Infected surfaces as a source of transmissible material in healthcare settings dealing with COVID-19 patients

The disease COVID-19 has turned out to be a tremendous slayer and has had some of the most devastating impacts on human beings ever seen in history. To overcome this major public health crisis, an understanding of the transmission of the virus underlying this disease is of paramount importance. Evidence suggests that the most common route of transmission for the SARS-CoV-2 virus is likely via direct contact in person-to-person encounter with aerosol droplets. However, the possibility of transmission via contact with fomites from surfaces is a possible route of infection as well. Environmental contamination in rooms with COVID-19 patient has been widely observed due to viral shedding from both asymptomatic and symptomatic patients. Also, in hospitals, SARS-CoV-2 is known to survive on various surfaces for extended periods of time. Because repetitive contact cycles can spread the virus from one surface to the other in healthcare settings, here we evaluated contamination on different types of surfaces commonly found in healthcare settings. Also, based on various datasets, we analyzed the importance of various surfaces in transmission modalities. Based on the findings of this study, decontamination of surfaces that frequently are in touch contact throughout all segments of the healthcare system should constitute an important part of the infection control and prevention of COVID-19. We also recommend the selection of a non-reactive disinfectant for hospital monitors, devices, ventilators and computers so that active surface disinfection can be effected without damage to the devices.
