Trends in the leprosy point prevalence rate and NCDR from 2000–2014.
The point prevalence rate declined from 0.94/10,000 in 2000 to 0.20/10,000 population in 2014 (P<0.001) accounting for a 78% reduction. Similarly the annual NCDR declined from 4.88/100.000 population in 2000 to 1.46/100.000 population in 2014 (P = 0.018) accounting for an 85.3% reduction. However, two peaks in annual NCDR were noticed in 2002 and 2006 with annual NCDR of 9.96/100,000 and 4.29/100,000 population respectively.

Trends in leprosy detection indicators in Cameroon from 2000 to 2014.
The MB proportion was high ranging from 62% to 87%. The G2D proportion remained below 10% throughout the 15-year period. Although the child proportion generally ranged between 10% and 20%, there was a rising tendency from 2008. The Female proportion was fluctuating though with a general rising tendency to reach an acceptable level of 40%.

Trends in the number of leprosy endemic regions and health districts in Cameroon from 2000 to 2014.
Panel A shows the trend in the number of regions of Cameroon, out of a total of 10 regions, with a point prevalence rate per 10,000 population of more than 1. Panel B shows the trend in the number of HDs of Cameroon, out of a total of 181 HDs, with a point prevalence rate per 10,000 population of more than 1. At the end of 2014, leprosy elimination was achieved in all 10 regions; and is still to be achieved in 10 HDs.

Trend in G2D rate per 100.000 population.
The G2D rate decreased slightly from 0.133/100.000 population in 2010 to 0.105/100.000 population in 2014, constituting a 21% reduction.
Fig 5.
Five-year-interval trend in leprosy burden map of Cameroon by region from 2000 to 2014.
In 2000, 8 out of 10 regions in Cameroon were high-leprosy-burdened and one medium-burdened. By 2005 this number decreased to 6 and then to 5 in 2010, and further to 1 in 2014.
Fig 6.
Five-year-interval trend in leprosy burden map of Cameroon by health district from 2000 to 2014.
The number of high-leprosy-burdened districts dropped from 68 in 2000 to 18 in 2014. During the same period, the number of medium-burdened districts also witnessed a drop from 31 to 20. The reduction in the number of both high and medium-burdened health districts was gained by low-leprosy-burdened districts that rose from 82 in 2000 to 143 in 2014.
