Objective: To find correlations between climate variations (temperature, rainfall, humidity,\udand wind speed) and the prevalence of rotavirus diarrhea, particularly evinced by hospital\udadmission.\udMethods: Stool specimens were obtained from under five-year-old children suffering from\udacute diarrhea at the Dr. Hasan Sadikin General Hospital over the period from April 2009 to\udDecember 2012. Stool specimens were obtained from the sick children within 24 h of their\udhospital admission. Weather information was obtained monthly.\udResults: From 945 stool specimens, rotavirus was positively identified in 427 (45.2%) of them.\udCorrelation of rotavirus diarrhea prevalence to temperature, rainfall, humidity, and wind speed\udwere amounted to r = -0.427, r = 0.101, r = 0.536 and r = -0.069, respectively. No significant\udcorrelation could be determined to link the prevalence of rotavirus to either the dry and the wet\udseason (P = 0.939). A slight seasonal climate variation was shown in the dry season, where the\udrotavirus was found to be positive in 250 out of 552 specimens (45.3%). However, in the wet\udseason, only 177 out of the 393 specimens (45.0%) were proved to be positive.\udConclusions: Our study showed that rotavirus is found year-round, and has a negative\udcorrelation to temperature, a moderate correlation only to humidity, but no significant\udcorrelation at all to either rainfall or wind speed
