Question pretext
During the last 12 months, have you experienced 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 a specific health condition or disease. 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. It is also important that the time
period for the symptoms (in the last 12 months) be clearly understood by the respondent and not confused with other time frames used in this section (such as "ever" and "the last 2 weeks").

Wheezing is the most common symptom of asthma. Wheezing can be described as winded breathing, especially with a whistling or rattling or hissing sound as the person breathes out. The episode can last a few minutes or several hours.
