適用範囲

This standard specifies the requirements for achieving the elimination of filariasis and is applicable to the surveillance and certification of disease control outcomes. It specifically applies to 16 provinces, autonomous regions, and municipalities in China that historically had filariasis endemic areas, including Shandong, Henan, Anjiang, and Hainan. It is intended for use by public health authorities and disease control institutions to verify regional elimination status.

技術要求

The standard establishes the criteria for confirming the elimination of lymphatic filariasis. It mandates that a region must have been certified as basically eliminating filariasis (with the microfilaria rate dropping below 1% at the administrative village level) for over 10 years. Following this period, strict post-elimination surveillance must demonstrate zero positive cases. Specifically, parasitological surveillance must show no microfilaraemia carriers, and entomological surveillance must confirm no human filaria larvae infections in vector mosquitoes. Additionally, there is a recommended requirement to investigate and provide care for remaining chronic filariasis patients, though this does not affect the overall elimination certification as these patients are no longer transmission sources.

試験方法

The evaluation involves two primary surveillance methods: parasitological monitoring and entomological monitoring. Parasitological surveillance requires night-time blood collection (120 μL per person) to create thick blood smears for microscopic examination, covering specific percentages of the endemic population and townships. Entomological surveillance involves capturing and dissecting specific vector mosquito species (such as Culex pipiens pallens or Anopheles sinensis) from human dwellings to check for larvae infection. Strict sampling and cumulative coverage thresholds are defined in the normative appendix to validate the surveillance results.

よくある質問

What regions and diseases are regulated under GB 20048-2006?

This standard applies to 16 specific provinces, autonomous regions, and municipalities in China that historically had lymphatic filariasis endemic areas. It is used to assess and certify whether these regions have successfully eliminated the disease.

How does GB 20048-2006 define the elimination of filariasis?

The standard requires that a region has maintained a microfilaria rate below 1% for over 10 years, followed by continuous parasitological and entomological surveillance showing zero positive cases. It is a strict, multi-year post-elimination certification process.

Are chronic filariasis patients considered a transmission risk under this standard?

The care for chronic filariasis patients is a recommended requirement rather than a mandatory one. Because these patients no longer act as transmission sources, failure to fully meet this clause does not prevent a region from being certified as having eliminated filariasis.
