to TB among women and children
Katherine Floyd

World Health Organization
42nd Union World Conference on Lung Health
Stop TB Symposium
Lille, 26 October 2011
Overview
Launched 11 October
1. The burden of disease caused by TB
and progress towards 2015 targets
2. Progress in implementing and
financing TB care and control Comparisons with targets in Stop TB
Partnership's Global Plan 2011–2015
3. TB in women and children What global notification and survey data
tell us
Progress in applying the Task Force framework for assessment
of TB surveillance data, as of July 2011
Major progress in measuring and
estimating disease burden
96 country consultations in 2 years
17 African countries plus India and China in past year
April 2009 – June 2010
December 2010 – July 2011
Countries for which direct measurements of TB mortality are available, 2010Direct measurements of mortality national vital registration (90 countries) + mortality surveys (India)
91 countries, 46% estimated global TB deaths,
Up from 89 countries with 8% global TB deaths in 2010

Estimates of TB burden among
women and children
Estimated 3.2 million (range 3.0–3.5 million) new
cases among women in 2010
Estimated ~10% of cases are among children
Estimated ~320,000 deaths among HIV-negative
women in 2010 and ~0.5 million deaths among
women including HIV-associated TB
1. Reporting of notification data disaggregated
by age and sex from all countries Case or patient-based electronic recording and
reporting
2. Prevalence surveys in Africa
3. Studies to quantify "under-reporting" of
cases among children and actions to reduce
under-reporting (and over-diagnosis)
Next steps for better assessment
of TB among women and children
