Environmental Survival Times of Pathogens Causing HAI

A Facciola et al. European Review for Medical and Pharmacological Sciences 2019;23:1266-1278.
"Scientific evidence supports the hypothesis that hospitals can act as an important reservoir of many nosocomial pathogens in several environments such as surfaces, medical equipment and water systems."

Environmental survival time of pathogens causing HAIs:
E. coli 1.5 h to 16 mo;
P. aeruginosa 6 h to 16 mo;
Klebsiella spp. 2 h to 30 mo;
Acinetobacter spp. 3 d to 5 mo;
Methicillin R Staph aureus 7 d to 7 mo;
Vancomycin R Enterococci 5 d to 4 mo;
C. difficile > 5 mo:
C. albicans 1 d to 120 d; and
Norovirus 8 h to 7 d.

Organisms of HAI concern:
Acinetobacter baumannii;
Carbapenem-resistant Enterobacteriaceae (CRE);
Pseudomonas aeruginosa;
Methacillin-resistant Staph aureus (MRSA);
Vancomycin-resistant enterococci (VRE); and
Clostridium difficile.
