Hygiene Management // Surface Disinfection

Disinfect several times daily

With its new interim guidance regarding surface hygiene in connection with COVID-19, the World Health Organization (WHO) wants to “reduce any role that contaminated surfaces may play in the transmission of SARS-CoV-2”. Surfaces in rooms where a patient with a suspected or confirmed COVID-19 infection is present must, according to the experts, be cleaned and disinfected several times. In this regard, the sequence of cleaning or disinfection is also important.

The role that surfaces which have been contaminated with SARS-Cov-2 play in the transmission of the novel pulmonary disease is not yet fully understood. Previous studies that investigated the survival of the novel coronaviruses were based on experimental studies and laboratory experiments. Now, studies on the real contamination of surfaces in Chinese COVID-19 hospitals and laboratories prove that frequently touched surfaces in particular pose a transmission risk.

Increased frequency of cleaning

With this in mind, the World Health Organization (WHO) has published new interim guidance on surface cleaning and disinfection in connection with COVID-19. Surfaces in facilities associated with the care of suspected or confirmed COVID-19 patients should be cleaned or disinfected up to three times daily. In the guidance published, the WHO goes beyond the daily wipe disinfection recommended by the Robert Koch Institute (RKI).
