2 referral lab. just passed QA.

5.566 TB lab.

59% (3.284) EQAS,

75% good result

TB-MDR

Among new patients,

resistance to any drug 17.1%

MDR-TB 1.8%.

Retreatment cases,

Resistance 34.3% and

MDT 17.1%.

WHO estimated 6900 cases are MDR TB (annual incidence).

Total notification MDR-TB was 428, (0.12% coverage).

TB-HIV

HIV prevalence in new TB is 3.3%.

~ 1% TB patients

know their HIV status.

Among HIV positive,

only 29% enrolled on

ART.

National Strategy 2016 Toward a free-TB, healthy, just and self- reliant society

Technical Strategies

1.Scaling-up and improve quality DOTS

2.Addressing TB/HIV, MDR-TB, & the needs of poor and vulnerable

3.Engaging all public and private

providers in implementation of ISTC.

4.Empowering TB patients &

communities

National Strategy 2010-2016

Functional Strategies

1.Strengthening health system, HRD and TB control program management

2.Increasing commitment of central and local government

3.Enhancing research, development and

utilization of strategic information

Conclusion

TB Operational Research Group (TORG)

Under the NTP

Facilitate operational research (OR)

Increase capacity to conduct OR through intensive courses

Review TB research proposals submitted to NTP

Provide technical assistance in OR at National level.

Facilitate implementation of OR results in program

Scope of the TORG Network

Evaluation of implementation of Xpert-Mtb-Rif

National level OR

5 Xpert deployed in 2012, 10 more in 2013

Aiming for HIV and MDR-TB

Increase D/ yield,

faster detection MDR TB

Hesitation rely only xpert

Culture still needed

TB prevalence survey

TB prevalence survey Preliminary findings

Smear-positive TB prevalence higher than previously estimated*

Probably more sensitive screening, & diagnosis

Prevalence in rural > urban

Prevalence peaked in 25-34 age. Ongoing significant transmission?

Gaps between prevalence and notifications are greater in men and oldest age
