49 at the end of 2006, which means there are about 46,275 people estimated to be living with HIV. The trend of the epidemic is showing a high increase, especially in rural areas where 85% of the PNG population lives. It is projected that starting in 2007 the prevalence among the rural population will become higher than in urban areas. The new 2006 prevalence estimate, when compared to previous estimates, show that while the prevalence is lower than what has been previously estimated; the trends in the epidemic are increasing more sharply than what has been previously documented. iv Other projections in this report estimate that in 2007, 3,700 people will die of AIDS. Increased numbers of people dying of AIDS continue to impact on the vulnerability of children and youth, and it is projected that in 2007, 3730 children (0-17) will be orphaned due to AIDS. These alarming statistics are a cause of grave concern for the government and we are mobilizing all of our resources to minimize the impact of the HIV epidemic on people‟s lives in rural and urban areas.
