During the last 12 months, have you experienced any of the following…
For this set of questions, the interviewer must read out a series of symptoms and determine if the respondent had any of those symptoms in the last 12 months. The point of asking symptom-related questions is to screen those individuals who might have tuberculosis (TB). Because there could be a number of symptoms that characterise a given health condition, and because some symptoms may be common to different conditions, it is important that the interviewer probe for each symptom to see whether the respondent may have an active disease.
During the last 12 months, have you had blood in your phlegm, or have you coughed blood?
Warning: these figures indicate the number of cases found in the data file. They cannot be interpreted as summary statistics of the population of interest.
Coughing blood, or having blood in the sputum or phlegm, is a symptom that is very specific to tuberculosis. If the respondent is unsure of the meaning of phlegm, explain that this is the substance spit out from a deep cough (or use another term in local colloquial language).
