To understand how malaria could be eliminated in the original hyperendmic area for malaria along international borders in Yunnan Province, malaria situation and control were described on the basis of seven phases. At last the experiences and lessons of the program that reduced border malaria from hyperendmicity to malaria-free status were summarized. Malaria control and elimination area were particularly difficult in the Yunnan border.

Article Synopsis
  • Malaria poses a significant health threat in the China-Myanmar border area, and understanding the genetic diversity of the parasite Plasmodium falciparum can help improve control strategies.
  • The study collected blood samples from 2006 to 2011, analyzing various isolates of the malaria parasite using specific genetic techniques to reveal the presence of different allele types.
  • Results showed a dominance of specific families for the merozoite surface proteins (MSP1 and MSP2), high multiplicity of infections, and a positive correlation between multiplicity and parasite density, indicating substantial genetic variation among the malaria strains in the region.

Objective: To analyze the genetic diversity of based on the mitochondria DNA cytochrome c oxidase subunit Ⅰ (mtDNA COⅠ) gene as a molecular marker in Lincang City of Yunnan Province, so as to provide the scientific data for monitoring in local areas.

Methods: The genotypes and polymorphisms of 38 specimens of collected from Mengding Town of Lincang City were analyzed by sequencing COⅠ gene. The phylogenetic tree and genetic distances were produced based on the haplotypes from GenBank and the present study by using the neighbourjoining method with the software MEGA version 6.

Background: This paper seeks to assess the function of malaria control consultation and service posts (MCCSPs) that are located on the border areas of Yunnan province, P.R. China, as a strategy for eliminating malaria among the mobile and migrant population in these areas.

Objective: To understand the control status of malaria at hotspots in Yingjiang County and provide measures for malaria elimination in the China-Myanmar border areas of Yunnan Province.

Methods: A survey was made in 4 villages with indigenous malaria cases or imported cases in Nabang and Tongbiguan of Yingjiang County in Yunnan Province in June and July 2015. Peripheral blood samples were collected from the neighboring residents around patients and examined by malaria rapid diagnostic test (RDT).

Objective: To analyze blood samples from patients with falciparum malaria and vivax malaria in border areas of Yunnan Province, using 18S rRNA-based nested PCR, and compare 18S rRNA sequences.

Methods: Blood or filter blood samples with positive microscopic results for Plasmodium falciparum or P. vivax infection were collected from Laza, Nankajiang, Mangdong and Nawei of Myanmar, and from Mengla, Tengchong and Yingjiang of Yunnan Province between 2004 and 2011.

Objective: To assess the in vitro sensitivity of Plasmodium falciparum to chloroquine, piperaquine and pyronaridine in China-Myanmar border area.

Methods: Fifty-one blood specimens of P. falciparum isolates were collected from Laza City of Myanmar during September to December in 2009, and the sensitivity of the parasites to the drugs was detected by Rieckmann's in vitro microtest.
