Ecology and health of the population in the city of Tselinograd in 1964 (the case of infectious hepatitis and typhoid fever outbreak)

The article examines the outbreak of infectious hepatitis and typhoid fever in 1964 in the city of Tselinograd. During the development of virgin and fallow lands a large number of people arrived in northern Kazakhstan. The urban infrastructure that existed at that time was not always able to provide the population with the necessary services, which often led to failure and the emergence of a difficult epidemiological situation. On the basis of statistical materials, the authors show an increase in the incidence of hepatitis and typhoid fever in the population in a short time, and also analyse the accompanying reasons. It is concluded that a gross violation of sanitary rules when choosing a place for the technical water intake and its connection to a drinking water supply on the territory of the railway junction was the main cause of the epidemic.
