Interviewer instructions
There are various types and brands of mosquito nets. Some require regular treatment with insecticide; others are factory treated and do not require any treatment for 6-12 months (pre-treated type) or 36 months (permanent type). By observing the mosquito nets yourself, you should be able to identify what brands or types of mosquito nets households own, but respondents may not always permit you to enter the sleeping areas where the nets are found. Your supervisor may provide you with photographs to help you to distinguish different brands of mosquito nets. In order to assess the effectiveness of mosquito net use in preventing malaria, we need to gather accurate information on the type of nets, and whether and when they were last treated with insecticide. Identify the type of net in the dwelling and circle the corresponding number on the questionnaire. If the respondent is not sure whether a net is one of these brands, try to observe the net, if possible. If it is not possible to observe the net(s), use the pictures you were given to aid in identification. If it is a permanently treated net (codes '11' or '12'), skip to the next module. If it is a pre-treated net (codes '21' or '22'), skip to ML14. If it is some other brand that is not listed, circle '36' and fill in the other brand name in the space provided. If the respondent does not know the type of net or the brand, circle '98' for 'DK brand'.
