ALRI mortality from SFU has most likely declined in the last decades, and is likely to decline further even without a reduction in SFU or adoption of improved stoves. This comes about from a reduction in ALRI case fatality rates through for instance improved case management and reduction in malnutrition rates even in the event that incidence of morbidity does not decline. 4 In the countries with the highest SFU mortality (in the sample of 13 countries), u5 child mortality rates have declined substantially since 1960 but appear to have stagnated in several of the Sub-Saharan countries. .
