The most effective measures to prevent malaria transmission are based on vector control through the use of insecticides. However, insecticides exert a strong selective pressure on mosquito populations for insecticide resistance.

Malarias caused by Plasmodium that commonly infects female Anopheles mosquitoes, which feed on human blood and act as a disease vector. It has been a worldwide important public health problem from ancient times.

Antimalarial drug resistance is a significant obstacle to the control and prevention of malaria globally. The molecular markers associated with antimalarial drug resistance can provide early warnings about the emergence of resistance.

The "1-3-7" approach was well implemented in Henan Province from 2012-2018. Over this study period, a total of 1,294 malaria cases were detected and reported, and all cases were diagnosed and reported within 1 day with 99.

Angola was the main origin country for the imported malaria in Henan Province, China. Antimalarial drug resistance has posed a threat to the control and elimination of malaria. Several molecular markers were confirmed to be associated with the antimalarial drug resistance, such as , , , , and This study evaluated the drug resistance of the 180 imported isolates from Angola via nested PCR using Sanger sequencing.

Objective: To retrospectively overview the diagnosis and treatment of malaria during 2010-2014 in Henan Province and understand the role of medical institutions in imported malaria control.
Methods: Information on malaria epidemic situation as well as its diagnosis and treatment during 2010-2014 in Henan Province was collected from the infectious disease surveillance system and information management system for the prevention and treatment of parasitic disease. Descriptive analysis was performed to determine the role of medical institutions in the reporting, diagnosis and treatment of malaria.

Objective: To evaluate the capability of malaria parasite detection among professionals from Class III malaria endemic counties of Henan Province in 2012. METHEDS: The capacity assessment of professionals from the Centres for Disease Control and the medical institutions was done in September to December 2012. The content of the assessment included malaria knowledge (including malaria etiology, clinical manifestation, diagnosis, treatment and epidemiology and so on, 100 scores as full marks and 60 as passing score), making blood slides of Plasmodium (4 slides in 1 hour, including Giemsa staining, 40 scores as full marks and 24 as passing score) and identification of species with microscopy (6 slides, 8 min per slide 60 scores as full marks and 36 as passing score).
