One of the non medical factor of nosocomial infections is environmental factor, such as temperatures and humidity, which enhance bacterial growth.

The samples were 30 wards in inpatient unit of RS PKU Muhammadiyah Jogjakarta. VIP wards were excluded. Data were analyzed by chi-square test.
Results: Bivariate analysis found that there is a significant correlation between temperature and wards humidity with air germs number in inpatients unit class I, II, and III of RS PKU Muhammadiyah Jogjakarta; with p=0.007, which is less than alpha (á=0.05), RP=2.25, CI=1.039-4.874 for temperature; and p=0.028, which is less than alpha (á=0.05), RP=1.968, CI=1.039-4.874 for humidity.
