On surfaces: ready, set, go!

Door handles, light switches, keyboards & the computer mouse (especially with shared desks), coffee machines and printers – they all are in direct contact with employees who may have just sneezed into their hands, or who have come straight from the metro or toilet, and are therefore hot spots for bacteria and viruses.

Even seemingly clean surfaces can be contaminated. If pathogens are passed on to the nose, mouth or eyes via the hands, employees can sometimes fall ill very quickly, depending on the germ involved.

Pathogens can survive on surfaces for some time – sometimes even months.1 Indirect contact infection via surfaces plays a secondary role in the transmission of diseases such as influenza or COVID-19, compared to airborne infection. Nevertheless, this route should also be reliably closed off in order to actually prevent any spreading.

Highly effective against pathogens and gentle to the surface:

mikrozid® sensitive and mikrozid® universal


Diarrhea-type diseases are mainly transmitted by contact or indirect contact infection. The pathogens, mostly noro and rota viruses, can also be picked up via toilet seats or other commonly used areas such as coffee kitchens or the canteen.

To prevent these indirect contact infections reliably, it is essential to disinfect surfaces regularly. mikrozid® sensitive and mikrozid® universal are particularly gentle on surfaces and equipment – including touchscreens, smartphones and tablets. Fast and widely effective (against E. coli, salmonella, rota, influenza and corona virus) within 1 oder 2 minutes, respectively

Study 1:


One study where a potential spread of viruses through the workplace was simulated using viruses harmless to humans (MS2 phages) demonstrated the sources of risk: The refrigerator, drawer handles, water taps in the break room, the handle bar for opening the door at the main exit and the soap dispenser in the ladies’ toilet were the most contaminated areas.2

Study 2:


Another study reports a noro virus outbreak among employees at a car dealership. Twelve of the 16 employees fell ill with this severe gastrointestinal infection following a joint meeting. Initially, a sandwich machine was suspected to be the source of the infection. However, several employees then reported seeing a toddler with diarrhea in the toilets at the car dealership shortly before lunch. And indeed, the same strain of the virus that knocked out the staff was identified in the child – as well as in the baby changing facilities at the car dealership. Contrary to what might be thought at first glance, this sudden outbreak of gastrointestinal disease was therefore not due to food, but to the environment.3
