Introduction: Altered weather patterns and changes in precipitation, temperature and humidity resulting
from climate change could affect the distribution and incidence of cholera. This study is to quantify climateinduced increase in morbidity rates of cholera. Material and Methods: Monthly cholera cases and monthly
temperature, precipitation, and relative humidity data from 2004 to 2014 were obtained from the Malaysian
Ministry of Health and Malaysian Meteorological Department, respectively. Poisson generalized linear models
were developed to quantify the relationship between meteorological parameters and the number of reported
cholera cases. Results: The findings revealed that the total number of cholera cases in Malaysia during the 11
year study period was 3841 cases with 32 deaths. Out of these, 45.1% of the cases were among children below
12 years old and 75% of the cases were from Sabah. Temperature and precipitation gave significant impact on
the cholera cases in Sabah, (p
