Isolation precautions based on different categories and particular highly transmissible disease were being fused into groups containing precautions for infections transmitted by the airborne, droplet and contact routes of transmission (Tansmission-Based Precautions).
Izolacijske ukrepe na osnovi kategorij in na osnovi posamezne bolezni pa so združili v ukrepe pri aerogenem prenosu, kapljičnem prenosu in prenosu z dotikom ter jih poimenovali Ukrepi na osnovi prenosa (Transmission-Based Precautions).
