B1.2 The TB surveillance system is designed to account for a minimum of variables for reported TB cases ± + Adoption of WHO definitions (2013)
B1.3 All data to be submitted periodically has been received and processed at the national level x + 100% of reports received in DHIS2 (2018)

B1.7 The number of TB cases reported is consistent internally ± ± Quarterly reports show discrepancies in places that are corrected during supervision.
B1.8 All cases of tuberculosis diagnosed are reported x x Tuberculosis is under surveillance and is considered a priority for the Ministry of Health. There is no ministerial decree making TB disease notification mandatory.
B1.9 People have good access to health care x x - The under-five mortality rate (probability of dying before the age of 5 per 1000 live births) is 86 per 1000 in 2017

Quality and coverage of civil state facts
B1.10 The civil registration system is of excellent quality and provides broad national coverage x x Guinea has a civil registration system, and there is a register of deaths at the morgue level where deaths are recorded. The causes of death are not recorded.
Surveillance of Multidrug-resistant Tuberculosis
B2.1 Surveillance data provide a direct measure of multi-drug resistant TB cases among new cases x x In our context, not all patients are systematically tested. The Xpert MTB test is indicated for a number of cases. No drug resistance studies have yet been conducted in Guinea
Tuberculosis/HIV surveillance
B2.2 Surveillance data provide a direct measure of HIV prevalence in TB patients    The HIV test coverage was 90% in 2018
Tuberculosis surveillance in children
B2.3 Surveillance data for children reported to be TB (aged between 0 and 14 by definition) are reliable and accurate, AND all cases of childhood tuberculosis diagnosed are reported x x The ratio of (0–4:5–14 years) patients was 0.38 in 2018
