Adapting the local response for malaria elimination through evaluation of the 1-3-7 system performance in the China-Myanmar border region

Objectives

An assessment of the ‘1-3-7’ performance in the Yunnan Province border region was conducted to identify the gaps and challenges of the system with a focus on reactive case detection (RACD)-related activities. The ways to optimize the response strategy to the local Yunnan setting were explored to promote malaria elimination in the study areas.

Rationale and Abstract

The National Malaria Elimination Programme (NMEP) strategy in China is a surveillance and response system for case reporting, investigation, and follow-up response known as ‘1-3-7’: reporting of malaria cases within 1 day, case confirmation and investigation within 3 days, and appropriate foci response to prevent potential local transmission within 7 days. The ‘1-3-7’ strategy was rolled out nationally in 2012 and is an important and simple set of targets for local Centers for Disease Control and Prevention at the country level to follow.

Previous assessments of the ‘1-3-7’ targets identified gaps in reporting in the malaria information system, particularly in Yunnan Province. Furthermore, recent field investigations indicated that malaria active case detection practices (including RACD) varied widely from county to county.

Study Design

A total of four counties (Genma, Longchuan, Tengchong, Yingjiang) out of 18 total border counties were identified with three townships randomly selected from each of the sampled counties as the study sites.
A mixed methods retrospective study including the quantitative and qualitative survey and analysis of the 1-3-7 system components was conducted.
