Despite being a priority population in malaria elimination, there is scant literature on malaria-related behavior among gold miners. This study explores the prevalence and factors influencing malaria prevention, care seeking and treatment behaviors in Guyana gold mining camps. A cross sectional survey was conducted among adult gold miners living in mining camps in the hinterland Regions 1 (Barima-Waini), 7 (Cuyuni-Mazaruni), and 8 (Potaro-Siparuni). Multivariable logistic regressions explored factors associated with miners’ self-report of mosquito net use, prompt care-seeking; self-medication; and testing for malaria. A third of miners used a mosquito net the night preceding the survey and net use was higher among those who believed that net use was the norm in their camp (aOR: 3.11; 95% CI:1.65, 5.88). Less than half (45%) of miners had a fever in the past 12 months, among whom 36% sought care promptly, 48% tested positive for malaria while 54% self-medicated before seeking care. Prompt care-seeking was higher among miners with high malaria knowledge (aOR: 1.44; 95% CI: 1.01, 2.05). Similarly, testing rates increased with secondary education (aOR: 1.71; 95% CI: (1.16, 2.51), high malaria knowledge (aOR: 1.45; 95% CI: 1.02, 2.05), positive beliefs regarding malaria transmission, threat, self-diagnosis, testing and treatment, and, trust in government services (aOR: 1.59; 95% CI (1.12, 2.27) and experience of a prior malaria episode (aOR: 2.62; 95% CI: 1.71, 4.00). Self-medication was lower among male miners (aOR: 0. 52; 95% CI: 0.32, 0.86). Malaria prevention and care seeking behaviors among miners are somewhat low and influenced by mosquito net usage, perceived norms, malaria knowledge and prior episode of confirmed malaria. Study findings have implications for malaria interventions in the hinterland regions of Guyana such as the mass and continuous distribution of insecticide treated nets as well as community case management initiatives using trained malaria testing and treatment volunteers to curb malaria transmission among remote gold mining populations. These include efforts to identify and address gaps in distributing mosquito nets to miners and address miners’ barriers to prompt care seeking, malaria testing and treatment adherence. Targeted social and behavior change messaging is needed on net acquisition, use and care, prompt care-seeking, malaria testing and treatment adherence. Additional efforts to ensure the overall sustainability of the community case management initiative include increased publicity of the community case management initiative among miners, use of incentives to promote retention rates among the community case management volunteer testers and public private partnerships between the Guyana Ministry of Health and relevant mining organizations.

Abstract Background Artesunate-sulfadoxine-pyrimethamine (ASSP) is the frontline artemisinin combination therapy (ACT) in India. Random, irrational, subtherapeutic artemisinin doses and self-medication with ACT along with predominance of sulfadoxine-pyrimethamine resistance parasite invoked a strong possibility of emerging artemisinin-resistant malaria parasites. Methods This study involved 226 patients with uncomplicated Plasmodium falciparum infection who had successfully completed the 42 days follow-up after ASSP combination therapy from April 2014 to January 2016. We assessed the ASSP treatment efficacy by evaluating parasite clearance half-life, pfkelch13, and other (pfdhfr, pfdhps, pfmdr1, pfcrt) gene mutations and survival of parasites as detected by an ex vivo ring-stage survival assay (RSA). Findings Slow-clearing infections with longer parasite clearance half-lives (>5 hours) were observed in 12% isolates. Cure rate after ASSP treatment was declining to about 84.1%. ASSP failure was recorded in 15.9% (early treatment failure, 7.9%; late treatment failure, 7.9%) of isolates. In sum, 24 patients (10.6%) had parasite clearance half-lives greater than 5 hours with pfkelch13 polymorphism after 441 codon; in 15 of those patients (6.6%), parasites had not cleared by 72 hours after initiation of therapy. Median ex vivo ring-stage survival rate of these isolates was very high (12.2%; 95% confidence interval [CI], 10.9–13.8) from that of cured patients (0.9%; 95% CI, 0.09–1.07). Of these 15 patients, 13 patients had pfkelch13 G625R polymorphism, whereas 2 patients contained R539T polymorphism. As per the World Health Organization guideline, these 15 isolates were true artemisinin-resistant isolates. Interpretation Identification of artemisinin-resistant isolates in India together with new mutations and increasing combination therapy failures blow alarms for urgent malaria control.

Malaria is endemic in French Guiana, especially within the gold mining community working illegally. Gold miners travel to remote camps in the forest to carry out their activities, exposing themselves to the presumed contamination area. This paper presents the results of a qualitative case study of the Malakit project, a free distribution of self-diagnosis and self-treatment kits, along with appropriate training/information from health facilitators, at resting sites in Brazil and Suriname on the borders with French Guiana. This study documents how Malakit is part of the care trajectory of gold miners. The data was collected using three methods: 1) on-site observation; 2) semi-structured individual interviews (n=26); 3) semi-structured group interviews (n=2). The results inform us that Malakit responds to the need for treatment and facilitates access to care. Gold miners say they trust the facilitators and receive accurate explanations. The majority of participants find the kit easy to use and to carry and explanations given were sufficient, although some people needed to be reminded how to use it once in the forest. Results remind us that malaria among illegal gold miners in French Guiana is a question of social inequalities in health, where the interaction of the health, social, economic and political contexts of Brazil and French Guiana influence exposure to numerous risk factors. Thus, malaria intervention practices such as Malakit cannot be carried out without considering the complexity generated by social inequalities in health.
