Prevalence of malaria infection in Butajira area, south-central Ethiopia

<p>Abstract</p> <p>Background</p> <p>In 2005, the Ethiopian government launched a massive expansion of the malaria prevention and control programme. The programme was aimed mainly at the reduction of malaria in populations living below 2,000 m above sea level. Global warming has been implicated in the increase in the prevalence of malaria in the highlands. However, there is still a paucity of information on the occurrence of malaria at higher altitudes. The objective of this study was to estimate malaria prevalence in highland areas of south-central Ethiopia, designated as the Butajira area.</p> <p>Methods</p> <p>Using a multi-stage sampling technique, 750 households were selected. All consenting family members were examined for malaria parasites in thick and thin blood smears. The assessment was repeated six times for two years (October 2008 to June 2010).</p> <p>Results</p> <p>In total, 19,207 persons were examined in the six surveys. From those tested, 178 slides were positive for malaria, of which 154 (86.5%) were positive for <it>Plasmodium vivax </it>and 22 (12.4%) for <it>Plasmodium falciparum</it>; the remaining two (1.1%) showed mixed infections of <it>Plasmodium falciparum </it>and <it>Plasmodium vivax</it>. The incidence of malaria was higher after the main rainy season, both in lower lying and in highland areas. The incidence in the highlands was low and similar for all age groups, whereas in the lowlands, malaria occurred mostly in those of one to nine years of age.</p> <p>Conclusion</p> <p>This study documented a low prevalence of malaria that varied with season and altitudinal zone in a highland-fringe area of Ethiopia. Most of the malaria infections were attributable to <it>Plasmodium vivax</it>.</p

Report on Training of Health Professionals on Climate and Health

The role of climate in health is currently enjoying a high profile among the international community in terms of demonstrating climate risk management and adaptation to a changing climate. The effect of climate variability and change on heath is a serious issue for most sub-Saharan African countries. Among the diseases that have public health importance in Ethiopia are malaria, meningitis and acute watery diarrhea. Understanding the relationship of climate and health in Ethiopia would be a tremendous help in early containment of these diseases. In Ethiopia, before the establishment of a Climate and Health Working Group (CHWG), which includes the Federal Ministry of Health and the National Meteorological Agency among other partners, the sharing of information among the two key players was minimal. The goal of this working group is to create a climate-informed health sector that routinely requests and uses appropriate climate information to improve the effectiveness of health interventions. In order to meet its goals, the working group, in collaboration with the International Research Institute for Climate and Society (IRI), organized a six-day training course for health professionals on climate and health. In this training, the Summer Institute course "Climate Information for Public Health" (held for the past two years at IRI in New York), was adapted and implemented. The Summer Institute has involved four Ethiopian participants, one from the National Meteorological Agency (NMA), and three from the Ministry of Health. They played a key role in facilitating some of the course lectures themselves and in identifying local professionals who could also contribute to the curriculum. The general goal of the six-day training was to build the national capacity in order to utilize climate information for decision-making in the health sector at national and regional state levels. The training was comprised of three components: core lectures, practical sessions, and short recap presentations by the participants. Sixteen participants were involved in the training. The selection of the participants was done in consultation with the Federal Ministry of Health. Participants came primarily from the Public Health Emergency Management Units of regional and federal health bureaus and were chosen for their roles in the decision-making around the prevention and control of climate-sensitive diseases. Three types of evaluation were carried out, a pre- and post-test, as well as an overall evaluation. The pre- and post-test helped to evaluate the level of knowledge about climate and health before and after the training. The latter helped in evaluating the organization of the overall training. Generally, the evaluations revealed that the training helped to increase the knowledge of the links between climate and health, as well as the use of climate information for decision-making in the public health sector. This training is the first of its kind organized in Ethiopia, especially at a national level. Most of the participants agreed on the suitability of the content, design and delivery of the course and showed their interest in organizing similar training initiatives in their respective home institutions. It is possible to recommend that this training should be extended to the regional health bureau level, with the already trained participants taking the primary responsibility of facilitating these follow-on activities with the close support of the CHWG. The collaboration of the regional branch offices of the National Meteorological Agency, with respect to using climate information, would play a crucial role in this endeavor. The most important point is to sustain this training and update its contents accordingly. The future research agenda and evidence generation efforts of the CHWG and its members should also focus on other climate sensitive diseases. Even though participants did not indicate there were always established ties to local universities in different parts of the country, these potential partnerships should be addressed in sharing the knowledge of the use of climate information for public health decision-making and in prioritizing locally important diseases. The training was held at UNECA, Addis Ababa, Ethiopia, between November 31st and December 5th, 2009. Financial and technical support was provided by IRI with funding from the Google.org sponsored project "Building Capacity to Produce and Use Climate and Environmental Information for Improving Health in East Africa.

