Figure 1.1 Trachoma prevalence in children aged 5-9 years in at-risk communities in Australia, 2013

Figure 1.1 is a map of Australia, illustrating the trachoma prevalence in children 5-9 years. Data was provided by the Northern Territory, Western Australia, South Australia and New South Wales.
Queensland, New South Wales (except for the Western region), Victoria, Tasmania and the South West corner of Western Australia are considered to be areas not at-risk of trachoma or where no data has been collected. 
The Western New South Wales region had less than 5 % trachoma prevalence identified. In South Australia the Far North region and the York and Mid North region had no trachoma identified; the Eyre and Western region had less than 5 % Trachoma prevalence; and the Anangu Pitjantjatjara Lands had greater than 10 % but less than 20 % trachoma prevalence. In Western Australia the Kimberley, Pilbara and Midwest regions had less than 5% trachoma prevalence; and the Goldfields region had greater than or equal to 5% but less than 10% trachoma prevalence. In the Northern Territory for the regions of Darwin Rural, East Arnhem, Katherine and Barkly less than 5% trachoma prevalence was identified; and the Alice Springs Remote region had greater than 5% but less than 10% of trachoma prevalence identified.

Figure 1.2 Number of communities at risk, by year and jurisdiction, Australia, 2007–2013

Figure 1.2 is a line graph illustrating the number of communities’ at–risk of trachoma between 2007 to 2013 in the Northern Territory (NT), South Australia (SA), Western Australia(WA) and New South Wales(NSW). 
The data for: NT indicates a slight decreasing trend from 85 communities in 2007 to 80 communities in 2013; SAs trend hovers around 70 communities at-risk for 2007 to 2011 and then declines to 38 communities in 2012 and 22 communities in 2013; WA shows a gradual increasing trend from 72  communities in 2007 to 86 communities in 2010, then decreases to 71 communities in 2013; NSW shows 10 communities potentially at-risk in 2013. NSW has been designated as ‘potentially at risk’ for the mapping exercise.

* In 2013 NSW communities have been designated as “potentially at risk” for the purposes of a mapping exercise

Figure 1.6 is a line graph showing trachoma prevalence trends in the Northern Territory (NT), South Australia (SA), Western Australia (WA) and New South Wales (NSW) for the years 2007 to 2013. The data shows: NT’s prevalence spikes at 26% in 2008, remains consistent at 15% in 2007, 2009 and 2010 and decreases to 4% in 2012 and increases slightly to 5% in 2013.
SA’s prevalence dips to 2% in 2008, remains at 15% for 2007 and 2009, and decreases to 2% in 2012 and increases to 3.5% in 2013. WA has a consistent prevalence of 15% for 2007 to 2009 with a decreasing trend to 3.8% for 2013. NSW data was only collected for 2013, where there was 0.5% of trachoma prevalence reported.

* Including communities in the Northern Territory that screened in 2013 and those that did not screen in 2013 in accordance with revised guideline instructions (see methodology)

Figure 1.8 Number of communities according to number of years* of trachoma prevalence under 5%, by jurisdiction* in Australia, 2013

Figure 1.8 is a histogram showing  the number of communities by the number of years for which trachoma prevalence has been kept under 5% for the Northern Territory (NT), South Australia (SA), Western Australia (WA) and New South Wales (NSW)
The data  illustrates: 
For the NT there are: 5 communities with trachoma prevalence under 5% for 1 year; 9 communities with trachoma prevalence under 5% for 2 years; 13 communities with trachoma prevalence under 5% for 3 years; 4 communities with trachoma prevalence under 5%  for 4 years and 11 communities with trachoma prevalence under 5%   for 5 years. 
For SA there are: 2 communities with trachoma prevalence under 5% for 1 year; 1 communities with trachoma prevalence under 5% for 2 years; Nil communities with trachoma prevalence under 5% for 3 and 4 years and 2 communities with trachoma prevalence under 5% for 5 years.
For WA there are: 11 communities with trachoma prevalence under 5% for 1 year; 15 communities with trachoma prevalence under 5% for 2 years; 8 communities with trachoma prevalence under 5% for 3 years; 10 communities with trachoma prevalence under 5% for 4 years and 3 communities with trachoma prevalence under 5% for 5 years. 
For NSW there is only 9 communities with trachoma prevalence under 5% cases for 1 year 
It is recommended in the footnotes that the Methodology section be read in accordance with these charts.

* 5 years with a prevalence below 5% classifies a community as not at risk of trachoma

*In the NT whole-of-community treatment was guided by the 2014 guidelines. This is defined as the treatment of all people in the community weighing > 3 kg and living in households with children < 15 years of age. In WA and SA whole-of-community treatment was guided by the 2006 guidelines. This is defined as active cases, household contacts and all children in the community aged 6 months to 14 years.
