Impact
The global targets for TB control
By 2015 (Millennium Development Goals)
Goal 6:
combat HIV/AIDS, malaria and other diseases
Target 8:
to halt and begin to reverse the incidence of malaria and

The Berlin Declaration on tuberculosis
 Berlin, 22 October 2007
 49 country delegations
 Commitment to:
- strengthen TB control
- adopt the Stop TB Strategy
- ensure sustainable financing
20
The Stop TB Strategy
1)
Pursue high-quality DOTS expansion
and enhancement (political commitment,
quality bacteriology, guaranteed treatment,
ensured drug supply, monitoring and evaluation)
2)
Address TB-HIV, MDR-TB and other
challenges (prisoners, other risk groups)
3)
Contribute to health system
strengthening
4)
Engage all care providers (public-private,
international standards)
5)
Empower patients and communities
(ACSM, community participation, patients’
charter)
6)
Enable and promote research
21
The Stop TB Strategy: International Standards for TB Care
Diagnosis
Standard 1: TB suspicion if 2-3 weeks productive cough
Standard 2: always 2-3 sputum samples for microscopy
Standard 3: appropriate specimen if extrapulm. TB suspect
Standard 4: sputum microscopy in suggestive chest x-ray
Standard 5: SS- with microscopy, x-ray, antibiotics; culture
Standard 6: SS- children with x-ray, history, skin test; culture
Treatment
Standard 7: doctor caring of patient’s adherence to treatment
Standard 8: standardized regimens, doses, FDC
Standard 9: arrangements (incl. DOT) tailored to each patient
Standard 10: follow-up with sputum microscopy (2nd,5th,end)
Standard 11: written complete medical record maintained
Standard 12: HIV counselling and testing (routine or ad hoc)
Standard 13: access to antiretroviral treatment
Standard 14: assess risk of drug resist., if yes DST for H,R,E
Standard 15: 4-drug regiment for 18 months if drug resistance
Public health
responsibility
Standard 16: all contacts screened for latent/active TB
Standard 17: reporting of TB detection and treatment22outcome

Health systems: opportunities for TB delivery at PHC level
 Suspect TB and react quickly
 Collect 3 sputum samples from each suspect
 Smear samples and/or send samples to
designed laboratory for microscopy
 Refer TB suspects for early TB diagnosis
 Provide directly observed treatment (DOT)
 Coordinate support to TB patients
 Trace treatment defaulters
 Refer patients with adverse drug reactions
 Keep TB records and reporting
 Monitor populations at special risk of TB
 Educate patients, families, community
 Check TB contacts (symptoms, skin testing)
 Provide BCG vaccination
