The COVID-19 pandemic has brought increased awareness to a number of factors for germ transmission. One of them is the surfaces we touch and what material they’re composed of. Dr. Charles Gerba, professor of microbiology at the University of Arizona, has recently conducted studies to gauge contamination levels on high-touch surfaces such as gas pump handles and ATM buttons. However, not all materials are created equal when it comes to the transmission of germs. The WHO has acknowledged that COVID-19 only lives on copper for four hours (as compared to days on plastics, wood, silverware, doorknobs, ceramics, glass, stainless steel, etc.).
