Interviewer instructions
It is recognized that consistent use of insecticide-treated mosquito nets (ITN) decreases the incidence of clinical malaria and malaria-related deaths, especially in very young children. Consequently, many countries are now instituting programmes that promote the use of ITNs. There are various types and brands of mosquito nets. Some require regular treatment with insecticide. Others are factory-treated and do not require re-treatment for 6 to 12 months (pre-treated) 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, whether and when they were last treated with insecticide and whether household members use the nets when they sleep at night. Note that 'cake covers' or baby nets that are used to keep flies off infants, usually during the daytime, are not considered mosquito nets. These nets cannot be treated with insecticide. Window screens are also not considered mosquito nets. --- Circle the code corresponding to the response given. If 'No', skip to the next module.
