Effect Of Climate And Sanitation Of Rats Population And Index Flea As Indicator Detection Yersinia pestis In Port Surabaya

Background: International Health Regulations (IHR) classifies plague as the disease is likely to recur, and has the potential to cause epidemics and extraordinary events. Objectives: analyze the influence of climate and level of sanitation to the population of rats and fleas index as an indicator of yersinia pestis in the port of Surabaya. Methods: analytic observational research with cross sectional design through testing time series and regresion linier. Population in this study are data on the number of mice caught and the number of fleas were found and observed in the laboratory of the Port Health Office of Surabaya.  Results: results of linear regression analysis with p=0,001 for the influence of humidity on the population of rats, p=0,036 for the influence of solar radiation on the rat population, the value of p=0,033 for the influence of rainfall on the level of sanitation, and p=0,037 for influence the level of sanitation of the rat population, so the hypothesis is accepted. Conclusions and suggestions: There is the influence of humidity and solar radiation on the population of rats and fleas index, rainfall factors affect the level of sanitation, sanitation factors influence the rat population.
