Ba.kground: The purpose of our study is to develop a.quite precise ma.hema.ica. model which describes epidemics sprea. in a.country with non-uniform popula.ion density.

It wa. shown tha. the epidemiologica. situa.ion in the Republic of Bela.us is well described by three wa.es, which sprea. respectively in la.ge cities with the highest popula.ion density (the first wa.e), in medium-sized cities with a.popula.ion of 50−200 thousa.ds people (the second wa.e), in sma.l towns a.d rura. a.ea.
