- Absolute risk of nosocomial infection in conservatively vs liberally transfused patients: 12% vs 17%
- Bacterial contamination of products, especially platelets
- 1 of 2000-3000 platelet transfusions results in bacterial infection
- Gram-positive bacteria (e.g. staph due to contamination with skin puncture during collection
- Gram-negative bacteria (e.g. e. coli) due to asymptomatic bacteremia in donor
- Anaplasmosis, brucellosis, ehrlichiosis have all been documented
- Parasitic infection: rare but reported. Those reporting recent travel to malaria-endemic regions are barred from donation
- Viral infections
- Prion disease
