BACKGROUND Tuberculosis (TB) in migrants is an ongoing challenge in several low TB incidence countries since a large proportion of TB in these countries occurs in migrants from high incidence countries. To meet these challenges, several countries utilize TB screening programs. The programs attempt to identify and treat those with active and/or infectious(More)
This paper describes an action framework for countries with low tuberculosis (TB) incidence (<100 TB cases per million population) that are striving for TB elimination. The framework sets out priority interventions required for these countries to progress first towards "pre-elimination" (<10 cases per million) and eventually the elimination of TB as a(More)
Contact investigation to identify individuals with tuberculosis and latent infection with Mycobacterium tuberculosis is an important component of tuberculosis control in low tuberculosis incidence countries. This document provides evidence-based and best-practice policy recommendations for contact tracing among high- and medium-priority contacts in a(More)
OBJECTIVE To compare drug-resistant variants from untreated (naive) and treated patients infected with clade B or C virus. METHODS Consecutive samples (165) from patients throughout Israel were analyzed. All those in the treated group were failing highly active antiretroviral therapy. RESULTS There were 87 clade B (14 naive) and 78 clade C (20 naive)(More)
'Recreational' substances used among men having sex with men, and their association with risky unprotected anal intercourse (RUAI) were examined--for the first time in Israel--in an internet-based questionnaire assessing knowledge, practices and motivation. Between March and May 2005, 2873 participants completed the entire questionnaire. Of the total, 669(More)
Data on the efficacy of drugs for preventing multiple drug resistant tuberculosis (MDR-TB) in people at risk after close contact with patients is lacking. In a systematic review, we found only two small cohort studies that addressed this question. 1 The aim of the present study was to describe the incidence of MDR-TB disease in people who were in close(More)
SETTING Right of entry may sometimes be denied to immigrants because of the threat of tuberculosis. During 1990-2000 some 1050000 immigrants, mostly from countries highly endemic for TB, arrived in Israel, a low prevalence country. Nevertheless, TB rates in Israel have remained low. OBJECTIVE To emphasise the challenge beyond technical competence for TB(More)
SETTING Israel has implemented a new tuberculosis (TB) control programme in response to the rise in the incidence of tuberculosis due to immigration in the last decade. It complies with World Health Organization guidelines, and also includes specific measures addressing the needs of immigrants. We describe the new programme and compare the outcome of(More)
Restriction fragment length polymorphism analysis with IS6110 and DR-r probes was used to study 69 Mycobacterium tuberculosis isolates obtained from Israeli patients and new immigrants from the former Soviet Union and Ethiopia. DNA fingerprinting identified unique patterns for almost all isolates, indicating that most patients were infected with a unique(More)
