Plasmodium Falciparum Malaria Clinical Trial

Official title: Targeting High-risk Populations With Enhanced Reactive Focal Mass Drug Administration: A Study to Assess the Effectiveness and Feasibility for Plasmodium Falciparum and Plasmodium Vivax Malaria in Thailand

Status Recruiting

Clinical Trial Summary

This study assesses the effectiveness of reactive focal mass drug administration (rfMDA), targeting both village and forest working populations, compared to control for reducing the health promotion hospital-level (sub-district) incidence and prevalence of P. falciparum and P. vivax within five provinces in Thailand.

Clinical Trial Description

Thailand currently has a well-developed and robust surveillance system based on detailed mapping of all cases to the village foci level and stratification of response. In fiscal year 2019, 5,833 cases of malaria were reported with 83.0% P. vivax and 12.9% P. falciparum; nine deaths were reported. This represents a 20.8% decrease in total cases from fiscal year 2018. Currently, there are 701 "A1" villages in 44 provinces.

The research proposed here will evaluate the effectiveness and feasibility of enhanced reactive focal mass drug administration, results of which will have direct implications for continued roll out the community-led foci management, providing practical guidance that other malaria programs can utilize. Responding to the malaria among high risk populations is a requirement from the National Malaria Elimination Strategy in Thailand. Additionally, Thailand has experienced outbreaks related to forest work over the past several years, and consequently the Department of Vector Borne Disease (DVBD) is interested in introducing more aggressive parasite elimination strategies, including rfMDA for P. falciparum and P. vivax specifically targeting high-risk populations to interrupt transmission and rapidly accelerate elimination. ;
