Objective : Knowing spatial distribution of diphtheria and to identify risk factor
of diphtheria at Malang City, Province of East Java.
Methods: Analytic observational study is a case-control design. Samples were
taken with a consecutive sampling technique with the number of each case and
control samples of 90 individuals. Data analysis using the Mc. Nemar and

diphtheria, while the independent variable is the immunization status, occupancy
density, distance to health facilities, place the activity and mobility.
Results: The pattern of distribution of diphtheria in Malang City are clustered at
coordinate 6675248, 912 050 UTM Zone 49S, radius 3621.03 meters. Risk factors
for diphtheria in Malang City is place the activity p = 0.003 (OR = 5.4 and 95%
CI 1.802 to 16.492) and mobility p = 0.003 (OR = 3.5 and 95% CI 1.558 to
8.152).
Conclusion: The place of activity is the most dominant risk factor in the
