The decline of malaria in Finland--the impact of the vector and social variables.

ABSTRACT:

Background

Malaria was prevalent in Finland in the 18th century. It declined slowly without deliberate counter-measures and the last indigenous case was reported in 1954. In the present analysis of indigenous malaria in Finland, an effort was made to construct a data set on annual malaria cases of maximum temporal length to be able to evaluate the significance of different factors assumed to affect malaria trends.

Methods

To analyse the long-term trend malaria statistics were collected from 1750-2008. During that time, malaria frequency decreased from about 20,000-50,000 per 1,000,000 people to less than 1 per 1,000,000 people. To assess the cause of the decline, a correlation analysis was performed between malaria frequency per million people and temperature data, animal hu
