Introduction
Analysis of the core framework of the standard
This standard constructs a two-level prevention and control system: epidemic control (basic requirements) and transmission control (advanced goals). The technical indicators are designed based on the epidemic characteristics of echinococcosis in my country, focusing on monitoring the results of ultrasound diagnostic instruments and animal host infection data.
| Assessment dimensions | Epidemic control threshold | Transmission control threshold | Detection method |
|---|---|---|---|
| Residential prevalence | <1% | - | WS 257 diagnostic criteria |
| Children's prevalence | - | <1‰ | Abdominal ultrasound examination |
| Canine infection rate | <5% | <1% | Autopsy/arecoline catharsis |
Operational specifications for key indicators
1. Technical requirements for population screening
When using portable ultrasound equipment for examination, please note:
- The examination rate for residents must be >80%, and for children >95%
- Liver scans use intercostal oblique sections, and the diameter of the cyst must be recorded to the nearest mm
- Serum samples must be collected from suspected cases for immunological review
2. Key points for animal host monitoring
The arecoline hydrobromide catharsis method is recommended for canine testing:
- Administer the drug (4 mg/kg) after fasting for 12 hours
- Collect all feces within 2 hours
- Use the sedimentation method to examine the protoscolex under a microscope
Recommendations for the implementation of the standard
Application Cases in Qinghai Province
The "three deworming and two inspections" model was adopted in Yushu Prefecture:
- Quarterly dog deworming (praziquantel 5mg/kg)
- Mandatory organ inspection in slaughterhouses
- Annual screening of school-age children
File management specifications
An electronic database needs to be established, including:
- Dog registration and deworming records
- Case follow-up data (updated every 6 months)
- Original records of intermediate host detection
