Papua New Guinea's Department of Health and National AIDS Council Secretariat believe that the nation's HIV/AIDS prevalence is 0.92% - a figure which continues to rise.
A study conducted in 2009 led to the latest estimate, taking into account the most recent available data from across the country.
The HIV/AIDS prevalence study was carried out by a panel of national and international experts, who used information from tests of pregnant women from antenatal clinics in Papua New Guinea's four regions.
In June a joint Department of Health and National AIDS Council Secretariat workshop collected and finalised the results.
From 2007 onwards, officials have been noting higher estimates of prevalence based on data from a relatively small number of urban and rural sites.
The number of health facilities conducting HIV/AIDS tests among antenatal mothers has increased, offering sufficient data to get a more accurate picture of the epidemic among 15 to 49-year-olds last year.
