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

1. Burden of disease and

progress towards 2015

targets

Page 4: Global TB control - Stop TB Partnership · Global TB control: ... Cambodia Malaysia Indonesia Eritrea Thailand Philippines Bangladesh Myanmar Cambodia Ghana Kenya ... 88 …

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

Page 5: Global TB control - Stop TB Partnership · Global TB control: ... Cambodia Malaysia Indonesia Eritrea Thailand Philippines Bangladesh Myanmar Cambodia Ghana Kenya ... 88 …

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

China and India for the first time in 2011

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

Page 32: Global TB control - Stop TB Partnership · Global TB control: ... Cambodia Malaysia Indonesia Eritrea Thailand Philippines Bangladesh Myanmar Cambodia Ghana Kenya ... 88 …

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
