BACKGROUND Malaria transmission in Ethiopia is unstable and seasonal, with the majority of the country's population living in malaria-prone areas. Results from DHS 2005 indicate that the coverage of key malaria interventions was low. The government of Ethiopia has set the national goal of full population coverage with a mean of 2 long-lasting insecticidal(More)
BACKGROUND The SAFE strategy aims to reduce transmission of Chlamydia trachomatis through antibiotics, improved hygiene, and sanitation. We integrated assessment of intestinal parasites into large-scale trachoma impact surveys to determine whether documented environmental improvements promoted by a trachoma program had collateral impact on intestinal(More)
Ethiopia is one of the poorest and least developed countries in the world, endemic for many neglected tropical diseases (NTDs). The Ministry of Health is successfully controlling onchocerciasis through community-directed treatment with ivermectin and has implemented health system changes that would allow extension of integrated NTD control to(More)
Ownership of insecticidal mosquito nets has dramatically increased in Ethiopia since 2006, but the proportion of persons with access to such nets who use them has declined. It is important to understand individual level net use factors in the context of the home to modify programmes so as to maximize net use. Generalized linear latent and mixed models(More)
BACKGROUND Mobile populations present unique challenges to malaria control and elimination efforts. Each year, a large number of individuals travel to northwest Amhara Region, Ethiopia to seek seasonal employment on large-scale farms. Agricultural areas typically report the heaviest malaria burden within Amhara thereby placing migrants at high risk of(More)
BACKGROUND Large cross-sectional household surveys are common for measuring indicators of neglected tropical disease control programs. As an alternative to standard paper-based data collection, we utilized novel paperless technology to collect data electronically from over 12,000 households in Ethiopia. METHODOLOGY We conducted a needs assessment to(More)
Ethiopia reports the third highest number of extrapulmonary TB cases globally, most of which are lymph node TB (TBLN). We investigated the performance of the available diagnostic tests for TBLN. Fine needle aspirate (FNA) and excision biopsy samples from affected lymph nodes were collected from 150 consenting patients with suspected TBLN visiting regional(More)
BACKGROUND Tuberculosis (TB) is still the leading cause of death worldwide accounting for 2.5% of the global burden of disease and 25% of all avoidable deaths in developing countries. OBJECTIVE The aim of the study was to evaluate the impact of the Directly Observed Treatment-Short course (DOTS) programme in Addis Ababa, Ethiopia from 1998-2007. METHODS(More)
Following recent large scale-up of malaria control interventions in Ethiopia, this study aimed to compare ownership and use of long-lasting insecticidal nets (LLIN), and the change in malaria prevalence using two population-based household surveys in three regions of the country. Each survey used multistage cluster random sampling with 25 households per(More)
BACKGROUND Diagnostic tests are recommended for suspected malaria cases before treatment, but comparative performance of microscopy and rapid diagnostic tests (RDTs) at rural health centers has rarely been studied compared to independent expert microscopy. METHODS Participants (N = 1997) with presumptive malaria were recruited from ten health centers with(More)