The effect of ivermectin® on fertility, fecundity and mortality of Anopheles arabiensis fed on treated men in Ethiopia.

BACKGROUND: Insecticide resistance is a growing threat to malaria vector control. Ivermectin, either administered to humans or animals, may represent an alternate strategy to reduce resistant mosquito populations. The aim of this study was to assess the residual or delayed effect of administering a single oral dose of ivermectin to humans on the survival, fecundity and fertility of Anopheles arabiensis in Ethiopia. METHODS: Six male volunteers aged 25-40 years (weight range 64-72 kg) were recruited; four of them received a recommended single oral dose of 12 mg ivermectin and the other two individuals were untreated controls. A fully susceptible insectary colony of An. arabiensis was fed on treated and control participants at 1, 4, 7, 10 and 13 days post ivermectin-administration. Daily mosquito mortality was recorded for 5 days. An. arabiensis fecundity and fertility were measured from day 7 post treatment, by dissection to examine the number of eggs per mosquito, and by observing larval hatching rates, respectively. RESULTS: Ivermectin treatment induced significantly higher An. arabiensis mortality on days 1 and 4, compared to untreated controls (p = 0.02 and p < 0.001, respectively). However, this effect had declined by day 7, with no significant difference in mortality between treated and control groups (p = 0.06). The mean survival time of mosquitoes fed on day 1 was 2.1 days, while those fed on day 4 survived 4.0 days. Mosquitoes fed on the treatment group at day 7 and 10 produced significantly lower numbers of eggs compared to the untreated controls (p < 0.001 and p = 0.04, respectively). An. arabiensis fed on day 7 on treated men also had lower larval hatching rates than mosquitoes fed on days 10 and 13 (p = 0.003 and p = 0.001, respectively). CONCLUSION: A single oral dose of ivermectin given to humans can induce mortality and reduce survivorship of An. arabiensis for 7 days after treatment. Ivermectin also had a delayed effect on fecundity of An. arabiensis that took bloodmeals from treated individuals on day 7 and 10. Additional studies are warranted using wild, insecticide-resistant mosquito populations, to confirm findings and a phase III evaluation among community members in Ethiopia is needed to determine the impact of ivermectin on malaria transmission

Knowledge and perception towards net care and repair practice in Ethiopia.

BACKGROUND: Long-lasting insecticidal nets (LLINs) are a key malaria control intervention. Although LLINs are presumed to be effective for 3 years under field or programmatic conditions, net care and repair approaches by users influence the physical and chemical durability. Understanding how knowledge, perception and practices influence net care and repair practices could guide the development of targeted behavioural change communication interventions related to net care and repair in Ethiopia and elsewhere. METHODS: This population-based, household survey was conducted in four regions of Ethiopia [Amhara, Oromia, Tigray, Southern Nations Nationalities Peoples Region (SNNPR)] in June 2015. A total of 1839 households were selected using multi-stage sampling procedures. The household respondents were the heads of households. A questionnaire was administered and the data were captured electronically. STATA software version 12 was used to analyse the data. Survey commands were used to account for the multi-stage sampling approach. Household descriptive statistics related to characteristics and levels of knowledge and perception on net care and repair are presented. Ordinal logistic regression was used to identify factors associated with net care and repair perceptions. RESULTS: Less than a quarter of the respondents (22.3%: 95% CI 20.4-24.3%) reported adequate knowledge of net care and repair; 24.6% (95% CI 22.7-26.5%) of the respondents reported receiving information on net care and repair in the previous 6 months. Thirty-five per cent of the respondents (35.1%: 95% CI 32.9-37.4%) reported positive perceptions towards net care and repair. Respondents with adequate knowledge on net care and repair (AOR 1.58: 95% CI 1.2-2.02), and those who discussed net care and repair with their family (AOR 1.47: 95% CI 1.14-1.89) had higher odds of having positive perceptions towards net care and repair. CONCLUSIONS: The low level of reported knowledge on net care and repair, as well as the low level of reported positive perception towards net repair need to be addressed. Targeted behavioural change communication campaigns could be used to target specific groups; increased net care and repair would lead to longer lasting nets
