This figure shows the notification rates for both combined and separate categories of non-congenital syphilis infections in Australia, from 2009 to 2014. The figure illustrates the notification rates of infectious syphilis, less than two years duration, and the notification rates for syphilis of more than two years or unknown duration. The figure demonstrates that for infectious syphilis, notification rates within the 2009 to 2014 period reached their minimum in 2010 and maximum in 2014. For syphilis of more than two years or unknown duration, notification rates were at their lowest in 2012 and highest in 2014.
