| 1 | Has the patient had a cough for ≥3 weeks? |
| 2 | Has the patient had night sweats for ≥3 weeks? |
| 3 | Has the patient lost ≥3 kg in the past 4 months? |
| 4 | Has the patient had fever for ≥3 weeks? |
| 5 | Has the patient had recent contact with another person with active TB? |
| • | If ‘yes’ to question 1: the patient is a TB suspect, perform sputum collection for AFB smear and continue evaluation for TB per the PNILT diagnostic algorithm for pulmonary TB |
| • | If ‘no’ to question 1 but ‘yes’ to any other question: the patient is a TB suspect; continue evaluation for TB guided by clinical signs and symptoms. Refer to national reference hospital if necessary. |
| • | If ‘no’ to all the questions: the patient is not a TB suspect at this time; stop investigations for TB and repeat screening with questionnaire every 3–6 months. |
TB = tuberculosis; AFB = acid-fast bacilli; PNILT = Programme National Intégré de Lutte contre la Lèpre et la Tuberculose.
