| Summary: | Dengue isoneofthemostrapidlyspreadingdiseaseandhasbecomeamajor
health concernintropicalandsub-tropicalcountries.Environmentalfactors,
suchaslowandhighlandsclimates,havebeenknowntohavestrongcorre-
lations withtheendemicityoftheregion.DenguetransmissioninSemarang
(elevation2:45 m)andMalangcities(elevation440 ???? 670 m)arestudiedba-
sed ontheincidencedatafromthetwocities.Host-vectormodelsofthetype
SIR-SI areconstructedtosimulatethetransmissionofdengue.Withnodata

byuseofspiraldynamicoptimization,theinfectionratesforbothcitiesare
