RESUMO
Nutrient profiling entails the classification of foods according to nutritional composition for reasons related to health. It is a critical tool for the implementation of restrictions on the marketing of unhealthy foods to children. This nutrient profile model is designed for use by policy-makers in countries of the Eastern Mediterranean Region for the purposes of restricting food marketing to children

In this paper a dengue transmission mathematical model has been developed. The model assumes that human population is divided into three sub-populations: susceptible, infective and recovered sub-population, while the mosquito population is divided into two sub-populations: susceptible and infective. It is also assumed that the survival rates for humans and mosquitoes decrease with age. Two basic reproduction numbers are derived, namely, the host-to-vector basic reproduction number and the host-to-host basic reproduction number. An illustration on how to estimate the basic reproduction numbers from dengue incidence data is presented using the dengue incidence data during the 2002–2007 dengue outbreaks in Bandung, Indonesia
