Maternal morbidity A simple recall method will be used to assess morbidity in the mothers. They will be asked to recall, over the month preceding the interview, any days they were ill enough to have their usual daily activities restricted. If they have experienced restricted day illness they will be asked about key symptoms (cough, diarrhoea, urinary discomfort and fever). A medical history will be collected at baseline to capture information about maternal chronic illnesses as well.
