Detection of the drug resistance molecular markers for falciparum and vivax in Longitudinal follow-up samples collected in Shwegyin Township, Bago Region that is Artemisinin Resistance Containment Tier I.
This study is longitudinal and observational cohort study to detect the drug resistance molecular markers in asymptomatic malaria infected local residents in study site. Only local residence who are not migrants, are recruited in the study and active and passive surveillance have been carried out within one year observation period. At the time of enrollment, blood film examination, rapid diagnosis test (RDT) testing have been done all together with the collection of the venous blood (about 1-2 mL) that would be used for molecular analysis later. All of the RDT or microscopy positive cases were treated according to the National Malaria Treatment Policy in Myanmar. A total of at least 1000 participants have been recruited in the study. Active case detection has been done in every three months. The venous blood were used for molecular based detection of the asymptomatic malaria infection by using High-throughout pooling strategy. All of the positive samples, (falciparum and vivax), have been checked for drug resistance molecular analaysis compared with the previously collected symptomatic malaria infection cases in the same region.
32 studies on the registry are indexed under Asymptomatic Infections; 6 are open to participants now.
This study's enrollment of 1,179 is above the median of 740 across 12 observational studies indexed under Asymptomatic Infections.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Number of the Asymptomatic malaria infection
Number of the asymptomatic malaria infection by molecular method in the sample collected from apparently healthy individuals. It have been done by nested PCR based method. Number of the asymptomatic infection will be finished in March 2016. (up to up to 5 months after last samples collection)
Time frame: 2016 March
Number of the cases that showed drug resistance molecular markers in asymptomatic malaria infection
K13, Pffd, Pfmdr2 and Pfcrt markers for falciparum and Pvcrt-O, Pvdhps, Pvdhfr and Pvmdr1 for vivax asymptomatic infections.The target sequences will be analysed to detect the specific single nucleotide polymorphism (SNPs). Molecular marker analysis will be done as soon as after asymptomatic infection have been confirmed. It will be finished in 2016 April. (up to 6 months after last sample collection)
Time frame: 2016 April
Prevalence of the different Malaria Antibody in local resident in Myanmar
Malaria antibody that against the malaria parasites will be assessed by using high sensitive protein microarray. Total overall prevalence will be assessed and time to time change of the antibody status will be observed. It will be started in April until December 2016.(Up to 14 months after last sample collection)
Time frame: 2016 December
