Summary: | BACKGROUND:A few new leprosy cases still can be seen in Shandong province after elimination. In post-elimination era, government commitments dwindled and active case-finding activities were seldom done. Most of the cases were detected by passive modes and advanced cases with longer delay and visible disability were common. MATERIALS AND METHODS:Comprehensive measures including health promotion, personnel training, reward-offering, symptom surveillance and a powerful referral center were implemented in the past decade. The diagnosis of leprosy was mainly based on three cardinal clinical signs. Two-group classification system developed by the WHO was used and cases were classified into multibacillary (MB) type or paucibacillary (PB) type. Cases detected during period 2007-2017 were analyzed and associated factors of grade 2 disability (G2D) were explored. RESULTS:231 new leprosy cases detected during 2007-2017 were analyzed. The mean age at diagnosis is 51.7±16.0 years and the number of males, peasants, illiterates, MB cases, G2D cases and immigrants were 130(56.3%), 221(95.7%), 73(31.6%), 184(79.7%), 92(39.8%) and 40(17.3%) respectively. 181(78.4%) cases were reported by skin clinics and 152 (65.8%) cases came from formerly high endemic counties/districts. The annual number of new cases showed a decreasing trend, from 42 cases in 2008 to 13 cases in 2017. 92 (39.8%) cases presented with G2D at diagnosis. The annual proportion of new cases with G2D declined from 50% in 2008 to 23% in 2017. PB type (OR = 2.76, 95% CI, 1.43-5.32), >12 months of patient delay (OR = 2.40, 95% CI, 1.38-4.19), >24 months of total delay (OR = 4.35, 95% CI, 2.33-8.11), detected by non skin-clinic (OR = 3.21, 95% CI, 1.68-6.14), known infectious source (OR = 1.77, 95% CI, 1.01-3.12) were associated with G2D. CONCLUSION:A few scattered cases still can be seen in post-elimination era and some kind of leprosy control program is still necessary. Government commitments including adequate financial security and strong policy support are ... |
