Researchers from the University of Nottingham and the Institute for Health and Welfare in Finland have published a curious and interesting article about the bioburden analysis in public places such as undergrounds, public toilets and airports. The scientists have found the highest bioburden in airport security checkpoints. Specifically, the study–published by the journal BMC Infectious Diseases–has highlighted that trays used to x-ray scan hand baggages contain the highest concentration of pathogens responsible for viral infections in the respiratory system. The detected viruses include rhinovirus (40% of surfaces), coronavirus (30%), adenovirus (20%) and influenza A virus. In an interview to the NYT, the researchers have stated that their purpose is to raise awareness among authorities about the need for good hygiene practices in airports, which can be real virus carriers, thanks to the very high number of passengers using them, which has reached 4.1 billion in 2017.
