Long-term acceptability, durability and bio-efficacy of ZeroVector(®) durable lining for vector control in Papua New Guinea

This study examined the acceptability, durability and bio-efficacy of pyrethroid-impregnated durable lining (DL) over a three-year period post-installation in residential homes across Papua New Guinea (PNG).; ZeroVector(®) ITPS had previously been installed in 40 homes across four study sites representing a cross section of malaria transmission risk and housing style. Structured questionnaires, DL visual inspections and group interviews (GIs) were completed with household heads at 12- and 36-months post-installation. Three DL samples were collected from all households in which it remained 36-months post-installation to evaluate the bio-efficacy of DL on Anopheles mosquitoes. Bio-efficacy testing followed WHO guidelines for the evaluation of indoor residual spraying.; The DL was still intact in 86 and 39% of study homes at the two time periods, respectively. In homes in which the DL was still intact, 92% of household heads considered the appearance at 12-months post installation to be the same as, or better than, that at installation compared to 59% at 36-months post-installation. GIs at both time points confirmed continuing high acceptance of DL, based in large part of the perceived attractiveness and functionality of the material. However, participants frequently asserted that they, or their family members, had ceased or reduced their use of mosquito nets as a result of the DL installation. A total of 16 houses were sampled for bio-efficacy testing across the 4 study sites at 36-months post-installation. Overall, combining all sites and samples, both knock-down at 30 min and mortality at 24 h were 100%.; The ZeroVector(®) DL installation remained highly acceptable at 36-months post-installation, the material and fixtures proved durable and the efficacy against malaria vectors did not decrease. However, the DL material had been removed from over 50% of the original study homes 3 years post-installation, largely due to deteriorating housing infrastructure. Furthermore, the presence of the DL installation appeared to reduce ITN use among many participating householders. The study findings suggest DL may not be an appropriate vector control method for large-scale use in the contemporary PNG malaria control programme

Perceptions of incentives offered in a community-based malaria diagnosis and treatment program in the Highlands of Papua New Guinea

What motivates community-based health workers to provide care in rural and remote areas, often on a voluntary or casual basis, is a key question for program managers and public health officials. This paper examines how a range of incentives offered as part of the Marasin Stoa Kipa program, a community-based malaria diagnosis and treatment program that has been implemented since 2007 within a major oil and gas development area in Papua New Guinea, are perceived and critiqued by community-based health workers. Nineteen interviews and seven focus group discussions with the workers who deliver services and members of the communities served by the program, conducted between November 4 and 25, 2015, reveal a pattern of mixed motivations and changes in motivation over time. This can be attributed partly to the unique social and economic circumstances in which the program is operating. Changes in the burden of disease as well as in global and national health services policy with implications for local level program operations also had an impact, as did the nature of relationships between program managers, community-based health workers, and program beneficiaries. Overall, the findings suggest that while financial and in-kind incentives can be a useful tool to motivate voluntary or minimally-compensated community-based health workers, they must be carefully structured to align with local social, economic, and epidemiological realities over the long-term

Koita and Motu Landscapes and Seascapes of Caution Bay

A loss of place-names, and of the knowledge of history those named places hold, is effectively a significant cultural loss, and for this reason it was deemed important to record named places at Caution Bay before those localities were permanently altered. Therefore, named, culturally meaningful places within and near the Caution Bay study area were recorded in conjunction with local Koita and Motu community members in 2008-2010 (Figures 5.1 and 5.2). This mapping was undertaken in two steps, the first consisting of opportunistic recording of place names during early, preliminary stages of fieldwork in 2008 and 2009; and the second a focused study undertaken in early 2010 explicitly aimed at recording place names and their cultural significance in the face of imminent developments that would forever transform the landscape. This chapter presents the results of these studies
