WHO estimates approximately 234 million major surgeries globally (i.e. operative procedure, involving significant risks to the patient). SSO (Surgical Site Occurences) affect up to 25% of patients, undergoing operative procedures, with the subset of surgical site infections (SSIs) being the most common. 1 in 20 patients is affected by hospital associated infection.
SSI account for 31-36% of all health care associated infections, being the major cause of morbidity (data CDC 2013, 2016, ECDC 2014, 2016)
