Brazzaville – Access to tuberculosis (TB) diagnosis as a crucial first step to detect and treat the disease remains a huge challenge in Congo, where around half of the estimated 21 000 TB cases are detected every year. To support the country scale up testing, World Health Organization (WHO), with financing from the Global Fund, has provided GeneXpert diagnostic machines in the capital Brazzaville and Pointe-Noire, the country’s second city. The machines have improved the rate of testing eight-fold, allowing for timely enrolment of TB patients on treatment.
