4.4.3 Contact tracing of household contacts

Contact tracing is critical to identify further cases of MDR/RR-TB, prevent ongoing transmission and ultimately work towards the global endTB strategy. Assessment should be offered for household contacts where feasible, especially for children aged below 5 years. Measures available for screening should include symptom assessment, chest X-ray and sputum testing (preferably using WHO-recommended molecular tests) (33).
