ABSTRACT

@#Abstract:Objective To investigate the detection methods of newly discovered leprosy cases in Hunan Province in 2013-2022, and analyze the trend of changes, and provide scientific basis for the prevention and treatment of leprosy. Methods The detailed information of newly diagnosed leprosy cases in Hunan Province from 2013 to 2022 was collected through the Leprosy Management Information System (LEPMIS), and the descriptive epidemiological method was used to analyze the detection methods of newly discovered leprosy cases. Results From 2013 to 2022, a total of 250 newly diagnosed leprosy cases were detected in Hunan Province, including 143 cases (57.20%) were found in outpatient clinics, 33 cases (13.20%) were found in clue investigations, 27 cases (10.80%) were notifiable-reported, 23 cases (9.20%) were self-reported, 11 cases (4.40%) were found in other ways (e.g., group survey), 9 cases (3.60%) were found in contact examinations, 2 cases (0.80%) were found in census, and 2 cases (0.80%) were found in epidemic point inspection. From 2013 to 2022, the number of cases detected in outpatient clinics showed an upward trend (rs=0.515), while the cases detected in clue investigation (rs=-0.873), notifiable-reported (rs=-0.127), self-reported (rs=-0.301), contact examination (rs=-0.363), census (rs=-0.701) and epidemic point inspection (rs=-0.701) showed a downward trend. The majority of leprosy cases with different demography characteristics and clinical characteristics were found through outpatient clinics, except that the majority of leprosy cases in children were found by contact examination (66.76%). Of 165 male cases, 92 cases (55.76%) were found in outpatient clinics and 51 out of 85 female cases (60.00%) were found in outpatient clinics. Among age groups, 113 out of 187 cases aged 15 to 60 (60.43%) and 30 out of 60 cases aged over 60 (50.00%) were found in outpatient clinics. Among patients with differentoccupations, 112 out of 208 cases of farmers (53.85%) and 31 out of 42 cases of other occupations (73.81%) were found inoutpatient clinics. Among cases with different types of leprosy, 111 out of 185 cases of multibacillary leprosy (60.00%) and 32 out of 65 cases of paucibacillary leprosy (49.23%) were found in outpatient clinics. Among cases with different numbers of skin lesions, 4 out of 8 cases of skin lesion-free leprosy (50.00%), 3 out of 9 cases of single skin lesion leprosy (33.33%), and 136 out of 233 cases of multiple skin lesions leprosy (58.37%) were found in outpatient clinics. Of 72 cases without nerve damage, 48 cases (66.67%) were found in outpatient clinics. Of 27 cases with single nerve damage, 17 cases (62.96%) were found in outpatient clinics. Of 151 cases with multiple nerve damage, 78 cases (51.66%) were found in outpatient clinics. Among patients with different levels of malformation, 58 out of 102 cases with no malformation (56.86%), 28 out of 45 cases with Grade malformation (62.22%), 35 out of 68 cases with Grade Ⅱmalformation (51.47%), and 22 out of 35 cases with other types of malformation (62.86%) were found in outpatient clinics. Conclusions Outpatient clinics is the main way to detect newlydiagnosed leprosy cases under the low prevalence of leprosy in Hunan Province, and it is an important strategy to move the early detection of leprosy cases to comprehensive medical institutions in the future.

ABSTRACT

Objective@#To understand the characteristics of HIV/AIDS epidemic in Guangxi Zhuang Autonomous Region (Guangxi) with a purpose to accurately provide scientific basis for prevention and control measures, 2010-2017.@*Methods@#Data were retrieved from case reporting cards of Guangxi during 2010 to 2017 through National HIV/AIDS Comprehensive Response Information Management System. Data was analyzed using epidemiological methods such number of cases, proportion and rate. χ2 test was used for statistical analysis.@*Results@#The HIV positive rate was 12.53 per ten thousand (85 182/67 959 000) in Guangxi during 2010 to 2017. The number of newly diagnosed HIV/AIDS cases and the number of death yearly respectively increased by 22.34%(2 602/11 648) and 32.83% (952/2 900) in 2011 compared with 2010, and both showed a six-year continuous downward trend (the number of newly diagnosed cases respectively 12 229 cases, 10 877 cases, 9 460 cases, 9 190 cases, 8 848 cases, 8 680 cases, and the number of death respectively 3 888 cases, 3 316 cases, 2 914 cases, 2 717 cases, 2 595 cases, 2 600 cases) from 2012 to 2017. But proportion of late discovery remained above 50.00% (50.53%-57.06%) for eight-years continuously. The ratio of male and female was 2.47 ∶ 1 (60 639/24 543). The ratio of males and females aged 50 and over was 2.71∶1 (28 654/10 557). Proportion of the cases in 25-49 years old group and 50 years old group accounting for 47.40%(40 377/85 182) and 46.03% (39 211/85 182) respectively. The occupation was farmers accounting for 68.40% (58 262/85 182), housekeeping, housework and unemployment accounting for 11.21% (9 546/85 182), student accounting for 0.86% (729/85 182). Heterosexual transmission accounted for 90.60% (77 171/85 182, homosexual transmission accounted for 3.13% (2 669/85 182), injection drug use transmission accounted for 4.60%(3 924/85 182) and mother-to-child transmission accounted for 0.73% (619/85 182).@*Conclusions@#The number of newly diagnosed cases and the number of death yearly showed a continuous downtrend for six-years from 2012 to 2017. However, proportion of late discovery remained above 50.00% for eight-years. The major route of infection was heterosexual transmission. With the change of HIV/AIDS newly epidemic mode in Guangxi, there are many new challenges for HIV/AIDS prevention and control work. Strategy of targeted intervention modes should be innovated for a new breakthrough.
