Developing the Evidence for and Assessing the Feasibility of Malaria Elimination Efforts among Mobile Migrant Workers in Plantation Settings in Cambodia and Myanmar

Developing the Evidence for and Assessing the Feasibility of Malaria Elimination Efforts among Mobile Migrant Workers in Plantation Settings in Cambodia and Myanmar

Objectives

1. To determine the prevalence of malaria among mobile and migrant plantation workers, including what species is most prevalent and if the resistance gene is found in parasaetimic individuals

2. To determine risk factors unique to this population, including possible transmission sites

3. Test different active 'screen and treat' models in selected plantations to identify the most cost effective, sustainable, and operationally feasible test and treat approaches for plantation workers:

  • Screen and treat on arrival and on exit from the plantation
  • Screen and treat all workers at fixed intervals, such as every three months
  • If epidemiological data demonstrate that the majority of workers harbor malaria parasites, MDA in one site may be done

Abstract

Migrant and mobile populations (MMPs), which comprises a significant proportion of the labour force in Cambodian plantations, is a key affected population and considered a vital target group in both the interruption of artemisinin-resistant parasite transmission and ultimately the elimination of malaria in the country.

The objectives of the operational research project were to answer the following epidemiologic questions:

  1. What is the prevalence of malaria among the plantation population?
  2. How many workers (permanent and temporary) have malaria (symptomatic and asymptomatic)?
  3. What species of malaria is infecting the population?
  4. What is the ratio of P.falciparum vs. P.vivax infections in the above sub-groups?
  5. Is the resistance gene found in the population?
  6. What is the level of resistant P.falciparum genotypes in the above sub-groups?
  7. What are the transmission sites?
