Social determinants of long lasting insecticidal hammock-use among the Ra-Glai ethnic minority in Vietnam: implications for forest malaria control Institute of Tropical Medicine

Koen Peeters, X Nguyen Xuan, Joan Muela Ribera, T Ngo Duc, Wim Van Bortel, N Truong Ba, KP Van, H Le Xuan, Umberto D`Alessandro, Annette Erhart, et al.
BACKGROUND: Long-lasting insecticidal hammocks (LLIHs) are being evaluated as an additional malaria prevention tool in settings where standard control strategies have a limited impact. This is the case among the Ra-glai ethnic minority communities of Ninh Thuan, one of the forested and mountainous provinces of Central Vietnam where malaria morbidity persist due to the sylvatic nature of the main malaria vector An. dirus and the dependence of the ...

BACKGROUND: After successfully reducing the malaria burden to pre-elimination levels over the past two decades, the national malaria programme in Vietnam has recently switched from control to elimination. However, in forested areas of Central Vietnam malaria elimination is likely to be jeopardized by the high occurrence of asymptomatic and submicroscopic infections as shown by previous reports. This paper presents the results of a malaria ...

Personal protection by long-lasting insecticidal hammocks against the bites of forest malaria vectors University of Antwerp

Objective  In Southeast Asia, malaria vectors bite outside the houses before bedtime, and forest dwellers rarely use insecticide-treated nets (ITNs). Thus, we tested the protection of long-lasting insecticidal hammocks (LLIH) using Olyset technology against exophagic vectors in two forest villages of Cambodia. Methods  In each village, we conducted two entomological surveys (middle and end of the rainy season), each lasting 10 consecutive ...

Forest goers and multidrug-resistant malaria in Cambodia: an ethnographic study Institute of Tropical Medicine

Melanie Kate Bannister-Tyrrell, Charlotte Gryseels, Suon Sokha, Lim Dara, Noan Sereiboth, Nicola James, Boukheng Thavrin, Po Ly, Kheang Soy Ty, Koen Peeters, et al.

Multidrug-resistant Plasmodium falciparum malaria on the Cambodia-Thailand border is associated with working in forested areas. Beyond broad recognition of "forest-going" as a risk factor for malaria, little is known about different forest-going populations in this region. In Oddar Meanchey Province in northwestern Cambodia, qualitative ethnographic research was conducted to gain an in-depth understanding of how different populations, ...

Malaria transmission and vector behaviour in a forested malaria focus in central Vietnam and the implications for vector control University of Antwerp Institute of Tropical Medicine

Wim van Bortel, Dinh Trung Ho, Xuan Hoi Le, Van Ham Nguyen, Van Chut Nguyen, Dinh Luu Nguyen, Patricia Roelants, Leen Denis, Niko Speybroeck, Umberto d' Alessandro, et al.
Background In Vietnam, malaria is becoming progressively restricted to specific foci where human and vector characteristics alter the known malaria epidemiology, urging for alternative or adapted control strategies. Long-lasting insecticidal hammocks (LLIH) were designed and introduced in Ninh Thuan province, south-central Vietnam, to control malaria in the specific context of forest malaria. An entomological study in this specific forested ...

Long-lasting insecticidal hammocks for controlling forest malaria: a community-based trial in a rural area of central Vietnam University of Antwerp Institute of Tropical Medicine

Ngo Duc Thang, Annette Erhart, Niko Speybroeck, Nguyen Xuan Xa, Nguyen Ngoc Thanh, Pham Van Ky, Le Xuan Hung, Le Khanh Thuan, Marc Coosemans, Umberto d' Alessandro, et al.
Background In Vietnam, malaria remains a problem in some remote areas located along its international borders and in the central highlands, partly due to the bionomics of the local vector, mainly found in forested areas and less vulnerable to standard control measures. Long Lasting Insecticidal Hammocks (LLIH), a tailored and user-friendly tool for forest workers, may further contribute in reducing the malaria burden. Their effectiveness was ...

Outdoor malaria transmission in forested villages of Cambodia University of Antwerp Institute of Tropical Medicine

Lies Durnez, Sokny Mao, Leen Denis, Patricia Roelants, Tho Sochantha, Marc Coosemans
Background: Despite progress in malaria control, malaria remains an important public health concern in Cambodia, mostly linked to forested areas. Large-scale vector control interventions in Cambodia are based on the free distribution of long-lasting insecticidal nets (LLINs), targeting indoor- and late-biting malaria vectors only. The present study evaluated the vector density, early biting activity and malaria transmission of outdoor-biting ...
