Why do we need to control infections in ICUs?
The COVID-19 pandemic continues to put a significant burden on global healthcare resources. Because droplets were first thought to be the predominant mechanism of transmission for SARS-CoV-2, the main focus of infection control was on preventing direct human-to-human transmission through social distancing, face masks, hand washing, and cleaning of virus-contaminated surfaces
However, new evidence suggests that airborne transmission plays a significant role
Particularly in enclosed situations like healthcare facilities and in the lack of clear proof, major public health authorities have accepted the evidence of airborne spread and the urgent need to reduce spread to both healthcare personnel and uninfected patients has resulted in significant structural and organizational adjustments in intensive or critical care units (ICUs)
Health-care personnel, their families, and hospitalised patients are at a greater risk of acquiring SARS-CoV-2
Close contact with patients, particularly coughing and the use of aerosol-generating procedures is linked to this risk. WHO estimates that health-care professionals were responsible for 2–35 percent of all COVID-19 cases, depending on the country's resources and reporting methods.
