Analysis of fatality due to cholera epidemics in Tuliszków parish in 1852.

INTRODUCTION

Little is known about the correlation between age, gender-distribution and fatality rate during cholera epidemics.

AIM: To analyze the change in the fatality rate with regard to age and gender during cholera epidemics in 1852 in Tuliszków Parish.

MATERIAL AND

METHODS

Data for the present study were retrieved from the archives. Information on fatal cases was obtained from the records of Tuliszków Parish - The Register of Deaths (1851-1879). Age, gender of the deceased and place of residence in Tuliszków Parish were analyzed. Data from the year in which the epidemic occurred (1852) and year preceding it (1851) were compared using Pearson's χ2 test.

RESULTS

A total of 3200 persons lived in the Roman Catholic Parish of Tuliszków during cholera epidemic in 1852. Having compared to the control year (1851), fatality rate distribution changed statistically significantly in the epidemic year (1852); (χ2=27.5665, p=0.0011). In particular, it applied to males (χ2=28.9476, p=0.0007). Irrespective of the gender, the highest increase of the fatality rate was observed in the 10-25 age group (χ2=5.0375, p=0.0248) while infant fatality rate decreased (χ2=19.2789, p=0.0000).

CONCLUSIONS

Cholera epidemic resulted in a significant change of fatality rate in infants, males and the youth. Death of both parents aged up to 45 years old contributed to an increase in the number of orphans.
