Beliefs and perceptions about malaria interventions may greatly affect the implementation of interventions at community level. This study explored the perception of community health workers in Lilongwe on barriers to effective malaria control service delivery and utilisation at the community level and identified a number of factors that health workers cited as barriers and challenges to effective implementation of malaria interventions in Lilongwe.

Research: Duration of the mosquitocidal effect of ivermectin

Ivermectin (IVM) reduces the lifespan of malaria-transmitting mosquitoes after feeding on humans treated with IVM but limited data are available on the exact duration of the mosquitocidal effect of IVM. Daily mosquito feeding assays were conducted to determine this. Mosquito mortality was 70-100% when mosquitoes fed on mice, rats, or cynomolgus monkeys 1-2 days after the last IVM administration. The findings reported here, of a pronounced but short-lived mosquitocidal effect, makes the timing of IVM administration crucial to form a useful addition to anti-malarial drugs.

Research: Perceptions and practices of the Konso community (South-west Ethiopia) relating to malaria: implications for control

Using a structured questionnaire, focus group discussions and in-depth interviews, this study aimed to gain deeper insight on how the Konso community in Ethiopia perceives malaria and manages the disease. Although knowledge about malaria was above average it surfaced that the use of herbal home remedies is widespread. It is argued that this practice warrants further investigation to validate the efficacy and safety of plant preparations that are employed.

PhD thesis: Effect of preventive supplementation with zinc and other micronutrients on malaria and diarrhoeal morbidity in African children

Multi-nutrient supplementation may be unsafe in malaria-endemic areas, particularly in young children with iron deficiency. Thus the recommendation by the World Health Organization that iron supplements should be administered routinely to iron-deficient infants in settings with adequate access to anti-malarial treatment is insufficiently supported by evidence and should be reconsidered. The results presented in this PhD thesis underscore that supplementation or home fortification, even when targeting deficient subgroups in settings with access to adequate primary care, should not be recommended in malaria-endemic areas until their safety has been demonstrated.

Opinion: Paradigm shifts in malaria study and control

This article describes some major events in the history of malaria research and control, some of the investigators involved, and how they promoted their ways of the fight against this disease. Every episode or moment is calibrated with the theory of science, developed by Thomas Kuhn. His idea of paradigms in science and sudden shifts is helpful for the understanding of what steered the various levels of malaria research. It also may keep investigators on the alert of dead ends and breakthroughs in future.

This book review focuses on the life and work of Professor Wallace Peters. It is autobiographical and describes his career that covers half a century as well as his personal life during that period. 'Four passions' is a book for anyone interested in malaria and leishmaniasis and presents numerous issues of interest, many of which will be recognizable to scientists working on malaria today.

Research: Malaria pattern observed in the highland fringe of Butajira, Southern Ethiopia: a ten-year retrospective analysis from parasitological and metrological data

The authors of this article aimed to determine malaria occurrence and its association withmeteorological variables in the highland fringe of Butajira, Southern Ethiopia from parasitological and metrological data. They found no significant association between malaria occurrences and meteorological variables between January 2000 and December 2009; therefore non-climatic factors together with climatic variables should be assessed to know the spread and intensity of malaria in the highland fringe of Butajira. This report also warrants the Ministry of Health to include highland areas in its current malaria control campaign so as to address those non-endemic foci of the country.

Hypothesis: Solar net fan: a potential tool to enhance bednet usage in hot climates

Hot and humid climatic conditions may affect bednet utilisation. This hypothesis article presents a novel and unique approach to increase the comfort of bednet occupants. It describes a solar energy-powered fan that can be placed inside bednets to increase the airflow and provide a cooling effect. A preliminary cost analysis of such a device is presented.

Experimental huts have played a long and illustrious role in the study of mosquito vectors of disease. Here we present a design of a novel, cheap, 12 sided, experimental hut based on the African roundhouse. The panels covering each side can open and act as a door and above each panel there is a shutter that can also open. This allows for a great combination of possible openings for the study of entry and exit behaviour of mosquitoes. Preliminary results describing the exit behaviour of Anopheles funestus when four of the panels were open are described.

Research: The AMFm and Medicine Diversion: Good intent enabling corrupt practices

Increased donated and subsidised medicines for malaria are saving countless lives in Africa, but there is probably increasing theft and diversion of those medicines. The impact of medicine diversion is unknown but potentially dangerous and may bolster criminal networks and increase medicine stock outs. This study demonstrates that diversion is widespread; diverted subsidised medicines were found in 11 of 14 cities investigated, and in four of those, over half the pharmacies researchers visited had diverted subsidised malaria products.
