This table lists the most common causes of healthcare-acquired infections (HAI) in Europe, according to the European Centre for Disease Prevention and Control (ECDC). The ECDC conducted a study from 2011–2012 on vectors of healthcare-associated infections in 273,753 patients in 1,149 hospitals in 29 European countries. The table also contains data on the efficiency of blue light inactivation of microbes collected from different sources. Although different microbes respond differently to blue light, it is nevertheless fatal to all of them.
