Viruses and germs can be found everywhere. After human-to-human transmission, the contaminated surfaces of everyday objects represent the greatest risk of contracting serious diseases. Recent events have shown how dramatically this can develop: During the 2020 corona crisis, more than four million people became infected with the COVID-19 virus within a few months. According to the Robert Koch Institute, this virus can survive for up to six days on inanimate surfaces such as glass, plastic or metal. As a result, the entire world population was isolated and distanced from each other in order to slow the spread of the pathogen.

But even with these drastic measures, the danger is far from over. The virus will continue to exist, as will many other microorganisms which can pose a health risk.
