BACKGROUND Delayed diagnosis and treatment of tuberculosis (TB) results in severe disease and a higher mortality. It also leads to an increased period of infectivity in the community. The objective of this study was to determine the length of delays, and analyze the factors affecting the delay from onset of symptoms of pulmonary tuberculosis (PTB) until the(More)
BACKGROUND Early diagnosis and immediate initiation of treatment are essential for an effective tuberculosis (TB) control program. Delay in diagnosis is significant to both disease prognosis at the individual level and transmission within the community. Most transmissions occur between the onset of cough and initiation of treatment. METHODS A systematic(More)
Drug resistance is a major obstacle to effective TB control program performance. In this study, we assessed the prevalence of primary drug resistance in Mycobacterium tuberculosis (Mtb) isolates in Amhara Region, Ethiopia. A total of 112 Mtb isolates from cases with newly diagnosed pulmonary TB were subjected to drug susceptibility testing (DST) in a(More)
BACKGROUND Early detection and treatment of TB is essential for the success of TB control program performance. The aim of this study was to determine the length and analyze predictors of patients', health systems' and total delays among patients attending a referral hospital in Bahir Dar, Ethiopia. METHODS A cross-sectional study was conducted among newly(More)
BACKGROUND Health care seeking is a dynamic process that is influenced by socio-demographic, cultural and other factors. In Ethiopia, there are limited studies regarding the health seeking behaviour of tuberculosis (TB) suspects and TB patients. However, a thorough understanding of patients' motivation and actions is crucial to understanding TB and the(More)
OBJECTIVE To assess an active case-finding strategy for the identification of smear-positive pulmonary tuberculosis (TB) in a rural district of Amhara Region, Ethiopia. METHODS Study kebeles (smallest administrative units) were randomly selected in a cross-sectional study. House-to-house visits involving individuals aged >or=15 years in all households of(More)
INTRODUCTION Ethiopia has a growing private health sector. In recent years, the directly observed treatment short course (DOTS) strategy was initiated in selected private health facilities in the country. The objective of the present study was to assess knowledge and practice of private practitioners in tuberculosis (TB) control in Amhara Region, Ethiopia.(More)
Recent genotyping studies of Mycobacterium tuberculosis in Ethiopia have reported the identification of a new phylogenetically distinct M. tuberculosis lineage, lineage 7. We therefore investigated the genetic diversity and association of specific M. tuberculosis lineages with sociodemographic and clinical parameters among pulmonary TB patients in the(More)
Background. Weak health systems pose many barriers to effective tuberculosis (TB) control. This study aimed at exploring health worker's and TB control program coordinator's perspectives on health systems challenges facing TB control in West Gojjam Zone, Amhara Region, Ethiopia. Methods. This was a qualitative descriptive study. Eight in-depth interviews(More)
BACKGROUND A major goal of tuberculosis control programs is to stop community transmission of Mycobacterium tuberculosis. However, this can not be rapidly accomplished because, in endemic areas, most of the population is already infected, serving as a reservoir that continuously contributes to the pool of infectious cases. Tuberculin surveys are the main(More)
