Abstract: Objective To evaluate the measures and achievements of malaria control in Tengchong City during 2010-2015. Methods The malaria control information on epidemiology, foci disposal, blood detection of febrile patients, and medical treatment during 2010-2015 in Tengchong City was collected and analyzed using Microsoft Excel 2010. Results In 2010-2015, 1 654 malaria cases were reported in Tengchong City, including 18 indigenous cases, 22 domestically mobile cases, and 1 614 imported cases from abroad, of whom 1 584 cases (98.1%) were imported from Myanmar. Most of the cases were vivax malaria(76.2%, 1 261/1 654). No indigenous malaria cases were reported from 2013 to 2015. Blood test was conducted for 80 655 febrile patients, with a positive detection rate of 2.1%(1 654/80 655). The positive detection rate was highest in 2010 (2.8%, 700/24 861), lowest in 2011(1.4%, 341/23 623), and decreased from 2012 to 2015. In addition, 1 654 cases were directly reported through online system. The 24-h case report rate during 2013-2015 was 100%. A total of 1 191 cases were investigated. The 3-day case investigation rate during 2013-2015 was 100%. A total of 1 351 endemic foci were investigated. The 7-day foci disposal rate during 2014-2015 was 100%. Conclusion No indigenous transmission has been reported for three years in Tengchong City. However, the imported malaria remains an important problem.
