Expanding DOTS under NTP since 2002
-- Issued Yunnan TB control and prevention plan 2002-2010 and 2011-2015
by Yunnan provincial government

TB/HIV Co-infection Control
 Screening TB for HIV/AIDS patients in 2012
 TB symptoms screening rate: 90.32 % (53914/59689)
 Physical check-up with chest X-ray or sputum smear:
69.36 % (41403/59689)
 The positive rate :0.84% (346/41403)
 HIV antibody screening test for TB patients in 2012
 HIV screening rate: 73.59% (18898 /25678)
 The positive rate : 0.47% (88 /18898)
M/XDR-TB Control

Government commitment: set up very clear targets in
Yunnan provincial TB control and prevention plan 20112015.
– Improve TB lab capacity: Over 60% county-level labs with
sputum culture skill, 100% prefecture-level labs with DST
(solid medium).
– Build up MDR-TB clinical centers for regular diagnosis and
treatment: cover 50% prefectures.
– MDR-TB suspects screening: 60%
M/XDR-TB Control
Laboratory Capacity Strengthening
• Building DST lab network in whole province
• Purchased lab equipments for culture and DST in 2007 and 2008 for
each county-level and prefecture-level lab
• biosafety cabinet (classⅡ), autoclave, incubator, refrigerator etc.
• Special training: 294 lab technicians were trained in 2009 and 2010
• By the end of 2012
• 128 county-level labs (99%) were qualified for sputum culture
• 16prefecture-level labs (100%)were qualified for DST
• Rapid identification of bacteria at the provincial level Gene-Xpert
M/XDR-TB Control
Yunnan Provincial TB Treatment Center
With the support of Global Fund, set up first MDR-TB clinical
center in Kunming in 2012
Goal: Provide free diagnosis and treatment of MDR-TB
cases in Kunming, and being a top center of M/XDR-TB of
whole province
M/XDR-TB Control Efforts
Commitment from Yunnan provincial government for
CAP-TB program
•All levels of health bureaus supported this program, and want to
integrate it with NTP.
•Provided 40 thousand RMB as counterpart funding for each year
•Provided funding to purchase reagents for GeneXpert test
•We are re-designing and rebuilding and isolating the wards for
MDR-TB patients based on suggestion from CAP-TB.
• Yunnan CDC paid the fee about 200 thousand RMB.
M/XDR-TB Control
• Total 48 MDR-TB cases were diagnosed and 26 of
them received anti-TB treatment.
– Reasons for not receiving treatment: patient
decline, be too busy, living too far, afraid of
stigma or default during waiting for DST result
etc.
• 2 XDR-TB cases were diagnosed and both of them
received anti-TB treatment.

Main Challenges of TB control
in Yunnan Province
Main Challenges of TB control in Yunnan
• High TB burden in Yunnan province
– Near 25,000 PTB cases reported every year
– Ranked second among 39 statutory reported infectious
diseases since 2005
– Annual decrease rate of reported TB incidence is much
slower than national average from 2002 to 2012
• Yunnan province: 1.89%
• National average: 3.40%
– Much bigger regional difference of TB burden
• Remote rural area: Zhao tong
Main Challenges of TB control in Yunnan
 High-risk groups lack of active and efficient TB screening
– TB examination of elder people has not integrated into
community-based health service.
– No special funds to support the active screening for migrant
population .
– TB screening among diabetes just began 2 month at 10
communities supported by CAP-TB project.
– Lower case detection for HIV/AIDS population.
Main Challenges of TB control in Yunnan
• Very weak community support for TB control
– Longer delay when seeing a doctor for TB patients and
suspects

Main Challenges of TB control in Yunnan
• Low awareness of TB prevention and control in public
– A KAP survey in 2010 showed:
– Knowledge rate of the public was 43.5% in Yunnan
– National average rate was 57%.
• DOT can not be conducted due to lack of support of
community in some region
– For example, Zhenxiong county: total 2258 PTB cases
including 299 re-treatment cases in 2012, which meant
very poor follow-up and treatment.
Main Challenges of TB control in Yunnan
• There was no mature model of community-based
TB/MDR-TB management.
– Only focusing on technical part of medicine rather than
patients feelings
– Low detection of MDR-TB patients
– Low rate of enrolled MDR-TB patients for receiving secondline anti-TB drug treatment
Main Challenges of TB control in Yunnan
• Most MDR-TB patients are very poor and feel
desperate
– based on face to face interview of total 24 MDR-TB
patients supported by CAP-TB project
– 61% cases with less than 300 dollars monthly income
– 12% cases without any medical insurance
– Only 30% cases with strong confidence of successful
treatment in future
