Abstract:

To understand the work progress in nationwide control of echinococcosis, we summarize the experience and find the existing problems through descriptive analysis on the national control data in 2022. As of the end of 2022, there were 370 echinococcosis endemic counties (city, district, banner) covering 29 926 villages in China, having a total of 25 227 echinococcosis cases with an average prevalence of 58.35 per 100 000 (25 227/43 232 609), among them, 15 554 cases were of cystic echinococcosis, 8 169 cases alveolar echinococcosis, 255 mixed infection, and 1 249 cases pending; 1 270 cases were newly found, including 991 cases of cystic echinococcosis, 89 alveolar echinococcosis, 5 mixed infection, and 185 pending; revealing 102 cases were at age < 12, and 1 168 case were of age ≥ 12. In 2022, population screening by abdominal ultrasound scanning was performed in all endemic provinces (autonomous regions) for 3 576 121 person/times. Of them, 751 440 person/examinations were performed for the residents younger than 12, and 2 824 681 person/times were performed for residents older than 12. The serological examination was carried out for the suspected individuals for 17 404 person/times. According to data from 370 surveillance sites in 2022, the prevalence in residents younger than 12 was 0.02% (60/287 437) by ultrasound screening, with 40.00% (24/60) newly diagnosed cases. The prevalence in the residents older than 12 was 0.29% (772/270 407) in type Ⅰ and type Ⅱ endemic counties (city, district, banner). The newly diagnosed cases accounted for 8.29% (64/772) of the detected patients. In 2022, 18 354 patients received drug treatment, of which 16 625 patients received liver and kidney function tests or management against adverse reactions. A total of 1 418 patients received surgical treatment, including 69.82% (990/1 418) for cystic echinococcosis, and 26.52% (376/1 418) for alveolar echinococcosis. In 2022, the follow-up results showed that 999 cases were cured, 20 599 cases responded to the treatment, 2 546 cases failed in the treatment, 374 cases died (the causes of the deaths were not echinococcosis), 239 cases were excluded, 372 cases were lost in follow-up, 884 cases had not completed the follow-up, and 170 cases migrated to other places. In 2022, there were 2 478 608 dogs in the endemic townships (towns) nationwide, of which 2 250 694 were registered for management. Deworming work was conducted for dogs in 34 646 villages, with 24 289 457 deworming times. Wild canines were demormed by delivering 119 473 drug doses. A total of 394 851 fecal samples from domestic dogs were collected and detecteded, of which 1 756 were found positive for Echinococcus coproantigen, with a positive rate of 0.44% (1 756/394 851). Of the wild canines, 62 884 field fecal samples were collected and detected, among which 1 201 were found positive for Echinococcus coproantigen, with a positive rate of 1.91% (1 201/62 884). A total of 117 303 slaughtered livestock were randomly examined, among which 1 038 were diseased, with a prevalence of 0.88%. A total of 43 705 field rodents were examined, among which 403 were diseased, with a prevalence of 0.92%. Although the endemic of echinococcosis in China has been essentially controlled, there remain many difficulties and challenges in control work. It is imperative to continuously strengthen the prevention and control measures for echinococcosis, raise the disease prevention awareness, explore optimizing the control strategy, exert the role of regional joint prevention and control mechanisms and fully implement comprehensive measures to further control the prevalence of echinococcosis.
