Abstrakt: Nosocomial infections (NIs) remain a global health burden with higher incidence in Africa. We assessed building conditions and risk of NIs from microbial contamination of appliances and surfaces in a Specialist hospital in Southwest Nigeria. The study sampled 120 surfaces in 12 wards during normal occupational activities. Moulds on ceilings and dusty surfaces were observed in the wards. Microbial burden (1038.0 × 10 5  cfu) peaked in the ICU but was lowest (446.9 × 10 5  cfu) in the male ward. Bacteria counts ( × 10 5  cfu) of 234.7, 199.7 and 67.0 were measured on ICU tap, doorknob and ECG, respectively. Theatre diatomy machine, anaesthetic machine and operating lamp had bacteria counts ( × 10 5  cfu) of 40.0, 85.0 and 109.0, respectively. Highest total fungal count (58.2 × 10 5  cfu) was recorded on ICU trolley handle, switch and suturing tube. Our study established surfaces as major environmental routes for NI transmission in this health care facility.
