Microbial contamination on hospital lift buttons: a metagenomic perspective
Lift buttons in the hospitals, recognized as high-touch fomites, contributed to the transmission of hospital-acquired infections (HAIs) due to frequent contact by individuals from diverse backgrounds and professions. Despite scheduled cleaning with dedicated chemicals, concerns remained regarding th...

Lift buttons in the hospitals, recognized as high-touch fomites, contributed to the transmission of hospital-acquired infections (HAIs) due to frequent contact by individuals from diverse backgrounds and professions.
